By linking Antarctic sea ice, cloud cover, deep ocean temperatures, and global warming, our new study led by @linusvogt.bsky.social finds that ocean heat uptake and thermal sea level rise by 2100 could be 3–14% higher, and global surface warming 3–7% greater than previously thought👇
🚨🌊 New highlight paper out today in Earth System Dynamics!
We find an observational constraint implying more future global ocean heat uptake, cloud feedback, and warming than the CMIP6 mean.
This contrasts with previous estimates based on past warming trends.

New study led by @lilianschuster.bsky.social finds that temporarily overshooting +1.5°C leads to irreversible glacier loss and long-term changes in water runoff. Some fast-responding glaciers may regrow, but this could lead to water scarcity centuries later, a phenomenon called ‘trough water’.👇
