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.
Middle and high school students in six cities across America have won the chance to deploy a NOAA global ocean drifter for Earth Day, earning the opportunity to launch a small 44-pound floating buoy into an ocean current.
NOAA scientists are using a newly upgraded powerful high performance computer to improve our understanding of the Earth’s climate system.
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.
On Wednesday, March 14, two NOAA scientists will take questions over Twitter about ice cover on the Great Lakes over the past few months and on the long-term trends.
NOAA’s Great Lakes Environmental Research Lab has monitored ice cover on the lakes for decades. Its measurements have documented wide variations from winter to winter and made possible discoveries about climate links to variation in ice cover.
