Global Warming??

After seeing the graph on page 169 of our text which shows the dramatic temperature increace since the industrial revolution that has grown steeper since the 70's, I cant imagine that anyone truly beleives global warming is not happening. Many people just dont care about the environment or think a little warmer weather would be nice. However these people are ignorant to the horrific effects of globel warming that have been happening over the past decades, as well as being unaware of the positive feed back loop where warmer weather produces more greenhouse gases and like the graphs this happens at an exponential rate. However, just saying the temperature is increasing gives skeptics to much to work with. So to aid the class in proving to people everywhere that global warming is happening and is bad I have two links. The first link shows two different NASA studies about the shrinking of the ice caps, and the second link discusses the decline of the frogs.
