At the time of writing, the UK is experiencing a heatwave. But we know what to expect. People go from complaining about the cold to complaining about the heat, newspapers print pictures of people crammed onto Brighton beach and small children jumping into fountains. And then it's all over and we go back to complaining about the rain again.
But hot weather can also be dangerous, even in the UK, with older people the most vulnerable. At the moment there are 2000 excess deaths attributed to summer heat each year. One study estimated that on current trends this would rise to 12,500 by 2080.
And there are parts of the world where extreme heat is even more lethal.
