People in Jacksonville, FL are especially likely to experience increased risks from heat, precipitation, and flood.

Jacksonville faces with the combined threat of flooding, fires, storm damage and heat waves. The city is the most populous in Florida, with more than 900,000 residents.

The St. Johns River running through the downtown of Jacksonville poses a severe threat to the center of the city from floods and sea level rise. Additionally, land along the Eastern Seaboard is sinking slowly, increasing the relative rate of sea level rise in Jacksonville further. Even the areas of Jacksonville that are not directly affected by water-related climate risks could still be harmed by the economic fallout of a damaged downtown area.

Fire risk depends on proximity to vegation: densely developed urban areas have a much lower risk of burning than areas adjacent to wildland. Climate change increases risks from wildfire by creating hotter, drier conditions for fires to spread. ClimateCheck ratings of fire risk are based on projected weather conditions and U.S. Forest Service models simulating fire behavior.

The Lower St, Johns watershed, which contains Jacksonville, FL, has experienced 592 weeks (52% of weeks) since 2000 with some of its area in drought of any level, and 102 weeks (9% of weeks) since 2000 with some of its area in Extreme or Exceptional drought. Source: National Drought Monitor.
