By measuring the carbon-14 isotope in air from more than 200 years ago, the researchers found that scientists have been vastly overestimating the amount of fossil methane emitted by natural sources, and have therefore been underestimating the amount of methane humans are emitting into the atmosphere via fossil fuels.

Four factors to consider in the race to solve the climate crisis, including how to scale up a tool called negative emissions and why the oceans can only help so much.

The polar vortex usually encompasses the polar region in the winter stratosphere, but sometimes shifts markedly away from its normal position and distorts during stratospheric sudden warmings (SSWs).

The window of time available to make and use ice roads is closing.

What is it like to do science nearly 2 miles above sea level?

A new international advisory system is working to keep aircraft crew and passengers safe from space weather impacts, thanks in part to the efforts of a team of CIRES and NOAA developers, forecasters, and scientists in Boulder, Colorado.

Research finds importance of Antarctic sea ice towards the global glacial cycle.

Study helps scientists better understand the vertical structure of the atmosphere.

Climate change is being felt in a corner of the world different from where one might expect: Wall Street, where some of the biggest investors are starting to take action.

Scientists have taken a major step toward a circular carbon economy by developing a long-lasting, economical catalyst that recycles greenhouse gases into ingredients that can be used in fuel, hydrogen gas, and other chemicals.
