A new interactive map has revealed that dozens of American cities could Be under water against 2100 because of the rising sea level.
An international team of researchers estimated that global sea level could rise by a stunning 6.2 feet a year 2100 if the emission of carbon dioxide (CO2) continues to increase.
That is about double the most recent worldwide projection of the United Nations, and the researchers said that this scenario is 'very likely', with a 90 percent chance of becoming a reality if humanity does not considerably reduce emissions.
Researchers discovered that people on the east coast would be struck the most difficult with large parts of New York City, Boston, Atlantic City and Miami.
The map also predicted that the Mar-A-Lago resort of President Donald Trump, based in Palm Beach, Florida, will also be under water in about 75 years.
However, it was predicted that the west coast would see fewer floods, even after scientists have long said that the entire state would eventually be flooded.
“Our new very likely projections emphasize how great the uncertainties are when it comes to an increase at sea level,” said study-chief author Benjamin Grandey, senior researcher at Nanyang Technological University (NTU), Singapore.
'The high -quality projection of [6.2 feet] Underlines the need for decision makers to plan critical infrastructure accordingly. What is even more important, these results emphasize the importance of climate mitigation by reducing greenhouse gas emissions. '

The Coastal Risk Screening Tool from Climate Central has released the card, so that people can see whether their house would be influenced by rising sea level (displayed red).
Climate scientists have monitored the east coast for fear of melting glaciers. And the new card shows that they might have had a good reason.
Important parts of coastal cities such as Philadelphia, Pennsylvania, Charleston, North Carolina, Savannah, Georgia and Miami, Florida would be under water.
Along the Gulf Coast, Mobile, Alabama, New Orleans, Louisiana and Galveston, Texas would usually be flooding as the sea level rises.
On the west coast, large parts of Tacoma, Washington and the San Francisco Bay Area, Huntington Beach and San Diego, California would collapse to the rising waters.
But interesting is that this side of the country would be much less affected by the rise in sea level than the southern and eastern coasts of the US.
Scientists think that this is because the country along the west coast actually rises because of the shifting of tectonic plates, which increases sea level at a slower pace than the national average, according to Sealevelrise.org.
It is not only cities that are threatened. Some iconic parks, nature reserves and nature references can also be deposited into the ocean.
The Coastal Risk screening tool from Climate Central shows the areas all over the world that are the heaviest affected by the rise in sea level, with immersed areas in the red. An increase of 6.2 feet would immerse a lot from New York City
Boston would usually also be under water under this 'very likely' scenario
This includes Everglades National Park in Florida, Atchafalaya Delta Wildlife Management Area in Louisiana, Blackwater National Wildlife Refuge in Maryland and Grizzly Island Wildlife Area in California.
Current sea level projections depend on a series of methods to model climate processes.
For example, some projections contain well -understood phenomena such as melting glaciers.
But others absorb more uncertain events, such as abrupt collapse of ice board.
Miami would also see considerable flood. In the US, people who live on the east coast would be the worst struck by the rise in sea level
Along the Gulf Coast would close rising waters on New Orleans
As a result, these models produce different projections, making it difficult to say with certainty how much sea level will rise over time.
In his IPCC Sixth Assessment Report, released in 2023, the UN estimated that the global sea levels under high emissions scenarios between 1.9 and 3.2 feet would rise.
However, the researchers at NTU and Delft University of Technology (TU Delft) in the Netherlands have chosen a 'Fusion' approach to their estimates by integrating statistical methods with expert judgments.
The west coast will not be hit as hard as the East Coast and the Gulf Coast, but the Bay Area of ​​California would still see a considerable flood
The researchers took a 'fusion' approach to their estimates by integrating statistical methods with expert judgments to give a clearer, more reliable picture of future sea level rise. Displayed is Manhattan, New York after heavy rainfall in September 2023
They claim that this offers a clearer, more reliable picture of future sea level rise.
“Our new approach tackles an important problem in science at sea level: different methods for projecting sea level raising often produce different results,” said Grandey.
“By combining these different approaches in a single merger projection, we can estimate the uncertainty associated with future rise in sea level and quantify the very likely reach of the rise in sea level.”
The researchers hope that the findings will emphasize the urgent need to limit the CO2 emissions and to curb global warming. Displayed is New Orleans, La Na Hurren Katrina, August 2005
The merger model predicts that global sea level under a scenario with low emissions will most likely rise between 0.9 and 3.2 feet at 2100.
But under a scenario with high emissions, the merger model predicts that global sea level is most likely between 1.6 and 6.2 feet.
The researchers published their findings in the journal Earth's Future.
If the most extreme predictions of the scientists are correct and worldwide sea level rise by 6.2 feet, hundreds of coastal cities and cities can be immersed under water.
The researchers hope that the findings will emphasize the urgent need to limit the CO2 emissions and to curb global warming.
Professor Benjamin Horton, director of the Earth Observatory of Singapore at NTU, said: 'This NTU research is a significant breakthrough in science at sea level.
“By estimating the likelihood of the most extreme results, it underlines the serious effects of the rise in sea level at coastal communities, infrastructure and ecosystems, whereby the emphasis is placed on the urgent need to tackle the climate crisis.”
