Back-to-back heat extremes threaten food production. Our study shows early-season heat makes crops 5–55% more vulnerable to later heat stress. Limiting global warming to 1.5°C can avoid most projected losses. @vuamsterdam.bsky.social @iiasa.ac.at

In 15-20 years, CO₂ from Swiss waste and industry could be stored underground to support #net-zero goals. A pilot project in #Trüllikon near Zurich will explore the best strategy: storing carbon in Switzerland or beneath the North Sea.
