Not really, not any more. This isn't 10 years ago. Very few scientists with any national standing or international standing say it doesn't exist anymore. The overwhelming consensus is that it's very real, it's here, and it's happening far faster than we thought. The question is how much man can influence it or attenuate it. Go to nationalgeographic.com and enter "global warming", they've had some good articles with all sides discussed.
