James Hansen's Must-See TED Talk: Starting To Reduce CO2 In 10 Years Is Too Late http://apocadocs.com/s.pl?1332172477
Favorite denier myths such as "it's the Sun" and "CO2 lags temperature" were addressed by Dr. Hansen and shown to be wrong or irrelevant. He also discussed how amplifying feedbacks in the past took small changes in temperature due to slight changes in the Earth's orbit and either initiated or ended ice ages. He then said these same amplifying feedbacks will occur today if we do not stop the warming. "The physics does not change."
Besides the impacts that are already occurring, Dr. Hansen said that if we do not stop the warming, we should expect sea levels to rise this century by 1 to 5 meters (3 to 18 feet), extinction of 20 to 50 percent of species, and massive droughts later this century. He said that the recent Texas heat wave, Moscow's heat wave the year before, and the 2003 heat wave in Europe we "exceptional" events that now occur 25 to 50 times more often than just 50 years ago. Therefore, he concluded, we can say with high confidence that these heat waves were "caused" by global warming.
A key solution to climate change, Dr. Hansen said, is to out a simple, honest price on carbon. He proposed a "Fee and Dividend" approach where an increasing fee on CO2 is paid by fossil fuel companies and 100 percent of the proceeds are distributed to every legal resident. Besides lowering carbon emissions, this will also stimulate innovation and create millions of jobs.
