It's been a week of wild weather around the world, with extreme heat in North America, China and in Southern Europe. Some parts of the US and China have exceeded 50C - while parts of Southern Europe face temperatures in the mid-40s.

Temperatures like these are expected to become common during summer months due to our warming climate - but what does 50C heat do to the human body? And can we adapt?

On this week's ClimateCast Tom Heap speaks to science correspondent Thomas Moore who has spent time as a 'guinea pig' in a 50C heat chamber to measure how his body reacted. They're joined by Dr Anna Moore who specialises in how heat impacts the human body and explains why the climate crisis is also a health crisis.
