Multiple studies report that climate change—especially more frequent and intense extreme drought—substantially increases the extinction risk for cacti across the Americas. The research highlights that common biodiversity projections can underestimate harm when they rely mainly on long-term climate averages and omit extreme weather events.
Phys.org and Nature coverage emphasizes that even cacti, which are often viewed as resilient, face major losses of suitable habitat under warmer, drier conditions. Nature presents findings based on assessments of many cactus species, describing severe habitat loss driven by drought and warming, with projections that include worst-case drought impacts.
Across the outlets, the main differences are framing and emphasis. Phys.org stresses the broader point that forecasts are missing threats to biodiversity because they do not factor in extremes. Nature focuses on drought’s pressure on “iconic” species and details that severe drought and warming shrink the climatic space cacti can occupy, using analyses that explicitly incorporate extreme-event assumptions.
