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 meeting to draft the outlines of each of the three Working Group contributions to the AR6 was held on 1 - 5 May 2017 in Addis Ababa, Ethiopia. The draft
outlines will be considered by the Panel when it meets in September 2017
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 will be finalized in September 2018
Special Report on the Ocean and Cryosphere in a Changing Climate (SROCC)
At its 43rd Session (Nairobi, Kenya, 11 - 13 April 2016), the IPCC decided to prepare a special report on climate change and the oceans and the cryosphere.
During its 45th Session (Guadalajara, Mexico, 28 - 31 March 2017), the Panel approved the outline of the Special Report on the Ocean and Cryosphere in a Changing Climate to be
finalized in September 2019.
The Special Report will be developed under the joint scientific leadership of Working Groups I, II and III with support from the WGII TSU.

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 and III supported by the WG III TSU.

2019 Refinement to the 2006 IPCC Guidelines for National Greenhouse Gas Inventories
At the 43rd Session of the IPCC in April 2016, the Panel agreed to refine the 2006 IPCC Guidelines for National Greenhouse Gas Inventories, including producing a Methodology Report
in order to update and supplement the 2006 IPCC Guidelines. Work on the Guidelines is necessary to update and provide a sound scientific basis for future international climate action
especially under the Paris Agreement. This process will result in a Methodology Report which will be used in conjunction with the 2006 IPCC Guidelines. At its 44th Session, the Panel
approved the outline for the 2019 Refinement to the 2006 IPCC Guidelines for National Greenhouse Gas Inventories.
The Methodology Report will be finalized in May 2019
The Expert Review of the First Order Draft of the IPCC Special Report Global Warming of 1.5 °C will run from
31 July to 24 September 2017. Registration will be open until 17 September 2017.
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.
