For the first time since we began tracking carbon dioxide in the global atmosphere, the monthly global average concentration of this greenhouse gas surpassed 400 parts per million in March 2015, according to NOAA’s latest results.
After quantifying the airborne emissions from the nation’s third largest ethanol refinery, a team led by NOAA and University of Colorado–Boulder researchers has found that for some gases, refining ethanol releases more to the atmosphere than previously thought—and in some cases more than is ultimately released by burning the fuel in vehicles. The emissions can contribute to the formation of ozone, a regulated pollutant that can affect human health. Results are published in a paper published online by Journal of Geophysical Research.
The American Chemical Society will designate the Keeling Curve – a long-term record of rising carbon dioxide in the planet’s atmosphere -- as a National Historic Chemical Landmark in a ceremony April 30 at NOAA’s Mauna Loa Observatory in Hawaii.
A team of scientific investigators is now in the Four Corners region of the U.S. Southwest, aiming to uncover reasons for a mysterious methane hotspot detected from space by a European satellite. The joint project is working to solve the mystery from the air, on the ground, and with mobile laboratories.
While research shows that nearly all coral reef locations in the Caribbean and Gulf of Mexico will experience bleaching by mid-century, a new study showing in detail when and where bleaching will occur shows great variety in the timing and location of these harmful effects.
The new research published today in Global Change Biology by NOAA scientists and colleagues provides the first fine-scale projections of coral bleaching, an important planning tool for managers.
If you’ve ever sailed aboard a ship in the ocean, or checked a weather report before heading to the beach, then you are one of many millions of people who benefit from ocean observations. NOAA collects ocean observations and weather data to provide mariners with accurate forecasts of seas, coastal weather forecasts and regional climate predictions. Partnerships are essential to maintaining a network of free-floating, data-gathering buoys known as drifters. NOAA’s latest partner is not your typical research or ocean transportation vessel: the six sailboats and crew currently racing around the world in the Volvo Ocean Race.
In Alaska’s Bering Strait and Arctic regions, there are dozens of Alaskan Native tribes, many of whom depend on the marine environment for food, as they have in some cases for thousands of years. In this world more foreign to most Americans than many other countries (and bigger than many too) works exactly one NOAA Oceanic & Atmospheric Research Sea Grant extension agent: Gay Sheffield.
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.
