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?

The advanced Gulfstream-V research aircraft will take critical observations of powerful storms

NCAR and its collaborators have successfully developed cutting-edge forecasts to make solar energy more effective.

NOAA is using an advanced NCAR prediction system as the core of the new National Water Model.

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.
