That's very blatantly false. And it's going to get a lot worse if the planet continues to heat up.

2003 heat wave "In France, 14,802 heat-related deaths (mostly among the elderly) occurred during the heat wave, according to the French National Institute of Health."

NYT 2003: "The staggering number of deaths in France -- perhaps 5,000 by the government's estimate but possibly more than twice that ... The victims were generally found inside apartments, houses and hotels. In virtually every case, there was no air-conditioner."
