Global heating affects fertility, immunity and behaviour – often with lethal results – and the problems are getting worse
Sweating, headaches, fatigue, dehydration – the ways heat exhaustion affects the human body are well documented. As temperatures inch up year by year we need to change the way we live, creating cooler places that provide refuge from heat.
But what about wildlife? We know mass die-offs are becoming more common as heatwaves sweep terrestrial and marine ecosystems, but incremental increases in temperature, which are much harder to study, are harming almost all populations on our planet.
