Scientists have estimated that by the end of the century some parts of the Persian Gulf will suffer heatwaves that are too hot for the human body to survive.
By 2100, parts of Qatar, the United Arab Emirates, Saudi Arabia, Bahrain and others will experience combinations of temperature and humidity which make the deadly 2003 heat wave in Europe “look like a refreshing day”.
