The UN has said extreme heat is "the new normal". There are more and longer heatwaves. This week, parts of the USA and China were over 50ºC. Death Valley was 53.9ºC and Xinjiang was 52.2ºC. Japan issued a heat alert. It asked people to stay in the shade and drink plenty of water.

The UN said we need to cut greenhouse gas emissions. It said we need to change our lives because heatwaves are "the new normal". They are affecting our health and water supplies. The heat is making people change their travel plans. A woman tried to "escape the heat" by going to Rome, but said it was hotter than Texas.
