Potentially fatal combinations of humidity and heat are emerging across the globe

"A new study has identified thousands of incidents of previously rare or unprecedented extreme heat/humidity combinations in parts of Asia, Africa, Australia, South America and North America, including in the U.S. Gulf Coast region.


Most everyone knows that humid heat is harder to handle than the "dry" kind. And recently, some scientists have projected that later in the century, in parts of the tropics and subtropics, warming climate could cause combined heat and humidity to reach levels rarely if ever experienced before by humans. Such conditions would ravage economies, and possibly even surpass the physiological limits of human survival."
