|UN says extreme heat is the new normal
The United Nations weather agency has warned that extreme temperatures are "the new normal". Scientists say climate change is making heatwaves longer, hotter and more frequent. Many countries have been experiencing record hot weather in the past week. In parts of the USA and China, the mercury went over 50ºC (122ºF). In Death Valley, California, it was 53.9ºC; and in Xinjiang, China, it got up to 52.2ºC. In Spain and Italy, the temperature rose to 46ºC. Many European countries and Japan have issued heat alerts. They advised people to stay in the shade and drink plenty of water. The U.N. weather agency has warned Europe's heatwave could continue for another month.
