The impact on human health should be a key consideration in climate change action, with emerging threats to our physical well-being set to continue as the planet warms. Global experts have sounded the alarm ahead of Cop28 in Dubai as the convention prepares to host the first-ever health day dedicated to solutions to mitigate the impact of environmental change. It is not just the extreme weather events caused by climate disruption that are exposing human vulnerability, but also the myriad associated health threats and the capacity of nations to respond. Tropical diseases, heat exhaustion and chronic kidney disease are just some of the new health challenges posed by a changing climate. (Nick Webster)
