A World Meteorological Organization (WMO) senior extreme heat expert has warned of the heart attack risk as heatwaves intensify due to climate change at a regular UN news conference in Geneva on Tuesday, 18 July.<br /><br />John Nairn said: “These events will continue to grow in intensity and the world needs to prepare for more intense heatwaves.<br /><br />“So repeated high nighttime temperatures are particularly dangerous for human health because the body is unable to recover from sustained heat. This leads to increased cases of heart attacks and death.”<br /><br />The UN weather agency said that temperatures above 40C were forecast to persist not only in the Mediterranean, but across North America, Asia and North Africa.
