Ensemble decadal prediction simulations using the Community Earth System Model (CESM) can skillfully predict past decadal rates of Atlantic winter sea
ice change because they do well at predicting THC - driven ocean heat content change in the vicinity of the winter sea ice edge in the Labrador, Greenland, Irminger, and Barents Seas.
Not exact matches

ice - cream; when they give you a hug from out of the blue and whisper in your ear «you're the best!»
You can skip roasting the strawberries if you like and just use jam in the center instead, but I beg you not to

ice — the ratio of 26Al to 10Be in the rocks

change is important not only
because of the potential sea level rise locked up in the vast Antarctic
ice sheet, but also the shift in the westerly winds has moved rainfall away from southern Australia.

changing Greenland
ice sheet plays in supplying nutrients to the Arctic Ocean,» observed Eran Hood of the University of Alaska Southeast in Juneau, who studies the meltwater from coastal glaciers in Alaska, and was not involved in the new study.

ice cover declined, the amount of [photosynthesis] increased,» says biological oceanographer Kevin Arrigo of Stanford University's School of Earth Sciences, who led an effort to use the MODIS (Moderate Resolution Imaging Spectroradiometer) devices on NASA's Terra and Aqua satellites to determine
changes in phytoplankton growth.
The study stops short of attributing California's latest drought to
changes in Arctic sea
ice, partly
because there are other phenomena that play a role, like warm sea surface temperatures and
changes to the Pacific Decadal Oscillation, an atmospheric climate pattern that typically shifts every 20 to 30 years.
However, the Intergovernmental Panel on Climate
Change warned in its latest report that this could be an underestimate,
because the computer models used may not be able to predict rapid

ice plays the role of relatively inert rock or dirt on Pluto
because it's usually too cold to
change form into liquid or vapor.

changed their habits
because of different ocean conditions brought on by sea

But that could soon
change, Rignot said,
because the rate at which
ice sheets are losing mass is increasing three times faster than the rate of
ice loss from mountain glaciers and
ice caps.

because of climate and habitat
changes associated with the developing
ice age.
Leaving aside the collapse of the Larsen - B
ice shelf and other
ice shelves in Antarctica, is it too simplistic to expect that dramatic
changes should be anticipated first in the Arctic
because it is sea covered by a few meters of sea
ice and therefore more susceptible to
change, in comparison to Antarctica (which is obviously land covered by glacial
ice up to several kilometers thick in places)?

change would favor the chinstrap penguin,
because this species prefers sea waters without

ice the
change in water vapour will be catastrophic,
because it produces a positve feedback.

change, I usually try to address the specific topics they are questioning (sea
ice, temp record, etc.)
because they may be getting some misinformation from out in web land.
It is important to regard the LGM studies as just one set of points in the cloud yielded by other climate sensitivity estimates, but the LGM has been a frequent target

ice sheet extent, vegetation
changes etc..
If a spike in temperatures due to CO2 causes a non-reversible
change in
ice cover, you have a situation more analogous to a deglaciation
because you now have a forcing that has a strong effect on the equilibrium amount of CO2 in the atmosphere.
We call this the Charney climate sensitivity,
because it is essentially the case considered by Charney (1979), in which water vapor, clouds and sea
ice were allowed to
change in response to climate
change, but GHG (greenhouse gas) amounts,
ice sheet area, sea level and vegetation distributions were taken as specified boundary conditions.
The differences are that the UVic model has a smaller forcing from the
ice sheets, possibly
because of an insufficiently steep lapse rate (5ºC / km instead of a steeper value that would be more typical of dryer polar regions), and also a smaller
change from increased dust.
That's simply
because in climate history, warm climate means small
ice sheets, cold climate comes with big
ice sheets, and sea level has
changed accordingly.
I'm frustrated
because a year ago, pasta, cookies, white bread, french fries and
ice cream were all staples in my diet so I feel any
change from here will be minor.
ICE is dying and is in the last throws of life Electric cars whether you like it or not or whether it will be Tesla leading the charge (sic) or not are now reaching a tipping point

changed the way I regard normal
ice cars.
NPR has always struck me as fairly balanced in that they always give both sides of the story, no matter how nutty or fucking ridiculous the other side is (like those who still believe abortions cause cancer, climate
change isn't real
because there's still
ice in the oceans, etc).
Because they feed in Arctic and subarctic benthic environments, gray whales are thought to be relatively sensitive to
changes in climate, and climatic events such as the Medieval Warm Period (ca. 900 — 1200 AD) or Little

because of the significant influence of sea
ice on the climate system, it seems that high priority should be given to developing ways for reconstructing high - resolution (in space and time) sea -
ice extent for past climate -
change events.
Regional variations arise
because the Earth's gravity field is affected in multiple ways by the melt of
ice, due to the direct effect of surface mass
changes (the gravity field is determined by the distribution of mass), the consequent deformation of the Solid Earth (removing a load causes the Earth's surface to rebound, which in turn
changes the distribution of the Earth's mass), the consequent redistribution of ocean water (the ocean surface is shaped by the gravity filed) and perturbations of the Earth's rotation axis (
because of mass redistribution).
Leaving aside the collapse of the Larsen - B
ice shelf and other
ice shelves in Antarctica, is it too simplistic to expect that dramatic
changes should be anticipated first in the Arctic
because it is sea covered by a few meters of sea

That's simply
because in climate history, warm climate means small
ice sheets, cold climate comes with big
ice sheets, and sea level has
changed accordingly.

More ground turns from white reflective snow to black, heat absorbant dirt.The same effect occurs as sea
ice is lost.The corals blanch, and, as I stated last year on this site, the shutdown of the north Atlantic current will occur, since the salinity level studies I spoke of last year, off Greenland, continue to show that the upwelling mechanisms driving the North Atlanic current are in severe jeapordy,
because the
change in salinity levels effects the driver of the current, the upwelling and downwelling of different salinity levels off Greenland.
