There is additional evidence that climate change is advancing more quickly than scientists previously predicted. New research forecasts uninhabitable heat and humidity in the Persian Gulf by the end of this century.
By the end of this century, areas of the Persian Gulf could be hit by waves of heat and humidity so severe that simply being outside for several hours could threaten human life, according to a study published Monday. Because of humanity’s contribution to climate change, the authors wrote, some population centers in the Middle East “are likely to experience temperature levels that are intolerable to humans.”
The paper, published in the journal Nature Climate Change, was written by Jeremy S. Pal of the department of civil engineering and environmental science at Loyola Marymount University in Los Angeles and Elfatih A. B. Eltahir of the Massachusetts Institute of Technology. Previous studies had suggested that such conditions might be reached within 200 years. But the new research, which depends on climate models that focus on regional topography and conditions, foresees a shorter timeline.
Since even today’s heat waves cause premature deaths by the thousands, mainly affecting very young, elderly and infirm people, the more extreme conditions envisioned in the new paper “would probably be intolerable even for the fittest of humans, resulting in hyperthermia” after six hours of exposure.
Steven Sherwood, a researcher whose work in 2010 suggested that parts of the world could become uninhabitable within 200 years if fossil-fuel burning continued unabated, said he saw no reason to doubt the results of the new study…
Still, he said he was startled by the prediction that many cities on the Persian Gulf coast could be essentially uninhabitable by the end of the century for those without air-conditioning. “That is truly shocking,” he wrote in an email exchange, and added that he found it ironic, “given the region’s importance in providing fossil fuels.”
