Dark Climate - Now and Coming

Seas rising much faster, super storms in the coming decades, doubling and re-doubling of polar ice melt - new Hansen paper. We talk with co-author Isabella Velicogna, and with Ottawa climate scientist Paul Beckwith. Also: the Canadian super fire at Fort McMurray: can the tar sands burn? Radio Ecoshock 160511

WELCOME

It's about 90 degrees, or 29 Celsius, outside my door, in the early Canadian spring. Crazy weather, the same super heat that set northern Alberta on fire. We'll talk about the the climate connection, and ask the question: "can the tar sands burn?" - later in this program.

First, though it seems less exciting, we're going to begin a series about the most important scientific paper of this new century. Dr. James Hansen led a team of international scientists who completely revise the science of climate change. Seas rising much faster, super storms in the coming decades, doubling and re-doubling of polar ice melt. It's a climate thriller, and we all get to live in the new disturbed world. I'm Alex. Welcome to Radio Ecoshock.

PAUL BECKWITH ON THE PAPER BY HANSEN ET AL

The scientist who warned the U.S. Congress about dangerous climate change in 1988 is back. Dr. James Hansen, who recently retired as head of NASA's Goddard Institute, says we're going to be hit much sooner and harder than we've been told by mainstream science. Hansen says the two degree Centigrade upper limit to human-induced global warming, as agreed at the Paris climate summit in December 2015 - is not just unsafe. It is plainly very dangerous for humans and all life as we know it.

James Hansen and more than a dozen other world scientists published a monumental 66 page scientific paper in March. The full title is: "Ice melt, sea level rise and superstorms: evidence from paleoclimate data, climate modeling, and modern observations that 2 o C global warming could be dangerous". Find the abstract (very informative) here, or read the full text version here.

A transcript of Hansen's "Video Abstract" can be found here at Columbia University,

The public has hardly heard the news, and there's a lot to hear.

I've called up a regular Radio Ecoshock correspondent to help us sort out what this new Hansen paper says. Paul Beckwith teaches climate science at the University of Ottawa. He has two Masters degrees and is developing his PhD thesis on abrupt climate change.

So James Hansen, perhaps the world's foremost climate scientist, leads this new and shocking intrepretation of recent science - and the political and public reaction is... crickets basically. Why is it taking so long for people to get this?

The paper covers so much - polar ice melt, sea level, super storms, ocean mixing. It's so long, that few people have read it all. Maybe this master paper is a response by Dr. Hansen and his co-authors to the obvious short-comings of reports from the Intergovernmental Panel on Climate Change. It's like an alternative climate report.

I come away with one big place to start: it's not global heating like one or two degrees, but the big changes in the ocean we don't hear about. Jim Hansen suggests we worry less about the temperature outside, and more about the ocean energy imbalance. I hope to have more on that in a coming show.

There's a pattern at both Poles where the surface water may actually be getting cooler, and it's warmer down below. Paul explains that stratification, and how the warmer water can get under the grounding lip of glaciers, moving more ice toward the sea. The new Hansen paper suggests that warmer water at the ice grounding lines matters more in Antarctica, and less on Greenland.

The more conventional modelling scientists are still suggesting 1 to 2 meters of sea level rise by the end of this century. This new paper finds there could be 1 meter of sea level rise by 2050, and several meters by 2100. That means the end of many major coastal cities around the world. Paul Beckwith goes further. If we just compute the doubling time of ice melt, he says that adds up to 7 meters of sea level rise by 2070. Beckwith has a video on You tube where he explains how that could be possible. Watch that original video here, and his update here.

THE COMING SUPER STORMS

Let's get to one of James Hansen's favorite topics, the coming super storms. To understand this, we have to go back about 130,00 years. That's a time when, Hansen says, differences in ocean temperatures led to the formation of giant waves that swept boulders weighing over a thousand tons high up on Caribbean islands. The paper features photos of these sea-tossed rocks. Some other scientists disagree that these storms will happen. I'll cover that in a coming show.

Right in this new paper, the authors say that what happened in the Eemian period, 130,00 years ago, may not be a good predictor for what is coming for us. But that isn't a good reason to calm down and worry less. At one point in the Eemian, it was only about 1 degree C warmer than today (a level we are approaching rapidly) - and yet sea levels were tens of meters higher than now.

Paul finds two things missing in this paper by Hansen. First: there is no mention of disturbance of the Jet Stream, and all the changes that makes to our weather, seen even now. The link to melting of Arctic sea ice is not part of the calculations. Second, and this is close to Paul Beckwith and the AMEG group (Arctic Methane Emergency Group) -Hansen doesn't factor in methane coming up in the Arctic, as a jolt to warming, and a positive feedback.

A SUMMARY OF PAUL BECKWITH'S 9 PART REVIEW OF THE HANSEN-LED PAPER

If you are looking for my interview with Hansen co-author Isabella Velicogna, please scroll down a few pages in this blog. My review of the Fort McMurray fires, asking what happens if they burn the tar sands operations - follows that.

Paul did a 9-part series of You tube videos on this paper. Here are my notes on that 9-part Beckwith series, with Paul's text and links to each.

PART 1: Two degree Celsius Global Temperature Rise is Highly Dangerous

Published on Jul 23, 2015

"My first of a series of videos examine highlights of Hansen et al., a landmark 66 page paper with 16 authors titled "Ice Melt, Sea Level Rise and Superstorms: Evidence from Paleoclimate Data, Climate Modeling, and Modern Observations that 2 oC Global Warming is Highly Dangerous"

A previous warm period about 130,00 years ago, is the Eemian - sea level 5-9 meters higher than today, and enormous storms, not seen in the Holocene. Temp was up to 1 deg higher - may have been less "we're almost there". But our drivers and rates of change are higher than ever seen in paleologic record.

Key finding is non-linear ice sheet disintegration is happening now. (Paul has looked at doubling period and asks if there could be 7 meter sea level rise by 2070).

The ocean is warming, especially 1-2 kilometers down. In the Arctic and Antarctic this is the grounding level of massive ice shelves. When ice shelves go, it's like removing a cork, which will speed up movement of ice sheets toward the sea.

The vertical ventilation in Antarctica is reducing - ocean stratification.

Another key finding is that increased ice melting decreases the surface temp of ocean. Which could explain the cold blob south of Greenland. That can create a pressure difference (baroclinicity) that can lead to extremely high winds, and thus changes to ocean circulation pattern. The high winds can generate high waves over very large distances. Geologic evidence shows them rolling from southeast to southwest, arriving in the Bahamas, 30 meters high, 20 meters in Bermuda. (30 meters is about 100 feet). These waves are big enough to sink ships, possibly ending ship traffic at that time and place.

Another key finding, during late Emian sea level rose 2-3 meters in a few decades. It's an "enormous catastrophic rise" Paul says.

Another key: in ocean circulation over 500 to a thousands years or more, these natural time frames no longer apply to rates of change today.

In summary 2 degrees C warming is highly dangerous.



BECKWITH VIDEO TWO ON THE HANSEN PAPER

Part 2: Humanity at a Crossroads. Today...

Published on Jul 23, 2015

"In the classic movie "A Christmas Carol" miser Scrooge was visited by 3 ghosts, of past, present and future. Humanity is Scrooge, and Paleoclimate is the past ghost, while extreme weather events increasing in frequency, severity and duration, extensive fires, methane emissions and ocean acidification are the parent ghost. The ghost of the future that will be if we continue our present fossil fuel combustion pathway is very dire..."

If the oceans become more stratified, with less circulation, then the "sink" ability of the ocean to capture our excess CO2 is reduced.

BECKWITH VIDEO THREE ON THE HANSEN PAPER

Part 3: Sea Level 5 to 9 meters Higher Than Now

Published on Jul 23, 2015

"In the last warm interval on Earth (called the Eemian), global temperatures were likely only +0.2 or +0.3 degrees Celsius warmer than today (+1 degrees maximum), and sea level was +5 to +9 meters higher. Are we rapidly heading there NOW?"

BECKWITH VIDEO FOUR ON THE HANSEN PAPER

Part 4: An Ocean Full of 30 meter Tall Waves.

Published on Jul 23, 2015

"Near the end of the previous warm period (Late-Eemian) when the sea level was +5 to +9 meters higher than today, persistent long period long wavelength waves 30 meters high battered the Bahamas coastline. Will we see these massive storm generated waves soon? No ship could survive this..."

