Is global warming unstoppable now? Could we be saved by total economic collapse? If so, should we help civilization fall?

Last night I recorded another glimpse of the climate apocalypse, with the author of Climate Wars Gwynne Dyer. He outlined the short distance from here to the cliff where long-known natural feed-backs leading to runaway global warming begin, and continue on for millennia. That limit is known as two degrees. Beyond that, great forests melt into fire, liberating their carbon. Beyond that, the Arctic permafrost melts, likely doubling atmospheric greenhouse gases. Five to seven degrees Centigrade of average global temperature rise. Utter disaster.

Dyer says world governments quickly agreed to the 2 degree limit at Copenhagen, without telling the public why. No need to panic the herd.

Dyer says we won't make it in time, before the big climate switch is pulled. You'll hear clips from that speech in an upcoming Ecoshock Show. I can't run the whole speech, because as usual, Gwynne is developing his new work toward another radio or TV program. I appreciate Gwynne sharing his "working notes" with our Radio Ecoshock audience. Kind of a sneak preview.

"Stabilization of carbon dioxide emissions at current rates will require approximately 300 gigawatts of new non-carbon-dioxide-emitting power production capacity annually -- approximately one new nuclear power plant (or equivalent) per day," Garrett says. "Physically, there are no other options without killing the economy."
