Arctic Sea Ice

Ice has both ecological and economic benefits and its extent could influence weather around the world.


El Niño

El Niño is a warming of waters in the equatorial Pacific that influences global weather patterns.


Ocean Acidification

Acidifying oceans can hurt coral reefs and shellfish as well as the people that rely on them for their livelihoods.


Carbon Dioxide

CO2 is a potent greenhouse gas and plays a vital role in regulating Earth's surface temperature through radiative forcing and the greenhouse effect


Extreme Heat

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.