PART 5

Part 5: Evidence for Ocean Circulation Disruption

Published on Jul 24, 2015

"North Atlantic Ocean sediment cores from the sea floor provide age information on ocean temperature, ocean circulation and ice sheet destabilization inferred from ice rafted debris (IRD - rocks carried by icebergs then dropped to sea floor when ice melts). Following Hansen et al. I discuss the AMOC (Atlantic Meridional Overturning Circulation) and the SMOC (Southern Meridional Overturning Circulation) changes and connections."

PART 6

Part 6: Climate Simulations for Ice Sheet Melt Water into Oceans

Published on Jul 24, 2015

"I discuss Hansen et al. climate modelling methods and results. Main results show that ice cap melt on Greenland and/or Antarctica injects fresh water into oceans near respective continents causing rapid sea level rise and shuts down AMOC and/or SMOC leading to enormous global climate disruption, including massive storms."

At 10:30 mintues, Beckwith discusses how changing ocean currents can affect storms in the North Atlantic. Winds from N.E. to S.W. can create super storms. If you increase winds speed 10 or 20 percent it can increase storm power up to twice. "Enormous waves across the North Atlantic would eliminate ship traffic" because no ship is built to withstand 30 meter waves (100 feet high).

It sounds like terrible news for the Caribbean, but what does it mean for Europe? or North America?

PART 7

Part 7: Earth Energy Imbalance and Southern Ocean Controls

Published on Jul 24, 2015

"Earth system Energy Imbalance causes warming when more heat is trapped than released. Forcing from orbital changes, albedo changes and greenhouse gas changes are discussed per Hansen et al. The vital role of the Southern Oceans on CO2 and temperature, as well as subsurface ocean temperature and ice sheet destabilization leading to rapid nonlinear sea level rise is also discussed."

The Southern Ocean is the "gateway to the global deep ocean". It also controls S. Ant meltwater rate and global sea level rise.

PART 8

Part 8: Modern Evidence of Abrupt Melt in Greenland and Antarctica and Ocean Changes

Published on Jul 24, 2015

"Modern data on ocean circulation changes in AMOC-Atlantic Meridional Overturning Circulation, and SMOC-Southern MOC are examined. Abrupt changes are occurring today."

Circulation has already changed since the 1980's. Talks about the "Polynyas" which create pools that raise the heat. They have become more rare in Antarctica, saying that heat is staying in the deeper ocean.

Ice core data from Antarc. from ocean sediments show 8 episodes of very large ice flux - largest 14,600 yrs ago, meltwater pulse 1a - 1-3 meters sea level rise per century for several centuries. We have less ice to start with now, but the forcing is much more rapid.

Seasonal sea ice is growing in Antarctica.

At 8:20 minutes Paul discusses the problem of "doubling rate" vs a linear projection as the reason why IPCC projections are always so low, compared to reality.

He describes the regions of Antarctic most at risk.

PART 9

Part 9: Summary: Ice Cap Melt and Sea Level Rise in our Anthropocene

Published on Jul 24, 2015

"With BAU (Business As Usual) humanity faces a very abrupt future of misery; including rapid 5 to 9 meter sea level rise taking out coastal cities around the planet. I analyze findings from the landmark Hansen et al. paper titled "Ice Melt, Sea Level Rise and Superstorms: Evidence from Paleoclimate Data, Climate Modeling, and Modern Observations that 2 degree Celsius Global Warming is Highly Dangerous".

Paul begins by discussing at what point global warming really began - 8,000 years ago, the 1960's or what?

Rapid sea level rise may begin sooners than predicted by mainstream climate science so far. This could be do to changes in ocean circulation, and warming waters reaching the grounding lines for ice shelves in Arctic and Antarctica, leading to non-linear increase in melting and sea level rise, impossible to avoid on our current path.

Greenland, Hansen says, does not slope toward the sea, and so may not melt as fast as Antarctica. Paul disagrees, partly due to loss of sea ice, and so no latent heat/cooling, leading to non-linear melting.

With more melting, stronger winds, and long wave trains, we can expect huge waves on top of higher sea level, as happened before.

6:20 "in real life things are happening faster than in the models"

The 2 degree "safe" guard-rail is not safe at all. It leads to sea level rise of several meters, changes in ocean circulation, slow-down of AMOC etc.

Global temperature change is not the best metric. "It gives a false sense of security", because it hides heat going into the ocean. What is key is the energy imbalance. Hansen says CO2 needs to be reduced to 350 ppm, not just a slash in emissions. Various methods are possible.

According to Hansen we have to reduce emissions by about 6% a year, to reach 350 ppm by 2100. Paul calls it a "landmark paper".

That video series by Paul Beckwith operates like a mini-course in climate change. Of course, Paul has created several videos to teach climate change to all of us. Find his series at paulbeckwith.net, or by searching You tube for "Beckwith".

On radio, we discussed what might be the biggest scientific paper of this decade, if not this century. It's from a team of scientists led by the famous Dr. James Hansen. The title is "Ice melt, sea level rise and superstorms: evidence from paleoclimate data, climate modeling, and modern observations that 2 ?C global warming could be dangerous". I'll be doing more interviews and analysis as we go along. Dr. Hansen agreed to do an interview for Radio Ecoshock, but at this writing, he has not shown up yet.

HANSEN CO-AUTHOR AND ICE EXPERT ISABELLA VELICOGNA

Yes, Isabella Velicogna is a co-author on the new paper led by James Hansen. She's also a power researcher in her own right. Educated in Italy, Isabella has a collection of roles with NASA'S Jet Propulsion Lab, the CIRES Institute at the University of Colorado - and she's an Associate Professor of Earth System Science at the University of California, Irvine.

On Radio Ecoshock, you've heard me talk about the pair of satellites called GRACE. These twins in space can measure changes of gravity in land, sub-surface waters, and ice at the poles. Isabella Veligogna can use that information to "study the mass balance of the Greenland and Antarctic Ice Sheets and glaciers worldwide, in response to climate warming."

That's just part of her expertise, including research on the high Arctic water cycle, and projections of sea level rise due to climate change. All this fits perfectly into the new publication that is rocking the science world. It's a long paper with a long title: "Ice melt, sea level rise and superstorms: evidence from paleoclimate data, climate modeling, and modern observations that 2 oC global warming could be dangerous".





Dr. Isabella Velicogna

I ask many questions about the process of ice melt in Antarctica, rather than the more popularly reported loss of ice in the Arctic. That is because several scientists have told me what happens in Antarctica will determine the long time geography and fate of the world. There is so much ice there, just one glacier like the Totten glacier can raise global mean sea level by over one meter. NASA has already said the melting of the Totten glacier is "unstoppable".

Isabella explains the total ice loss at the South Pole, and the most at-risk areas. Frankly, I got yet another education just talking with her. You can too.

COULD THE TAR SANDS OPERATIONS CATCH FIRE, EXPLODE, OR BURN FOR YEARS?

In the Radio show, I do an off-the-cuff talk with Paul Beckwith on the climate ties to the Fort McMurray fires. I took some heat myself for posting a You tube video, in the early days of the fire, suggesting the tar sands themselves make super fires more dangerous. That's just scientific fact, but some posters called me bad names.

Watch my short controversial You tube video here. Or just listen to the audio here.

Here is a list of the best articles about the fires, in my opinion:

I'll be having meteorologist Jeff Masters on in a future show, helping me to imagine what the Hansen-type superstorms could look like.

BREAKING NEWS!!!! (irony alert)

=================================

Bloomberg reports smoke from the fire complex has reached the tar sands operations of SunCor, just north of Fort McMurray. Already the size of Luxembourg, the fire is expected to double in size in 24 hours. It may burn for months, since only prolonged rain can stop it. The Canadian Bank of Montreal has revised Canada's economic prospects downward, as more tar sands production facilities close. Millions of barrels of oil per day have stopped flowing. As a world-class superfire, this will be Canada's most expensive natural disaster, with expected costs over 7 billion dollars U.S. and counting.

=================================

That sounds exciting doesn't it? I said we must avoid seeing the climate crisis as entertainment. The news knows how to show us striking video, with music that makes us feel part of great events. They know we will flock to the news coverage, and then see their advertising, to buy more products that are part of the problem. It's our human nature to be fascinated with catastrophe, and so climate disaster sells. Even greens become glued to extreme weather porn generated by an unstable atmosphere.

We are also drawn to something new. Here is a new question for you: can the tar sands operations burn, and what happens if they do?

Robert Scribbler writes: "Smoke plume analysis indicates that the northern extent of this monstrous fire is just 3 miles to the south of the nearest tar sands facility."

Now the big blotches of tar sands production lands have been mostly deforested, which is part of their massive environmental damage. So there are fewer trees to burn there. But my question is: can the tar sands lands themselves burn? The industry says the bitumen is too dispersed in sand to burn. But I wonder if anyone knows what happens when such super-heated fire storms arrive. Dr. Michael Flannigan of the University of Alberta told us such hot fires can burn several feet into the ground. What happens when that arrivesin the pits of exposed bitumen? No one really knows.

