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.

�Our results expose a specific regional hotspot where climate change, in the absence of significant [carbon cuts], is likely to severely impact human habitability in the future,� said Prof Jeremy Pal and Prof Elfatih Eltahir, both at the Massachusetts Institute of Technology,�writing in the journal Nature Climate Change.

They said the future climate for many locations in the Gulf would be like today�s extreme climate in the desert of�Northern Afar, on the African side of the Red Sea, where there are no permanent human settlements at all. But the research also showed that cutting greenhouse gas emissions now could avoid this fate.
