NASA scientist: Global warming exists; these heat waves are proof
- claim The extreme temperatures felt across the U.S. and the globe in recent years are so crazy that they must be caused by man-made global warming according to James Hansen, a NASA scientist and the “godfather of global warming.”
- evidence “We are now experiencing scientific fact,” Hansen told the AP. He cites three separate heat waves in the past decade — one in the U.S., one in Europe, and one in the Middle East — that statistics suggest were caused by global warming. source
» Some evidence in his favor: In a groundbreaking 1988 study, Hansen claimed that by the 2010s, Washington DC would become so warm that it’d have nine days of heat above 95 degrees per year. So far this year, the District has had 23 days that hit this mark — and now he says he underestimated his own work.
