Increasing frequency and magnitude of extreme heat can affect health, power usage and more.


Snow Cover

A shorter snow season increases the amount of sunlight absorbed by the Earth’s surface and can further warm the planet.


Sea Level Rise

Sea level rise could force millions to leave coastal areas and cost the world trillions of dollars.


Land Ice

Melting land ice contributes to sea level rise.


U.S. Wildfires

Wildfires damage forests and release CO2.
