In an article entitled,The impact of global warming on health and mortality, published in the Southern Medical Journal in 2004, W.R. Keatinge and G.C. Donaldson of Queen Marys School of Medicine and Dentistry at the University of London note:
Cold-related deaths are far more numerous than heat-related deaths in the United States, Europe, and almost all countries outside the tropics, and almost all of them are due to common illnesses that are increased by cold.
From 1979 to 1997, extreme cold killed roughly twice as many Americans as heat waves, according to Indur Goklany of the U.S. Department of the Interior, Singer and Avery write.Cold spells, in other words, are twice as dangerous to our health as hot weather.
