The atmosphere and ocean have warmed, snow and ice have diminished, sea level has risen, and concentrations of greenhouse gases have increased. One of the most robust indicators of a warming climate is rising sea level driven by thermal expansion of ocean water and addition of land-based ice-melt to the ocean, however, sea level rise is not evenly distributed around the globe and the response of a coastline is highly dependent on local natural and human settings. This is particularly evident at the southern end of the Florida peninsula where low elevations and exceedingly flat topography provide an ideal setting for encroachment of the sea. Here, we illustrate projected impacts of sea level rise to infrastructure in Everglades, Biscayne and Dry Tortugas National Parks at four time horizons: 2025, 2050, 2075 and 2100, and under two sea level rise scenarios, a low projection and a high projection.
