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.
A new buoy, launched by NOAA and partners at the mouth of Chesapeake Bay, will measure changes in ocean acidification that could impact the bay and its valuable shellfish.
The strong El Niño event of 2015-2016 provided NASA and NOAA an unprecedented opportunity to test the effectiveness of the newest observation tool to measure global atmospheric carbon dioxide concentrations -- NASA’s Orbiting Carbon Observatory-2 satellite or OCO-2.
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
Ocean acidification is spreading rapidly in the western Arctic Ocean in both area and depth, potentially affecting shellfish, other marine species in the food web, and communities that depend on these resources, according to new research published in Nature Climate Change by NOAA, Chinese marine scientists and other partners.
For the first time, NOAA and partner scientists have connected the concentration of human-caused carbon dioxide in waters off the U.S. Pacific coast to the dissolving of shells of microscopic marine sea snails called pteropods.
Analysis of nearly three decades of air samples from Alaska’s North Slope shows little change in long-term methane emissions despite significant Arctic warming over that time period, according to new research published in Geophysical Research Letters.
Human activity has increased the direct warming effect of carbon dioxide (CO2) in the atmosphere by 50 percent above pre-industrial levels during the past 25 years, according to NOAA's 10th Annual Greenhouse Gas Index .
Rising levels of acidity in the ocean and growing areas of low-oxygen waters are a “double whammy” threat for fishing industries, ecosystems and economies along the U.S. West Coast and Canada’s British Columbia, according to new report by a panel of experts that includes NOAA scientists.
The Office of 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.
