Carbon dioxide levels reached the highest seasonal peak recorded in 61 years of observations at NOAA's Mauna Loa observatory. This the seventh consecutive year of steep global increases in concentrations of this important greenhouse gas pollutant.
New research by NOAA and partners based on extensive sampling of the global ocean finds that the ocean absorbed 34 billion metric tons of carbon from the burning of fossil fuels from 1994 to 2007 — a four-fold increase to 2.6 billion metric tons per year when compared to the period starting from the Industrial Revolution in 1800 to 1994.
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.
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.