Plus the tar sands operations have gigantic tailings and wastewater ponds which are loaded with various types of petrochemicals. They have storage tanks full of flammable stuff.

Along those lines, I heard a television interview with a fire chief who worried that a gas storage plant near the fire could explode. If it did, he said, the blast zone would be 14 kilometers, or 8 and a half miles wide. Emergency workers are justifiably terrified it could blow, and this is just one of a thousand reasons why the people evacuated from Fort McMurray won't be going home any time soon. That was at the Nexen site, north east of Fort McMurray.

The Canadian magazine "Macleans" asked this question. In their article "Could the oil sands catch fire" they write:

"A 2004 article in the U.S. National Fire Protection Association Journal offered a list of the potential fire risks faced by Suncor Energy, one of the oil sands’ biggest producers. It included: 'hydrocarbon spill and pressure fires; storage tank fires; vapour cloud explosions; flammable gas fires; runaway exothermic reactions; and coke and sulfur fires.'"

The article quotes Chelsie Klassen, from the Canadian Association of Petroleum Producers saying the toxic tailings ponds are not flammable. I'm not so sure. Maybe we'll find out.

What about the giant extraction and processing facilities? Presumably there are pits the size of cities where the tarry bitumen has been exposed by skimming off up to 75 feet of the soil. If those catch fire, is it possible that like peat fires, they could burn for years? Just consider the amount of carbon this would add to the atmosphere, and the lasting smoke which would pour across Western Canada for how long... years? A decade? Is it possible? We don't know, this situation has never happened before. I hope we don't find out, but we might experience a new kind of fire event in Canada, a kind of fire Fukushima.

Beyond strip-mining bitumen, the other type of extraction, called "in situ", involves sinking pipes and literally melting the ground below, to make the sticky tar more mobile, so it can be pumped to the surface. That requires unbelievable amounts of natural gas, which has often been fracked in Northern Alberta and British Columbia. That fracking, and the transmission of gas releases very potent methane in amounts that can be measured by airplanes or even satellites. So there's lots of greenhouse gases before the extraction process even begins.

Then the gas is burned, with more emissions. There must be gigantic gas storage facilities and feeder pipelines all through that area just north of Fort McMurray. We are talking about land the size of smaller European countries. If the fire reaches all that, the explosions and greenhouse emissions would be off the charts, things not seen before on this planet. What if the tar sands operations catch fire and blow? Maybe it didn't happen, this time. It's a huge risk.

WHAT IT TAKES TO CONVERT GOO TO OIL

Tonight while walking, I met a local citizen who told me the tar sands are a clean source of fuel, because Canada has regulations, while there are no environmental regulations in Middle Eastern countries. He obviously doesn't know the highly polluting energy train required to get sticky bitumen out of the ground, whether you mine it or melt it. Even then, it isn't oil. It's a kind of pre-oil.

That bitumen has to be treated with hydrogen, at very high temperatures, blast furnace temperatures, again using tremendous energy with tremendous emissions, to get a heavy prequel to oil. Transport that oil prequel, using more energy, to specialized refineries that can deal with heavy oil, which is again a more intensive process with more emissions, and you get products like diesel fuel.

That's all there is to it, compared to light oil that can be easily pumped out of the ground in the Middle East, or from the sea-bed off Norway. That is why oil from wells requires about 1 barrel of oil to produce up to100 barrels of oil, while the tar sands require the equivalent of about 1 barrel of oil to produce at best about 5 barrels of fuel. The ratio is so low, that if all we had was tar sands oil, civilization as we know it would collapse. There isn't enough return on energy investment to have all the energy left over that we depend on.

That is why the tar sands oil is among the dirtiest energy sources, from an emissions perspective, of any fuel in the world. Even most Canadians don't know this. The people whose paychecks depend directly on the Alberta energy industry don't want to know. In fact, many react with surprising anger when you tell them. And they can say with a straight face that black is white, that tar sands oil is cleaner than oil from Venezuela or Norway.

As American author Upton Sinclair said: “It is difficult to get a man to understand something, when his salary depends on his not understanding it.”

THEY ALWAYS SAY "WE WILL REBUILD" - EVEN WHEN WE SHOULDN'T

Here the Fort McMurray tragedy becomes another repetition of classic human error. After evey disaster, every politician, local to national, promises "we will rebuild". That's what they said after Hurricane Sandy, or Hurricane Katrina. That's what they always say.

Fort McMurray was already entering a stage of collapse when the fire hit. Rebuilding everything is the bridge to nowhere.

Look, I have family who evacuated from Fort McMurray, with nothing but their car, their kids and their dog. The harsh truth is that many, many people in Fort McMurray were one credit card payment away from utter bankruptcy. Tens of thousands of jobs were lost as expensive oil was crushed by cheap Middle Eastern oil, and cheap fracking oil.

The sad truth is that most Canadians, who used to be great savers, instead became addicted to debt. They built mini-mansions in the northern wilderness at inflated prices. They bought monster pickup trucks for $70,000 dollars, on 8 year payment schemes. They bought off-road vehicles, boats, clothes, the lot, mostly on credit. Because a person with a high school education could make over $100,000 a year, Fort McMurray became a party that could never end. Drug use and drug crime was phenmomenal for the size of the city. It was all ripe for a fall, and it fell.

Countless evacuees are showing up on the news with absolutely nothing, after ten years or more working in the gold mine that was the tar sands. They were on the edge of bankruptcy, with no savings. And now they are climate evacuees who don't know they are climate evacuees. The heart-ache is just beginning. The bill to the taxpayer is just beginning. This will take years to sort out, and some people will never recover. The people of Fort McMurray will fade out of the headlines, perhaps pushed out by the next extreme weather event, or giant storm. But the blow to Alberta and Canada will go on and on.

It's come to the point where trees are now a threat to any city. My own home could be next, or yours. There is practically nowhere that cannot burn out of control. Ask people in Australia, California, or the Himilayas, Indonesia, almost anywhere. I'm sure some cities will try to cut down the forest around them, maybe even limit tree planting within city limits. That just releases more carbon, and reduces the ability of trees to absorb carbon dioxide.

As Paul Beckwith says, we have entered the age of the climate casino. You could be the next climate evacuee. No city is safe, from some sort of climate extreme. Nobody is immune.

THE ONLY SOLUTION

The only solution is to recognize reality and tackle the root of the problem. That means converting away from the fossil fuel-based civilization. That process begins with closing down the worst and most polluting forms of fossil fuels. At the top of that list are two fuels: coal and tar sands.

Coal in Western countries is going bankrupt. It still fuels most of India, China, and much of the developing world. The tar sands could shut down tomorrow, and the oil glut would still continue. We don't need them. Canada must stop promising to rebuild that deadly infrastructure, stop subsidizing the dirtiest oil, and adopt a plan to close down these facilities entirely within five years, if not immediately. That's what it takes.

The alternative is to keep on suffering, if we can keep on at all.

I'm Alex Smith. This is Radio Ecoshock, for the world.

EXTREME ARCTIC FEAR

SUMMARY: Abrupt warming in Arctic could lead to catastrophic consequences says top scientist Dr. Peter Gleick, ICCI Director Pam Pearson, and the founder of Paleoceanography, Dr. James Kennett. Three must-listen interviews.

"What is happening in the Arctic now is unprecedented & possibly catastrophic."

That's the Tweet heard around the world at the end of February. It was picked up by the Independent newspaper in the UK, and many other places in the alternative and climate-savy media. Robert Hunziker did a strong piece about it in CounterPunch called "The Arctic Turns Ugly".

The Tweeter is a world-known scientist. Dr. Peter Gleick is a member of the US National Academy of Science, he's a MacArthur Fellow, and President of the Pacific Institute. He was a guest on Radio Ecoshock in March 2014 (find the blog and links for that audio here).

DR. PETER GLEICK WARNS OF POSSIBLE ARCTIC CATASTROPHE

Why is it warming so much - is it just "El Nino" or is it really climate change? Generally, scientists say El Nino affects the Pacific, but not the Arctic. Most of the strange warming in the Arctic this past winter (with record low sea ice) is due to our heating the atmosphere, and not El Nino.

I ask Peter Gleick, why he is alarmed about this, and is that concern shared by other scientists?



Dr. Peter Gleick

The United Kingdom has practically been buried by storm after record-breaking storm this winter. Peter Gleick thinks abnormal weather is directly connected to big changes in the Arctic. That's the new understanding, led by scientists like Dr. Jennifer Francis of Rutgers University. The Jet Stream has been altered by the fact that there is less temperature difference between the poles and the equatorial zones. The oceans are hotter. The land is hotter, and in some places drier. All these things change the weather.

