Cooperation with the Intergovernmental Panel on Climate Change



The Intergovernmental Panel on Climate Change (IPCC) assesses the scientific, technical and socio-economic information relevant for the understanding of the risk of human-induced climate change.

The IPCC is an independent body founded under the auspices of the World Meteorological Organization (WMO) and the United Nations Environment Programme (UNEP). The IPCC is best known for its comprehensive assessment reports, incorporating summaries for policymakers from a synthesis report and from all three Working Groups, which are widely recognized as the most credible sources of scientific information on climate change. In October 2014, the latest and Fifth Assessment Report of the IPCC (AR5) was finalized.

The Conference of the Parties (COP) has repeatedly expressed its appreciation for the IPCC’s work and called on the Convention bodies, in particular the Subsidiary Body for Scientific and Technological Advice (SBSTA), to continue its cooperation with the IPCC and to seek its advice. It has also urged Parties to contribute financially to the IPCC’s work, as well as to nominate and support experts for the IPCC, especially from developing countries. According to Article 21.2 of the Convention, the secretariat “will cooperate closely with the Intergovernmental Panel on Climate Change to ensure that the Panel can respond to the need for objective scientific and technical advice”.

The IPCC's forty third session, took place in Nairobi, Kenya, from 11-13 April 2016. 1. The IPCC decided to complete the following products in its sixth assessment cycle:

  • A Special Report on the impacts of global warming of 1.5°C above preindustrial levels and related global greenhouse gas (GHG) emission pathways, in response to the invitation by the COP mentioned below;
  • A Special Report on climate change, desertification, land degradation, sustainable land management, food security and GHG fluxes in terrestrial ecosystems;
  • A Special Report on climate change and oceans and the cryosphere;
  • The Sixth Assessment Report. The latter consists of reports from the three IPCC working groups (physical science, mitigation and adaptation), a regional report, a methodology report and a synthesis report.

In decision 1/CP.21, whereby the COP adopted the Paris Agreement, the COP, inter alia:

  • Invited the IPCC to provide a special report in 2018 on the impacts of global warming of 1.5 °C above pre-industrial levels and related global greenhouse gas emission pathways (paragraph 21);
  • Requested the SBSTA to provide advice on how the assessments of the IPCC can inform the global stocktake of the implementation of the Agreement pursuant to its Article 14 of the Agreement and to report on this matter to the Ad Hoc Working Group on the Paris Agreement (APA) at its second session (paragraph 101).

The new IPCC bureau was elected in 2015 opening the way to start the IPCC’s sixth assessment cycle, with the sixth assessment report expected in 5-7 years.

The scientific community has already begun work on CMIP6, led by the WCRP, which will include consideration of scenarios that limit warming in 2100 to below 1.5 °C relative to pre-industrial levels, and the range of impacts at the regional and local levels associated with these scenarios (FCCC/SBSTA/2015/2, paragraph 33).

Upcoming events

The SBSTA–IPCC special event on Assessments of the IPCC and the global stocktake will take place on 18 May 2016 at the World Conference Center Bonn, Meeting room Genf, Bonn, Germany, from 15:00-18:00. More information is available here.
