The Shum Show: You Better Watch Out!

La Niña is bringing with her some extra cold this winter, but what does that mean for climate change? Find out with Climate Central's Research Analyst/Multimedia Journalist, Greta Shum, on the Shum Show!

It’s Finally Going to Feel Like Winter in the U.S.

Winter is coming. Finally. After months on end of warmth across the country, cold air will finally arrive for much of the U.S. next week. The chill will start in the West as Arctic air spills down and turns the map blue from Alaska to the Southwest and then migrates eastward as the week goes on. Temperatures could dip down to 30°F below normal

The March Continues for 2016 to be Record Hot

Global temperatures have begun to retreat from their El Niño-fueled peak earlier in the year, but the excess heat trapped by greenhouse gases is keeping them well above average and 2016 is likely to become the hottest year on record. The National Oceanic and Atmospheric Administration released its temperature data through the end of October on

Second-Warmest October Cements Hottest Year

October was the second hottest on record for the planet, NASA data released Tuesday shows. The month was the latest in a string of record- and near record-warm months that will see 2016 easily take the title of hottest year in the books. While an exceptionally strong El Niño helped to boost temperatures early in the year, most of the excess heat

This is Your Winter Outlook for the Mid-South

By the end of March 2013, we were more than ready to put winter behind us after bitterly cold temperatures hanging on and periods of snow blanketing the area. We were influenced by a weak La Niña episode and arctic air was readily available to the Eastern U.S. Currently, the Climate Prediction Center is in "La Niña Watch" mode with a 70 percent


Climate Indicators

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.


Global Temperature

The global temperature is the clearest measure of how human greenhouse gas emissions are affecting our planet.
