Coastal managers are using sea-level-rise data to protect crucial infrastructure.
Scientists have gone ahead and started to map sea-level-rise scenarios in New Jersey, New York City and flood-prone communities along the Gulf of Mexico to help guide local development and planning.
Hansen suggested that a 10-year doubling time was plausible, pointing out that such a doubling time from a base of 1 mm per year ice sheet contribution to sea level in the decade 2005-2015 would lead to a cumulative 5-metre sea-level rise by 2095.
Here Hansen repeats his view, first published in 2007 but widely ignored, that a 5-metre sea-level rise is possible.
So when planning for future coastal flooding, 6 feet or higher isn't far-fetched when combining sea-level rise with high tides and storm surges, Mr. Lathrop said.
So a sea-level rise of three-quarters of a metre this century, which many who study climate think it reasonable to expect, would wipe the country out.
The Security Council this afternoon expressed concern that the possible adverse effects of climate change could, in the long-run, aggravate certain existing threats to international peace and security and that the loss of territory in some States due to sea-level rise, particularly in small low-lying island States, could have possible security implications.
The threat is more evident in heavily populated low-lying areas, and the risk multiplies with prospects of climate change and associated sea-level rise.
This is a known phenomenon that can in principle be calculated and predicted based on a given sea-level rise, by means of the so-called Bruun effect.
Since more than 180 million people around the world could be displaced by higher sea levels, "Credible projections of sea-level rise in the 21st century are essential for devising adaptation or mitigation measures, " wrote NASA's Josh Willis and John Church, of the Tasmania-based Center for Australian Weather Research.
Dangers like desertification and sea-level rise are also expected to hit the energy-intensive kingdom especially hard, making it an example of both the causes and effects of global warming.
Within the plot of the play at least, in one case, the land appeared to be falling rather than the sea-level rising, and in another, both land and sea were rising together, thus disguising the reality of sea-level rise, but within the plot, a university department would lose a lucrative grant if they told the truth.
To be sure, not everyone agrees that climate change will make sea-level rise more pronounced.
Leaders of small island states, which are on the front lines of sea-level rise, were less enthusiastic.
Caribbean faces unique challenges in coping with the climate change, sea-level rise, natural disasters, alleviation of poverty and sustainable development.

If spending on defences remains limited, and the scenarios for sea-level rise through climate change prove correct, conservation of the marshes may acquire more urgency.
Coastal areas are at increasing risk from sea-level rise and storm surge.
FORBES: Guided By Questionable Science, The EPA Seeks To "Necessarily Bankrupt" The People
U.S. coastlines face a variety of natural and manmade threats pollution, invasive species, overdevelopment, sea-level rise, hurricanes yet they remain vital economic hotspots.
The New Jersey Department of Environmental Protection is directing homeowners rebuilding after Sandy to consult with FEMA's flood maps which don't account for sea-level rise not the Rutgers map.
With coastal development continuing at a rapid pace, society is becoming increasingly vulnerable to sea-level rise and variability as Hurricane Katrina demonstrated in New Orleans in 2005.
Yet that is just what is happening in Greenland, whose relatively warm and wet sheet is on course to melt completely, bringing the prospect of a sea-level rise of perhaps seven metres.
The team has calculated that Alaskan glaciers are responsible for at least 9% of the global sea-level rise during the past century, and Alaska's glaciers raise the level of Earth's oceans by more than one-tenth of a millimetre each year.
"If you extrapolate these results, Greenland is going to be a serious contributor to global sea-level rise" in coming years, said Peter Wadhams, a professor of ocean physics at the University of Cambridge, England, who wasn't involved in the Science study.
Overleaf, we follow the fortunes of Homo sapiens sapiens around the Black and Mediterranean Seas through 30 000 years of a tumultuous history marked by sporadic earthquakes, tsunamis and volcanic eruptions, as well as more insidious hazards tied to a changing climate, such as flooding from glacier melt, gradual sea-level rise or prolonged drought.
This means that we can expect more than the one-meter sea level rise projected for 2100, a fact that the rapid melting of the Greenland ice sheet, as well as strong indications that the western part of the Antarctic ice sheet is also melting, strongly support.
That leaves a maximum six or seven inches of sea level rise remaining from human-induced warming (probably less), which is pretty small beer.
FORBES: It's the Holiday Season, and Global Warming Hype Is Filling the Air
They cite the example of the Philippines, where policymakers are wringing their hands about a possible gradual climate-change-mediated rise in sea level from 1 to 3 millimeters per year while ignoring the primary cause of enhanced flood risk.
They also want the UN to monitor and assess losses, and to find new approaches for addressing loss and damage, particularly for slow-onset events like, say, sea level rise.
In a non-linear problem, the most relevant number for projecting sea level rise is the doubling time for the rate of mass loss.
