Arctic cyclones may be accelerating sea ice loss by breaking ice into smaller pieces and driving upwelling of warm water. A ...

The Arctic's "Last Ice Area" (LIA)—a vital habitat for ice-dependent species—might disappear within a decade after the central Arctic Ocean becomes ice-free in summer, which is expected to ...

Since 1979, Arctic sea ice extent, a term that describes the area of the Arctic Ocean covered by ice, has been reduced by 40% in the late summer months. Global climate models have consistently ...

Ice nucleating particles as a kind of aerosols have a significant impact on the Arctic climate by promoting the formation of ice clouds at a temperature above -38˚C. Wildfires in mid-latitudinal ...

The Arctic air over the Great ... demonstrates kite skiing during the Lake Superior Ice Festival in Superior on Saturday, Jan. 25. The ice concentration graphs do show an overall rapid increase ...

Wildfire aerosols from Canada, Alaska, and Russia, including organic carbon, are transported to the Arctic, influencing ice cloud formation at temperatures warmer than the typical −38°C.

The ice core samples show there is more carbon dioxide in the earth’s atmosphere now than in the past. They also show that the level is increasing much faster than it has over thousands of years. Data ...

There is indirect evidence that, during the last interglacial period, about 125,000 years ago, parts of the West Antarctic Ice Sheet retreated. An ice core ... of the concentration of sea salt ...

And what happens in the Arctic trickles down to all of us. "If the sea ice disappears, the Arctic will warm faster and the planet will warm faster," Lehner said. Scientists say to slow the melting ...

A combination of increased microbial activity, thawing permafrost, and more frequent wildfires now means the Arctic is releasing more carbon dioxide than ... Snow and Ice Data Center at the ...

Dark algae that grow on the surface of Arctic ice sheets are likely to expand their range in the future, a trend that will exacerbate melt, sea level rise and climate warming. “These algae are ...
