The true health burden of climate change

Patchy, short-term health data obscure the true burden of climate change-related death and illness in current impact assessments, argues climate scientist Dann Mitchell. The reports must take into account the toll that long-term exposure to heat and drought will have on our bodies. Researchers need to consider how community health is affected by warming conditions and study the socio-economic impacts of recovering from climate disasters.

Why we still don’t know the mounting health risks of climate change

Persistent exposure to heatwaves, droughts, wildfires and more will take a toll on people’s bodies. We must learn how this will manifest.

The consequences for our bodies of repeated exposure to heat, drought and wildfire smoke will mount. But climate assessments are not yet taking this into account.
