More accurately predicting periods of increased hurricane activity weeks in advance may become possible due to new research published this month. Research from NSF NCAR shows that twice as many hurricanes form two days after the passing of large-scale atmospheric waves called Kelvin waves than in the days before.

Greenhouse gas concentrations, the global temperature across land and the ocean, global sea level, and ocean heat content all reached record highs in 2023, according to the 34th annual State of the Climate report.

A team of scientists proposes specific recommendations for evaluating proposals to inject sulfur dioxide into the stratosphere.

NSF NCAR scientists have linked together multiple state-of-the-art computer models to create a detailed picture of how conditions in the atmosphere affect the ocean; how the ocean, in turn, affects the growth of phytoplankton and zooplankton; and finally, how the small fish that eat zooplankton (and the bigger fish that eat them) are impacted.

NSF NCAR scientists are studying key aspects of wildfires.
