Climate change means more mosquito days, increasing Zika risk.

Urban Heat Islands

Cities are almost always hotter than the surrounding rural area but global warming takes that heat and makes it worse.

Chattanooga is the 6th fastest-warming city in the U.S.

More than 200,000 people living Tennessee are especially vulnerable to extreme heat.

Currently, Tennessee averages 10 dangerous heat days a year. By 2050, Tennessee is projected to see 55 such days annually (a more than 5-fold increase).

As the planet continues to warm from the increase in greenhouse gases in the atmosphere, the temperatures that we consider to be normal are also rising.

Summers are getting muggier as the dewpoint temperature rises

Tennessee is projected to see an increase in severity of widespread summer drought of approximately 65 percent by 2050.

69 percent of meterological stations in Tennessee are getting more winter precipitation as rain than snow.

Climate Central analysis shows that the number of large fires on Forest Service land is increasing dramatically. 

More than 2.3 million people in Tennessee, or 37 percent of the state's population, are living in areas at an elevated risk of wildfire.

More than 350 million gallons of sewage spilled due to a 48 hour rain event in Memphis in March.

In Tennessee, there are more than 270,000 people living in areas at an elevated risk of inland flooding.

Across most of the country, the heaviest downpours are happening more frequently, delivering a deluge in place of what would have been routine heavy rain. 

According to the National Climate Assessment, the most extreme precipitation events (those in the 99th percentile of intensity) have increased in every region of the contiguous states since the 1950s.
