Benjamin Strauss of Climate Central in Princeton, N.J., led the research team, which finds that over the coming decades and stretching into millenia, the waters will reclaim large areas of land where people now live. Not only the volume of water melted from ice sheets contributes to the rise, but also the Antarctic and Greenland sheets that have a gravitational pull on the ocean, due to their massive size.

A new study, published on Monday, revealed that if carbon gas emission continue to increase as “business as usual”, sea levels could rise as much as 33 feet by global average.
The research team determined that for every Celsius degree increase in temperature, there would be a corresponding rise of 2.3 meters of sea level over the next 2,000 years.
To bring this issue into focus for the American population, the researchers pinpoint the land at risk which is occupied by over 20 million people. He said that we should imagine chunk of ice in a warm room.
Although a certain degree of inundation is locked in because of historic and current carbon emissions, low-lying areas and their populations could escape the most severe consequences of rising seas if policymakers make radical carbon cuts, the study said.
As a solution, authors of study stated that reducing carbon dioxide emission in the next years to come could mitigate the catastrophic effects of global warming, such as flash flood, drought and starvation. Researchers say that future emissions will determine the areas we can occupy or may have to abandon.
Strauss said that the rise may happen at the start of the next century or it may take several centuries.
Other cities already locked-in include Cambridge, Massachusetts, and Charleston, South Carolina.
Local weather Central, which has beforehand produced a collection of on-line instruments permitting customers to anticipate the native results of local weather change, projected the inhabitants of lots of of cities nationwide that will be displaced by rising sea ranges after 2100 below 4 completely different carbon-emission eventualities.
Using this understanding of the link between warming and eventual ice melt, the authors estimate that with current carbon emissions, the world has likely already committed to 1.6 meters of very long term sea level rise – more than 5 feet.
Asked whether people will take seriously a report that anticipates climate effects taking place a century or more in the future, Love said the current generation should be making plans for its descendants.
Those two cities can’t be saved from climate change and global warming, a new report claims..
They also considered what might happen if the world were to make a big turnaround, reaching peak carbon emissions by 2020.
“The results offer a new way to compare different emissions scenarios or policies and suggest that the long-term viability of hundreds of coastal municipalities and land now inhabited by tens of millions of persons hang in the balance”, the paper says.
New Orleans, the city of jazz, Mardi Gras and voodoo magic, is reportedly already sinking.

“Historic carbon emissions appear already to have put in motion long-term SLR [sea level rise] that will endanger the continuity and legacy of hundreds more municipalities, and so long as emissions continue, the tally will continually increase”, it says.
