Yes, the earth is getting warmer, but it will get cooler again. I've read so much about people saying it's us that's causing it. Here's what I say: Quit ordering stuff online that has to be delivered by a jet and a truck, quit driving your car to work, quit going on vacation, quit eating out, quit buying everything you eat and grow it ... not going there are you? Earth has a natural cycle; who put out forest fires 200 years ago? Icebergs were in Oklahoma 10,000 years ago; my lawnmower didn't melt them. If you're that worried, do something about it!
