New Opinion article: @bjornhs, @LJ_Wilcox and Robert Allen highlight an urgent need for more research into the complex climate effects of regional changes in aerosol emissions
journals.plos.org/climate/ar…
Bjørn H. Samset retweeted
2023 temperatures fall in line with historical trends, with warm anomalies typical of El Niño, indicating dominance of sea surface temperature variability and regional forcing.

Hva er egentlig sammenhengen mellom luftforurensning og nedbør og hvordan påvirker det klimaet? Det vet forskerne stadig mer om! @gunnarmy og @bjornhs har bidratt til denne vitenskapelige gjennomgangen i @NatureGeosci

Maybe @Nature should stop ignoring the role of rapid aerosol reductions in its communication on near term warming?
As that's where most risks are, as written in @Nature

Ein klar konsekvens av varmare vatn og varmare luft er meir ekstremnedbør. Det er vanskeleg å varsle og vanskeleg å forebygge. @Nansensenteret @uib @bjornhs @cicero

Det kraftige regnværet er en følge av de nyhetene vi har fått servert i uker og måneder nå: Verden blir varmere.
– Når verden blir ekstra varm, så fører det til at vannet fordamper – og det må ned et sted, sier @bjornhs ved @CICERO_klima.

Why on Earth is this behind a pay wall?! 🤌
Please remove the paywall 🙏
Good thing there is this great interview from @PeaseRoland with Laura Wilcox @LJ_Wilcox.
Other authors: @ggpersad, @bjornhs
xitter.cf/LeonSimons8/status/160…
From 9 minutes in @PeaseRoland talks to Laura Wilcox @LJ_Wilcox about the unmasking of the effects of global warming (whole episode is worth listening to).

- Vi i Norge har ikke forstått alvoret i klimakrisen, sa @bjornhs @CICERO_klima på Politisk frokost m. #statsvitenskap @oivinbr @UniOslo #climate. Sol- og vindkraft vil, ifølge ham, være viktigst i det grønne skifet. Samset tok til orde for mer tverrfaglig forskning på klima.

Introducing RAMIP: a set of experiments designed to diagnose the climate impact of near-future changes in regional aerosol emissions gmd.copernicus.org/preprints… Simulations are just getting started, so please get in touch if you’d like to join us!
Bjørn H. Samset retweeted
This is an important piece in Nature making the case for better modeling of aerosols in downscaling and emulators.
But let’s be clear: the ~0.5C or so additional warming from getting rid of aerosols is already baked into our deep mitigation scenarios. nature.com/articles/d41586-0…

Closer to home, @AtmosScience Laura Wilcox warns that reducing atmospheric pollution as we shut down fossil burning is going to exacerbate (in the short term) global warming due to CO2 ... such as a 40% increase in the heatwaves like China saw this year.
Bjørn H. Samset retweeted
Wow, very interesting, and concerning article. The warming that comes from reduced air pollution creates more harm than the same warming from CO2.
Most models do not take aerosols into proper account. nature.com/articles/d41586-0…
