I don't understand why a glacier would survive longer in the 4°C scenario than 2.5°C but this seems to suggest so.

- Perz1val 23d agoWater has the highest density at 4°C, but I have no idea how that'd relate
- dfdydx 23d agoIt's +4°C (from the average global temperature). The glacier itself won't be at 4°C.
- abdullahkhalids 23d agoThe system is highly non-linear and has a lot of flippable components. For example, average temperature increase will cause the AMOC to collapse which will make parts of Europe cooler (while also increasing extreme weather events). Similar things could happen with whichever glacier you are looking at.
- burkaman 23d agoThe data comes from this paper, I don't immediately see an answer to this question though: https://www.nature.com/articles/s41558-025-02513-9 https://www.nature.com/articles/s41558-025-02513-9. My guess is that the climate is complicated and the planet doesn't warm evenly, so different emissions scenarios might imply different regions warm more quickly. Not all the glaciers on the site survive longer in the +4 scenario, it's only some parts of the world.
- chunky1994 23d agoThat's just an artifact of the graphical display. This paper shows that's not the case (see fig 2): https://www.nature.com/articles/s41558-025-02513-9 https://www.nature.com/articles/s41558-025-02513-9
