How large of a role has ocean warming been playing in the rapid loss of
sea ice volume there?
This emphasizes that over the last 5 million years, we've also seen an increase in the size of the fluctuations of
global ice volume.
At that point,
ice volume on land is still advancing and the cold time will be similar to a little ice age.
Perhaps this mechanism contributes to acceleration in
ice volume loss between 1979 and the present.
To notice something is going on with the world's ice sheets, you could measure melting water runoff, glacier retreat or use satellites and GPS to
measure ice volume decline.
Is there any correction to account for surface heat instead of surface T by considering the
melted ice volume?
Ice extent, she said, will exhibit considerable variability even after the arrival of ice - free summers,
whereas ice volume trends would be more consistent.
These records provide both a direct measure of sea level and an indirect measure of
global ice volume.
A change
in ice volume one day leads to a change in the same direction in the next day.
As one can see, there's about 2000 cubic kilometers (2 trillion cubic meters)
more ice volume than there was a year earlier and in 2016.
From my position of somebody who has studied the Arctic for many years and has been actively participating in submarine measurements of the Arctic ice thickness since 1976, it seems extraordinary to me that for Prof. Slingo can effectively rule out these PIOMAS data in her consideration of the evidence for
decreasing ice volume, when one considers the vast effort and diligence that has been invested....»
But he also noted, «There is some indication from the QuickScat data that 2nd and 3rd year ice has increased somewhat in the past couple of years which may imply not so linear decline of
arctic ice volume.»
The most important of these occurred during the latest Miocene (t = ∼ 5 m.y. ago)
when ice volumes increased beyond those of the present day.
If one takes the simple view that deglaciation is forced by only global
ice volume change and greenhouse feedbacks, then one would be forced to conclude that Antarctic temperature change led all of its forcings!
Scientific observations show that in the Arctic, warming temperatures have led to a 75 % loss in sea
ice volume since the 1980s, and recent reports suggest the Arctic Ocean will be nearly free of summer sea ice by 2050, said Sullivan.
In the last decades, the maximum summer melt is around 21,000 km3, but practically the same anount refreezes in winter (the Arctic
winter ice volume has a smaller decline than summer ice).
