A study in the UK claims global warming saves lives. According to the BBC, annual cold-weather mortality fell by 3 percent between 1971-2003 as winters became more mild. And, apparently, we’ve become more adaptable to rising temperatures, thanks more to our willingness to wear more informal clothes, rather than a physiological change.
However, there’s a 1 in 40 chance that a heat wave in southern England by 2012 will kill 3,000 people immediately, and another 3,000 over the course of a summer. The researchers, however, see this is a trade-off for the 20,000 per year who die from the effects of cold weather.
