Polar ice caps are melting.
This year, there was documented evidence of significant melting at both poles. And the U.S. Space Agency, NASA, and others, confirm the Earth has warmed nearly two degrees since 1900. That may not sound like much, but warming temperatures fuel extreme weather patterns. And a recent study suggests continued global warming could raise sea levels several meters by the end of the century.
The southern ice sheet is over 2200 meters thick, on average. That amounts to 90 percent of the world's ice and 70 percent of its fresh water.
