The more the ice cap melts, the more methane is released into the atmosphere, and the more the climate warms. This phenomenon causes sea levels to rise, which is particularly problematic along the flat Florida coastline, where a 1-foot rise in sea level could cause anywhere from 10 to 100 feet of shoreline retreat..
All this seeping methane causes more melting ice, said Chanton oceanographer at Florida State University, which causes sea levels to rise and could affect coastal real estate values, sooner rather than later.
How soon? Possibly over the next 50 to 100 years.
