Clouds over the central Greenland Ice Sheet last July were “just right” for driving surface temperatures there above the melting point.
Before satellites, weather data transmitters, or computers, there were the ship's logs of Arctic sea voyages. A new crowdsourcing effort could make the weather data from these ship logs available to climate scientists worldwide.
Changes in summer Arctic wind patterns contribute not only to an unprecedented loss of Arctic sea ice, but could also bring about shifts in North American and European weather.
The concentration of carbon dioxide in the atmosphere of Barrow, Alaska, has reached a new milestone this spring, according to NOAA measurements.
Bering Sea marine mammals, birds, and fish are shifting where they eat, bear their young, and make their homes in response to changes in sea ice extent and duration.
Arctic warming has thinned springtime sea ice across the Arctic Ocean. A new study shows that this alters the chemistry of the atmosphere near the Earth’s surface and may increase the amount of toxic mercury contaminating the region.
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.