I worry an abrupt shift in climate could happen, and the corporate media would still bury us in Donald Trump and the Kardashians. Do you think climate silence is a conspiracy by a few major media corporations - or is it possible that all of us are so addicted to fossil fuels, we really don't want to know?

To be honest, I can barely bring myself to read the latest news. Maybe the problems in the Arctic are just too big to comprehend, or just too scary to face? Is it worthwhile to keep fighting, if all we can do is slow down the loss - and the damage, for the next generation?

There is, says Gleick, a big difference between a civilization facing severe challenges as the Earth warms, and a planet where climate changes so far and so fast that civilization cannot cope or adapt. We'll have to make major efforts to adapt to what we have already done. We can't continue to make it worse. So "yes" it is worth keeping up the fight.

Let's say Greenland ice loss doubles or triples, and the Arctic sea ice disappears for most of the year. Gleick agrees nobody knows what would happen. When we change the greenhouse gases in the atmosphere, we are running a giant experiment on the Earth. It's already out of control.

Gleick is a senior scientist, recognized around the world. When he suggests a "catastrophe" might be developing, is that language too extreme? He tells us that again, no one can say for sure, but our current path is taking us to climate changes so extreme it could easily become a catatastrophe.

Find out more about Dr. Peter Gleick, at the Pacific Institute. The web site is pacinst.org. Peter is author of many scientific papers and nine books, many of them reporting on world freshwater resources.

PAM PEARSON - CROSSING THRESHOLDS OF THE CRYOSPHERE

A surprising amount of Planet Earth is frozen. It's been that way for millions of years, all during our life and evolution. Last December, the world's leading experts on this frozen land and sea - warned Earth is heading into irreversible loss in the cryosphere. Nothing short of an ice age can avoid incredible changes that will re-arrange sea levels, cities, and life as we know it. Practically nobody heard them.

Scientists and civil servants who know this danger gathered into a largely volunteer group called the International Cryosphere Climate Initiative, known as ICCI. They've issued a report called "Thresholds and Closing Windows, Risks of Irreversible Cryosphere Climate Change". We are joined by one of the co-ordinators of that report, Pam Pearson, the Director of ICCI. In fact, she founded this network of ice science specialists just as the 2009 Copenhagen climate talks failed.

"Policy makers and the general public alike now largely accept that the Arctic, Antarctica and many mountain regions already have warmed two-three times faster than the rest of the planet. What is less understood, outside the scientific community, is that the very nature of the cryosphere – regions of snow and ice – carries dynamics that once triggered, in some cases cannot be reversed, even with a return to lower temperatures or CO2 levels."

The Cryosphere breaks down into 4 important components, all acting differently on different time scales:

1. Ice sheets (polar land-based ice)

2. Mountain glaciers (retreating everywhere around the world)

3. Permafrost (up to 20% of the Earth's land mass is "permanently" frozen, except it's not. It's thawing.)

4. Arctic and Antarctic sea ice (floating on ice surface, does not add to rising seas, but does increase warming when melting back and exposing darker ocean water to sunlight.)

The report also covers Polar Ocean acidification.

I think the first thing to grasp is that politics and propaganda can't change a simple fact of physics: once the temperature goes over 0 degrees C, or 32 Fahrenheit, water changes state from ice or snow to a liquid. We can't talk our way out of that. The report says:

"Cryosphere climate change is not like air or water pollution, where the impacts remain local and when addressed, allow ecosystems largely to recover. Cryosphere climate change, driven by the physical laws of water’s response to the freezing point, is different. Slow to manifest itself, once triggered it inevitably forces the Earth’s climate system into a new state, one that most scientists believe has not existed for 35–50 million years."

The Arctic has been unbelievably hot this past winter. It rained in the dark of December, and I just read the Arctic February was more like the temperature expected in June.

But the ice-world is not just thawing at the Poles. I remember years ago the famous nature TV star Steve Irwin lamenting that tropical glaciers were disappearing. Now this report says that even if the Paris climate deal is carried out, we can still expect: "Complete loss of most mountain glaciers."

IRREVERSIBLE LOSS OF ICE

The Fifth Assessment of the Intergovernmental Panel on Climate Change, the IPCC, DID say that many aspects of climate change are "largely irreversible on human time scales." But they buried that on page one thousand and thirty three of a fat report that hardly anyone reads!

About two dozen scientists published an open letter in the Guardian newspaper last December, urging more action to protect the cryosphere, at the Paris climate talks.

I found it fascinating that this ICCI report devoted a chapter to acidification of the polar seas. We know oceans become more acidic due to a chemical reaction with the carbon dioxide we keep adding to the atmosphere. But I haven't seen much about this at the Poles. It's happening even worse there, as colder water can absorb more carbon, which becomes carbolic acid. Northern fisheries and all marine life are threatened by this change.

THAWING PERMAFROST

I've done several shows on thawing permafrost. Scientists in Canada, Scandinavia, Russia and Alaska are most interested, but so are the people who live in those lands full-time. Is there a tipping point where once permafrost starts to go, it can fuel it's own further thawing? Apparently so.

The ICCI report says of permafrost thaw: "any carbon release [is] not reversible even with [a] new Ice Age, except on geologic time scales." I found that in a couple of places in the report. Even a new Ice Age may not be able to return Earth to the state known for millions of years! Most scientists say that the next possible date for an ice age, based on the tilt of the Earth's axis, - that ice age will not happen due to the warming gases we have already added to the atmosphere. So count that out.

You can find out more about melting permafrost as a driver to global climate change here.

WHAT ABOUT THE FROZEN METHANE - THE CLATHRATES?

One thing I found missing in this report is the threat of melting of frozen methane on the sea-bed, known as clathrates. Other scientists see clathrates as a likely driver in past extinction events. Why isn't it in this ICCI report? Pam tells us the science about clathrate melting is not yet sure. Some scientists say that for now, the methane released in Arctic waters is likely to be absorbed in the water column, before it reaches the surface and the atmosphere. Others, like Dr. Shahkova, say their research shows methane is already being released in the Arctic, more and more.

The authors of the ICCI report already had four irreversible certainties to report. They didn't want to add the clathrate problem until more finished science is in. Some of their scientists disagreed. It's not settled. See what our next guest, Dr. James Kennett has to say!

ABANDONING OUR COASTAL CITIES - IS THAT "ADAPTING"?

Here is one more paragraph from the stunning introduction to this report "Thresholds and Closing Windows":

"Adaptation to the levels of projected climate-related disruption, particularly sea-level rise that cannot be halted and accelerates over the centuries, simply will not be possible without massive migration and other changes to human centers of population and infrastructure, that will carry enormous economic and not least, historic and cultural costs."

Basically: humans will have to leave their coastal cities behind, and the some of the most fertile near-ocean river estuaries that now support many millions of people.

According to this ICCI report: "The only way fully to avoid these risks is never to let temperatures rise into these risk zones at all." After the climate is broken, and the cryosphere starts it's unstoppable melt, there is no way to "fix" it.

DR. JAMES KENNETT - ABRUPT CLIMATE CHANGE FOUND IN THE PAST

Just 10 years ago, scientists told me melting the world's ice system would take thousands of years. Since then, with the shocking ice loss at both poles, we're not so sure. Abrupt climate change is possible. We're about to explore what can happen within one lifetime - that has already happened in the ancient past.

To find the clues, we dig into the sea bed with a founding expert in the field. Our guest is recognized as the father of that science, called Paleoceanography. He started publishing in the 1960's. He wrote the standard college textbook "Marine Geology", and founded a journal on this subject.



Dr. James Kennett

Dr. James Kennett is Emeritus Professor of Marine Geology and Paleocoeanography, in the Earth Science Department of the University of California, Santa Barbara.

For me, the startling results of this study, published October 2015 in the Journal Paleoceanography, is what could happen in just 50 years, easily within a single lifetime.

The paper name sounds very technical, but don't let that scare you off this interview. Kennett explains things very clearly, and it's one of the most important interviews I've done recently. The title is: "Abrupt termination of Marine Isotope Stage 16 (Termination VII) at 631.5?ka in Santa Barbara Basin, California".

You can read about this Santa Barbara Basin research in this helpful AGU article by Julie Cohen.

We learn in this paper that about 630,000 years ago, there was a relatively rapid shift out of a cold glacier period, to an interglacial period that was a lot warmer. The whole process took about 700 years - BUT it started with an abrupt temperature rise in only 50 years! Kennett tells Julie Cohen:

Of the 13 degree Fahrenheit total change, a shift of 7 to 9 degrees occurred almost immediately right at the beginning.

