New study shows Jacksonville is 8 degrees warmer than most of the planet

JACKSONVILLE, Florida. – A new climate study shows many areas of Jacksonville are warmer than the rest of the planet.

This all comes from a group called Climate Central, which has been tracking the Urban Heat Index, which shows that densely populated urban areas are warmer than other places on Earth. The data includes more than 900,000 people living in Jacksonville.

It shows that on average, temperatures in the city are 7.83 degrees warmer. The hottest parts of the city in the study include the northwest part of downtown, a small part of Arlington and the area around NAS Jacksonville.

The study found that about 11,000 of the city’s residents live in an area where the outside temperature is 9 degrees above normal.

This is largely due to the growth of urban areas like downtown, where there is a lot of concrete and people and few trees.

“It’s even worse in the city because it’s coming from cement, buildings, sidewalks and, as you said, people,” said Jen Brady, senior data scientist at Climate Central. “Buses, cars, everything generates heat. Air conditioners generate heat, if you have window air conditioners. So having that concentrated in cities raises it to a whole other level.”

But Jacksonville is not unusual. It is above the planet’s average temperature, but no warmer than most other major U.S. cities.

New York and San Francisco topped the list, while Jacksonville came in only 54th among the hottest major cities.

One thing the study highlighted is what Climate Central calls “red line” neighborhoods. They are often located in inner cities, have larger minority populations, and tend to be warmer.

The group said the cause is often outdated infrastructure and busy highways that cross the area.

News4JAX reached out to the City of Jacksonville for comment on the study. Here is their response:

The Deegan Administration is taking active steps to mitigate the effects of the heat to ensure public safety.

Here’s a snapshot of the many things we’re currently working on.

Both the natural and built environments play a significant role in heat exposure, as well as our ability to cope with extreme heat. We have heat islands in Duval County, with the worst of them being in Urban Core 32206, 32208, 32209, and 32254 (based on data from the HHS Heat-Health Index).

Our resilience, sustainability and health teams are focused on a number of ways to reduce the impact of heatwaves on the community. For example, community cooling centres, playgrounds and community pools across the county are providing people with a much-needed break from the heatwave.

Deegan’s administration is also focused on a long-term strategy to mitigate the effects of heatwaves. It includes a range of measures, such as expanding urban forestry to lower temperatures, as well as installing lighter, more permeable surfaces to reduce heat absorption and lower surface temperatures. Permeable surfaces can significantly reduce the impact of heat islands and can minimize flooding through reduced stormwater runoff, while also preventing overloading of sewer systems.

We are also working on piloting green roofs and green walls on city buildings and other initiatives included in the city’s Resilience Strategy.
