The IPCC was created by the World Meteorological Organization and the UN Environment Programme
Background
The Intergovernmental Panel on Climate Change (IPCC) provides regular assessments of the scientific basis of climate change.
The assessments cover impacts, future risks, and options for adaptation and mitigation.
It was created in 1988 by the World Meteorological Organization (WMO) and the United Nations Environment Programme (UNEP).
Its objective is to give governments at all levels scientific information they can use to develop climate policies.
IPCC reports are also a key input into international climate change negotiations.
In plain words
Mitigation Action to reduce climate change — Mitigation and adaptation are the two kinds of response the IPCC assesses.