WHEN YELLOWSTONE BLEW UP

What do catastrophic events in Yellowstone Park have to do with all this? Well first of all, Kennett has studied and written papers on the Yellowstone Caldera, the giant hole in the ground blown out in an ancient explosion. He told science journalist Julie Cohen:

Our tests showed that this particular ash was ejected from the Yellowstone volcanic caldera in Wyoming, which has exactly the same fingerprint. This huge caldera formed about 630,000 years ago, with most of the enormous volume of ash blown to the east. However, this eruption was so explosive that the ash reached the Santa Barbara Basin, forming a layer one to two inches thick. The discovery of this ash helped with dating the core.

Kennett tells Radio Ecoshock listeners there were in fact two gigantic blasts at Yellowstone, about 200 years apart. The first was followed by a cloud that rolled around the Northern Hemisphere, blocking out the summer sun, and creating an instant cooling, similar to a "nuclear winter". The second created an even longer constant winter.

ANOTHER SCIENTIST WORRIED ABOUT CLATHRATES AND ABRUPT CLIMATE CHANGE

Some of our listeners are deeply worried about much more global warming methane being released in our current climate shift. This paper talks about: "repeated discharges of methane from methane hydrates associated with both ocean warming and low sea level." Did that methane erupt from the West Coast of North America, or from the Arctic? Kennett says more methane has been measured all down the Canadian and American West Coast in recent years, bubbling up from the sea floor. Hotter oceans are already starting the first signs of clathrate melting. It's happening off the U.S. East Coast too.

This seasoned scientist is deeply concerned about the potential super warming effect of methane releases, as the oceans warm. He's not shy to tell us that, and you should listen. Dr. Kennett suggests that melting clathrates likely triggered the rapid 50 year warming found about 630,000 years ago. But we do not know for certain yet.

This paper did not speculate on a comparison of this 50-year shift a few hundred thousand years ago, and human-induced warming today. But personally, I wonder if we will see a similar deglaciation within a single human lifetime. Have we already entered this process?

I wonder what climate modellers like David Archer will think, after his book "The Long Thaw". Is there disagreement about how fast deglaciation can take place? Yes and no, says Kennett. Everyone who studies ice knows it can take hundreds to thousands of years for a giant glacier like the one covering Greenland to melt. On the other hand, he tells us, there is a big scientific consensus that quite rapid temperature changes have taken place many times in the past. It's both.

After the call, Jim told me that their research team wants to return to the Santa Barbara Basin to drill even deeper cores. These would tell us a lot about the history of Earth's climate and life, including methane releases, going back 1.2 million years. However, there is a lot of oil and gas drilling in that same basin, plus a very environmentally concerned community in California. So far, the scientists have not received permission to go back and open up this critical chapter in Earth's records.

Dr. James Kennett has published hundreds of papers, starting in 1962 right up to the present.

EARTH NOW WARMING FIFTY TIME FASTER

Here's an important article in the UK Guardian newspaper "Earth now warming 50X faster than coming out of last ice age".

That article says:

"What humans are in the process of doing to the climate makes the transition out of the last ice age look like a casual stroll through the park. We’re already warming the Earth about 20 times faster than during the ice age transition, and over the next century that rate could increase to 50 times faster or more. We’re in the process of destabilizing the global climate far more quickly than happens even in some of the most severe natural climate change events."

* methane and melting permafrost in Russia

* record extreme heat in Spain, Portugal and Italy

* will the California drought last 30 years? (and is it time to get out)

* Australians lose billions with heat waves (even indoor workers affected)

* Canadian scientists protest government muzzling

* Arctic sea ice at new record low for May

* Obama approves Shell Arctic drilling

* even more ice loss in Antarctica then we knew.

Or listen on Soundcloud right now!



From Pole to Pole, and around the world, climate news is streaming in, and it's not good. We are crashing into the age of global warming.

Here to help us is one of our favorite guests, scientist Paul Beckwith. Paul has two Masters degrees, and is currently working on his PHD in climate science at the University of Ottawa in Canada.

I began this show by saying: "Paul there's so much hot climate news, it's very hard to keep up. I keep expecting somebody like CNN will start the first 24/7 climate news station. That's the level of coverage we need now, don't you think?"

That turned out to be too true. Hardly had we hung up the phone last Friday, that news poured in about more than a dozen killed by extreme flooding in Oklahoma and Texas. Eleven inches of rain fell in the Houston area in 24 hours. Even concrete bridges were knocked out of the way by the raging flood waters.

As Scientific American reported, "Climate Change may have souped up the record-breaking Texas deluge." May have? The United Nations IPCC and many other climate scientists released papers on the advent of extreme weather now that the climate system is breaking down. Extreme rainfall events have been happening around the world. We know the role that increased water vapor in a hotter world plays, and we know the heated oceans play a part too. It's not a secret.

Maybe it's still a secret in Texas and Oklahoma, who keep voting in climate deniers to Congress, like Senator James Inhofe. I have to wonder what it will take to get the average American to wake up and stop voting for people who stop action to save us from even worse climatic events.

Also on the weekend, the supreme heat wave hitting India. It's especially bad in the Southern Indian states, where temperatures hit 48 degrees, and then flirted with 50 degrees C in some places (188-120 degrees Fahrenheit). More than a thousand died. In our interview, Paul Beckwith tells us why babies and seniors tend to die first.

The Indian government advised people to stay inside. Let me tell you, I've been to India, and to Southern India. Millions of people must work every day, or begin the process of starvation for their families. Or course they are going to work in the heat. They must. And many die. Air-conditioning? Don't forget at least 200 million people in India don't have any access to electricity. People in developing countries die because of our carbon-rich lifestyles. It makes me angry.

Anyway, let's go through just some of the top climate stories, as we move around the globe, starting with two very disturbing records. First this.

RECORD LEVELS FOR CO2

"New Records For Atmospheric CO2

"CO2 averaged 404.11 parts per million the week beginning May 3, a new weekly record.

Since we are now passing the annual spring peak, this record will probably stand until next spring. The week beginning May 10 averaged just under 404. The reading of 404.54 on May 16 set a new single-day record.
"

My comment: It's no big surprise. This whole civilization is based on transferring fossil fuels from underground into gases in the sky. That's what we do...expect to read this story every year.

THE FIRST QUARTER OF 2015 MARKS A NEW RECORD FOR WORLD HEAT

"The first quarter of 2015, a transcendental for the fight against climate change year, has set a new world record high temperatures in the recent history of the Earth.

Data from the National Atmospheric Administration (NOAA) indicate that in March recorded the highest temperature for this time of year since 136 years ago were initiated record, surpassing the previous record, 2010, at 0.05 ° C. The first quarter of 2015 was the warmest period of history in the middle of the land and ocean surfaces in the world, at 0.82 ° C above the average of the twentieth century, surpassing the previous record-from 2002 to 0, 05 ° C.

The average land surface temperature was also overall record for the January-March period. Most of Europe, Asia, South America, East Africa and western North America have had an onset of warmer than normal year, according to the official news agency of the United States.

Regarding the data of the surface of the oceans, last quarter marked the third highest level in the period of 136 years of record, 0.53 ° C above average.
"

Get another take on this story here. Maybe every year won't break the records, but most will.

Let's go to the regional view, starting with this story out of Russia.

CARBON TIME-BOMB IN SIBERIA THREATENS CATASTROPHIC CLIMATE CHANGE

"A DEVASTATING and sudden acceleration of climate change which is currently being sparked could result in 'awful consequences', a leading scientist has warned.

"Climate change expert Professor Sergey Kirpotin, [in Tomsk] 51 said this could result in 'awful' consequences.

'Bogs are extremely important for humanity. They function as a sort of natural freezer as they don't let the carbon build up in the atmosphere,' he told The Siberian Times.

'However, the permafrost in northern areas of western Siberia has started melting. As the permafrost thaws, it creates new lakes and old ones get bigger.

"All the organics trapped in permafrost start decomposing rather quickly.

"Obviously, a lot of greenhouse gases, such as carbon dioxide and methane, are released into the atmosphere.

