 For those living in New York City, the city from which I am melting to you at this very moment, New Yorkers have the worst average increase in temperature of 9.7 degrees. These high temperatures can create health risks. According to the National Weather Service, more deaths were attributed to heat waves last year than any other type of natural disaster like floods or tornadoes. And heat stroke, one of the deadliest illnesses caused by high temperatures, can happen in just a few minutes.
