New Study: Warming Trend Since 2013 From Increased Absorbed Solar Radiation, Not CO2
by Kenneth Richard Dec 26, 2024
The 2013-2022 warming trend and the extreme warmth in 2023 were “not associated with” declining outgoing long-wave radiation induced by rising greenhouse gases. [emphasis, links added]
Instead, a new study published in the journal Science contends that decreasing cloud albedo and the consequent increase in ASR, or absorbed solar radiation (+0.97 to 1.10 W/m²/decade according to ERA5 and CERES, respectively) explains the warming over the last decade. (Less cloud cover means more solar radiation reaches the Earth’s surface, warming it.)
A rising trend in anthropogenic greenhouse gases was supposed to reduce the Earth’s outgoing long-wave radiation (OLR), and a declining OLR was thought to be the driver of modern warming.
Instead, the opposite has occurred. There has been an increasing OLR trend since 2013.
