Future heat waves may make Persian Gulf region temperatures too hot to be inhabited by humans, suggests a study blaming climate change and published in the journal Nature Climate Change on Monday.

The climate model examined in the study found that heatwaves happening once every 10 to 20 years would eclipse the capacity for healthy human beings to keep normal body temperatures, according to Agence France-Presse.

"We project using an ensemble of high-resolution regional climate model simulations that extremes of wet-bulb temperature in the region around the Arabian Gulf are likely to approach and exceed this critical threshold under the business-as-usual scenario of future greenhouse gas concentrations," said the study led by Jeremy Pal at Loyola Marymount University in Los Angeles,

"Our results expose a specific regional hotspot where climate change, in the absence of significant mitigation, is likely to severely impact human habitability in the future." 

According to Smithsonian.com, heatwaves are already taking their toll. More than 2,500 people died in India earlier this year after temperatures topped the 118.4-degree mark. At that temperature, humans can suffer heatstroke, leaving the elderly particularly vulnerable.

"The new study thus shows that the threats to human health (from climate change) may be more severe than previously thought, and may occur in the current century," said Christoph Schar of the Institute for Atmospheric and Climate Science in Zurich, referring to the study.

AFP said outdoor events like the Muslim pilgrimage known as the Hajj could threaten its participants because of the heat. Predicted temperatures in Mecca and nearby Jeddah would still be risky even though the research suggest those areas would not have the highest temperatures in the region.

Five Middle East cites — Doha in Qatar, Abu Dhabi and Dubai in the United Arab Emirates, Dhahran in Saudi Arabia and Bandar Abbas in Iran — would reach the dangerous "wet-bulb" threshold by 2100, said Smithsonian.com.

"Our results suggest that the … threshold will be breached along much of the Persian Gulf on average once every 10 to 20 years or so at the end of the century," Pal said last week at a news conference.
