Not exact matches

Now, a new modeling study finds a link between these winters and the decline of sea ice in a part of the Arctic Ocean known as the Barents - Kara sea region, bordering Norway and Russia.

In previously ice - rich areas such as the Beaufort Gyre off the Alaskan coast or the region south of Spitsbergen, the sea ice is considerably thinner now than it normally is during the spring.

Such research is now becoming urgent as regional climate change is already impacting upon areas of West Antarctica and the Antarctic Peninsula [30] and colonies in this region may already be affected by the consequent loss of sea ice [8].

Aside from the fact that 90 degrees north sits in the middle of a 2.5 - mile - deep ocean, that's quite a statement considering two things: first, no one has been routinely monitoring sea ice along both coastlines between then and now, and second, the region was clearly warmer than it is today (in summers) around 8,000 to 10,000 years ago — on both the Siberian and North American sides.

They still think that the Antarctic surface is warming, not cooling like you now believe because of this Hansen paper: «In contrast, the Southern Ocean (specifically the region where Antarctic sea ice forms) has been warming at 0.17 °C per decade.»

Low heights in the Atlantic side suggest colder temperatures and less sea ice export, while north of Siberia winds are now offshore, which may reverse the persistence of sea ice in that region.

Polar bears are one of the most sensitive Arctic marine mammals to climate warming because they spend most of their lives on sea ice.35 Declining sea ice in northern Alaska is associated with smaller bears, probably because of less successful hunting of seals, which are themselves ice - dependent and so are projected to decline with diminishing ice and snow cover.36, 37,38,39 Although bears can give birth to cubs on sea ice, increasing numbers of female bears now come ashore in Alaska in the summer and fall40 and den on land.41 In Hudson Bay, Canada, the most studied population in the Arctic, sea ice is now absent for three weeks longer than just a few decades ago, resulting in less body fat, reduced survival of both the youngest and oldest bears, 42 and a population now estimated to be in decline43 and projected to be in jeopardy.44 Similar polar bear population declines are projected for the Beaufort Sea regionsea ice.35 Declining sea ice in northern Alaska is associated with smaller bears, probably because of less successful hunting of seals, which are themselves ice -

Researchers have now linked the loss of sea ice in the Arctic region, along with an increase in snow cover in northern Asia, to a weaker polar vortex.

«Ice sheets now appear to be contributing modestly to sea level rise because warming has increased mass loss from coastal areas more than warming has increased mass gain from enhanced snowfall in cold central regions,» the report by a team led by Professor Richard Alley of Pennsylvania State University in the US says.

Updated information about ice extent in this region indicates substantial ice retreat in the eastern Barents and the Kara Seas, where ice is now well below climatological extent (Figure 5), with little change in the Greenland Sea and Fram Strait region, where the ice edge is within the decadal mean range except for the southernmost stretches shown in Figure 5.
