00:39 Sea Level Rise Threatens Trump’s Real Estate Rising seas could mean Trump’s Mar-A-Lago estate could soon be under water.

At a Glance Trump's "Winter White House" is one of his many real estate holdings threatened by rising sea levels.

Water is expected to completely cover many of Florida’s barrier islands by the end of the century.

One has to wonder if President Donald Trump realizes that pulling out of the Paris climate agreement could very well accelerate damage to his family's real estate empire in the not-so-distant future.

Much of Trump's holdings are located in low-lying areas of Florida, including his Mar-a-Lago estate and Doral golf course. He and millions of other Floridians' properties are threatened by rising seas in the not-so-far-off future, according to projections from NOAA and the South Florida Regional Climate Change Compact.

"His properties live off of tourism — golfing communities, places where fat cats go and spend money and hobnob. It’s all related to the tourism economy in South Florida," Jim Cason, the Republican mayor of Coral Gables, told the Associated Press.

Coral Gables is one of many coastal communities in the United States and beyond now bracing and planning for sea-level rise. Already, many coastal areas in the U.S., including Florida, are plagued by unusually high king tides, coastal erosion and storm surge, thanks to climate-driven rising sea levels.

"If the beaches are gone or the streets are flooded, it's going to affect the value of his property," Cason noted. "So as a prudent businessman, he ought to conclude that the science is right and we need to prepare and plan."

Palm Beach Commissioner Steven Abrams told the Sun-Sentinel Trump, who has said in the past that climate change is a hoax perpetrated by the Chinese, should seriously consider the risks to his prized waterfront property.

"Even though he's president, Mar-a-Lago is not invulnerable to sea level rise," Abrams said.

Trump faces a similar problem in Hawaii, where he owns the Trump International Hotel and Tower in Waikiki Beach. In Ireland, a golf course owned by the president faces the same predicament. And did we mention his properties in Vancouver, Canada; Panama City, Panama; Uruguay and Mumbai, India?

The U.N. Intergovernmental Panel on Climate Change said by 2100, 26 major U.S. cities will face an "emerging flooding crisis ." The threat is particularly heightened during storms. Sea levels have already risen about 8 inches compared to pre-industrial times, and that rise has helped boost the surge and flooding damage during tropical storms and hurricanes .

As sea levels rise as predicted — some 2 to 3 feet, or more, within this century — Trump’s 123-room Mar-a-Lago mansion and private club will soon include seawater covering its immaculate lawns.

Water is expected to completely cover many of the state’s barrier islands, especially during storms, at some point this century. Roads leading to Trump's estate on a barrier island would also be affected.

The worst-case scenario calls for a 10- to 12-foot rise in sea levels by 2100, according to a NOAA report released in January. Should the rise go to just 6 feet, 934,000 of Florida's homes, or 12 percent, would be underwater by 2100 , according to Zillow. In Palm Beach, which includes Mar-a-Lago, about 51 percent of homes, a total of $10.9 billion in real estate, would be underwater.

"We’re already in for a sea-level rise that will put all low-lying coastal areas out of business, and that’s using U.S. government projections," Harold Wanless, chairman of the University of Miami’s Department of Geological Science who has studied sea-level rise for decades, told the AP. "At some point in the not-too-distant future, we’ll be leaving Miami ... we’re all moving somewhere."