"Methane is a greenhouse gas 30 times more potent than carbon dioxide.'
"

EXTREME RECORD-BREAKING TEMPERATURES IN SPAIN (and Portugal, Sicily)

Here's a headline from one of my favorite weather guys, and repeat Radio Ecoshock guest, Dr. Jeff Masters of the Weather Underground:

"Jeff Masters: extreme, record-breaking temperatures in Spain

All-Time May Heat Record for Europe Falls For the 2nd Time This Month

by Jeff Masters, wunderblog, May 14, 2015

An extreme May heat wave unprecedented in European recorded history has invaded Spain and Portugal, bringing the hottest May temperatures ever recorded on the continent. According to the Spanish meteorological agency, AEMET, at least four stations in the Valencian Community of eastern Spain hit temperatures today in excess of the previous European May heat record set just eight days ago -- a 41.9 °C (107.4 °F) reading at Catenanuova, Sicily (Italy) on May 6. Today's European record-breaking May temperatures in Spain included:

Carcaixent: 42.9 °C (109.2 °F)

Xativa: 42.7 °C (108.9 °F)

Algemesi: 42.6 °C (108.7 °F)

Valencia: 42.6 °C (108.7 °F)

Many stations in Spain's Valencian community went above their June records, and were near their all-time records for any month. The record set at Valencia Airport today was 6.6 °C (11.9 °F) above the previous highest May temperature, was 4.4 °C (7.9 °F) higher than the record for June, and was the 3rd hottest temperature since records began in 1869 for any month!

This week's heat wave began yesterday, when hot air from North Africa flowed northwards over Spain and Portugal, setting all-time May heat records at Madrid, Sevilla, Cordoba, Ciudad Real, Granada, and many other cities. Portugal beat its all-time May heat record with a 40.0 °C (104.0 °F) reading at Beja EMA (old record: 39.5 °C, 103.1 °F, at Regua on May 28, 2001). The most remarkable record yesterday, however, was from the Canary Islands to the southwest of Spain, where Lanzarote Airport hit 42.6 °C (108.7 °F), breaking its old record for the entire month of May by 6 °C (10.8 °F)! The old record was 36.6 °C (97.9 °F) on May 24, 1986.
"

NOAA: 90% CHANCE OF EL NINO

The last big El Nino we experienced caused new records in heat, during the winter of 1997/98. That was the year Indonesian peat fires turned that country into one of the world's biggest sources of greenhouse gas emissions. The smoke covered most of southeast Asia. What will burn down this time?

Here is how our recent guest Robert Marston Fanney described it in Robert Scribbler's Blog:

"Well, it’s official. According to NOAA’s May 14 update, we are now looking at a 90 percent chance that El Nino conditions prevail through Northern Hemisphere Summer and a greater than 80 percent chance El Nino will last throughout all of 2015..."

RELATED: CARBON EMISSIONS INCREASE RISK OF U.S. MEGADROUGHTS.

California drought continues despite weak El Nino conditions. NASA says on our current carbon course, the whole US Southwest will experience a drought like the 1930's dustbowl, but lasting for 30 or 35 years - a whole generation. That will happen this century they say. "Carbon emissions could dramatically increase risk of U.S. megadroughts" says NASA.

ARCTIC SEA ICE AT HISTORIC LOW

This from the Arctic News blog.

"THURSDAY, MAY 21, 2015

Arctic Sea Ice At Historic Low

On May 20, 2015, Arctic sea ice extent was only 12.425 million square km, a record low for the time of the year since satellite measurements began in 1979.
"

Our guest Paul Beckwith explains it takes 80 calories (a measure of heat energy) to melt 1 gram of ice. When the ice is gone, it takes just 1 calorie to raise the temperature of water 1 degree. Theoretically, the same 80 calories of heat falling on ocean instead of ice could raise the surface temperature by 80 degrees! (It doesn't because there is mixing with cooler water below - but this shows the huge difference between having ice in the Arctic and not.

EXTREME HEAT POSES A BILLION-DOLLAR THREAT TO AUSTRALIA'S ECONOMY

I'll bet the cost is far higher, if you include loss of forests, the costs of fighting fires, the toll on farm animals and crops, etc. The key insight to this article is that extreme heat doesn't just affect outside workers. Even people who work in air-conditioned offices lose productivity. Why? Because humans don't sleep as well during hot nights.

"May 4 2015

Extreme heat poses a billion-dollar threat to Australia’s economy

When heat waves hit in summer, do you have trouble sleeping? And the next day, even though you are working in air-conditioning, are you a bit slower, your judgement a bit off, or your patience a bit frayed?

In a paper published today in Nature Climate Change, we and colleagues show that heat stress probably cost the Australian economy nearly A$7 billion in 2013-2014 through productivity losses such as those we’ve mentioned above.

That bodes ill for the future, with heatwaves forecast to get hotter and more common thanks to climate change. While we should continue to attempt to mitigate climate change, we need to take steps to adapt.

One of our most surprising findings is that you don’t have to work outside to feel the heat. Although outdoor workers report greater levels of productivity losses from heat, indoor workers aren’t immune. Poor sleep is one possible explanation.

COLD WEATHER IS MUCH DEADLIER THAN EXTREME HEAT, STUDY SAYS

Here on Radio Ecoshock, we like to follow the truth, whether it is convenient to theories or not. So far, the greater number of deaths are still caused by cold. But that ratio will change, says Paul Beckwith, as the coldest parts of Earth appear to be warming much faster than the global average.

Just look at Alaska this past winter. It was often warmer there than in New England. We've just heard from Jonathan Mingle the same is true in the Himalayas, often called the world' Third Pole. And I've reported on news that Antarctica is melting more rapidly that we thought (more on that below).

"Cold weather is much deadlier than extreme heat, study says

Extreme weather gets more attention, but moderately cold weather is most deadly by far, a study says, analyzing deaths in 13 countries.

By KAREN KAPLAN

Extreme weather gets more attention, but moderately cold weather is most deadly by far, a study says

In the U.S., 84% of days are colder than the 'optimum,' least-deadly temperature. Extreme heat waves like the one that killed more than 70,000 Europeans in 2003 may be the most visible examples of deadly weather, but cold days actually cause more deaths than hot ones, a new study says.

After examining more than 74 million deaths that occurred in 13 countries from 1985 to 2012, researchers calculated that 7.3% of them could be attributed to cold weather and 0.4% to hot weather.

In another counterintuitive finding, extreme weather — either hot or cold — was responsible for only 11% of the weather-related deaths, according to the study published Thursday in the journal Lancet.

'Heat stroke on hot days and hypothermia on cold days only account for small proportions of excess deaths,' the international research team wrote.

The researchers collected daily data on weather conditions, air pollution and deaths from 384 cities around the world. For each city, they calculated the temperature at which deaths were least likely to occur. All other days were compared to days with this 'optimum' temperature.

With the bulk of the days in all areas being below the ideal temperature, days rated cold but not extremely cold were blamed for the most deaths — 6.7% during the study period.

Extreme cold was responsible for about 10% of all deaths on cold days. However, extreme heat was responsible for about half of all deaths on hot days.

Although the study included data from a range of nations — Australia, Canada, China, Italy, Japan, South Korea, Spain, Taiwan, Thailand and Britain were also included — no countries from the Middle East or Africa were represented. That means the results don’t necessarily apply everywhere.

PROTESTS in Seattle re SHELL ARCTIC DRILLING

Paul and I discuss the paradox of US President Barack Obama saying that climate change is an extreme threat to the nation's security - and then approving drilling in the Arctic by Shell! What the world does not need is more fossil fuels, especially in the fragile Arctic ecosystem.

Shell has their giant platform in the Seattle harbor. Scads of Kayakers turned out to surround the rig in protest.



Photo credit: Daniella Beccaria/seattlepi.com via AP

Shell says their drilling is perfectly safe, even though (a) their last attempt ended in a dangerous failure when their rig broke down and had to be towed back and (b) there is no reliable secondary drilling rig to try to stop a blowout, like the BP giant spill in the Gulf of Mexico. And remember that the Arctic also lacks the warm-water bacteria the helped eat up some of the BP oil. What spills in the Arctic stays in the Arctic, possibly for thousands of years.

Paul wonders if Obama isn't picking his battles carefully. Perhaps it will take one spill or breakdown in the Arctic to bring the public call for banning all drilling. One allowed might stop thousands of planned rigs invading the Arctic in search of more fossil fuels we cannot afford to burn.

YET ANOTHER ANTARCTIC ICE MASS DESTABILIZED

A few weeks ago I tried to wrap up all the Antarctic news with Dr. Roland C. Warner, the Tasmanian scientist. As I said at the beginning of this post, new and bad climate news just never ends. NASA now announces they've discovered another ice shelf that passed a tipping point of no return in 2009. We're just finding out about that one.

"Yet another Antarctic ice mass is becoming destabilized, scientists report

By Chris Mooney May 22

The troubling news continues this week for the Antarctic peninsula region, which juts out from the icy continent.

