Climate models project that combinations of heat and humidity could reach deadly thresholds for anyone spending several hours outdoors by the end of the 21st century. However, new NOAA-supported research says these extremes are already happening — decades before anticipated — due to global warming to date.
Eight new postdoctoral fellows are commencing cutting-edge research projects that will contribute innovative climate science to the research community as well as NOAA’s mission.
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.
The discovery of a novel sulfur compound during a 2017 NASA airborne research campaign will likely spur a scientific reassessment of a fundamental marine chemical cycle which drives the formation of oceanic clouds that play a key role in moderating climate. “People thought the sulfur budget was well understood,” said NOAA scientist Patricia Quinn, who was not involved in the study. “This throws a kink in the whole works.”
Using a new powerful NOAA global climate model, NOAA and partner researchers show that big storm-induced spikes in sea levels will increase in the future from the Gulf Coast to the Atlantic coast as warming progresses, but will be driven by differing forces.
Air & Sea Chronicles
Editor's note: Air & Sea Chronicles is NOAA's blog series documenting the ATOMIC mission in Barbados. This post is by Cindy Sandoval, a communications specialist from NOAA Fisheries who was on detial assisting NOAA Communications with ATOMIC outreach.
Over 50 Barbadian or Bajan students toured NOAA Ship Ronald H. Brown during the vessel’s short port call in Bridgetown, Barbados. While aboard, students learned about NOAA’s mission, the role the vessel plays in cutting-edge research, and why their island nation is at the center of an unprecedented effort to better understand the interactions of atmosphere and ocean.
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.
