Killer heat

The recent heat has been record-setting in parts of Florida, and in some unusual ways.

Sunday's high temperature of 98 degrees in Jacksonville tied its daily record for August 11 set in 2011. This is a type of record one would normally expect during a heat wave.

However, high levels of humidity have prevented the mercury from falling as much as it normally does overnight. The morning lows have been so warm, they’ve also broken a few records across the state.

A report released this week predicts a lot more days of extreme heat - so much that they're being called "killer heat" days. We conclude our three-part series with a plea from scientists for politicians to do something - before it's too late.

In 1995, a heat wave killed more than 700 people in Chicago. It affected mostly elderly, African-American women who lived on their own.

A report released this week shows climate change could mean a lot more days of extreme heat for Florida and Tampa Bay, and with it, the likelihood residents will be exposed to significant health risks.
