Special Reports produced in the IPCC’s Sixth Assessment Cycle
IPCC Special Report on Climate Change and Land (2019)
A report on climate change, desertification, land degradation, sustainable land management, food security, and greenhouse gas fluxes in terrestrial ecosystems. This report addresses greenhouse gas (GHG) fluxes in land-based ecosystems, land use and sustainable land management in relation to climate change adaptation and mitigation, desertification, land degradation and food security.

Chapter 2: Land-Climate Interactions
IPCC Special Report on the Oceans and Cryosphere in a Changing Climate (2019)
A report drafted under the joint scientific leadership of IPCC Working Groups I and II, and prepared by 104 authors and review editors from 36 countries. 6,981 publications were referenced in the whole report. This report addresses changes in high mountain and polar regions, sea level rise and its implications for low lying islands and coastal areas, changes to the oceans and marine ecosystems, and the possibility of abrupt changes in the oceans and cryosphere. As this is a report that spans all three IPCC working groups, each chapter traces the impacts of climate change from its physical manifestations through to their impacts on ecosystems, people and societies.
