He suggested that blobs of warmer ice would gradually float up and break through the shell, creating the soaring domes on the surface.

But the models also suggest that the scheme could go too far: Adding excess sulfur could increase ice in Antarctica, «overcompensating» for warming, says Rasch, which could affect ecosystems and the global ocean - atmosphere system in a myriad of ways that scientists haven't studied.

And, worryingly, the research suggests that as these glaciers melt and retreat backward, the shape of the seabed will continue to expose many of them to warm ocean water for hundreds of miles as the ice moves inland.

Over the last few years, research has increasingly suggested that ice loss in this region is heavily driven by the influence of the warming ocean.

The findings suggest that the Indo - Pacific area would see a 40 per cent increase in fisheries catches at 1.5 C warming versus 3.5 C. Meanwhile the Arctic region would have a greater influx of fish under the 3.5 C scenario but would also lose more sea ice and face pressure to expand fisheries.

Previous research suggested that rapidly warming air and sea temperatures — which melt sea ice — might cause their numbers to plummet by as much as 19 % by 2100.

But an ice core collected in nearby Greenland suggests that the planet experienced continuous cold from 40,000 to about 115,000 years ago, when the last warm interglacial period ended, Miller said.

Two new studies suggest that during ice ages, steep drops in temperature may have sent ancient species moving to warmer areas.

From 1992 to 2003, the decadal ocean heat content changes (blue), along with the contributions from melting glaciers, ice sheets, and sea ice and small contributions from land and atmosphere warming, suggest a total warming (red) for the planet of 0.6 ± 0.2 W / m2 (95 % error bars).

The sinking slab submerges into Europa's interior and combines with warmer interior ice, the researchers suggest.

The new Hansen paper suggests that warmer water at the ice grounding lines matters more in Antarctica, and less on Greenland.

«suggesting that Arctic warming will continue to greatly exceed the global average over the coming century, with concomitant reductions in terrestrial ice masses and, consequently, an increasing rate of sea level rise.»

When you say «If the oceans are warming at all, or if the net ice melting is positive, we are not in equilibrium» it suggests that you see temperatures inexorably rising towards an equilibrium.

Our findings support a previous study suggesting that the impact of anthropogenic climate warming on Arctic sea ice became detectable from the early 1990s onwards (19).

[Response 2: The comment suggests that ice ages and global warming have the same cause.

In the first place, the evidence suggests that the Ice Age warmings were local, not global, and were counterbalanced by cooling in the other hemisphere.

Qualitative indicators like sea ice coverage, spring thaw dates, and melting permafrost provide strong additional evidence that trends have been positive at middle and high northern latitudes, while glacier retreat suggests warming aloft at lower latitudes.

Re 9 wili — I know of a paper suggesting, as I recall, that enhanced «backradiation» (downward radiation reaching the surface emitted by the air / clouds) contributed more to Arctic amplification specifically in the cold part of the year (just to be clear, backradiation should generally increase with any warming (aside from greenhouse feedbacks) and more so with a warming due to an increase in the greenhouse effect (including feedbacks like water vapor and, if positive, clouds, though regional changes in water vapor and clouds can go against the global trend); otherwise it was always my understanding that the albedo feedback was key (while sea ice decreases so far have been more a summer phenomenon (when it would be warmer to begin with), the heat capacity of the sea prevents much temperature response, but there is a greater build up of heat from the albedo feedback, and this is released in the cold part of the year when ice forms later or would have formed or would have been thicker; the seasonal effect of reduced winter snow cover decreasing at those latitudes which still recieve sunlight in the winter would not be so delayed).

If, for example, scientists had somehow underestimated the climate change between Medieval times and the Little Ice Age, or other natural climate changes, without corresponding errors in the estimated size of the causes of the changes, that would suggest stronger amplifying feedbacks and larger future warming from rising greenhouse gases than originally estimated.

• Dynamical processes related to ice flow not included in current models but suggested by recent observations could increase the vulnerability of the ice sheets to warming, increasing future sea level rise.

They predict that the cooling from the medieval warming and the little ice age was approximately 0.2 K. Moberg reconstruction suggests that such a cooling is 0.6 / 0.7 K, that is three times larger: this is a lot.

Should the ice sheet start to melt in a serious way (i.e. much more significantly than current indications suggest), then lowering of the elevation of the ice sheet will induce more melting simply because of the effect of the lapse rate (air being warmer closer to sea level due to pressure effects).
