The CESM Large Ensemble reveals a staggering range of Earth climates that could have been along with a rich look at future climates that could potentially be.

The international report detailed potential climate impacts on global food security.

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.

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?

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.
