Global Warming:

International computer projections for the next 100 years all agree that the world's average temperature will rise. How high depends upon greenhouse gas build up, but the range will be between 2.5 and 10.5 degrees Fahrenheit. To put that into perspective, if we go back to the last time the earth was 10 degrees cooler than it is now, we have to go back at least ten thousand years to the end of the last Ice Age. So, it took 10,000 years for the earth to warm up 10 degrees F. since ice last covered North America, but may take only the next 100 years to heat up another 10 degrees.
