SHOW SUMMARY
We talk with the scientist with the biggest climate news of 2014. Dr. Steve Sherwood in Australia made a breakthrough on the future of clouds. It's not good news: we are headed over the climate cliff to a world at least 4 degrees Centigrade hotter.
But sometimes the doom talk goes too far. Nuclear Engineer Arnie Gundersen says the West Coast is not highly radioactive from Fukushima, no matter what Net newbies tell you.
Are you concerned about all the pesticides and other chemicals getting into your body? Bruce Lourie has a new book out about toxic stuff getting into us, how to get it out, and which detox methods really work.
While big national governments are failing miserably on climate change, local city governments are trying to make themselves more sustainable. Are we headed in the right direction? Daniel Kammen has advised the White House and the World Bank. He's got some advice for all of us, here on Radio Ecoshock.
Four voices from a turbulent world. You'll find lots of links to follow up below. Let's get started.

FEWER CLOUDS = HOTTER WORLD - SCIENTIST STEVE SHERWOOD
Dr. Steve Sherwood, University of New South Wales, Australia.
We may double the amount of greenhouse gases in the atmosphere by 2100. More likely we'll triple them. Scientists have been divided about what that means. Will the temperature go up a liveable 1 or 2 degrees above pre-industrial times or will it be 4 degrees or beyond?
A key unknown has been the behavior of clouds in a hotter world. If the future is cloudier, more sun will be blocked, helping cool the earth. But fewer clouds mean more solar energy will be soaked up by land and sea. Now, thanks to cutting edge new research out of Australia, some of that undercertainty has been cleared up. The future has never looked hotter.
We reached the lead author in this new study, Professor Steve Sherwood at the University of New South Wales, in Australia.

Steve's new paper "Spread in model climate sensitivity traced to atmospheric convective mixing" was just published in the journal Nature. It's caused a stir in the media and climate science, by predicting much more heating than we expected, due to changes in cloud formation.
Paper abstract here.

Steve's bio on "The Conversation"
As participants in the comments section outline, water vapor that is not drawn high enough to develop into clouds may become atmospheric rivers of moisture instead. That is what flooded Boulder Colorado - not a cloud-driven storm, but an atmospheric river precipitating out rapidly.
I'll be talking more about "atmospheric rivers" next week with Dr. David Lavers, who published a paper showing intense rainfall events will increase in the United Kingdom (and likely the world) as the climate warms. Listen in for that (and my analysis of a super-storm that could wipe out California agriculture and cities).
CALIFORNIA IS NOT WILDLY RADIOACTIVE FROM FUKUSHIMA! ARNIE GUNDERSEN
Arnie Gundersen of Fairewinds
It seems like every week there is a storm of new rumors about Fukushima. The Russians secretly report underground explosions beneath the reactors. Reactor three is blowing like an atomic bomb. Get out of California these obscure bloggers and fake journalists say.
I've lived in California, Radio Ecoshock plays on a half dozen stations there, and I'm sick of fear-mongers frightening people there when it simply isn't true. Yes there are worries about Fukushima radiation, especially in sea food. Yes, some very weak radiation will arrive on the California coast. But no, my surfer friends don't need to be afraid to get out on the waves!
One particular video has gone viral, showing an unidentified dude carrying a geiger counter down to a California beach. It reads higher than background levels and voila! proof of Fukushima horrors! Except, as Arnie Gundersen tells us, a local group took sand samples from that same beach, and found the radioactivity was NOT from Fukushima. There are identifiable traces for Fukushima radiation, and we now know scientifically those (low) levels of radiation on that beach are from previous nuclear testing, or even natural local sources.
All through this continuing disaster at the triple melt-down in Fukushima Japan, Radio Ecoshock has depended upon several voices of expertise. One is Arnie Gundersen, the nuclear engineer and whistleblower now at Fairewinds and Associates. Here is six minutes of sanity from Arnie's latest podcast and video, courtesy of Fairewinds Energy Education. Watch the video here.
Don't think for a minute I'm downplaying the super risks of the triple melt-down in Japan. But let's worry about real things, not Net panic.
BRUCE LOURIE - GETTING TOXICS OUT OF OUR BODIES
Are you accumulating harmful chemicals and metals in your body? It's probably so bad - most of us don't want to know. And what about all those magic pills and therapies to detox? Do they work?
Following their book "Slow Death by Rubber Duck," the team of Rick Smith and Bruce Lourie are back with a new book about the toxins we take in, and ways to get them out.
Bruce Lourie
Bruce Lourie is a well-known speaker and writer about ecology. He's the President of the Ivey Foundation, with degrees in environmental studies and geology. He is co-author of "Toxin, Toxout, Getting Harmful Chemicals Out of Our Bodies and Our World".

