"What’s considered officially “dangerous heat” in coming decades will likely hit much of the world at least three times more often as climate change worsens, according to a new study.

In much of Earth’s wealthy mid-latitudes, spiking temperatures and humidity that feel like 103 degrees (39.4 degrees Celsius) or higher -- now an occasional summer shock — statistically should happen 20 to 50 times a year by mid-century, said a study Monday in the journal Communications Earth & Environment.

By 2100, that brutal heat index may linger for most of the summer for places like the U.S. Southeast, the study’s author said.

And it’s far worse for the sticky tropics. The study said a heat index considered “extremely dangerous” where the feels-like heat index exceeds 124 degrees (51 degrees Celsius) — now something that rarely happens — will likely strike a tropical belt that includes India one to four weeks a year by century’s end."
