Climate change causes millions of deaths, illnesses, and economic losses globally via heat, pollution, and extreme weather.

Why it matters

  • Shows climate change is already causing significant health and economic impacts.
  • Urges policy action to address climate-related health risks.

By the numbers

  • 271,656 heat-related deaths across 43 countries (1991-2018).
  • Billions in economic losses, including US$300M/year for heat-related preterm births in China.
  • Fossil fuel companies like Chevron linked to 59 heat-related deaths in Switzerland.

The big picture

  • Current research focuses heavily on high-income countries and temperature-related risks.
  • Future studies needed to address diverse health impacts and regions.

Caveats

  • Research bias towards high-income countries.
  • Limited studies on infectious diseases and non-communicable diseases.

What’s next

  • More research on diverse health impacts and geographic representation.
  • Focus on uneven impacts within populations.
