At least one-fifth of all homes in seven U.S. cities could be submerged in the next 40 years, according to an analysis of new data on climate change due to carbon emissions.

The cities are:

Metairie, La.

Hollywood, Fla.

Huntington Beach, Calif.

Hialeah, Fla.

Stockton, Calif.

New Orleans, La.

St. Petersburg, Fla.

The cities have a 50 percent chance of sea levels rising between 1 and 3 feet by 2020, and a 1 in 6 chance of sea levels rising between 3 and 10 feet by 2050. At least 866,000 residents in 419,000 homes in these cities could be displaced by 2050 from a combination of rising ocean levels, storm surge and tides.
