The mangrove infiltration signals a change in an ecosystem unlike any other in the world and has the potential to alter South Florida's water supply. That's just the beginning, say some scientists and climate experts. Imagine outdoor living in a climate that feels like 120 degrees. Rising seas may cause greater storm surges from hurricanes. The strength of a hurricane could increase by 5 to 10 percent as a result of global warming, says Chris Landsea, a meterologist with the National Hurricane Center.
Hurricanes are a chief cause of beach erosion and mangrove destruction.
Of the state's 825 miles of sandy beaches, more than 435 miles are under siege, with 328 miles critically eroded, according to a state study. Some Florida beaches may disappear altogether. Tax dollars have been used for many years to pump sand back on the beaches but the relatively inexpensive offshore supplies are exhausted for Miami-Dade County, say beach managers in the Department of Environmental Protection. Broward is projected to deplete its offshore sand supply within 15 years, a state report notes. I can foresee that happening.
