If we don't rapidly phase out fossil fuels, we can say goodbye to coral reefs, the Greenland and Antarctic icesheets, and permafrost. The results will not be pretty.

Friday ice update - #Arctic sea ice extent is currently the 6th lowest on record (JAXA data) • about 120,000 km² below the 2010s mean • about 700,000 km² below the 2000s mean • about 1,220,000 km² below the 1990s mean • about 1,620,000 km² below the 1980s mean More: zacklabe.com/arctic-sea-i... ⚒️🧪
Line graph time series of 2025's daily Arctic sea ice extent compared to decadal averages from the 1980s to the 2010s. The decadal averages are shown with different colored lines with purple for the 1980s, blue for the 1990s, green for the 2000s, and white for the 2010s. Thin white lines are also shown for each year from 2000 to 2024. 2025 is shown with a thick gold line. There is a long-term decreasing trend in ice extent for every day of the year shown on this graph between April and July by looking at the decadal average line positions.

Climate change is making geopolitics less stable, which harms climate action. This will worsen climate change, meaning more geopolitical instability, and so on. The risk is that this “doom loop” runs faster and faster and ultimately derails our ability to phase out fossil fuels fast enough.