Before we all get too depressed, the second theme of this book is "Toxout" - the ways people try to clean up what has already arrived. On page one hundred and two of the book, you have a handy chart of detox methods that have or have not been proven effective. We discuss with the methods that don't have any scientific backing so far, and may be a waste of time and money.
Then we get into what does work. For example chelation therapy does remove heavy metals from our bodies, like mercury or lead. But that's only for people who have been diagnosed with that problem by a medical doctor. Bruce says don't try that at home kids.
The team of Smith and Lourie tested out several different detox methods, experimenting on themselves. Surprisingly, a simple sauna can be shown to bring out toxic chemicals from the skin pores. Saunas work! That leads to a discussion about our social drive to stop people from sweating. It turns out sweat is nature's way of removing harmful things from our bodies. Using antiperspirants with aluminum is doubly dangerous: we intake the aluminum, and stop the export of toxic chemicals.
And watch out for toxic chemicals and metals leaching out of cosmetics into your body! It's all in the book.
The book is ""Toxin, Toxout, Getting Harmful Chemicals Out of Our Bodies and Our World" I put off reading if for a week, being nervous about what I might find out. Instead, I found some really useful and sane solutions to protect the body. It's a good readable guide from authors Rick Smith and Bruce Lourie.

DANIEL KAMMEN - "DENSIFICATION" DOESN'T WORK; SUBURBS POWER CLIMATE CHANGE
Dr. Daniel A. Kammen
No doubt you've heard people living in dense cities use less energy, and create fewer emissions. Since National Governments are doing practically nothing to confront climate change, cities are trying to lower their carbon footprint. But is the whole concept of densification working?
The answer to that question leads to deeper matters: How can we live with less, doing less damage, and still be who we are?
We're fortunate to get some insight from our next guest. Daniel M. Kammen is a heavyweight in energy research. He's advised everyone from the World Bank to the American government. Daniel is a member of the National Academy of Science and played a leading role in two reports of the Intergovernmental Panel on Climate Change. Right now he's a Professor of Energy at the University of California, Berkeley, and Director of the Renewable and Appropriate Energy Laboratory. He's written 12 books, hundreds of scientific papers, and advised governments on Energy Policy.

Daniel has a brand new paper out in the journal Environmental Science & Technology. The title is: "Spatial Distribution of U.S. Household Carbon Footprints Reveals Suburbanization Undermines Greenhouse Gas Benefits of Urban Population Density."
One of the key concepts in this paper is the Household Carbon Footprint, or HCF.
Find some cool maps that show greenhouse emissions for most of America right here.
On Radio Ecoshock, I've played you several speeches on new urban design. The latest big push is to create super cities to reduce emissions from commuting and other energy use. It's called densification, but is it working? You may be surprised to learn that 20 percent of all emissions world-wide come from just one place - the American suburbs, the place where many listeners live.
One of the prime messages in this new paper on U.S. Household Carbon Footprints - is that the movement to simply pack more people into cities, to reduce carbon emissions, isn't working in the real world.
Reading Daniel's energyblog in National Geographic, he attends many of the power conferences around the world, from Abu Dhabi to London. I ask Daniel if he thinks leaders in large institutions and corporations realize we are on the brink of a climate catastrophe. Are people at the top getting the message?
Here is a link to Daniel's blog on the National Geographic web site.
