2024 is almost history and the global temperature forecast for the remaining few days is rock solid now. Time to wrap up.
In most datasets, 2024 will be 0.1 degree C warmer than 2023. Also, 2024 will be the 1st individual year above the 1.5 degree Paris warming threshold in all datasets.

Bluesky has felt sleepy for a while now. I want to encourage everyone to post more. Text is fine, but you know what? People enjoy damn near any picture of something neat. Food, your bike, a cat, whatever. Also, liking is nice, but reposting is what actually helps exposure.

EVs beat petrol cars on lifetime emissions — even on “dirty” grids.
Battery production is carbon-intensive, but EVs quickly repay that debt and end up 21–71% cleaner over 250,000 km.
We can’t wait for perfect grids: electrify transport and clean the grid now.

Collapse of key Atlantic current could bring extreme drought to Europe for hundreds of years, study finds
Scientists modeled Europe's future if a key Atlantic current were to collapse and found that the continent faces a much drier future.
