A paper published today in the Bulletin of the American Meteorological Society presents a review of the current state of knowledge regarding extreme weather.
The authors, most of whom are from NOAA, find no significant trends in severe thunderstorms, overall ice storms, or change in the percentage of the contiguous US impacted by extreme snowfall. According to the authors, trends in tropical cyclones are controversial and indeterminate, although other authors find global cyclone activity is at a historical low. The authors state, “attribution of trends to anthropogenic forcing [man-made global warming] remains controversial.”
