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/articl…

Check out Catherine Toolan's first PhD (preprint) paper. Comments welcome! egusphere.copernicus.org/preprints/2024… inter-model differences and biases in CMIP6 simulations of PM_2.5, aerosol optical depth, and precipitation over Africa /wi @LJ_Wilcox @bjornhs et al.

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. Read this paper by @bjornhs et al. at: nature.com/articles/s4324…

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 nature.com/articles/s4156…

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 nature.com/articles/d4158… @RARohde @JoeriRogelj nature.com/articles/d4158… @ggpersad @bjornhs @LJ_Wilcox

@AndrewIWilliams @DWatsonParris I'm sure someone is very busily doing one at this moment ;-)

@AndrewIWilliams @DWatsonParris Broadly yes, unless you hit a region with a very sensitive pattern effect. (Which Chinese so2 emissions do, in the outflow region.) Other regions tend to all produce very similar patterns - but I agree there's no study (that I know of) specifically for shipping.

Completely agree, it's very irritating to see the shipping emissions angle getting so much traction when it's almost certainly a small factor in the recent extreme Atlantic warmth...

@AndrewIWilliams @DWatsonParris I'm not sure where it is shown most clearly, but e.g. this one. journals.ametsoc.org/view/journals/…

@bjornhs @DWatsonParris Interesting! Is there a paper for that? Would be nice to read more

@AndrewIWilliams @DWatsonParris The aerosol response for strong perturbations has a ramp up time of a few years, so that part actually fits. But I agree with you it's likely a minor part of the current picture.

@DWatsonParris Fully agree that regional effects are probs larger than the CB article's global estimate. But surely the forcing would have had an effect a few years ago? Also the reason for the high temps is linked to the weakening of Azores high and Saharan dust outflow I think...

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 vg.no/nyheter/utenri…

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. vg.no/nyheter/utenri…

- 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.
