Temperatures of 55°C to emerge if global warming continues

Super-heatwaves of 55°C to emerge if global warming continues http://www.enn.com/climate/article/52119  10 Aug 17, Heatwaves amplified by high humidity can reach above 40°C and may occur as often as every two years, leading to serious risks for human health. If global temperatures rise with 4°C, a new super heatwave of 55°C can hit regularly many parts of the world, including Europe.

A recently published study by the Joint Research Centre (JRC) – the European Commission’s science and knowledge service – analyses the interaction between humidity and heat. The novelty of this study is that it looks not only at temperature but also relative humidity to estimate the magnitude and impact of heat waves.

It finds out that the combinations of the two, and the resulting heatwaves, leave ever more people exposed to significant health risks, especially in East Asia and America’s East Coast.

Warm air combined with high humidity can be very dangerous as it prevents the human body from cooling down through sweating, leading to hyperthermia. As a result, if global warming trends continue, many more people are expected to suffer sun strokes, especially in densely populated areas of India, China and the US.  Read more at European Commission, Joint Research Centre (JRC)
