Paleo - climate studies by Glikson and Brook (in prep) indicate sea level rise rates of well over 5 metres per 1 degree C, consistent with these projections.

Given the increased levels of certainty regarding human - induced global warming (from 90 to 95 %), more robust projections on sea - level rise and data on melting of ice sheets, and the «carbon budget» for staying below the 2 °C target, the WGI conclusions together with other AR5 component reports are likely to put more pressure on the UNFCCC parties to deliver by 2015 an ambitious agreement that is capable of preventing dangerous anthropogenic interference with the climate system.

However, cutting emissions significantly affects the role these processes play: Sea level rise projections for a low - emissions scenario, consistent with the goals of the Paris Agreement, are close to unchanged by the inclusion of these mechanisms.

This study links a framework for global and local sea - level rise projections with simulations of two major mechanisms by which climate change can affect the vast Antarctic ice sheet.

All such projections involve assumptions about the future that can not be tested, so the authors spread their bets: they considered a range of scenarios involving crude population growth, levels of economic growth with time, and a series of predictions of sea level rise, as icecaps and glaciers melt, and as the oceans warm and expand according to predictable physical laws.

The new study prompted a lapse into Ciceronian prose from the New York Times and an instant revision to sea level rise projection maps for coastal cities worldwide, with many observers noting that, at current effort levels, humanity is veering dangerously close to the worst - case scenario.

Projections for sea level rise in New York City increase from 11 inches to 21 inches by the 2050s, 18 inches to 39 inches by the 2080s, and, 22 inches to 50 inches, with the worst case of up to six feet, by 2100.

However, the accelerated retreat of glaciers, combined with greater melting of these ice sheets, suggest that earlier projections of sea - level rise over the next century — such as in the 2007 report of the Intergovernmental Panel on Climate Change — are conservative.8, 9

I concluded that the projections of extreme sea level rise are not consistent with plausible physical mechanisms, not supported by the available data, and further, that the AR4 projected range (about 30 - 50 cm by 2100) agreed perfectly with my projections over a wide range of warming scenarios.

Such solecisms throughout the IPCC's assessment reports (including the insertion, after the scientists had completed their final draft, of a table in which four decimal points had been right - shifted so as to multiply tenfold the observed contribution of ice - sheets and glaciers to sea - level rise), combined with a heavy reliance upon computer models unskilled even in short - term projection, with initial values of key variables unmeasurable and unknown, with advancement of multiple, untestable, non-Popper-falsifiable theories, with a quantitative assignment of unduly high statistical confidence levels to non-quantitative statements that are ineluctably subject to very large uncertainties, and, above all, with the now - prolonged failure of TS to rise as predicted (Figures 1, 2), raise questions about the reliability and hence policy - relevance of the IPCC's central projections.

Coupled with the average climate - change — driven rate of sea level rise over these same 25 y of 2.9 mm / y, simple extrapolation of the quadratic implies global mean sea level could rise 65 ± 12 cm by 2100 compared with 2005, roughly in agreement with the Intergovernmental Panel on Climate Change (IPCC) 5th Assessment Report (AR5) model projections.
