Special Report on Global Warming of 1.5 °C (SR15)

Following the decision of the panel at its 43rd Session to accept the invitation from the UNFCCC, at its 44th Session, the Panel approved the outline of Global Warming of 1.5 °C, an IPCC special report on the impacts of global warming of 1.5 °C above pre-industrial levels and related global greenhouse gas emission pathways, in the context of strengthening the global response to the threat of climate change, sustainable development, and efforts to eradicate poverty.
The report was finalized in October 2018

Sixth Assessment Report

The IPCC is currently in its Sixth Assessment cycle. During this cycle, the Panel will produce three Special Reports, a Methodology Report on national greenhouse gas inventories and the Sixth Assessment Report (AR6).
 
The 43rd Session of the IPCC held in April 2016 agreed that the AR6 Synthesis Report would be finalized in 2022 in time for the first UNFCCC global stocktake when countries will review progress towards their goal of keeping global warming to well below 2 °C while pursuing efforts to limit it to 1.5 °C. The three Working Group contributions to AR6 will be finalized in 2021.
 
The outlines were approved by the Panel at its 46th Session in early September 2017.

Special Report on Climate Change and Land (SRCCL)

At its 43rd Session (Nairobi, Kenya, 11 - 13 April 2016), the IPCC decided to prepare a special report on climate change, desertification, land degradation, sustainable land management, food security, and greenhouse gas fluxes in terrestrial ecosystems. At its 45th Session (Guadalajara, Mexico, 28 - 31 March 2017), the Panel approved the outline of Climate Change and Land: an IPCC special report on climate change, desertification, land degradation, sustainable land management, food security, and greenhouse gas fluxes in terrestrial ecosystems. The report will be finalized in September 2019.
 
The Special Report will be developed under the joint scientific leadership of Working Groups I, II, III and the Task Force on National Greenhouse Gas Inventories, with operational support from the Working Group III TSU.

IPCC Resource Mobilization

Assessments of climate change by the IPCC, drawing on the work of hundreds of scientists from all over the world, enable policymakers at all levels of government to take sound, evidence-based decisions. They represent extraordinary value as the authors volunteer their time and expertise. The running costs of the Secretariat, including the organization of meetings and travel costs of delegates from developing countries and countries with economies in transition, are covered through the IPCC Trust Fund.
