Not exact matches
There are more, however, including the amount of sunlight an
ice sheet is able to reflect; the larger an
ice sheet, the more sunlight is reflected, but the smaller an
ice sheet, the more ocean there is surrounding the
ice sheet to absorb the sunlight which
in turn heats up the surrounding waters increasing the melt which decreases the
size of the
ice sheet which
in turn... and so goes the cycle.

Then
in 2008, an area the

Ice Sheet.
«They are the
size of the Alps and the birthplace of the Antarctic
ice sheet,» says geophysicist Robin Bell of the Lamont - Doherty Earth Observatory
in New York City.
Even relatively large calving events, where tabular
ice chunks the
size of Manhattan or bigger calve from the seaward front of the shelf, can be considered normal if the
ice sheet is
in overall balance.
A chunk of
ice the
size of downtown Manhattan fell off the Jakobshavn Glacier
in Greenland on August 16, the fastest moving
ice sheet in the world at present.
In contrast, Bierman and colleagues» data provides a record of continuous ice sheet activity over eastern Greenland but can't distinguish whether this was because there was a remnant in East Greenland or whether the ice sheet remained over the whole island, fluctuating in size as the climate warmed and cooled over millions of year

In parts, it's nearly three miles thick, and, with the nearby West Antarctic
Ice Sheet, it blankets an expanse roughly the
size of the United States and Mexico combined.
The melting
in the north could have been triggered «because the
ice sheets had reached such a
size that they had become unstable and were ready to go.»

At the Dome A site
in East Antarctica — roughly the
size of the state of California — the base layer of refrozen
ice accounted for up to half the total thickness of the
ice sheet, and 24 percent of the area covered by
ice.
The Greenland
Ice Sheet covers an area roughly the
size of Mexico and measures up to 3 km thick
in some places.
New research shows that small fluctuations
in the
sizes of
ice sheets during the last
ice age were enough to trigger abrupt climate change.
The
ice sheet has fluctuated
in size since its formation 34 million years ago, but scientists have previously assumed that it had stabilised around 14 million years ago.
«The Greenland
ice sheet as a whole is shrinking, melting and reducing
in size as the result of globally changing air and ocean temperatures and associated changes
in circulation patterns
in both the ocean and atmosphere,» Muenchow said.
What G&T are missing is the linear effect of water vapour accelerating the
ice albedo effect of change
in size of the sea
ice sheets.
Armed with aerial photos that reveal these trimlines, the researchers mapped the past and present
sizes of the
ice sheet in a 3D computer model.
During that time, which can last hundreds to thousands of years, glaciers and
ice sheets expand
in size and depth.
Models of mountain (alpine) glaciers are applied to solve similar problems to those models used for polar
ice sheets, but typically have a higher resolution (a smaller grid
size) and need to consider the effects of steep and often variable bed slopes, and the transverse stresses found
in valley glaciers.
Unlike the great
ice sheet of Antarctica, the Greenland
ice sheet is melting both on its surface and also at outlet glaciers that drain the
ice sheet's mass through deep fjords, where these glaciers extend out into the ocean and often terminate
in dynamic calving fronts, giving up gigaton -
sized icebergs at times.
So, while the specific
size of the
ice sheet was different, the overall conditions are degraded
in ways not likely to have existed
in the past all at the same time.
What G&T are missing is the linear effect of water vapour accelerating the
ice albedo effect of change
in size of the sea
ice sheets.

in Greenland
in the year 982, climate and

ice sheet over an area the
size of California.
News like the disintegration of an
ice shelf the
size of Rhode Island a month ago conjures a vision that a warming world will lead to doom by drowning — not from melting
ice shelves, which like melting
ice in a glass do not change water levels, but from melting
ice sheets sending their fresh water flowing toward the sea.
Part 1 looked at subcap fossil methane seeps
in Alaska; Part 2 provided a perspective for the
size of these seeps
in relation to other natural and human sources; and Part 3 looked at potential methane sources resulting from the withdrawal of glaciers and
ice sheet.
In addition there are slow climate feedbacks, such as changes of
ice sheet size, that occur mainly over centuries and millennia.
Yearly mass loss from Greenland's
ice sheet, which covers an area the
size of Mexico, increased from 50 gigatons
in 1995 - 2000 to more than 200 gigatons
in 2004 - 2008.
They note a period of low eccentricity centered around an very rapid advance of the
ice sheets in Antarctica where they went from 50 % today's
size to 25 % larger.
I consider a rapid > 50 % increase
in Antarctic
ice sheet size while CO2 is higher than current day something of merit and not to be dismissed lightly.

«Third,
in a period when ocean basins were similar to modern,
ice age climate sensitivity to pCO2 changes is underestimated by climate models even when long term changes
in solar forcing and
ice sheet size and distribution are taken into account, implying that internal positive feedbacks are stronger than previously thought.»
Global sea - level was estimated to have been at least 5 metres higher, resulting from a reduction
in size of the Greenland and Antarctic
Ice Sheets.
