This report makes it clear that the currently observed global warming is not natural. The IPCC is the body set up under the auspices of the United Nations. 2500 scientists from around the world gathered in Paris from January 29th to February 2nd, and they confirmed the unnatural and the fast warming up of the earth's atmosphere.
