Thus, I would suggest that decision makers use these «best - available» distributions but also consider the consequences for their decisions of «worst - case» sea - level rise scenarios (e.g., about 2.5 m globally in the course of the century according to Kopp et al., 2014).

Indeed, the paleoclimate record contains numerous examples of ice sheets yielding sea level rise of several meters per century, with forcings smaller than that of the BAU scenario.

Because of the uncertainties in projected sea level rise over the remainder of this century, Sasmito and his co-authors use both the low and the high sea level rise scenario from the most recent International Panel on Climate Change (IPCC) report (AR5).

Global average sea level is projected to rise by 18 to 59 cm by the end of the 21st century (2090 - 2099), depending on the scenario (Table 3).

In all SRES scenarios, the average rate of sea - level rise during the 21st century very probably exceeds the 1961 to 2003 average rate (1.8 ± 0.5 mm / yr).

While Mörner et al. (2004) suggest that the increased risk of flooding during the 21st century for the Maldives has been overstated, Woodworth (2005) concludes that a rise in sea level of approximately 50 cm during the 21st century remains the most reliable scenario to employ in future studies of the Maldives.

Projected globally averaged sea - level rise at the end of the 21st century (2090 to 2099), relative to 1980 to 1999 for the six SRES scenarios, ranges from 0.19 to 0.58 m (Meehl et al., 2007).

«The high end of the unchecked pollution scenario would threaten the homes of hundreds of millions with chronic flooding or permanent submergence this century,» said Ben Strauss, a sea - level rise expert with Climate Central.

Under the IPCC Business As Usual emissions scenario, an average rate of global mean sea level rise of about 6 cm per decade over the next century (with an uncertainty range of 3 — 10 cm per decade).

«A semi-empirical approach to projecting future sea - level rise» «Testing the robustness of semi-empirical sea level projections» «Kinematic constraints on glacier contributions to 21st - century sea - level rise» «Contribution of Antarctica to past and future sea level rise» «Global sea level rise scenarios for the United States National Climate Assessment» «Reconstructing sea level from paleo and projected temperatures 200 to 2100AD» «Global sea level linked to global temperature» «Upper limit for sea level projections by 2100»

«It is very likely that the rate of global mean sea level rise during the 21st century will exceed the rate observed during 1971 — 2010 for all Representative Concentration Pathway (RCP) scenarios due to increases in ocean warming and loss of mass from glaciers and ice sheets.

In my opinion, if emissions follow a business - as - usual scenario, sea level rise of at least two meters is likely within a century.

Projections of global mean sea level rise over the 21st century, based on different emissions scenarios.

Under the worst - case scenario investigated, if pollution continues unabated, and if seas respond to ongoing warming by rising at the fastest rates considered likely, sea levels could rise more than 4 feet this century alone, wiping out coastal infrastructure and driving communities inland.

«It is very likely that the rate of global mean sea level rise during the 21st century will exceed the rate observed during 1971 — 2010 for all RCP scenarios... with a rate of rise 8 — 15 mm yr — 1 over the last decade of the 21st century) for RCP8.5.»

In the meantime perhaps you might like to remind readers of the sea levels scenario Hansen predicted for the end of the century and might then like to calculate the exponential rise needed to attain it.

If all the ice on Greenland were to melt, it would raise sea level by 7 meters (23 feet), but even under a high temperature rise scenario, it could take many centuries for it to melt completely.

Beyond the 21st century, sea level rise depends strongly on the emissions scenario.

«By the end of this century, global sea level is expected to rise by more than 2 feet in a low emissions scenario or nearly 3.5 feet in a higher emissions scenario.

These projections indicate that, depending on ice melt scenarios, the Mid-Hudson's sea level could rise from between two and six feet by the end of the century.

And sea level rise, just build your house somewhere else, there will still be plenty of room for everyone's houses, and the number of houses we will build in the next century for quite a variety of reasons will dwarf the number of houses we'd have to build to move everyone out of the way even in the worst possible scenarios.

There is enough information now, in my opinion, to make it a near certainty that IPCC BAU climate forcing scenarios would lead to a disastrous multi-meter sea level rise on the century timescale.

This inertia is also the reason for the relatively small difference in sea - level rise by 2100 between the highest and lowest emissions scenario (the ranges even overlap)-- the major difference will only be seen in the 22nd century.

«You should be aware, though, that in 2100 there will not just be a «new sea level» but more importantly a rapidly rising sea level — at the highest end of the IPCC scenarios at a rate of 16 cm per decade, which is about equal to what we had in the 20 th Century — not per decade but for the whole cCentury — not per decade but for the whole centurycentury.

[Response: You should be aware, though, that in 2100 there will not just be a «new sea level» but more importantly a rapidly rising sea level — at the highest end of the IPCC scenarios at a rate of 16 cm per decade, which is about equal to what we had in the 20 th Century — not per decade but for the whole cCentury — not per decade but for the whole centurycentury.

However, according to the IPCC AR5, the average rate of global sea level rise over the 21st Century will very likely exceed that observed during 1971 - 2010 for a range of future emission scenarios.

All of these things point to a precarious future for our species — a business - as - usual scenario will mean some six feet of sea level rise and some regions of the world becoming uninhabitable or disappearing under rising seas by the end of the century.
