Numerous media outlets cited last week’s polar vortex as an example of extreme weather caused by climate change, but it turns out such cold snaps are actually on the decline. Roy Spencer, principal research scientist at the University of Alabama in Huntsville, posted a graphic of November-March cold waves in the East and Midwest dating back to 1895 that flies in the face of the “global warming causes extreme cold” argument. The theory has it that the decline of Arctic sea ice, which has dropped by about 15 percent over the last 40 years, has disrupted the polar vortex, causing it to move southward, but the data assembled by Mr. Spencer and UAH professor of atmospheric science John Christy showed otherwise.
