But when you compare it to the 7.3 metres (24 feet) that global sea levels are predicted to rise if the entire Greenland Ice Sheet were to melt away all at once... well, it puts things into perspective.

Greenland is more than twice as large as Texas and if the entire ice sheet melted, scientists estimate global sea levels would rise roughly 24 feet.

What they found was that local destabilization of the Amundsen Sea region of West Antarctica ultimately causes the entire ice sheet to fall into the ocean over several centuries to several thousands of years, gradually adding 3 meters to global sea levels, they report online today in the Proceedings of the National Academy of SciencSea region of West Antarctica ultimately causes the entire ice sheet to fall into the ocean over several centuries to several thousands of years, gradually adding 3 meters to global sea levels, they report online today in the Proceedings of the National Academy of Sciencsea levels, they report online today in the Proceedings of the National Academy of Sciences.

A relatively small amount of melting over a few decades, the authors say, will inexorably lead to the destabilization of the entire ice sheet and the rise of global sea levels by as much as 3 meters.

If global warming leads to an increase in monster storms, MacAyeal adds, then the entire Antarctic ice skirt could be in jeopardy: Larger sea swells could pulverize its huge icebergs and floating ice shelves.

The Greenland ice sheet (GIS) has been melting so slowly and so negligibly in recent decades that the entire ice sheet's total contribution to global sea level rise was a mere 0.39 of a centimeter (0.17 to 0.61 cm) between 1993 and 2010 (Leeson et al, 2017).

Pine Island Glacier could collapse — stagnate and retreat far up into the bay, resulting in rapid sea level rise — within the next few centuries, raising global sea levels by 1.5 m11, 12, out of a total of 3.3 m from the entire West Antarctic Ice Sheet13.

Thus the entire 3 — 4 meters of global sea level contained in that ice sheet may be vulnerable to rapid disintegration, although arguments for stability of even this marine ice sheet have been made [94].

Having said that, it is a really small effect — if the entire Arctic summer sea ice pack melted (average thickness 2 metres, density ~ 920 kg / m3, area 3 × 10 ^ 6 km ^ 2 (0.8 % total ocean area) = > a 4.5 cm rise instantly which implies a global sea level rise of 0.36 mm.

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

Were Greenland's entire ice sheet to melt, global sea level could rise by a startling 7 meters (23 feet), inundating most of the world's coastal cities.

The Greenland ice sheet (GIS) has been melting so slowly and so negligibly in recent decades that the entire ice sheet's total contribution to global sea level rise was a mere 0.39 of a centimeter (0.17 to 0.61 cm) between 1993 and 2010 (Leeson et al, 2017).

That little word of caution will of course be totally ignored by the media who will jump on the «catastrophic acceleration» of global sea levels «on the heels» the imminent «collapse» the entire Antarctic ice shelf, due in 200 years.

«Global Sea ice trend by year only (barely) crosses 95 % significance when the first two months of satellite data is included for the entire record.»

To expand the coverage of global gridded reanalyses, the 20th Century Reanalysis Project is an effort led by PSD and the CIRES at the University of Colorado to produce a reanalysis dataset spanning the entire twentieth century, assimilating only surface observations of synoptic pressure, monthly sea surface temperature and sea ice distribution.

Arctic sea ice loss can be an example of a tipping point, but it's primarily a tipping point for nothing else than itself (i.e., Arctic sea ice loss, and associated ecological systems, etc)-- but without much impact on the energy budget of the entire planet or on global climate sensitivity.

The entire Wilkes Basin would change from ice sheet to ice shelf, bringing along that 3 - 4 metres of global sea level rise.

This has already begun to make a measureable difference to global sea levels, and were the entire island to shed its burden of ice — a process that would take a considerable time − then sea levels would rise by seven metres or more.
