"Air conditioning, where affordable, is part of the answer. If powered by renewable energy, it is not bad for the climate, and it can save lives. A study in the Lancet concluded that there were 345,000 heat-related deaths worldwide in 2019 among the over-65s, and that the toll would have been 50% higher without air conditioning. So environmentalists are wrong to shun this wonderful technology. Since the organisers of the Paris Olympics decided not to install air conditioners in athletes’ quarters, many teams will simply bring their own."
