The Intergovernmental panel on climate change (IPCC) is the United Nations body for assessing the science related to climate change. Their assessment report are at the core of global discussions about climate actions. The IPCC does not conduct its own research, but identifies areas of agreement and disagreement among scientists, as well as point towards areas where more research is needed. The IPCC is now working on its sixth assessment report (AR6), from which the Synthesis report is due in 2022.
Three working groups contribute to the assessment report, and CBA researchers are part of Working group 1: The physical science basis. Professor Trude Storelvmo is coordinating lead author on Chapter 7: The Earth’s energy budget, climate feedbacks, and climate sensitivity. This means she has an overarching responsibility for the chapter, as well as contributes to the understanding of feedback mechanisms related to aerosols and clouds.
Professor Terje Koren Berntsen is lead author on Chapter 6: Short-lived climate forcers. He is responsible for predictions on how short-lived climate forcers (methane, ozone precursors (CO, NOx, hydrocarbons), aerosols) are expected to contribute to changes in global middle temperature for different emission scenarios (SSP scenarios) until the year 2100.
In March, the last version from the authors was delivered (Final government draft). It will move on to Approval in end July at the Fifty-fourth Session of the IPCC (IPCC-54) and WGI AR6 Approval Plenary.
