The Gulf in the Middle East, the heartland of the global oil industry, will suffer heatwaves beyond the limit of human survival if climate change is unchecked, according to a new scientific study.
The extreme heatwaves will affect Abu Dhabi, Dubai, Doha and coastal cities in Iran as well as posing a deadly threat to millions of Hajj pilgrims in Saudi Arabia, when the religious festival falls in the summer. The study shows the extreme heatwaves, more intense than anything ever experienced on Earth, would kick in after 2070 and that the hottest days of today would by then be a near-daily occurrence.
... The new research examined how a combined measure of temperature and humidity, called wet bulb temperature (WBT), would increase if carbon emissions continue on current trends and the world warms by 4C this century.
... The scientists used standard climate computer models to show that the fatal WBT extremes would occur every decade or two after 2070 along most of the Gulf coast, if global warming is not curbed. Using the normal measure of temperature, the study shows 45C would become the usual summer maximum in Gulf cities, with 60C (140F) being seen in places like Kuwait City in some years.
