Many studies have already mentioned that seas around the world are rising rapidly due to global warming. If carbon dioxide emissions around the world remain unchecked, rising sea levels will affect millions of lives in America, a new report revealed.

The report led by Benjamin Strauss, researcher from Climate Central in Princeton, and co-authored by Climate Central's Scott Kulp and Anders Levermann of the Potsdam Institute for Climate Impact Research in Germany has been published in the Proceedings of the National Academy of Sciences. The researchers of the report said that carbon dioxide emissions in near future will decide which areas will be affected by rising sea levels, and which places are safe to occupy.

"The analysis, carbon choices determine US cities committed to futures below sea level, turns on a critical number: For every one degree Celsius of warming we should expect 2.3 meters of long-term, eventual sea-level rise, playing out over millennia", according to the researchers. Stefan Rahmstorf, researcher from the Potsdam Institute who was not part of the new report, said the calculations were made by the researchers after a lot of research.

The researchers did not reveal anything about the future speed of sea-level rise, but there are estimates that it will take about 2,000 years for a rise of approximately 2.3 meters. In the report, the researchers mentioned that the speed of sea-level rise depend on carbon emissions. As the West Antarctic ice sheet are melting rapidly, there are high chances that sea-level will rise speedily.

"The potential magnitude of sea-level rise is staggering," said Michael Oppenheimer, a Princeton University climate researcher who is on the board of Climate Central and says he offered comment on a version of the study. "In the short term, it risks serious disruption of life along the coast while in the long term, it could lead to obliteration of a large and priceless amount of our cultural heritage, worldwide."

"If we don't cut emissions," Strauss said, "we're talking about losing American land [that's] home to more people than live in any state, except for California and Texas. Home to more people than the state of Florida and New York."
