The media says "2024 was the hottest year and the first above 1.5°" but that is NOT the story.
THIS ist the story:
The average of the last 36 months (aka 3 years) is now at 1.52°C above average.

Identifying hotspots of greenhouse gas emissions from drained peatlands in the European Union - Nature Communications
An EU-wide analysis shows that drained peatlands are major, underreported sources of greenhouse gases. By mapping emission hotspots, the study provides guidance for targeted rewetting and strengthens ...
