Re: NASA scientist links climate change, extreme weather
James Hansen? He's not a scientist, he's a political hack. He's just not credible. He claimed a decade ago the waterfront along NYC's east river would be underwater by now due to sea level rise. He claimed in testimony to congress 15-20 years ago that we'd have experienced catastrophic climate change by now... but temps are lower than his best-case scenario (i.e. what temps would be if we kept emissions at 1990 levels).
He's an activist that routinely gets arrested at protests and has called coal trains "death trains". He's biased and his predictions are routinely incorrect.
