The Intergovernmental Panel on Climate Change

• The Intergovernmental Panel on Climate Change (IPCC) is the international body for the assessment of climate change. It was established by the United Nations Environment Programme (UNEP) and the World Meteorological Organization (WMO) in 1988 to provide policymakers with regular assessments of the scientific basis of climate change, its impacts and future risks, and options for adaptation and mitigation.

• The IPCC reviews and assesses the most recent scientific, technical and socio-economic information produced worldwide relevant to the understanding of climate change. It does not conduct any research nor does it monitor climate related data or parameters.

• As an intergovernmental body, membership of the IPCC is open to all member countries of the United Nations (UN) and WMO. Currently 195 countries are Members of the IPCC.

• The IPCC embodies a unique opportunity to provide rigorous and balanced scientific information to decision-makers because of its scientific and intergovernmental nature. The assessments are policy-relevant but not policy-prescriptive.

What is the IPCC?

AR6 schedule

• Assessment Reports (AR) - the state of scientific, technical and socio-economic knowledge on climate change, its causes, potential impacts and response strategies:

three Working Group reports, together with their Summaries for Policymakers, and a Synthesis Report;

will be finalized in 2021-2022.

• Special Reports (SR)

proposals submitted for IPCC consideration by Member States and Observer Organisations;

complement the AR6, scientifically focused;

cross-Working Group assessment of timely topics;

may integrate different proposals in a coherent framework;

three SR’s planned during AR6:

Special Report on impacts of global warming of 1.5°C (SR1.5)

Special Report on climate change and oceans and the cryosphere (SROCC)

Special Report on climate change, desertification, land degradation, sustainable land management, food security, and greenhouse gas fluxes in terrestrial ecosystems (SR2)

• Methodology Reports - provide practical guidelines for the preparation of greenhouse gas inventories:

the first report scheduled will refine the 2006 IPCC Guidelines for National Greenhouse Gas Inventories during AR6.

Sixth IPCC Assessment Cycle products

• The United Nations Framework Convention on Climate Change (UNFCCC) invited the IPCC to develop 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;

• The IPCC accepted the UNFCCC’s invitation at its 43rd Session (11-13 April 2016, Nairobi, Kenya), noting the context of strengthening the global response to the threat of climate change, sustainable development and efforts to eradicate poverty;

• The Special Report (SR1.5) will be developed under the joint scientific leadership of Working Groups I, II and III with support from the WGI Technical Support Unit (TSU).

Special Report on impacts of global warming of 1.5°C

• Coordinating  Lead  Authors (CLA) coordinate the content of the chapter they are responsible for. There are usually two CLAs per chapter;

• Lead  Authors (LA) work in teams to produce the content of the chapter on the basis of the best scientific, technical and socio-economic information available. In the course of the assessment process LAs may also enlist Contributing Authors who provide LAs more technical information on specific subjects covered by the chapter;

• Review Editors assist the Working Groups in identifying reviewers for the expert review process, ensure that all substantive expert and government review comments are appropriately considered.

• The composition of CLAs and LAs aims to reflect a range of scientific, technical and socio-economic views and expertise; geographical representation; a mixture of experts with and without previous experience in IPCC; and gender balance.

SR1.5: scoping, writing, review

• The scoping meeting was held in Geneva, Switzerland on 15-18 August 2016;

• 130 participants (invited experts and Bureau Members) were invited to discuss the scope, outline, and contents of the report. Purposely, a pre-defined structure for the report was not provided to the participants;

• A draft outline for the Special Report was developed in an iterative process of plenary and break out group sessions over the course of the scoping meeting.
