Intergovernmental Panel on Climate Change
Who and What is the IPCC:
The Intergovernmental Panel on Climate Change was set up by the World Meteorological Organization (WMO) and the United Nations Environmental Programme (UNEP) in 1988, to compile information and develop understanding regarding the
potential threat of anthropogenic climate change. The panel is comprised of over 2500 scientific expert reviewers, 800 contributing authors, and 450 lead authors from 130 countries. The organization does conduct scientific research itself or monitor climate data. It bases it's conclusions mainly on scientific/technical writings published in scientific journals and other peer-reviewed publications.
The main goal of the IPCC is to provide assessments about "the state of knowledge on climate change" in regular intervals.
