Three Years Later: The Moore Tornado’s Path of Destruction

When Rick Smith, a forecaster with the National Weather Service office in Norman, Okla., woke up on the morning of May 20, 2013, he knew it was going to be a bad day. “It just had that feeling of doom,” he said. It was the peak of tornado season and Norman, situated in the open, green flats of central Oklahoma, lies in the heart of tornado country.


The Shum Show: Hot like Hemsworth

Spring is in the air! But so are snowflakes, hailstones, and even graupel (what’s that?!). Find out what April’s heat means for 2016 overall on this week’s Shum Show with Climate Central’s Multimedia Journalism Fellow, Greta Shum.

‘99 Percent Chance’ 2016 Will Be Hottest Year

Odds are increasing that 2016 will be the hottest year on the books, as April continued a remarkable streak of record-warm months. Last month was rated as the warmest April on record by both NASA and the National Oceanic and Atmospheric Administration, which released their data this week. In the temperature annals kept by NOAA, it marked the 12th

A Global Warming 101 Chat With Climate Scientist Scott Denning

Professor Scott Denning at Colorado State University is an atmospheric scientist and climate expert. Professor Denning does an excellent job of taking complex subjects and breaking them down to explain the science in an easy to understand manner – no small feat! I recently asked Prof. Denning to address some of the basics of the greenhouse


The New Normal: Earth is Getting Hotter

As the planet continues to warm from the increase in greenhouse gases in the atmosphere, the temperatures that we consider to be normal are also rising. What younger generations consider very warm today may seem especially hot to their grandparents. NOAA publishes climatological normals every decade based on 30-year average temperatures; the most

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.
