On August 9th, the Intergovernmental Panel on Climate Change (IPCC) released the Working Group I contributions to the Sixth Assessment Report (AR6), Climate Change: The Physical Science Basis. The report provides the most updated physical understanding of the climate system and climate change, combining the latest advances in climate science, and multiple lines of evidence.

Since the Fifth Assessment Report was released in 2014, advances in monitoring technology have improved the understanding of human influence on the climate.

“It is unequivocal that human influence has warmed the atmosphere, ocean and land. Widespread and rapid changes in the atmosphere, ocean, cryosphere and biosphere have occurred.”¬†IPCC, 2021

The physical science report concludes that limiting the impacts of climate change requires reaching at least net-zero CO2 emissions as soon as possible, along with strong reductions in other greenhouse gases.

We look forward to the reports from the other working groups and the full AR6 report, which will be released in 2022.
