Beyond the Tipping Point

A physicist, a leading expert on clean energy and climate, he was an advisor in the Clinton Administration. His book "Hell and High Water" becomes too true daily. Time Magazine called him “The Web’s most influential climate-change blogger” . Dr. Joseph Romm's "Climate Progress" is the only blog right on my browser tool-bar. It IS indespensible.

We welcome Joe Romm back to Radio Ecoshock.

Among other things, we'll discuss the new theme issue from the British Royal Society "Four degrees and beyond: the potential for a global temperature increase of four degrees and its implications." This series of papers looks at how the climate will shift drastically - if we continue to power our economy with fossil fuels.

Joe has more on the Cancun climate conference, his award winning blog (named one of the best blogs on the Net by Time Magazine) climateprogress.org - and the bleak outlook for action by the U.S. or Canada.

That is followed by a knock-out interview with David Wadell. His presentation on "Beyond the Tipping Point" at Tallberg Sweden in 2008 warned that the IPCC, and most governments, were operating on unsafe assumptions about climate sensitivity. David tells us about the "positive feedback loops" that are STILL left out of climate models.

And even without those extra warming powers, the Hadley Centre in Britain, and MIT in the U.S. have proved Wasell's point. Both now say we could experience 4 to 6 degrees of warming in this century. Possibly 4 degrees C. warming (7 degrees F. extra heat as a mean global average) as early as 2070, or even 2060. Younger people will live to see this horror, unless we can turn the carbon clock back, in some as yet unknown social and economic revolution.... as we must.

I'm going to let you listen to the interviews, without further comment here.

Here are a bunch of links, so you can test out what Joe Romm and David Wasdell are saying. Going back to the original science. A link bonanza for you. Go deep, this is the Big One.

Pay special attention to this talk by Richard Betts, which includes (at 16 minute mark) the very points David Wasdell raises - that serious positive feedback loops are still left out of climate models (which leads to underestimates of the real possibilities).

Joe Romm's introduction to these papers (and why they matter).

The Royal Society web page for the Philosophical Transactions of the Royal Society "4 Degrees and Beyond" theme issue:

Some of the papers are now subscription only, having been offered to the public for a few days. Given the seriousness of crashing the Earth's climate system, and in the spirit of Wikileaks, I've posted all the papers here, as pdf files.

An elephant does not turn into a mouse.
An elephant cannot be told and made to turn into a mouse.
Complex life forms do not reinvent themselves as simple organisms.

The global supersystem has so many powerful actors, so committed to supertankers and lots of sitting RVs and financial trillions yet to shifted ever upward, that people cannot get away with saying pie-in-the-sky grand plans. Our political and legal and financial and educational systems are shot through with nonsense imperatives and greenwashing superheroes.

We can still think, and despair, and laugh, and go about our business, but we do not have to see green meadows and blue roses and beer ahead of us - we're in too deep.
