Scientists Split on Human Impact on Climate ChangeA Purdue University survey shows that the scientific community is split on the question of whether human activities are at the root of climate change, with just over 50 percent of scientists saying that climate change is happening and that it is caused mostly by human activities.
The Media Research Center reports that the studys findings differ largely from the often used statistic that 97 percent of scientists believe in man-made global warming.

Also, as far as global warming goes, 97% of all journal articles that are peer reviewed agree that there is indeed global warming.
The debate in these journals is not weather the Earth is warming, all reasonable scientist believe that. The debate is whether it is fast or slow and human caused or nature caused.

What is a bit confusing is to "why" and "how much". Some say nature, some say humans are the main cause. But almost all of the 97% say it is a mixture. They just disagree upon how much it is mixed up. Some say it will be a little bit of a problem, some say it will be a big problem, but most of the 97% agree that sooner or later there will be problems of some sort.
