Scientists who have repeatedly warned of future lethal conditions of temperature and humidity caused by heatwaves in a world of climate change have grim news: that future has already arrived. They have combed through local records to identify thousands of episodes in which the dangerous combination of high temperatures and high humidity has risen to levels at which humans could not in theory survive for long. These have happened in Asia, Africa, South and North America and Australia. More than a dozen such episodes have already been recorded around the Persian Gulf, a region that – researchers warned years ago – could one day become deadly for outdoor workers.
