This has now been completed for 2022. This is related to the commentary we published last year ( Hausfather et al, 2022 ), where we show that this screen is a reasonable match to the IPCC AR6 assessed projections that used emulators constrained by observations. 26-29, 2022. The CMIP3 ensemble continues to astound! Casas, G.A.

New scientific information has yielded insights, including updates to our understanding of, and ability to model, the atmosphere, and the studies of the long-term effects of radiation on affected populations have yielded new information. New studies are being published and commissioned and research gaps are being identified.

The fact that there is a natural greenhouse effect (that the atmosphere restricts the passage of infra-red (IR) radiation from the Earth’s surface to space) is easily deducible from; i) the mean temperature of the surface (around 15ºC) and, ii) knowing that the planet is normally close to radiative equilibrium. in IPCC TAR).

Previous attribution research published by my Union of Concerned Scientists colleagues have allowed us to draw causal connections between sources of heat-trapping emissions and resulting impacts, like present day increases in atmospheric greenhouse gas concentrations, air temperatures, sea levels , ocean acidification , and wildfire burned area.
