A warmer atmosphere creates more moisture.
…two soon-to-be-published studies demonstrate how there can be more giant blizzards yet less snow overall each year. Projections are that it’s likely to continue with man-made climate change.
Consider, The United States has been hit by twice as many of the most extreme snowstorms in the past 50 years than in the previous 60 years, according to an upcoming study on extreme weather by leading government and university climate scientists. This fits with a dramatic upward trend in extreme winter precipitation, both rain and snow, in the Northeastern U.S. charted by the National Climatic Data Center.
Yet the Global Snow Lab at Rutgers University says that spring snow cover in the Northern Hemisphere has shrunk on average by 1 million square miles in the last 45 years.
And an upcoming study in the Journal of Climate says computer models predict annual global snowfall to shrink by more than a foot in the next 50 years. The study’s author said most people live in parts of the United States that are likely to see annual snowfall drop between 30 and 70 percent by the end of the century.
