Global Warming is both increasing and decreasing our chances of having snow days.
Our chances for a snow day are increasing because global warming is causing the earth to become warmer, as the term suggests. It causes large bodies of water, like lakes, not to freeze. This influences more water to evaporate and turn into heavy snowfall.
As evidence of this, look to the winter of 2009-2010, there were many severe snowstorms, including two storms that hit Philadelphia that were considered “once in a hundred years” snowstorms.
However, even though snowstorms are becoming harsher, winter has become shorter because of global warming. Winter in the United States comes later every year. The average first freeze from 1971 to 1980 was a week earlier than the average from 2007 to 2016, according to Weather.com. However, the end of winter has generally remained the same.
And that is decreasing our chances of snow days because winter has become shorter.
To sum it up, you can’t blame global warming for our lack of snow days this year, but you also can’t give it credit for our huge number of snow days last year.
