Joughin's and Tulaczyk's paper, published in Science in 2002, documents an increase in ice mass for one region of the WAIS called the Ross Sea Sector.

The findings suggest that the Indo - Pacific area would see a 40 per cent increase in fisheries catches at 1.5 C warming versus 3.5 C. Meanwhile the Arctic region would have a greater influx of fish under the 3.5 C scenario but would also lose more sea ice and face pressure to expand fisheries.

Something that goes along with this change in atmospheric circulation is reduced sea ice in the region (while sea ice in Antarctica has been increasing on average, there have been significant declines off the West Antarctic coast for the last 25 years, and probably longer).

In the long term, changes in sea level were of minor importance to rainfall patterns in north western Sumatra With the end of the last Ice Age came rising temperatures and melting polar ice sheets, which were accompanied by an increase in rainfall around Indonesia and many other regions of the worldIn the long term, changes in sea level were of minor importance to rainfall patterns in north western Sumatra With the end of the last Ice Age came rising temperatures and melting polar ice sheets, which were accompanied by an increase in rainfall around Indonesia and many other regions of the worldin sea level were of minor importance to rainfall patterns in north western Sumatra With the end of the last Ice Age came rising temperatures and melting polar ice sheets, which were accompanied by an increase in rainfall around Indonesia and many other regions of the worldin north western Sumatra With the end of the last Ice Age came rising temperatures and melting polar ice sheets, which were accompanied by an increase in rainfall around Indonesia and many other regions of the worlIce Age came rising temperatures and melting polar ice sheets, which were accompanied by an increase in rainfall around Indonesia and many other regions of the worlice sheets, which were accompanied by an increase in rainfall around Indonesia and many other regions of the worldin rainfall around Indonesia and many other regions of the world..

When the Arctic sea ice goes the increase in water vapour in the Arctic region will accelerate the Greenland melt.

Greenland as an high altitude inlandsis seems to be very special compared to these regions, and probably has more inertia towards meting, as the center isolated from sea influence and accumulate ice form increasing precipitations.I don't really remenber what models predict in Greenland, but it doesn't confuse me if the response is not temporally and geographically the same as other regions.

The Antarctic ice increase is occurring in a limited region near the Ross Sea, and is related to the ozone hole through a fairly complicated change in atmospheric dynamics.

So, the positive feedback between melt and velocities implies that more melt leads to higher velocities, which bring in more ice from cold regions to warm regions which increases the melt and hence the velocity etc, with as a final result a rapid loss of ice and hence an enhanced increased sea level.

Australian Antarctic Division glaciology program head Ian Allison said sea ice losses in west Antarctica over the past 30 years had been more than offset by increases in the Ross Sea region, just one sector of east Antarctisea ice losses in west Antarctica over the past 30 years had been more than offset by increases in the Ross Sea region, just one sector of east AntarctiSea region, just one sector of east Antarctica.

Moreover, the increase in atmospheric water vapor content in the Arctic region during late autumn and winter driven locally by the reduction of sea ice provides enhanced moisture sources, supporting increased heavy snowfall in Europe during early winter, and the northeastern and mid-west United States during winter.

A good point as arctic regions that are hit with warmer water streams will prevent sea ice extent while those with colder ones can massivly increase in volume when the air is cold enough though no growth would be visible from the top down view.

Sea ice melt is creating an opening for new commercial opportunities in the region, including increased ship traffic.

So an increased GHG effect should manifest in the polar regions in a decrease in winter sea ice extent and a smaller increase in summer sea ice extent relative to the winter maximum extent (ie a smaller annual range in sea ice extent).

Further investigation of ice thickness and free ice drift conditions, in addition to persistence of SLP maxima, will provide further insight as to whether convergence (divergence) of sea ice associated with SLP highs (lows) will give rise to increased ice retreat in the Arctic and the Beaufort Sea region in particulsea ice associated with SLP highs (lows) will give rise to increased ice retreat in the Arctic and the Beaufort Sea region in particulSea region in particular.

