I thought this story was interesting. New research from studying Greenland ice cores suggests that we've had much more rapid global warming that we've been experiencing in recent years.

The ice core showed the Northern Hemisphere briefly emerged from the last ice age some 14,700 years ago with a 22-degree-Fahrenheit spike in just 50 years, then plunged back into icy conditions before abruptly warming again about 11,700 years ago.

If man is really the primary reason for global warming, then why did we see this 22 degree change in just 50 years at a time when we didn't have SUVs running around the earth? We're talking about changes of a degree over a hundred year period and yet this newly discovered change is much more dramatic in a shorter period of time.

As I've said before. I don't deny that the climate is changing. I don't deny that man's activities have an impact. My problem is with those who say that the "science is settled" and that anyone who suggests that perhaps man isn't completely responsible are suddenly "global warming deniers" and on par with members of the Nazi party. How can we expect to find out the best approach for dealing with global climate change if we only allow one opinion? It just doesn't make sense.
