Think only world is heating up? Our body is hitting close to thermal limits

When the air temperature exceeds 35°C, the body relies on the evaporation of water - mainly through sweating - to keep core temperature at a safe level

I am a scientist who researches climate hazards. This week I have published research on the potential for a catastrophic cyclone-heatwave combo in the global south. Yet over the past few days I have been approached by various media outlets to talk not about that hazard, but about the unfolding UK heatwave and climate change. It is always satisfying to respond to public interest around weather extremes, but there is a danger that key messages about extreme heat globally are not receiving enough airtime.

It is by now very well established that hot extremes are
