«When we look forward several decades, climate models predict such profound loss of Arctic sea ice that there's little doubt this will negatively affect polar bears throughout much of their range, because of their critical dependence on sea ice,» said Kristin Laidre, a researcher at the University of Washington's Polar Science Center in Seattle and co-author of a study on projections of the global polar bear population.

After two decades of rapid ice loss, concerns are arising over how much more ice will be lost to the ocean in the future.

While some earlier studies, using different approaches, have posited that Antarctic ice sheets could add as much as a metre to sea levels by 2100, this new evidence suggests ice loss on this scale is «implausible», the paper says.

The continued swings in the Arctic Oscillation can make it difficult for climate scientists to determine how sea ice loss is altering winter weather, since there is so much natural variability in the system in the first place.

And given that much of this is related to the loss of polar ice, a changing climate would appear to be at least partly — although perhaps not wholly — responsible.

However, our probiotics are very much temperature stable with a minimal loss of potency without refrigeration or ice for up to a few weeks, which is perfect for traveling.

For three particular mismatches — sea ice loss rates being much too low in CMIP3, tropical MSU - TMT rising too fast in CMIP5, or the ensemble mean global mean temperatures diverging from HadCRUT4 — it is likely that there are multiple sources of these mismatches across all three categories described above.

So unless the perimeter of the Greenland ice sheet is the exact same thickness as the entire ice sheet (say 3 km on average), an area loss there, of 15 %, will produce a much smaller % volume loss, than say if this area loss were smack dab in the middle of the Greenland ice sheet.

The lag between decreases in sea ice extent during late summer and changes in the mid-latitude atmospheric circulation during other seasons (when the recent loss of sea ice is much smaller) needs to be reconciled with theory.

As so much of the GIS is grounded below sea - level, it seems to me that the key to any possible catastrophic mass loss is the Jacobshavn effect: the ungrounding of the marine front as the ice thins and becomes buoyant.

Much of the recent sea ice loss is attributed to warmer sea surface temperatures with southerly wind anomalies a contributing cause [Francis and Hunter, 2007; Sorteberg and Kvingedal, 2006], with thermodynamic coupling leading to associated increases in atmospheric moisture.»

Most past modeling experiments that investigated the atmospheric response to Arctic change only considered the loss of sea ice, which of course misses much of the effect of Arctic amplification.

I don't know about the «freakout» claim, but I believe Peter Wadhams» ideas / estimates regarding the loss of arctic sea ice are going to prove to be much more accurate than the IPCC estimates that sea ice will be gone by midcentury.

There is a real risk of bigger ice losses and sea - level shifts, but much more work would be needed to clarify the odds, Dr. Abdalati said.

The lag between decreases in sea ice extent during late summer and changes in the mid-latitude atmospheric circulation during other seasons (like autumn and winter, when the recent loss of sea ice is much smaller) have been demonstrated empirically, but have not been captured by existing dynamical models.

However, the idea is simple, and I've talked about this much in many presentations this winter: Take the amount of ice you need to get rid of from Greenland to raise sea level 2 m in the next century, reduce it by your best estimate of the amount that would be removed by surface mass balance losses, and try to push the rest out of the aggregate cross-sectional area of Greenland's marine - based outlet glaciers.

The upshot is that the Arctic is at least as and maybe much more primed for sea ice loss than last year.

There's much more to discuss about the significance of surface melting in relation to Greenland ice loss and — in the end — a rising contribution to the oceans and sea - level rise.

Since the actual loss of ice is similar in magnitude to this figure, I conclude that a 1 watt / sq meter forcing is «big enough» to produce the melting actually seen, whereas geothermal energy is much too small.

Here is what I understand of what they are saying: — In recent years the Arctic has been experiencing much warmer than usual temperatures and unusual loss in sea ice.

So how much do changes in the Arctic atmosphere play a role in the loss of sea - ice volume and the apparent failure of the GCMs to reflect the current volume loss?

The pace of ice loss — both its extent and the amount of the older, thicker ice that survives from summer to summer — has been faster than most models predicted and clearly has, as a result, unnerved some polar researchers by revealing how much is unknown about ice behavior in a warming climate.

The bottom line, Dr. van de Wal said, is that Greenland is still losing much more ice than is being added through snowfall, and more losses will come in a warming world.

That conclusion seems much closer to reality but may be unwelcome in some circles since the implication is that, if true and with SLR now at 3.4 mm / annum, loss of land - based ice must be considerably greater than hitherto reported.

While it's no secret that much of the Antarctic Peninsula is rapidly melting, scientists were disappointed when they recently found that a previously stable region of Antarctica is experiencing rapid ice loss - so much so that it is even affecting Earth's gravity field.

The volume of the ice lost is much less than that from the loss of a comparable area by Jakobshavn because the ice is an order of magnitude thinner.
