Lee County, Florida Climate Change Vulnerability Assessment

This vulnerability assessment identifies significant projected climate changes for Lee County, Florida,  and the anticipated effects of those changes on both natural and man-made systems in the region. The report also identifies potentially critical vulnerabilities that will need to be addressed by adaptation or accommodation in Lee County. It examines the current climate and ongoing climate change in southwest Florida along with five future scenarios of climate change into the year 2100. These scenarios include:

  • a condition that involves a future in which mitigative actions are undertaken to reduce the human influence on climate change (Stanton and Ackerman 2007),
  • a 90% probable future predicted by the Intergovernmental Panel on Climate Change (IPCC 2007b),
  • a 50% probable future predicted by IPCC, 
  • a 5% probable future predicted by the IPCC, and
  • a “very worst” future in which no actions are taken to address climate change (Stanton and Ackerman 2007). This fifth scenario also corresponds with some of the other worst case scenarios postulated by scientists who think the IPCC estimations are under-estimated (USEPA CRE 2008).

Additionally, the assessment introduces a prioritization ranking for vulnerable systems as follows in descending order: Altered Hydrology; Climate Instability/ Storm Severity; Habitat and Species Changes; Geomorphic (Landform) Changes; Sea Level Rise and Water Temperature and Chemistry Changes; Infrastructure Impacts and Land Use Changes; Air Temperature and Chemistry Changes and Human Health; Human Economy; and Variable Risk.
