🌡️🌾 When heat hits twice, crops pay the price.
New study coauthored by IIASA’s @kornhuber.bsky.social with @ethz.ch & @vuamsterdam.bsky.social shows back-to-back heatwaves cut yields of maize and wheat.
⚠️ Such events could be 10× more frequent without climate action.

In the lead up to the Overshoot Conference @iiasa.ac.at Sep 30-Oct 2, the organizers had a fantastic nerdy idea to get the leading experts in their fields share their perspectives on the key themes. Highly recommend for your daily commute, background to cooking etc.: open.spotify.com/show/5MpXqh1...
