Summary

Story summary

A survey of more than 80 climate researchers in Switzerland finds that limiting warming to 1.5°C is unrealistic, projecting 2.5°C by 2100.
The World Meteorological Organization reports that 2024 was the first year global temperatures exceeded 1.5°C above pre-industrial levels.
Switzerland warms at about twice the global rate and could see 4–4.5°C increases that could lead to the disappearance of over 90% of its glaciers.
