The new work goes well beyond an increasingly dated consensus finding of the international scientific community on sea level, which stated that it could increase by nearly 1 meter by the year 2100, under a worst - case scenario version of global warming.

In addition to running climate models, the researchers compared modern warming to similar temperature increases that happened approximately 120,000 years ago in a period known as the Eemian, when global sea level was 5 to 9 meters (between 16 and 30 feet) higher than it is today due to the release of glacial water.

This period, known as the «last deglaciation,» included episodes of abrupt climate change, such as the Bølling warming [~ 14.7 — 14.5 ka], when Northern Hemisphere temperatures increased by 4 — 5 °C in just a few decades [Lea et al., 2003; Buizert et al., 2014], coinciding with a 12 — 22 m sea level rise in less than 340 years [5.3 meters per century](Meltwater Pulse 1a (MWP1a)-RRB-[Deschamps et al., 2012].»

The Intergovernmental Panel on Climate Change predicts almost a meter rise in sea level by the end of this century and warns of increased storm surges.

A glacier the size of California in East Antarctica is in danger of melting away, which could lead to an extreme thaw increases sea levels by about 11.5 feet (3.5 meters) worldwide if the glacier vanishes, a new study finds.

A jump of this kind was, however, predicted with sea level rise by end of this Century expected to hit between 0.5 and 1 meters of increase in the IPCC measure and between 5 and 6 feet in US Coast Guard studies (most studies find a range between 3 - 9 feet for this Century).

For example, a recent ice sheet model sensitivity study finds that incorporating the physical processes of hydrofracturing of ice and ice cliff failure increases their calculated sea level rise from 2 meters to 17 meters and reduces the potential time for West Antarctic collapse to decadal time scales.

A policymaker will take this as meaning that sea level rise is probably going to be less than a meter even if CO2 increases to 936 ppm, in other words, policymakers will take this «objective stuff» as serious, reliable estimates of what to expect.
