Global Warming

The earth is heating up, no one can say that is isn't. Today on science we watched a video about global warming and the effects that we are having from it. If the earth keeps heating up, glaciers would fall and the ocean would rise 20 ft! Thats only Greenland, but if Antartica's glaciers fell the ocean would rise the same amount. Greenhouse gases are killing us, slowly. There is so much pollution going around. Air pollution, water pollution, and more. Hurricanes and storms are increasing in size and in appearance. They are showing up in places where scientists thought that they couldn't. We have to do something or else in 50 or 70 years, there may not be very much that we can protect.
