IPCC was established in 1988 by the World Meteorlogical Organization or the WMO. It was established to test the climate changes that were based on the most latest science available to man, in relation to climate effects.
The person who is the head of the IPCC is Rajendra K. Pachauri, and he was born in 1940. He was later replaced by Hoesung Lee.
Scientist have found that changes in the earths climate are caused by geothermal energy, tidal energy from the moon and heat decay of radioactive compounds. Also short term and long range variations of solar intensity have been known to affect the global climate of the earth.
Major factors causing climate change or global warming are land use changes, aerosols, soot, and greenhouse gases.
