In the future, Santa's reindeer might have trouble finding enough to eat. As this ScienCentral News video reports, it's a result of global warming.Frozen FoodThe North Pole is a cold place, and that's just the way reindeer like it. But climatologists say global warming is affecting their snowy world.
"One of the impacts that scientists are most convinced is going to happen as the earth warms up, is a change in the ratio of snow to rain," says Peter Gleick, president and co-founder of the Pacific Institute. "As the earth warms up, we’re going to get more rain and less snow."
That's a problem for the reindeer because, in cold climates, rain falling on snow creates ice; scientists call this a rain-on-snow event. If it's thick enough, the ice can keep the reindeer from their main food supply, small plants beneath the snow.
