Cacti are severely threatened by drought in a warming world

A study spanning the Americas finds that climate forecasts underestimate threats to biodiversity by excluding extreme weather events, which become more likely in a warmer world.
The analysis reports that even exceptionally resilient cacti face severe habitat loss across the Americas.
Projections that include severe drought predict serious declines for these species, according to Nature's coverage.

Why it matters

Biodiversity forecasts that rely on long-term climate averages may understate risk to species, so conservation planning that ignores extreme droughts could miss real threats.
