It's crucial to stay cool in hot weather as it can have serious effects on your health (see further down this page). Here we round up some of what we have learned. Over the years, BBC Future has covered many different aspects of living with and enduring extreme hot weather. In the US, an estimated 1,600 people die each year due to extreme heat while it can also place considerable strain on health services. ( Learn more about how the heat dome is causing record temperatures.) The energy grid in Texas has also struggled under the strain of surging air conditioning use. Temperatures have reached more than 119F (48C) and millions of people have been issued with excessive heat warnings. The " heat dome" causing a record heatwave this summer in the southern US, including Texas and Louisana, has been made five times more likely due to human-induced climate change, according to one analsysis.
While there is still a great deal of uncertainty about toll that heatwaves take (the World Health Organization estimates 166,000 people died between 19, by comparison), there is little doubt that the number of people exposed to heatwaves around the world is increasing.Īnd climate change is only likely to make heatwaves more frequent and intense in the future. In 2019, extreme heat is estimated to have caused the deaths of 356,000 people worldwide, according to one set of estimates, making it one of the most dangerous yet overlooked natural hazards. The oppressive temperatures of a heatwave can have far-reaching impacts, from risks to human health to destroying crops and increasing the risk of wildfires.
