A NOAA study published in the journal Nature demonstrates a profound effect of the Montreal Protocol: as levels of ozone-depleting chemicals controlled by the intenational treaty declined, a poleward shift of summertime circulation patterns in the Southern Hemisphere halted.
A new NOAA study in the Journal of Climate warns that in the already warm and frequently dry southern Great Plains and Southwest, climate change will make compound heat-wave and drought events significantly hotter than they used to be.
Carbon dioxide levels measured at NOAA’s Mauna Loa Atmospheric Baseline Observatory averaged more than 410 parts per million in April and May, the highest monthly averages ever recorded.
On Friday, August 25, U.S. Coast Guard Cutter Healy will sail from Dutch Harbor, Alaska, with a team of NOAA scientists and collaborators on a 22-day cruise to study environmental change in the western Arctic Ocean.
This summer, NOAA and partner scientists will conduct their most collaborative ocean acidification sampling of the Gulf of Mexico yet. Set to depart today, July 18
New collaborative research between NOAA, University of Alaska and an Alaskan shellfish hatchery shows that ocean acidification may make it difficult for Alaskan coastal waters to support shellfish hatcheries by 2040 unless costly mitigation efforts are installed to modify seawater used in the hatcheries.
Oceanic and Atmospheric Research (OAR) - or "NOAA Research" - provides the research foundation for understanding the complex systems that support our planet. Working in partnership with other organizational units of the NOAA, a bureau of the Department of Commerce, NOAA Research enables better forecasts, earlier warnings for natural disasters, and a greater understanding of the Earth. Our role is to provide unbiased science to better manage the environment, nationally, and globally.
