Heat stress:
The ultimate solution to both a heat-stressed body and a heat-stressed planet is the same: prevention

As heat waves increase in severity and/or frequency with increasing global warming, we have no choice but to become more resourceful and creative.

The next time someone says to you how happy they are with global warming because of less snow in the winter or more shipping lanes open in the Arctic, remind them that what comes with less overall snow in the winter is more overall heat (and drought from absent snow-melt) in the summer. Because an increase in global average temperature, which is the definition of global warming, drives both effects.

Curious to know how much of an increase in average global temp you're likely to be subject to in the course of your specific lifetime? Here's an interactive website that will give you a picture of it, based on the year you were born. It uses the University of Oxford's climate data and models.

So how are things going in the US?

According to the US Centers for Disease Control, "more than 600 people die...each year from heat-related illnesses" in the US. In the United States, heat stroke is the single largest weather-related cause of death, and some sources say the loss of life is greater than from all these weather-related events combined: hurricanes, tornadoes, floods, rain, and lightning. On the east coast, "the number of heat-related deaths in Manhattan could approximately double by the 2080s…" On the opposite coast, Washington state’s famously rainy Seattle has broken it's own record for combined heat and lack of rainxx:

A May 2015 New York Times article warns that sometime between 2040 and 2070, the combined effects of population growth in the US sun belt, and global warming, could quadruple the person-days exposure to extreme heat (95 F or above). See the chart-map just below. This was based on a study published the same month in the journal Nature Climate Change. According to the study, models that account for climate change and population growth and movement suggest that extreme heat exposure in the US will increase four to six fold by 2050.

A modeling study found that global warming and demographic shifts toward Sun Belt cities will likely contribute equally to greatly increased exposure of people to extreme heat later this century. The projections are tallied in annual person-days of exposure to extreme heat, comparing the period 1971–2000 to the period 2041–2070. Person-days are calculated by multiplying the number of days when the temperature is expected to hit at least 95 degrees by the number of people who are projected to live in the areas where extreme heat is occurring.

A July 2015 article in Slate online stated that "...the National Oceanic and Atmospheric Administration confirmed that not only was last month the hottest July on record globally, it was also the hottest month on record overall..."

Any records in Europe?
