The Intergovernmental Panel on Climate Change is a United Nations body set up under the UN Framework Convention on Climate Change to research and advise the global Climate Change negotiations.
Climate Change deniers and sceptics accuse the IPCC of being under government control. That is not the case. All parties and sectors are involved in the IPCC, and the research is adopted by governments, not dictated by them.
There is however a significant Trojan Horse effect from allowing the large Energy, Engineering and Mining corporations to be involved.
