As Fairfax County finalizes its first-ever plan to address the future effects of climate change, community members can see how the phenomenon already affects them with a newly released interactive map. Launched last week, the climate map depicts heat and flooding data that can be viewed in conjunction with maps of the county’s population and infrastructure, including roads, utilities, and public facilities. The map offers a clear illustration of the heat island effect, showing that average daytime temperatures are higher in more populated and developed areas along major highways, like Tysons, Reston, the Fair Lakes and Fair Oaks area, and the Route 1 corridor.
