Transcript for Snowstorms in the Forecast
the forecast, there w a climate change headline today from some of the nation's top scientists. Saying we should brace ourselves for less snow but more blizzards. So, what does that mean? Abc's david kerley explains. Reporter: It doesn't seem to make sense. Blistering blizzards. Up during the middle of the night and it looked like a blizzard outside. Reporter: Shoveling your sidewalk, you may be asking, this is global warming? I'm ready for spring. Yeah, I'm definitely sick of winter. Reporter: Even the comics are getting in on the snow show. Global warming is a total hoax. And I'll tell you how I know because it's cold. Today. Where I live. Reporter: But new studies confirm what scientists have been saying. We will get less snow. Rutgers scientists have now documented a million scare mile decline of snow cover over nearly 50 years. And a new study from princeton scientists predicts global snowfall over the next 50 years will shinning more than a foot. 30% to 70% drop in snow in the u.S. By the end of this century. But when we do get snow, watch out. Every once in awhile, there's going to be a big storm, a kind of knockout punch. Reporter: Bigger blizzards, but less snow? That's because a warmer at more fear can hold more moisture, sucking it up from the oceans. Most of it will come down as rain. But when it gets cold enough, it will turn into snow, a lot of it. And we could get hit by a monster storm. One of these studies and its predictions is based on computer models and some wonder, how good are the models? But the weather patterns are already changing. Get out your shovels. Snowstorms with two, three feet that used to seem highly unusual, that may, in fact, become more typical. Reporter: Bigger storms, less snow overall. A new reality.
