Climate Dice are Loaded, says Hansen

January 1, 2013; 6:07 PM ET

Dr. James Hansen, who is the director of NASA's Goddard Institute for Space Studies (GISS) recently talked to Climate One host Greg Dalton about whether or not there was a human fingerprint on Hurricane Sandy.

Hansen explains how extreme weather events are becoming more frequent. He also discusses how the potential for stronger hurricanes is increasing and that the hurricane season is getting longer.

Counter argument

Hurricane expert Dr. William Gray along with Philip Klotzbach of the Colorado State University, who write an annual summary of the Atlantic basin tropical cyclone activity each year, explain that although a storm like Hurricane Sandy is extremely rare, this type of tropical cyclone is well within natural variability and should not be attributed to increases in human-induced greenhouse gases.

Gray and Klotzbach do not believe that Hurricane Sandy and other destructive tropical cyclones of the past ten years are a direct consequence of human-induced global warming. Any impacts of climate change on hurricanes are believed to be quite small and within the noise level, according to Gray and Klotzbach.
