I attended a Swedish Energy Agency meeting today where they shared three scenarios (not forecasts) for how county-level electricity use in Sweden might change.

I made a web tool to visualize it – way more fun than Excel. LOTS of power use in Norrbotten by 2050

I’ve built a tool and animation showing changes in Arctic sea ice thickness, comparing 1980 with 2024.
👉 Pay special attention to September, when the ice is at its thinnest. Ignore the hole in Greenland 😀

Best experienced on a computer.

New study in @climate-policy.bsky.social showing that it is possible to reduce emissions, decrease inequality and strengthen welfare and the economy. Lowering fuel taxes is inefficient from multiple perspectives.

We are experimenting with how to represent yearly data in a compact way using 3D models. This is a model showing the electricity spot prices for Sweden for all 8760 hours in 2024. January 1 00:00:00 lower left, January 7 23:00:00 lower right, and December 31 23:00:00 upper right.

Tittar på Agenda om klimatet från häromdagen. Forskarna och SVT gör ett bra jobb. Mest intressant från politikerna är ju inte vad de säger, utan vad de inte säger.
