Heat Waves Are Becoming More Frequent & Enduring

PHOENIX (AP) — Heat waves like the one that engulfed parts of parts of the South and Midwest and killed more than a dozen people are becoming more common. Experts say the extreme weather events, which claim more lives than hurricanes and tornados, will likely increase in the future. A heat dome that killed 13 people in Texas and another in Louisiana pushed eastward Thursday and is expected to be centered over the mid-South by the weekend. Heat index levels of up to 112 degrees are forecast in parts of Florida over the next few days and extreme heat is expected in Arizona by Saturday. Climate scientists say extreme heat deaths will increase without more action to combat climate change.
