Intergovernmental Panel on Climate Change
A lot of IPCC work is publishing reports about the United Nations Framework Convention on Climate Change (UNFCCC),  an international agreement that human inventions and chemistry may make the Earth too hot to live on. The UNFCCC was the beginning of the Kyoto Protocol. Members of the IPCC read, write, and calculate as much as they can. Only member states of the WMO and UNEP may be members of IPCC.
