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.
The amount of air pollutants in the atmospheric plume generated by the Deepwater Horizon oil spill was similar to a large city according to a new NOAA-led study published today in a special issue of Proceedings of the National Academy of Sciences.
Scientists have found a large reduction in the amount of the coldest deep ocean water, called Antarctic Bottom Water, all around the Southern Ocean using data collected from 1980 to 2011.
In a new study, academic and NOAA scientists found that ozone pollution is declining at rural sites in the East, but is steady or even increasing at most sites in the rural West, with strongest increases in spring.
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.
