Rising ocean surface temperatures caused by global warming have increased the temperature and moisture content of the air passing over the United States, thus setting the stage for heavier snow and rainstorms.
Recent cold weather and heavy snow in the United States has people thinking that climate change is not happening. They think a few cold snaps prove global warming is a hoax. Do not be fooled by these people.A few snowstorms, cold snaps or even heat waves do not prove anything about climate change, because there is a significant difference between weather and climate. Weather is what we experience on any given day or even over a couple of weeks. Climate describes a region’s prevailing conditions — including such things as temperature, rainfall, wind, humidity and atmospheric pressure — over long periods of time.
Putting aside the difference between weather and climate, climate change projections show that a warming planet generates more precipitation in areas that typically experience rain or snow. This means areas that get a lot of rain and snow will see larger more intense storms and regions that are dry such as deserts will receive less rain.
“Climate scientists aren’t at all surprised that there are more drenching rain or blizzards in certain parts of the country,” says Dr. Brenda Ekwurzel, a climate scientist with the Union of Concerned Scientists (UCS). “That’s consistent with well-documented climate change trends over the past several decades. Unless we take some dramatic steps to curb global warming, we likely will see a lot more regional precipitation over the next few decades.”
