Not exact matches

As ice melts and shipping becomes easier and at some point, oil drilling in the arctic ocean will probably increase, Having a strong military will benefit Russia.

ocean system is associated with an amplified increase in arctic surface air temperature, downward longwave radiation, and net heat flux.

Ocean levels have fallen, arctic ice has increased, and so on.

Since IPCC (2001) the cryosphere has undergone significant changes, such as the substantial retreat of arctic sea ice, especially in summer; the continued shrinking of mountain glaciers; the decrease in the extent of snow cover and seasonally frozen ground, particularly in spring; the earlier breakup of river and lake ice; and widespread thinning of antarctic ice shelves along the Amundsen Sea coast, indicating increased basal melting due to increased ocean heat fluxes in the cavities below the ice shelves.

I think what Alastair is alluding to is the fact that, say by 2050 when the arctic ocean will conceivably be ice - free in the summer, the atmosphere will have a much higher relative humidity than it has currently because of the open air = water interface, so this will have a magnifying effect beyond just the feedback from increased CO2.

Moreover, the ocean (which has been responsible for absorbing as much as 80 % of anthropogenic emissions) can become saturated, or as temperatures rise in the temperate regions or winds increase in arctic regions and stir up carbon dioxide from below, act as an emitter.

ocean system is associated with an amplified increase in arctic surface air temperature, downward longwave radiation, and net heat flux.

The rise of CO2 from 270ppm to now over 400ppm, the extent of equatorial and sub tropical deforestation, the soot deposits on the polar ice caps, the increase in atmospheric water vapour due to a corresponding increase in ocean temps and changes in ocean currents, the extreme ice albedo currently happening in the arctic etc, etc are all conspiring in tandem to alter the climate as we know it.

Then again, with a big expanse of exposed arctic ocean, you would expect evaporation to increase, so rainfall might be expected to increase north of the confluence of the Polar and Ferrel cells.

1) It seems to me that the key mechanism for any impact must be the changes that increased arctic ocean temperatures will impose on the atmospheric circulation feature known as the Polar Cell, and via this on the Ferrel cell which sits over the mid latitudes.

and how about nasa's recent report of the apparent arctic ocean gyre reversal to clockwise that is underway — that the counterclockwise gyre of the arctic ocean rotation (since 1989) which apparently also been largely responsible for centrifigally pushing arctic ice into warmer waters, speeding melting — should now predictably result in increasing amounts of ice due to the centripetal pull of the ice toward the north pole?

quote loss of sea ice in the arctic leads to increased ocean heat loss to the atmosphere resulting in more snow elsewhere.

Just recently a «scientist» at the German hyper alarmist PIK «found out» that the (temporary) loss of sea ice in the arctic leads to increased ocean heat loss to the atmosphere resulting in more snow elsewhere.

Bob Tisdale says: January 10, 2011 at 3:05 pm Manfred says: «Just recently a «scientist» at the German hyper alarmist PIK «found out» that the (temporary) loss of sea ice in the arctic leads to increased ocean heat loss to the atmosphere resulting in more snow elsewhere.

at some point the ocean temperature will not be warm enough to keep the arctic sea ice melted and the sea ice will increase and halt the cooling.

Sea ice is lost due to increasing ocean heat transport into the arctic and the resulting loss of ice causes the atmosphere to warm.

[2] Expected impacts include a sea level rise up to 6 - 7m, melting permafrost in the arctic regions, large - scale agricultural losses, increased water scarcity, a collapse of the Gulf Stream in the Atlantic Ocean and an increase of extreme weather events such as floods, droughts or devastating storms.

THERE HAS BEEN A WARMING TREND FROM THE 70s THRU THE LATE 90s,... accompanied by other changes tied to a warming trend (record low arctic sea ice extent & thickness, retreating glaciers, retreating snow lines, warming ocean surface temps, increases in sea height, de-alkalinizing oceans).

As 34F ocean below, this would lead to a 5 deg average temp increase in the measurements for the arctic area when in fact the ocean below hasn't warmed.

LIA wasn't GLOBAL cooling; but colder in Europe, north America — because Arctic ocean had less ice cover - > was releasing more heat / was accumulating - > radiating + spreading more coldness — currents were taking that extra coldness to Mexican gulf — then to the Mediterranean — because Sahara was increasing creation of dry heat and evaporating extra water in the Mediterranean — to top up the deficit — gulf stream was faster / that was melting more ice on arctic also as chain reaction — Because Mediterranean doesn't have enough tributaries, to compensate for the evaporation deficit.

For 8 months of the year, reduced arctic sea ice increases heat loss from the Arctic Ocean due to increased convection, conduction, and evaporation and radiation losses.

A different understanding doesn't stop melting in the arctic, droughts, shifting climate zones, increased ocean temps and sea level rise or the need to anticipate changes these realities will FORCE on society, changes that can't be made quickly.

Zhakarov's model is conceptually simple: during periods of high precipitation when winter ice forms readily, summer ice cover increases, the atmosphere cools, the arctic front together with its associated rain belt shifts south so that freshwater input to the Arctic Ocean decreases, and winter ice cover is thicker, has a deeper draft, and so survives better in summer.

As for «melting in the arctic, droughts, shifting climate zones, increased ocean temps and sea level rise», these things have always happened and always will happen, as will their opposites.

which is why you will see an increased trend in arctic ice extent over the next 20 years plus, along with net cooling of the northern hemisphere, though by your account of the oceans sequestration of CO2, ocean acidification will go through the roof at the same time.

One suggestion for the long term cooling is that the arctic ocean has become partially land locked, leading to an ice cap and increasing the Earth's albedo.

Record droughts in many areas of the world, the loss of arctic sea ice — what you see is an increasing trend that is superimposed on annual variablity (no bets on what happens next year, but the five - to - ten year average in global temperatures, sea surface temperatures, ocean heat content — those will increase — and ice sheet volumes, tropical glacier volumes, sea ice extent will decrease.
