Assessing the performance of solar radiation management geoengineering simulations - Frontiers of Earth Science
Offsetting the global warming caused by anthropogenic increases in atmospheric greenhouse gases by deliberate injection of aerosols into the stratosphere is the most studied of solar radiation management geoengineering schemes. The long-term success or failure of such schemes in achieving their stated goals is assessed by comparing simulated geoengineered temperature, precipitation and tropical cyclones metrics to equivalent fields in the simulated targeted climate simulations. Results using available data sets from three single model stabilized climate target experiments and three multimodel climate change reduction experiments are presented and compared against a measure of internal variability. While all but one experimental scheme is successful in achieving their targeted global mean annual surface temperature, their success at regional scales varies significantly and is often larger than the internal variability metric used here.

The attack on @frediotto.bsky.social was seeded years ago by Roger Pielke Jr, who started arguing that this table from a recent @ipcc.bsky.social report proved that climate science cannot attribute extreme weather to climate change.
But Roger is of course lying. And we know this for 2 reasons.

A resonance phenomenon is causing big waves in the atmosphere. And that has increased due to #globalwarming, causing wild summer extremes, a new data analysis finds.
The mechanism was first identified in 2013 by the late Vladimir Petoukhov at the Potsdam Institute.

The flooding of the Guadalupe River in Texas was undoubtedly made worse because of climate change. I would estimate that there was 7-20% more rainfall than w/o the human interference in the climate. But w/o detailed attribution studies on the storm and associated runoff, we can't know for certain.
