Read James Hansen’s ‘Perception of Climate Change’ study

James Hansen, director of NASA’s Goddard Institute for Space Studies and author of “Storms of My Grandchildren,” will be on “Viewpoint” tonight to discuss “Perception of Climate Change,” a new study he co-authored with Makiko Sato and Reto Ruedy, which was published in Proceedings of the National Academy of Sciences on Monday, Aug. 6.

From the study:

“We can state, with a high degree of confidence, that extreme anomalies such as those in Texas and Oklahoma in 2011 and Moscow in 2010 were a consequence of global warming because their likelihood in the absence of global warming was exceedingly small.”
