At a high-end scenario for greenhouse gas emissions, a team of researchers write in the influential medical journal The Lancet, fewer and fewer major cities will be able to host a Summer Olympics as the end of the century nears. The reason? Too much risk of seeing weather conditions get so hot and humid that they would pose a major heat illness danger to athletes.

Everyone from health officials to utilities companies are offering advice on how to weather the heat wave the end of this week.

As we hit high-heat season in the Northern Hemisphere, it is useful to clarify tactics that can be used to help maintain healthy body temperatures. These tips are not commonly known and can be adopted by anyone, anywhere.

“This may be one of the worst heat waves in the last few decades,” the National Weather Service warned.

If you’ve ever dreamed of flying, the place to go this weekend was Minnesota. Several days of 90-plus-degree heat buckled roads across the state, launching speeding vehicles toward the horizon like the Dukes of Hazzard.
