Heat is the number one weather-related killer. The first heat wave of the season hits the body hard because it takes time to get acclimated to the rise in temperatures. Then, when temperatures don't drop off much at night, it doesn't give the body an opportunity to recover. Another heat related health issue is air quality. As ozone levels continue to rise from greenhouse gas emissions, so do our number of days with poor air quality. This is particularly dangerous to the elderly, children and asthmatics.
Of all weather and climate extremes, heat waves are among the most well-understood consequences of global warming. Studies have shown that global warming made the deadly 2003 European heat wave more likely to occur, as well as the record-shattering 2010 Russian heat wave.
