The IPCC prepares its sixth report on climate change and a special report on desertification
The Intergovernmental Panel on Climate Change (IPCC) was present at COP23 with a lecture on their activities and preparation in addition to the Sixth Assessment Report, three special reports and a methodological report on Day of the Guidelines for National Greenhouse Gas Inventories.
The first of these special reports, which will be finalized in September 2018, is entitled: Global warming of 1.5 ° C: IPCC special report on the consequences of a global warming of 1.5 ° C compared to pre-industrial levels and related patterns of change in global greenhouse gas emissions, in the context of strengthening the global response to climate change, sustainable development and poverty reduction..
The methodological report entitled Revision 2019 of the IPCC 2006 Guidelines for National Greenhouse Gas Inventories will be published in May 2019.
In September 2019, the IPCC will also publish two special reports: the climate change and land-surface special report: IPCC special report on climate change, desertification, land degradation, sustainable land management, food security and flows of greenhouse gases in terrestrial ecosystems, this report will be prepared at the request of Algeria and other countries concerned by this problem. The third special report will be devoted to the Ocean and the Cryosphere in the context of climate change.
The contributions of the three working groups to the Sixth Assessment Report will be published in 2021 and the synthesis report in April 2022.
The purpose of the IPCC reports is to regularly provide decision-makers with assessments of the science of climate change, its consequences, the associated risks, and the opportunities for adaptation and mitigation.
Through IPCC assessments, authorities at all levels have scientific information that can be used to develop climate policies. These assessments have a central place in international negotiations on action to address climate change. For the sake of objectivity and transparency, IPCC reports are drafted and revised in several stages.
The IPCC evaluates the thousands of scientific articles published each year to inform policy makers of knowledge and gaps in the area of climate change risks. It determines the elements on which the scientific community agrees, those on which opinions diverge and those which require further research. The IPCC does not conduct its own research. To prepare its reports, the IPCC mobilizes hundreds of scientists. The IPCC members are the 195 member governments. The latter proceed by consensus to approve the IPCC reports.
The IPCC has three working groups: Working Group I, responsible for the scientific elements of climate change; Working Group II, Focusing on Impacts, Adaptation and Vulnerability, and Working Group III, which studies mitigation of climate change. It also has a special team on National Greenhouse Gas Inventories, which is developing methods to measure greenhouse gas emissions and removals.
The IPCC evaluation reports are developed from the contributions of each of the three working groups, plus a Synthesis Report. Cross-cutting issues that fall under the three working groups are the subject of special, shorter and more focused reports than the evaluations presented in the main reports.
The Director of the CDER, Prof. Noureddine YASSAA is a member of the IPCC Bureau as the Vice Chair of IPCC Working Group I, which deals with scientific elements of climate change.
