New research shows that atmospheric concentrations of a class of ozone-depleting chemicals used as refrigerants, foam blowing agents, and solvents peaked in 2021, and are now beginning to decline as nations comply with Montreal Protocol restrictions.
NOAA’s Seamless System for Prediction and EArth System Research (SPEAR) shows great skill at predicting year-to-year variability in wind energy, especially in spring over the Southern Great Plains, where more than half of the total U.S. wind capacity is located.
If the future sea surface temperature warming pattern continues to resemble the observed pattern from the past few decades rather than the model-simulated/predicted patterns, we can expect a drastically different future projection of high-impact storms, especially over the Western Hemisphere.
Our ocean and coasts are home to a diversity of life from the smallest single-celled plankton, to the largest animal on Earth, the blue whale. The ocean provides us with vital resources and plays a large role in the climate of our planet.
As a climate solution, marine carbon dioxide removal is an important pathway to achieve the broader goal for the U.S. to reach net-zero emissions of greenhouse gases by 2050.
Carbon dioxide measured at NOAA’s Mauna Loa Atmospheric Baseline Observatory surged to a seasonal peak of just under 427 parts per million (426.90 ppm) in May 2024. That’s an increase of 2.9 ppm over May 2023 and the 5th-largest annual growth in NOAA’s 50-year record.
A study finds that the Arctic Ocean transition from summer heating to autumn cooling aligns closely with the September 22 equinox.
Atmospheric changes, particularly shifts in the North Atlantic Oscillation, which controls most of the winds over the North Atlantic region, have redirected storm tracks toward Taklamakan and Gobi Deserts.
Variations in the Atlantic Meridional Overturning Circulation and changes in wind-driven ocean currents combine with long-term global warming to raise sea level along the U.S. Southeast Coast.
The Department of Commerce and NOAA just announced $60 million in funding to help train and place people in jobs that advance a climate-ready workforce for coastal and Great Lakes states, Tribes and Territories.
