«What I like about this paper is it shows the cost,» said Benjamin Horton, an expert on sea - level rise at Rutgers University who did not contribute to the paper.

In the last few decades, glaciers at the edge of the icy continent of Antarctica have been thinning, and research has shown the rate of thinning has accelerated and contributed significantly to sea level rise.

At a global scale, the increased melting of the ice sheet contributes to rising sea level and may impact global ocean circulation patterns through the so - called «thermohaline circulation'that sustains among others, the Gulf Stream, which keeps Europe warm.

«Greenland is probably going to contribute more and faster to sea level rise than predicted by current models,» said Eric Rignot, a glaciologist at NASA's Jet Propulsion Laboratory who studied the glacial flow in a paper in Science last year.

In a paper published January 25 in Science Advances, a team led by WHOI oceanographers Viviane Menezes and Alison Macdonald report that Antarctic Bottom Water (AABW) has freshened at a surprising rate between 2007 and 2016 — a shift that could alter ocean circulation and ultimately contribute to rising sea levels.

Is it too much of a stretch to assume that sea levels will rise faster than currently predicted, largely because many of the factors that contribute to sea levels rising are occurring at faster - than - predicted, and possibly accelerating, rate?

Finally, there is another way how ice sheets can contribute to sea level rise: rather than melting at the surface, they can start to flow more rapidly.

Quantitatively, Vasskog et al. estimate that during this time (the prior interglacial) the GrIS was «probably between ~ 7 and 60 % smaller than at present,» and that that melting contributed to a rise in global sea level of «between 0.5 and 4.2 m.» Thus, in comparing the present interglacial to the past interglacial, atmospheric CO2 concentrations are currently 30 % higher, global temperatures are 1.5 - 2 °C cooler, GrIS volume is from 7 - 67 % larger, and global sea level is at least 0.5 - 4.2 m lower, none of which observations signal catastrophe for the present.

Such an acceleration is of particular concern at the Pine Island Glacier, because, among Antarctic glaciers, it's «the one that's contributing the most to sea level rise.»

Kjær, Kjeldsen and Korsgaard's team shows that the ice sheet «contributed substantially to sea level rise throughout the 20th century, providing at least 25 ± 9.4 millimeters of the total global mean rise,» writes Csatho, an associate professor of geology in UB's College of Arts and Sciences, in her News and Views analysis.

At the onset of the deglaciation, a ~ 500 - year long, glacio - eustatic event may have contributed as much as 10 m to sea level with an average rate of about 20 mm / yr... RSL (relative sea level) records indicate that from ~ 7 to 3 ka, GMSL likely rose 2 to 3 m to near present - day levels.

Melting and weakening in Antarctica occurs mostly at the margins and not in the interior, and what interior melting occurs, refreezes before it can contribute to sea level rise, while melting and weakening on the edge of the continent, contributes directly and immediately to sea level rise.

Land and sea based ice at both poles have melted, and have contributed to global sea level rise.

The rate at which the melting Greenland ice sheet contributed to global sea - level rise more than doubled from 1996 to 2006.2 (See Greenland ice sheet hotspot for more information on sea - level rise.)

Scientists have recently observed major changes in these glaciers: several have broken up at the ocean end (the terminus), and many have doubled the speed at which they are retreating.2, 5 This has meant a major increase in the amount of ice and water they discharge into the ocean, contributing to sea - level rise, which threatens low - lying populations.2, 3,5 Accelerated melting also adds freshwater to the oceans, altering ecosystems and changing ocean circulation and regional weather patterns.7 (See Greenland ice sheet hotspot for more information.)

New evidence suggest that the longest interglacial (the time in between ice ages)-- a warming period, called Marine Isotope Stage 11, more than 400,000 years ago, created nearly complete deglaciation of southern Greenland, thus contributed 4 - 6 meters to global sea level rise at that period.

So, based on these peer reviewed and generally accepted numbers, 20th century sea levels rose at a 25 % slower rate in the second half of the century than the first which, on any reasonable interpretation, contradicts the notion that global temperature increases during the last 50 years contributed to any sea level rise!»

Researchers at NASA and the University of California, Irvine note that these glaciers already contribute significantly to sea level rise, releasing almost as much ice into the ocean annually as the entire Greenland Ice Sheet.

I understand that melting sea ice does not contribute to sea level rise, but the fact that Antarctic sea ice is at record high levels seems inconsistent with proposed rapid melting of Antarctic ice sheets.

From the 1970s to 2000 they were melting at a rate that contributed 0.042 mm to sea level rise each year, but from 2000 to now they have been melting such that they add 0.067 mm to sea level rise.

When these melt at a minimum the portion of the ice above sea level contributes to sea level rise.

Two - Thirds West Antarctic Ice Sheet = 3.3 Meters Sea Level Rise What's more, though it's not likely to disappear entirely, about two - thirds of the West Antarctic Ice Sheet could well melt — at some point past 2100 — alone contributing about 3.3 meters to global sea leveSea Level Rise What's more, though it's not likely to disappear entirely, about two - thirds of the West Antarctic Ice Sheet could well melt — at some point past 2100 — alone contributing about 3.3 meters to global sea levesea levels.

Scientists at this very moment are observing glaciers melting several times faster than before and sea levels rising dangerously fast, contributing to sea level rise and increased extreme weather around the world.
