Run the tourists gazing through the urban canyons of Dubai, lie on the beaches of the Red Sea with its impressive coral reefs or go on a pilgrimage to Mecca. But that goes not long after a U.S. study: the region of the Persian Gulf could be almost uninhabitable due to extreme summer temperatures.
In the simulations, the researchers are in the last quarter of the century that exceed 60 ° C temperatures in the summer. Especially the Arab Gulf States and the Iran are affected by this monkey heat. The temperatures in the scenarios are still at 55 ° C on the Red Sea.
Heat Collapses in the Gulf Region Staying outdoors is impossible
“These extreme conditions have serious implications for the rituals of the Hajj, where praying Muslim pilgrims at Mecca in the open from dawn until dusk,” the researchers write. “This ritual held bound outdoors is probably dangerous to health, especially for the many elderly pilgrims, when the Hajj falls in the summer.”
The two scientists focus in their scenarios to the so-called cooling limit temperature, also wet bulb temperature (tf) called. This temperature is the lowest temperature that can be reached through evaporative cooling. So a cooling limit temperature will be achieved, for example, by packing a thermometer in a wet towel.
“From the tf threshold of 35 ° C probably even the healthiest people would endure no more than six hours and suffer hyperthermia”, the researchers believe.
Already, regions of the Persian Gulf approach this value. On the coast and also in Coast-remote desert regions normal temperatures of 50 ° C be exceeded often. Scientists explain this trend that the region is usually clear, the Red Sea and Persian Gulf also take much sunlight, and concentrate heat and moisture in a very thin layer of air. To have the effect that the Persian Gulf caused very quickly heats up by its very shallow water depth of maximum 100 metres joins.
Climate change will cost up to €72 billion per year
Since no later than the end of March last year, the world’s population know that climate change is not a fantasy or an option for the future. Since the IPPC presented its latest report and declared climate change a reality. And the IPPC gave a cost estimate: climate change will cost the world’s population up to €72 billion. per year.