Last week, scientists documented threats to the Larsen C and the remainder of the Larsen B ice shelf (most of which collapsed in 2002). The remnant of Larsen B, NASA researchers said, may not last past 2020. And as for Larsen C, the Scotland-sized ice shelf could also be at potentially 'imminent risk' due to a rift across its mass that is growing in size (though it appears more stable than the remainder of Larsen B).

And the staccato of May melt news isn’t over, it seems. Thursday in Science, researchers from the University of Bristol in Britain, along with researchers from Germany, France and the Netherlands, reported on the retreat of a suite of glaciers farther south from Larsen B and C along the Bellingshausen Sea, in a region known as the Southern Antarctic Peninsula.

Using satellite based and gravity measurements, the research team found that 'a major portion of the region has, since 2009, destabilized' and accounts for 'a major fraction of Antarctica’s contribution to rising sea level.'

The likely cause of the change, they say, is warmer waters reaching the base of mostly submerged ice shelves that hold back larger glaciers — melting them from below.
"

Chris Mooney does great work on climate reporting. Here is another verion of that same story.

"Glaciers Are Crumbling in Southern Antarctica Faster Than Previously Thought

Victor Luckerson @VLuck

Previously stable glaciers have been melting rapidly since 2009

Multiple large glaciers that were previously not thought to be in danger of melting have been crumbling since 2009, according to a new study published in Science. Researchers have discovered that glaciers on the southern Antarctic Peninsula’s coastline have been steadily thinning over the past several years, with some dwindling by as much as 13 feet per year. The glaciers had not shrunk significantly before 2009.

The rate of melting makes the region 'the second most important contributor to sea level rise in Antarctica,'lead study author Bret Wouters told NBC News. Overall, 80 trillion gallons of water were added to ocean by the Southern Antarctic Peninsula between 2009 and 2014. Continued melting could raise sea levels by another 14 inches.
"

So Antarctica is into "unstoppable" melting. Greenland is pouring ice water into the sea at terrific rates. How far is sea level really going to rise? I recall a few months ago Paul Beckwith put out a You tube video asking if it's possible the world might experience 7 meters (!!) of sea level rise by 2070. That's 22 feet.

At the time I really didn't get it. In this interview, Paul explains his methods and reasoning, and now I wonder if he isn't right. We know for sure that scientists who take a linear view are kidding themselves and everyone else. If we say there is 3 centimeters of sea level rise now, and then extend that to the rest of the century, it looks like a meter of sea level rise by 2100. That's what the IPCC has said.

But once you find out that melting is doubling every few years, that's all nonsense. We'll get a lot more than that! Check out how Paul explains it, in this interview. Or watch Paul's explanation in this You tube video.

CANADIAN SCIENTISTS PROTEST MUZZLING BY THE GOVERNMENT

As I've said before on Radio Ecoshock, if I want to get a quote or explanation of climate research by Canadian government scientists, I have to submit my questions in advance. That request is sent to the Office of the Prime Minister, where junior know-nothings will tell the scientist what to say - a few weeks after the news has passed.

Now Prime Minister Stephen Harper has taken his religious fundamentalism, and his love for the Tar Sands, much further. It's not just climate scientists who are muzzled, but all sorts of people, including biologists and more. Research paid for by the Canadian tax payer is hidden away, made secret. It's something Stalin would do.

In the past two weeks there have been multiple demonstrations by government scientists and workers demanding the right of free speech. It's easy. Just as the American scientists do (after the bravery of Dr. James Hansen) - the scientist merely has to say they are speaking for themselves, and not the Canadian government.

It's been sad to see scientists in their lab coats out with signs, demanding basic human rights. Shame on the government of Stephen Harper. This is an election year. A big change is needed, because Canada has joined the likes of Saudi Arabia in trying to tear down and weaken any effort to forestall the worst of climate change. Until recently, Canada did not even have a plan to reduce emissions. We love the Tar Sands! Who cares if people in India die of heat, if Texans are flooded out, if Canadian forests are ravaged by out-of-control insects. Money drives Canada.

THE SCIENCE BEHIND THE NEWS

Throughout this whole interview, we get more than snapshots of a planet in trouble. Paul gives us a lot of the reasons behind things, explanations of the way the Earth systems really work. It's an education - and that's no surprise because Paul gives lectures at the University of Ottawa. He's a teacher, a communicator, and a research. It's a rare mix.

Paul has two Masters degrees, and is working on his PHD in climate science. He's tasked himself with the specific project of investigating whether a rapid shift in our climate is possible, what would drive that, and what are the signs.

We had record heat here on Canada's West Coast last week. We're getting the hottest of summer weather in the Middle of May. Is this it? Given all we've talked about, could we be going into a shift in the global climate regime, the one Paul has been researching?

NEXT WEEK: EXTREME MEDICINE FOR AN EXTREME CLIMATE DISEASE

I've given you a lot of bad news this week. Next week, we'll talk about what we need to do about it.

Next week we'll talk about the Climate Pledge - a call for a mass mobilization and a change as great as America's sudden shift in 1942, to fight the Axis powers. The President told the car makers to stop making cars. Everyone, from housemakers to farmers were called to support the war effort. Over 40% of U.S. produce was grown locally, in Victory Gardens.

Now that President Barack Obama has admitted climate disruption is a much greater threat than terrorism, it's way past time to act.

Melting Antarctica Will Shake the World

SUMMARY: New science on melting Antarctica. From Tasmania, polar expert Dr. Roland C. Warner. Then the return of Marjory Wildcraft, with more tips on growing your own groceries. Radio Ecoshock 150415

This week on Radio Ecoshock, we're going to the end of the Earth. It's a feature length interview about new science that shows Antarctica is melting. I guarantee you will read headlines, and see amazing video news, from the science you'll hear this week on Radio Ecoshock. For one thing, sea levels will rise around the planet, for centuries, reshaping the coastlines and civilization.

Then we'll finish up with the return of Marjory Wildcraft, with more tips on growing your own groceries. It's all food for thought and action.

I'm Alex Smith. The journey begins.

DISCOVERIES ON ANTARCTICA: A SCIENCE UPDATE WITH DR. ROLAND WARNER

There's a lot of action in Antarctica - and that can bring changes all over the world. Here to discuss recent science is Dr. Roland C. Warner. He is a researcher with the Antarctic Climate and Ecosystems Cooperative Research Centre at the University of Tasmania. Tasmania is the closest Australian state to Antarctica.













In a shocking bit of news, Antarctica just experienced the two hottest days ever recorded there, namely 63.5°F or 17.5 C at the Argentinian Esperanza Base on Antarctic Peninsula. I've heard that was warmer than the temperature in Britain on the same day in late March.

Dr. Warner says it's not that surprising, because there is no doubt Antarctica is warming over-all, along with the rest of the planet. This one-day event doesn't mean much. A previous record was set in 1961. It takes a few thousand days to be "climate change."

According to the British Antarctic Survey on Warming in the Antarctic Peninsula over the past 50 years: that polar continent warmed by 5 degrees Fahrenheit ( 2.8 degrees Celsius), since 1950. In the interview Warner may have said 5 degrees C. but he meant 5 degrees Fahrenheit. Even 5 degrees F. makes this arm of Antarctica pointing toward South America one of the fastest warming parts of the whole planet.

That shows up in giant ice shelves cracking off West Antarctica, like the Larsen B. ice shelf that disintegrated in February 2002. The whole of West Antarctica is losing mass, as shown by the NASA Grace satellites that can measure mass from space. That means it's melting, and eventually several meters of sea level rise will pour out of that part of the continent.

3 KIND OF ICE, ONE KIND OF SEA LEVEL RISE

But hold on, we have to distinguish between three types of ice around the poles. They are:

* sea ice (the surface of the ocean freezes)

* ice shelves (permanently frozen water, over the sea, but anchored to the land)

* glaciers (ice based on land)

As Dr. Warner explains, we know since the famous bath-tub experiment by the ancient Greek scientist Archimedes, water levels will not rise when ice in water melts. That is why your drink does not overflow when the ice cubes in it melt: the same mass of water was already displaced by the ice.

So disappearing sea ice in the Arctic, or collapsing ice shelves in the Antarctic, do not directly add to sea level rise. However, Roland tells us, the ice shelves can retard the flow of glaciers into the sea, and speed up glacier melt when they disappear. So ice shelf collapse can indirectly add to sea level rise. There's lots of science on this.

Secondly, we've been talking about West Antarctica. The biggest portion of the Antarctic continent is "East Antarctica". (There's no point in talking about North or South Antarctica, since everywhere is more or less "North" there.) As recently as five years ago, I can remember reading that East Antarctica would not be a major factor in sea level rise in this century. Not much was happening there, it was said, and in fact some areas were getting colder, not warmer.

