Section 1 of 5What is the IPCC?
The Intergovernmental Panel on Climate Change (IPCC) is the United Nations body responsible for assessing the science related to climate change. Founded in 1988, the IPCC produces comprehensive assessment reports that synthesize the latest scientific research on climate change, its impacts, and potential response strategies.
Unlike typical scientific organizations, the IPCC doesn't conduct its own research. Instead, it relies on the peer-reviewed scientific literature to provide policymakers with regular assessments of the state of knowledge about climate change. The IPCC has been awarded the Nobel Peace Prize for its efforts to build up and disseminate greater knowledge about climate change.
