further melting could influence summer rainfall in Europe in the years to come.
The study found that

sea ice shifts the jet stream
further south than normal resulting in increased rain during the summer in northwest Europe.
Dr Screen added: «Scientists are eager to understand the
far - flung effects

This kind

of warming already in progress, affect
further sea ice loss in the Arctic and alter shipping access to the Arctic Ocean.
Over all, the pace
of sea - level rise from the resulting
ice loss doesn't go beyond about 1.5 feet per century, Dr. Pollard said in an interview, a
far cry from what was thought possible a couple
of decades ago.
«The ongoing rapid
loss of Arctic

ice — temperature feedbacks have emerged in the Arctic15, increasing the chances
of further rapid warming and

of a warming planet, increasing heat waves, fires, melting
ice caps,
loss of sea ice, species migration and variable rainfall.
A 2008 study found that a period
of abrupt
sea -
ice loss could lead to rapid soil thaw, as
far as 900 miles inland.
Pokrovsky predicts a
further acceleration
of melting
of the thin
ice and in general greater
ice loss compared to his June prediction; this change is based on the increase in the
sea surface temperature (SST) anomalies in the North Atlantic and the presence
of hot air masses over Siberia and the Russian Arctic.
Further, Figure 4 shows a major
loss of sea ice extent through May; contributions to the loss were especially important from the Barents Sea and northern Baffin Bay (Figure

loss were especially important from the Barents
Sea and northern Baffin Bay (Figure
Sea and northern Baffin Bay (Figure 5).
Further, it only took one month
of persistent wind conditions to slow the rate
of sea ice loss, resulting in an increase in 2009
sea ice extent compared to 2007 and 2008.
In this case, the dramatic
loss of sea ice could tip the Arctic Ocean into a permanent, nearly
ice - free state in summer, with repercussions that may extend
far beyond the Arctic.
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.
And the decline has accelerated, becoming
far more dramatic, since about the year 2000, leading to annual average
sea ice loss of around three million square kilometers.
To summarise the arguments presented so
far concerning
ice -
loss in the arctic basin, at least four mechanisms must be recognised: (i) a momentum - induced slowing
of winter
ice formation, (ii) upward heat - flux from anomalously warm Atlantic water through the surface low ‐ salinity layer below the
ice, (iii) wind patterns that cause the export
of anomalous amounts
of drift
ice through the Fram Straits and disperse pack -
ice in the western basin and (iv) the anomalous flux
of warm Bering
Sea water into the eastern Arctic
of the mid 1990s.
Melt
of the Greenland
ice sheet is
further enhanced by a prolonged inflow
of warm, moist air traced back to Arctic
sea ice loss.
However, much
of the evidence put forward thus
far has shown correlations between
sea ice loss and particular weather patterns, but has not revealed the direct physical connections and causation between the two, leading many mainstream climate scientists to be skeptical
of the work so
far.
They determined, however, that this volume had now increased by a
further 3 cubic miles each year, prompted by an acceleration in the rate at which the
ice caps and glaciers are melting.Unlike what many other scientists have said — including, most prominently, NASA's James Hansen (who believes that a rise in 17 inches by 2100 will be mainly precipitated by the melting
of ice sheets)-- the authors
of this study believe that the
loss of ice from glaciers and
ice caps will account for the majority
of the expected rise in
sea levels.
Serreze explained that as
sea ice declines because
of warmer temperatures, the
loss of ice is likely to lead to still -
further ice losses.
Secretary Salazar has so
far defended the Bush - era «threatened» designation, claiming that threats to the species are only
of concern in the future — notwithstanding the fact that polar bears are already drowning and starving as a result
of sea -
ice loss, with many populations declining.
Now the increased
ice loss is going to give us a
sea surface rise
of 32 cm by 2050 and, according to Hansen, the probability
of a
further 4.7 metre rise in the 45 years to 2095.
When a full - depth ocean model is used, something intriguing happens: the
loss of Arctic
sea ice triggers a
far - flung response that mimics climate change itself, including a slowdown
of the Atlantic Meridional Overturning Circulation (AMOC), a build - up
of heat in the tropical oceans over several decades, and a warming
of the atmosphere a few miles above the tropics.
In other words, rapid
loss of sea ice and a warming Arctic will undoubtedly have
far - reaching and serious effects for everyone.
