Potentially fatal bouts of heat and humidity on the rise, study finds

Scientists identify thousands of extreme events, suggesting stark warnings about global heating are already coming to pass, Guardian,  Nina Lakhani 9 May 2020 Intolerable bouts of extreme humidity and heat which could threaten human survival are on the rise across the world, suggesting that worst-case scenario warnings about the consequences of global heating are already occurring, a new study has revealed.Scientists have identified thousands of previously undetected outbreaks of the deadly weather combination in parts of Asia, Africa, Australia, South America and North America, including several hotspots along the US Gulf coast.

Humidity is more dangerous than dry heat alone because it impairs sweating – the body’s life-saving natural cooling system.

The number of potentially fatal humidity and heat events doubled between 1979 and 2017, and are increasing in both frequency and intensity, according to the study published in Science Advances.……

The ominous findings come as something of a surprise to scientists, as previous studies had projected such extreme weather events would occur later in the century, mostly in parts of the tropics and subtropics where humidity is already a problem. …..  https://www.theguardian.com/environment/2020/may/08/climate-change-global-heating-extreme-heat-humidity
