According to a study from Florida International University, sea levels near the Florida keys are expected to rise at least seven inches within the next 100 years, submerging nearly 60,000 acres -- in the best case scenario.
"Under the panel's worst-case projection of ocean waters rising 23.2 inches, about 75 percent of the Keys 154,000 acres and nearly 50 percent of its $43 billion property value could become submerged. Consequences also include the loss of habitat for many endangered plants and species, including Key deer.
...The eye-opening projections were presented at a June meeting in Marathon to urge Monroe County Mayor George Neugent, other Keys leaders and residents to develop long-term plans to deal with climate change. Unlike Miami-Dade and Broward counties, the Keys do not have a climate change task force."
