Overview

Analysis reveals a 25-fold increase in extreme compound droughts and heatwaves in humid regions, highlighting urgent climate adaptation needs.

Key Points

  • Compound droughts and heatwaves (CDHW) in India have intensified significantly over the last 60 years.
  • The area affected by CDHW events has increased from 10% to 35%, shifting from arid to humid regions.
  • Over 46% of moderate and 43% of elevated CDHW events escalated in severity, indicating increasing extremes.
  • Urban populations in emerging hotspots are exposed to evolving CDHW risks, emphasizing the need for improved climate adaptation.
