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.

A decade ago, solar power barely registered in Hungary’s electricity mix — just 0.2% of generation. Back then, nuclear, coal, and gas dominated the grid.
Fast forward ten years and solar power now supplies around 1/4 of Hungary’s electricity — a remarkable transformation.
