2 van de warmste plekken op aarde
Jacobabad in Pakistan en Ras al Khaimah, bij Dubai in de Verenigde Arabische Emiraten
De combinatie van hitte en luchtvochtigheid bereikt hier de grenzen van wat het menselijk lichaam kan doorstaan.
Het lichaam kan dan niet zweten en de warmte blijft in het lichaam en dat kan in deze extreme omstandigheden fataal zijn voor het menselijk lichaam.
Its mixture of heat and humidity has made it one of only two places on earth to have now officially passed, albeit briefly, a threshold hotter than the human body can withstand.
With this region of Pakistan along the Indus Valley considered one of the places most vulnerable to climate change in the world, there are fears that Jacobabad's temperatures may increase further, or other cities may join the club.
“The Indus Valley is arguably close to being the number one spot worldwide,” says Tom Matthews, a lecturer in climate science at Loughborough University. “When you look at some of the things to worry about, from water security to extreme heat, it's really the epicentre.”
Jacobabad and Ras al Khaimah, north east of Dubai in the United Arab Emirates, have both temporarily crossed the deadly threshold. The milestone had been surpassed decades ahead of predictions from climate change models.
The researchers examined what are called wet bulb temperatures. These are taken from a thermometer covered in a water-soaked cloth so they take into account both heat and humidity.
Wet bulb thermometer readings are significantly lower than the more familiar dry bulb readings, which do not take humidity into account. Researchers say that at a wet bulb reading of 35C, the body can no longer cool itself by sweating and such a temperature can be fatal in a few hours, even to the fittest people.
