Some regions may already be living in a 1.5°C warmer world

from Phys.org

Regions worldwide may have already experienced around 90%–94% of the warming expected when the global average reaches 1.5°C above preindustrial levels, and 65%–76% of that expected at 2°C of warming. The findings, published in Nature Climate Change, suggest that regional warming in 2025 was statistically indistinguishable from the levels expected in a 1.5°C warmer world, underlining the immediate need for adaptation across all regions.

how it works

Global warming is an average over the whole planet. Land heats faster than sea, and high latitudes faster than the tropics, so a regional temperature can be well above the average while the global figure still sits below a target.

so what

The 1.5°C goal is usually discussed as a number the world has yet to reach, but for many places the local experience has largely arrived. The authors say this makes adaptation urgent in all regions, not only the ones that warm fastest.
