A global early warning system for predicting exposure of biodiversity to extreme heat (opens in new tab)

Effective biodiversity conservation during periods of rapid environmental change requires identifying the species and regions at greatest risk. However, most predictions focus on biodiversity shifts several decades ahead, offering limited guidance for immediate conservation action. Here we develop an early warning system for biodiversity based on 9-month seasonal weather forecasts combined with species-specific historical temperature limits. In May 2024, we predicted that >3,500 vertebrate sp...
