Climate models show carbon emission mitigation could slow Arctic temperature increases

NOAA-led research using climate model projections concludes the Arctic climate will continue to show major changes over the next decades, but that carbon emission mitigation could slow temperature changes in the second half of the century, according to a paper published by AGU’s Earth’s Future.

A more acidic Arctic? NOAA deploys first buoy in region to monitor levels of CO2 absorbed by ocean

NOAA’s Pacific Marine Environmental Laboratory in partnership with the Marine Research Institute in Iceland deployed the first high-latitude ocean acidification monitoring buoy in the Atlantic Ocean in early August. The moored buoy is the first of its kind to be deployed north of the Arctic circle in a region where very little is known about how carbon dioxide (CO₂) is entering the ocean environment.

Like butter: Study explains surprising acceleration of Greenland’s inland ice

Surface meltwater draining through cracks in an ice sheet can warm the sheet from the inside, softening the ice and letting it flow faster, according to a new study. During the last decade, researchers have captured compelling evidence of accelerating ice flow at terminal regions, or “snouts,” of Greenland glaciers as they flow into the ocean along the western coast.

Arctic nearly free of summer sea ice during first half of 21st century

For scientists studying summer sea ice in the Arctic, it’s not a question of “if” there will be nearly ice-free summers, but “when.” A new study says it could be before 2050.

Thin, low Arctic clouds played an important role in the massive 2012 Greenland ice melt

Clouds over the central Greenland Ice Sheet last July were “just right” for driving surface temperatures there above the melting point.

Arctic continues to break records in 2012: Becoming warmer, greener region with record losses of summer sea ice and late spring snow

NOAA scientists participated in a panel discussion of the annual Arctic Report Card, which has summarized the quickly changing conditions in the Arctic since 2006.

NOAA, National Archives team up with citizen-scientists to reconstruct historical climate of the Arctic

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.

Arctic summer wind shift could affect sea ice loss and U.S./European weather

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.
