Professor Paul Reiter, a scientific expert in malaria, of the Pasteur Institute of Paris, claimed that the United Nations report compiled in February about global warming and the greenhouse effect was a "sham." He claims that his name was included in the report along with 2,000 other leading scientists.

The list of names were claimed to have backed the Intergovernmental Panel on Climate Change's report, although he was one to disagree with the reports' findings. His name was eventually removed after threatening legal action against the panel. He said, "That is how they make it seem that all the top scientists [have] agreed. It's not true."

So if global warming isn't caused by the greenhouse effect, what causes it? Well there's a lot of things in this world that can affect the weather, and not just greenhouse gases. Of course, pollution is still a bad thing. Carbon dioxide has to be dealt with anyway, even if it doesn't cause global warming. If you disagree, you'd better bring that to Uh-nold.

Philip Scott, emeritus professor of bio-geography and at the School of Oriental and African Studies in London, said:

The system is too complex to say exactly what the effect of cutting back on carbon dioxide production would be or indeed of continuing to produce carbon dioxide. It's ridiculous to see politicians arguing over whether they will allow the global temperature to rise by 2 [Celsius] or 3 [Celsius].
