Atmospheric Rivers: ocean map shows Pineapple Express pattern
September 14, 2016
A high-resolution climate model based at NCAR is accurately capturing the ribbons of moist air that sometimes flow out of the tropics toward the drier mid-latitudes, allowing scientists to investigate how the Pineapple Express and similar weather-maker patterns may change as the climate warms.
Sulfates could limit global warming - image illustrates volcano plume
September 06, 2016
If society doesn't make steep cuts in greenhouse gas emissions in the next few decades, how much injection into the atmosphere of planet-cooling sulfates would it take to limit warming to 2 degrees Celsius above preindustrial levels?
Mount Pinatubo's caldera on June 22, 1991
August 10, 2016
Greenhouse gases are already having an accelerating effect on sea level rise, but the impact has so far been masked by the cataclysmic 1991 eruption of Mount Pinatubo in the Philippines.
Image of Antarctic sea ice in 2014

The recent trend of increasing Antarctic sea ice extent — seemingly at odds with climate model projections — can largely be explained by a natural climate fluctuation.
Capping at 2 degrees: photo of entrance to COP21, Paris climate conference
June 27, 2016
A new study finds that, even if all the countries follow through on their Paris Agreement commitments, steeper emissions cuts would be necessary after 2030 to stay below 2 degrees of warming.
climate modeling 101: four maps show increases in climate model grid resolution
June 20, 2016
A new open-access book demystifies climate modeling without using a single equation.
