Overview
- UNHCR’s No Escape II report tallies roughly a quarter-billion weather-related internal displacements worldwide over the past decade.
- By mid-2025, 117 million people were displaced by war, violence and persecution, with three-quarters living in countries facing high or extreme climate hazards.
- The number of countries with extreme exposure to climate risks is projected to jump from three to 65 by 2040, and those states host more than 45 percent of people displaced by conflict.
- The hottest 15 refugee camps could face nearly 200 days of hazardous heat stress each year by 2050, raising serious threats to health and habitability.
- UNHCR says donor retrenchment, including steep U.S. foreign aid cuts, is limiting protection capacity and calls on COP30 to direct climate financing to vulnerable host communities.
