Sentences with phrase «while sea ice loss»

While sea ice loss in 2012 had some atmospheric conditions supporting loss at the beginning of summer, the loss in 2012 probably was the result of thin sea ice initial conditions.

«While more research should be done, we should be aware that an increasing number of studies, including this one, suggest that the loss of Arctic sea ice cover is not only a problem for remote Arctic communities, but could affect millions of people worldwide.»

For example, ice loss in far - off West Antarctica will have more profound impacts in Scandinavia than it will in nearby Australia, while right now melting Alaskan glaciers contribute more to sea - level rise in the Baltic than the Greenland ice sheet.

A classic case in point was the discovery that field observations of the loss of arctic sea ice showed that by 2007 it had advanced to a level predicted by the mean of models of that loss as occurring in the 2100s, while that mean was used as the consensus projection in AR4.

Results show that the globally and annually averaged radiative forcing caused by the observed loss of sea ice in the Arctic between 1979 and 2007 is approximately 0.1 W m − 2; a complete removal of Arctic sea ice results in a forcing of about 0.7 W m − 2, while a more realistic ice - free - summer scenario (no ice for one month, decreased ice at all other times of the year) results in a forcing of about 0.3 W m − 2, similar to present - day anthropogenic forcing caused by halocarbons.

There are, however, caveats: (1) multidecadal fluctuations in Arctic — subarctic climate and sea ice appear most pronounced in the Atlantic sector, such that the pan-Arctic signal may be substantially smaller [e.g., Polyakov et al., 2003; Mahajan et al., 2011]; (2) the sea - ice records synthesized here represent primarily the cold season (winter — spring), whereas the satellite record clearly shows losses primarily in summer, suggesting that other processes and feedback are important; (3) observations show that while recent sea - ice losses in winter are most pronounced in the Greenland and Barents Seas, the largest reductions in summer are remote from the Atlantic, e.g., Beaufort, Chukchi, and Siberian seas (National Snow and Ice Data Center, 2012, http://nsidc.org/Arcticseaicenews/); and (4) the recent reductions in sea ice should not be considered merely the latest in a sequence of AMOrelated multidecadal fluctuations but rather the first one to be superposed upon an anthropogenic GHG warming background signal that is emerging strongly in the Arctic [Kaufmann et al., 2009; Serreze et al., 200ice appear most pronounced in the Atlantic sector, such that the pan-Arctic signal may be substantially smaller [e.g., Polyakov et al., 2003; Mahajan et al., 2011]; (2) the sea - ice records synthesized here represent primarily the cold season (winter — spring), whereas the satellite record clearly shows losses primarily in summer, suggesting that other processes and feedback are important;

While worries about rising sea levels are focused on the massive ice sheets of Greenland and Antarctica, the loss of small mountain glaciers comes with its own consequences.

The loss of sea ice coverage is expected to negatively impact its annual migration and winter survival while projected heavier snowfall could reduce the suitability of nest sites.

Satellite pictures (below) clearly show that the recent loss of winter Arctic ice has occurred along the pathway by which warmer waters enter the Barents Sea, deep inside the Arctic Circle, while simultaneously air temperatures far to the south remain cold enough to maintain a frozen Hudson Bay.

The subpolar sea ice loss is mostly in the Sea of Okhotsk and Bering Sea, while the polar sea ice loss is mostly in the Barents - Kara Seas region (Fig. sea ice loss is mostly in the Sea of Okhotsk and Bering Sea, while the polar sea ice loss is mostly in the Barents - Kara Seas region (Fig. Sea of Okhotsk and Bering Sea, while the polar sea ice loss is mostly in the Barents - Kara Seas region (Fig. Sea, while the polar sea ice loss is mostly in the Barents - Kara Seas region (Fig. sea ice loss is mostly in the Barents - Kara Seas region (Fig. 2).