While the overall sea ice extent in the Southern Ocean has not changed markedly in recent decades, there have been increases in oceanic temperatures and large regional decreases in winter sea ice extent and duration in the western Antarctic Peninsula region of West Antarctica and the islands of the Scotia Arc.

(b) A more vigorous atmospheric circulation in the region of the Norwegian Sea would explain the observed facts, namely the recession of the ice - limit, the increased frequency of south - westerly winds, rather than south - easterly, in North Norway, and the consequent marked rise in winter temperatures which has attained its greatest magnitude in the north of the Scandinavian Peninsula.

Climate change is the long - term average of a region's weather events lumped together.There are some effects of greenhouse gases and global warming: melting of ice caps, rising sea levels, change in climatic patterns, spread diseases, economic consequences, increased droughts and heat waves.

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 -

For example, reductions in seasonal sea ice cover and higher surface temperatures may open up new habitat in polar regions for some important fish species, such as cod, herring, and pollock.128 However, continued presence of cold bottom - water temperatures on the Alaskan continental shelf could limit northward migration into the northern Bering Sea and Chukchi Sea off northwestern Alaska.129, 130 In addition, warming may cause reductions in the abundance of some species, such as pollock, in their current ranges in the Bering Sea131and reduce the health of juvenile sockeye salmon, potentially resulting in decreased overwinter survival.132 If ocean warming continues, it is unlikely that current fishing pressure on pollock can be sustained.133 Higher temperatures are also likely to increase the frequency of early Chinook salmon migrations, making management of the fishery by multiple user groups more challenging.1in seasonal sea ice cover and higher surface temperatures may open up new habitat in polar regions for some important fish species, such as cod, herring, and pollock.128 However, continued presence of cold bottom -

Population increase of polar bears on Svalbard and decrease in sea - ice cover in the Arctic region during summer probably results in more frequent interactions with reindeer on the archipelago.

As the Arctic sea ice melts, the water vapor delivered into the the atmosphere increases in the polar region, and so does the snowfall, so that the whole thing starts over again.

Moreover, significant trends in sensible heat and evaporation rates are evident in satellite - derived datasets, especially in the Barents - Kara Sea region in the fall due to increases in the air - sea temperature and humidity gradients, collocated with reductions in sea iSea region in the fall due to increases in the air - sea temperature and humidity gradients, collocated with reductions in sea isea temperature and humidity gradients, collocated with reductions in sea isea ice.

The amount of detrital petrological tracers transported by icebergs and deposited in the ice - rafted debris belt (an Atlantic region between 40 - 50 ° N) greatly increases during episodes of southward and eastward advection of cold surface waters and drift ice from the Nordic and Labrador seas (Bond et al., 2001; figure 48 A).

It is widely recognized that modern Arctic region sea ice concentrations are considerably more advanced today than they were a few thousand years ago, with most studied regions showing the increase in sea ice extent occurring «over the last centuries».

The sea ice loss - related increase in open water north of Siberia can contribute to increased fall snowfall in that region.

Model studies suggest that a collapse of the AMOC could lead to a reduction in surface air temperature of around 1 - 3 °C in the North Atlantic region and surrounding land masses, but with local cooling of up to 8 °C in areas of increased sea ice (Vellinga and Wood, 2002; Vellinga et al 2002; Manabe and Stouffer; 1997; Jacob et al 2005).

Moreover, the increase in atmospheric water vapor content in the Arctic region during late autumn and winter driven locally by the reduction of sea ice provides enhanced moisture sources, supporting increased heavy snowfall in Europe during early winter and the northeastern and midwestern United States during winter.

B) Arctic sea ice maximums do have a near - physical limit: The Arctic Ocean shores limit sea ice once the region ices over, and any increase in maximum must occur in very, very small regions down the east and west shores of Greenland, in the narrow gap between Asia and North American continents, etc..

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.
