In the past year we've had a series of papers with results that've shocked #climate scientists - the globe is heating #FasterThanExpected & we don't fully know why The public discourse is not keeping up. Here's a series of 5 new studies that climate hawks & journos need to have on their radar 🧵

Happy to see this out! Meltwater can delay future surface warming, and its interannual variations impact ocean stratification & overturning.​​ This effect is usually absent from models. Including it as forcing may lead to more realistic simulation of surface temperature and sea ice trends🧊🌊 (1/7)

Would you believe it: just 10 days after #EarthCARE went through the eye of Hurricane Humberto, it did the same with Hurricane Priscilla in the East Pacific on 7 October! A very different beast this one: a huge eye around 100 km across, and very lopsided, with much more rain on the southern side.

I just updated this NASA CERES graph. The regional level of Absorbed Solar Radiation increased by 4.2 W/m² in 20 years!! That's more than the global greenhouse gas forcing increase since 1750! The 2 W/m² Net Flux increase indicates that there is a lot more regional warming in the pipeline.