That's all been stood on it's head with new science. Last May I did a program on NASA's revelations that East Antarctica was also losing ice mass. Find the blog entry, and that program here.

Our guest Roland Warner is a co-author of a new study that shows massive ice loss from another giant of East Antarctica, the Totten Glacier.



The title of that new science is "Ocean access to a cavity beneath Totten Glacier in East Antarctica". The Totten is the largest glacier in East Antarctica. At 540,000 square kilometers, it's size is simply mind-boggling. For North American listeners, the Totten drains an area more than twice the size of all the Great Lakes put together. Aussies would say it's more than twice the size of the Australian State of Victoria.

Seventy billion tons of ice flows out of the Totten Glacier, into the ocean, every year. That's about the flow rate of Niagara Falls, and it is expected to increase. Why? Because, and this is the crux of the new paper, scientists have discovered deep channels where warmer water can flow right under the glacier. "Warmer" water isn't terribly warm, but it contains enough extra energy to melt the glacier from below.

GROUNDING LINES AND "UNSTOPPABLE" ICE LOSS

That takes us to another key concept going the rounds with experts. It's the "grounding line". My understanding is that's the point where the glacier reaches the sea and floats on top of it. But also: the geography below the glacier will determine what, if anything, will retard the flow of all that ice into the sea. The problem, according to NASA scientists, in West Antarctica, they haven't found any under-glacier mountain or ridge to stop glaciers there from pouring into the sea. That means that really big sea level rise is coming, and again according to NASA, the progress of West Antarctic ice into the sea is now "unstoppable".

A large Antarctic contribution to sea level rise will happen even if we cut all carbon emissions tomorrow. We have crossed that tipping point. That is why Antarctica will shake the world.

Please listen to this interview to get the real science, from a real scientist (which I'm not).

TWO STRANGE TWISTS TO THE ANTARCTIC STORY

We also talked about two strange twists to this story. I encountered the first from comments made by scientist Laurie Padman, a co-author of another paper titled "Volume loss from Antarctic ice shelves is accelerating." Here's the twist: as more glaciers lose mass in Antarctica (adding to global sea level rise) the sea levels around Antarctica, and Greenland, may actually go DOWN.

Why? Because water is attracted to mass, to heavy things, by gravity. If these polar continents lose a mile or more of ice from their land surface, there will be less mass, and so some of the water now attracted to those polar land masses will dissipate, and go elsewhere.

The kicker is that scientists think the extra (from rising seas AND from loss of polar mass) will show up in places like New England. New England sea levels may go up as much as 25% more than other place in the world. Ditto Japan.

The second twist is that Antarctica may actually see snow pile up higher, especially in East Antarctica, due to climate change. A generally warmer world holds more moisture in the atmosphere. That has to come down, and where it's cold, if falls as snow.

The projected increased snow in Antarctica is still rather an unknown. In our interview, Roland Warner said it would take another year of observations to "make it clear whether the acceleration in loss from Antarctic grounded ice sheet was a trend – disentangling the effect of variability in snowfall." In a follow-up email, he meant to say "several more years" and perhaps even another decade of observations. His comments are based on the paper “Limits in detecting acceleration of ice sheet mass loss due to climate variability”, B. Wouters, J. L. Bamber, M. R. van den Broeke, J. T. M. Lenaerts and I. Sasgen, Nature Geoscience 6, 613–616 (2013) doi:10.1038/ngeo1874 Find the abstract and illustrations for that paper here.

MUCH OF ANTARCTICA IS BELOW SEA LEVEL!

We talk about the real geography of Antarctica. Warner says if all the ice were gone, we could sail right through part of Antarctica, going from the Atlantic to the Pacific Ocean without going around Cape Horn at the tip of South America.

As Roland told me in email: "the fact that the region behind the floating part of the Totten has a large region with bedrock below sea-level is important for the potential sea level rise. This was reported in Nature in 2011: Young, D. A., et al. (2011), A dynamic early East Antarctic Ice Sheet suggested by ice covered fjord landscapes, Nature, 474(7349), 72–75, doi:10.1038/nature10114. Find the abstract for that paper here, or download a .pdf of that paper here.

It's not easy trying to map our this continent, below a mile or more of ice! Scientists are still working on it, and some parts of Antarctica are still unknown, the last frontier some would say.

We also talk about the lack of scientific consensus on how much sea level will rise by the year 2100. The Intergovernmental Panel on Climate Change (IPCC) has been very, very conservative, suggesting one meter by the end of this century. Others say we will get one meter of sea level rise from Antarctica alone. Some scientists suggest several meters of sea level rise (more than 10 feet) is possible. We don't know yet.

Hanging in the balance are many of the world's largest cities, which would be partially submerged. Several countries in the South Pacific are almost guaranteed to disappear. Deltas supporting millions, as in Bangladesh for example, will fill with salt water, ending agriculture there. This may be the biggest question of climate change.

MAKING THIS UPDATE

I had a little difficulty finding a scientist with wide interests in Antarctica willing to give us this update. Roland Warner was brave to take it on, with an eye to keeping us in the research loop - because this is really important news for all of us, even though it takes place far away. The coasts of the world will be re-arranged, no matter where our cities are, because of melting in Antarctica.

Roland is a research scientist for the government-funded Antarctic Climate and Ecosystems Cooperative Research Centre. That's located in Tasmania. I thought the island of Tasmania was the part of Australia closest to Antarctica, but Warner tells me Australia claims islands that are closer still. In fact, Australia has laid claim to 42% of Antarctica. Many countries claim parts of the Continent, but all those are currently on hold, under the Antarctic Treaty established in the 1950's.

Warner has flown many times in an old World-War Two vintage DC3 airplane over Antarctica, as they make painstaking maps and measurements. The propeller driven planes can fly at the slow speeds needed to operate the instruments. It's many hours out and back, with no civilization below. Warner was also aboard the Australian ice breaker Aurora Australis when it made the closest approach ever to the Totten Glacier front, where it drops giant chunks of ice into the sea.

He's been part of a research venture called ICECAP - Investigating Cryospheric Evolution through Collaborative Aerogeophysical Profiling. Apparently ICECAP can also stand for Investigating Cryospheric Evolution of the Central Antarctic Plate.

Any way you take it, events on Antarctica will re-shape our world. We were lucky to get extended time from Dr. Warner. I also appreciate his help in educating me in preparation for this interview. Any errors found in this blog are my own, and not those by Roland Warner.

MORE ON GROWING YOUR OWN GROCERIES

Last week we featured Marjory Wildcraft, author of the wildly successful DVD series called "Grow Your Own Groceries". She organized a super-summit of small-scale growers, home gardeners and pepper gardeners - all free last week. It was the "Home Grown Food Summit" with over 30 presenters. Over 100,000 people tuned in for that!

That shows the amazing growth of people who want to grow their own food for a variety of reasons including:

* knowing factory foods are bad for your health (pesticides, toxics, fats, sugars)

* knowing factory farming is bad for the environment (global warming, soil loss, abuse of animals, GMOs)

* knowing the supermarket food system is fragile, and may fail without much warning

* experiencing the high cost of food, and looking for cheaper alternatives

That's just the short list. Did I mention crops failing due to climate change and extreme weather?

So I asked Marjory to come back, with more tips we can all use to grow food. In this interview, we assume you know why to do it. Now we get down to how to do it.

We had Sylvia Bernstein, one of the original writers about aquaponics, on our June 2013 Radio Ecoshock Show. Find the blog for that interview here. You can download or listen to that interview with Sylvia here. She's fabulous. But when I watched some serious You tube videos about it, aquaponics seems pretty tricky and demanding. It can be tricky keeping fish alive.

There's no doubt that aquaponics can provide some super veggies, really lush crops. But I worry it will require too much energy to keep the fish warm enough in the winters in northern states or Canada. Yet the people who have a mind to manage an aquaponics system have a lot of top quality food to show for it. It's up to you.

We all know gardening can help seniors maintain their mental and physical health much longer. But eventually we may not be able to handle the heavy work. We talk a bit about how can we set up a garden to keep going with very little effort. Thinks like raised beds can help those who have trouble bending over, for example. In fact busy working people need the same thing. We can't cover it all in a short interview. Check out Marjory's DVD course for her tips to save time and effort.

You know it's strange. You start following your heart into something, as Marjory did with her transition from a financial planner to personal food growing, (which I could also call personal liberty.) Then she teaches, communicates, and suddenly, Marjory Wildcraft has become a one-woman movement on her own. Of course, as we discuss, she's connected to a world-wide collection of home-growers, all sharing tips, all educating one another.
