Whats happening with global warming

Did you know that the north pole has been frozen for 100,ooo years? Well, scientists say that by the end of this century that won't be true. Evidence was found that people were contributing to global warming by pumping out greenhouse gases that trap solar heat. This evidence was found by Bob Corell who also said that the seas are rising bringing more chances of stronger hurricanes and that polar bears may become extinct. Polar bears need ice, but a lot of ice is melting because of global warming. I hope that more people will help stop this terrible world disaster before time runs out for the polar bears!
