IPCC — Intergovernmental Panel on Climate Change
[IPCC-62, WGI-15, WGII-13, WGIII-15](https://www.ipcc.ch/meeting-doc/ipcc-62/) [Vacancies](https://www.ipcc.ch/about/vacancies/)
Through its assessments, the IPCC determines the state of knowledge on climate change. It identifies where there is agreement in the scientific community on topics related to climate change, and where further research is needed. The reports are drafted and reviewed in several stages, thus guaranteeing objectivity and transparency. The IPCC does not conduct its own research. IPCC reports are neutral, policy-relevant but not policy-prescriptive. The assessment reports are a key input into the international negotiations to tackle climate change. Created by the United Nations Environment Programme (UN Environment) and the World Meteorological Organization (WMO) in 1988, the IPCC has 195 Member countries. In the same year, the UN General Assembly [endorsed the action by WMO and UNEP in jointly establishing the IPCC](https://www.ipcc.ch/site/assets/uploads/2019/02/UNGA43-53.pdf).
