Sentences with phrase «raise sea level an estimated»

The East Antarctic Ice Sheet locks away enough water to raise sea level an estimated 53 meters (174 feet), more than any other ice sheet on the planet.

Not exact matches

And even though these coastal glaciers have passed the point of no return, the researchers predict it's unlikely they'll melt entirely until 2100 — when that happens it's estimated that it will raise global sea levels by around 3.8 cm (1.5 inches).

Complementary analyses of the surface mass balance of Greenland (Tedesco et al, 2011) also show that 2010 was a record year for melt area extent... Extrapolating these melt rates forward to 2050, «the cumulative loss could raise sea level by 15 cm by 2050 ″ for a total of 32 cm (adding in 8 cm from glacial ice caps and 9 cm from thermal expansion)- a number very close to the best estimate of Vermeer & Rahmstorf (2009), derived by linking the observed rate of sea level rise to the observed warming.

Any reforms to come from the process, starting next week, would affect about 62 percent of New York state's population, the proportion estimated to reside now in areas that could be hard hit as rising land and ocean temperatures raise average sea levels around the globe.

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.

If all of the currently attainable carbon resources [estimated to be between 8500 and 13.600 GtC (4)-RSB- were burned, the Antarctic Ice Sheet would lose most of its mass, raising global sea level by more than 50 m. For the 125 GtC as well as the 500, 800, 2500, and 5000 GtC scenarios, the ice - covered area is depicted in white (ice - free bedrock in brown).

Some estimates suggest that if Antarctica's ice sheet melts completely, it would raise sea levels by over 200 feet — enough to flood the planet's land masses.

The USGS, in one estimate, has stated that a total collapse of both the Greenland and Antarctic ice sheets could potentially raise eustatic sea - level 260 feet.

If the entire West Antarctic Ice Sheet were to disintegrate, estimates suggest it could raise global sea levels by 3.3 to 6 meters.

If — or more likely when — Thwaites and its neighbour, the Pine Island glacier, ultimately lose all their ice, one estimate suggests that could raise global sea levels by about 3.4 m, enough to affect every coastal city on Earth.

The Obama administration recently raised its estimate of the economic damage caused by carbon emissions by two - thirds, reflecting an improved understanding among independent experts of the impact of rising sea levels and other developments relating to climate change.

Climatologist Richard Alley, who assisted with some of the initial preparation of the DeConto study, said that while Hansen and his colleagues raised the possibility that sea level rise may far exceed previous estimates, DeConto and his co-author, David Pollard, «have taken a major step forward» in showing specifically how that might happen.

In its most recent estimates on sea - level rise, the United Nations Intergovernmental Panel on Climate Change reported in 2007 that warming ice sheets and glaciers could raise sea levels from 20 to 50 centimeters (about eight to 20 inches) by 2100.

Current total ice - loss in Greenland is running at an estimated 200 Gte / yr and Antarctica at 150 Gte / yr (with ice mass gain in the east and loss in the west — with some estimates of a net gain)-- at that rate of 1mm / yr, by 2100 the global ice - loss would raise sea level by a little over 3 inches.

Consider, for example, that Lowe, et al. [in Avoiding Dangerous Climate Change, H.J. Schellnhuber et al. (eds), Cambridge University Press, Cambridge, 2006, p. 32 - 33], based on a «pessimistic, but plausible, scenario in which atmospheric carbon dioxide concentrations were stabilised at four times pre-industrial levels,» estimated that a collapse of the Greenland Ice Sheet would over the next 1,000 years raise sea level by 2.3 meters (with a peak rate of 0.5 mm / yr).

If currents carried the warm water beneath this ice, it potentially could trigger the collapse of an ice sheet that scientists estimate holds enough water to raise the sea level five meters.

This is estimated to be raising sea levels by 3 millimetres every year.
