Sentences with phrase «ice sheet loss due»

Mercer further commented that the loss of ice shelves on the Antarctic Peninsula, as has since been observed, would be an indicator that this process of ice sheet loss due to global warming was underway.

Not exact matches

The new result focuses on ice loss due to a major retreat of an outlet glacier connected to a long «river» of ice — known as an ice stream — that drains ice from the interior of the ice sheet.

His comments are based on the paper «Limits in detecting acceleration of ice sheet mass loss due to climate variability», B. Wouters, J. L. Bamber, M. R. van den Broeke, J. T. M. Lenaerts and I. Sasgen, Nature Geoscience 6, 613 — 616 (2013) doi: 10.1038 / ngeo1874 Find the abstract and illustrations for that paper here.

Under all RCP scenarios the rate of sea level rise will very likely exceed that observed during 1971 — 2010 due to increased ocean warming and increased loss of mass from glaciers and ice sheets.

This is despite using observed ice sheet mass loss (0.19 mm / year) in the «modelled» number in this comparison, otherwise the discrepancy would be even larger — the ice sheet models predict that the ice sheets gain mass due to global warming.

I would also keep in mind the fact that we are only speaking of the short - term Charney Climate Sensitivity, and the long - term climate sensitivity is presumably going to be about twice that — due to ice sheet loss and the like.

At this stage, corresponding to a peak warming of 2 ° to 3 °C, both the West Antarctic Ice Sheet and the Wilkes Basin are experiencing rapid ice loss due to their instability, which manifests itself in a visible threshold in sea - level rise (see ImagIce Sheet and the Wilkes Basin are experiencing rapid ice loss due to their instability, which manifests itself in a visible threshold in sea - level rise (see Imagice loss due to their instability, which manifests itself in a visible threshold in sea - level rise (see Image).

Collecting data from NASA's satellite Gravity and Recovery Climate Experiment, known as GRACE, and GPS measurements of the bedrock on the edges of the ice sheet, the Denmark Technical Institute's National Space Institute in Copenhagen was able to show that crustal uplift due to ice loss has gone up by 1.5 inches between October 2005 and August 2009 along the northwest coast, a change that study co-author John Wahr calls «very dramatic».

«It is very likely that the rate of global mean sea level rise during the 21st century will exceed the rate observed during 1971 — 2010 for all Representative Concentration Pathway (RCP) scenarios due to increases in ocean warming and loss of mass from glaciers and ice sheets.

In draft versions at least, the new IPCC report does tackle the question of ice sheet loss, finding it «very likely» that melting ice and the expansion of the ocean due to its heating will lead to sea - level rise exceeding that of the last century.

Sea level will increase slowly at first,... but as Greenland and West Antarctic ice is softened and lubricated by melt - water and as buttressing ice shelves disappear due to a warming ocean, the balance will tip toward ice loss, thus... causing rapid ice sheet disintegration.

To say nothing of the warming trends also noticed in, for example: * ocean heat content * wasting glaciers * Greenland and West Antarctic ice sheet mass loss * sea level rise due to all of the above * sea surface temperatures * borehole temperatures * troposphere warming (with stratosphere cooling) * Arctic sea ice reductions in volume and extent * permafrost thawing * ecosystem shifts involving plants, animals and insects

Ice - sheet volume is controlled by the balance between mass input and mass loss; mass input is almost entirely due to snowfall, and mass loss is from iceberg calving supplied by flow of the ice sheet, or runoff of melt watIce - sheet volume is controlled by the balance between mass input and mass loss; mass input is almost entirely due to snowfall, and mass loss is from iceberg calving supplied by flow of the ice sheet, or runoff of melt watice sheet, or runoff of melt water.

As explained in the press release, the scientists began with the measure of sea level rise between 2005 and 2013, then deducted the amount of rise due to meltwater (e.g., melting ice sheets and loss of glacier mass worldwide) and then the amount of rise due to the expansion of water from the warming in the upper portion of the world's oceans (which scientists have good data on).

Sea - level rise due to polar ice - sheet mass loss during past warm periods.

But one modeling study put the threshold level for the eventual near - complete loss of Greenland's ice sheet at a local warming of just 2.7 C — which, due to Arctic amplification, means a global warming of only 1.2 C. Total melting of Greenland — luckily, something that would likely take centuries — would raise sea levels by 7 meters, submerging Miami and most of Manhattan, as well as large chunks of London, Shanghai, Bangkok and Mumbai.

«Significant loss of ice from polar ice sheets» Of course, this does not apply to floating ice (with the exception of small changes due to higher temperature and water expansion that might happen incidentally).
