Over the weekend, the temperature in central Tokyo rose above 35C, while the city of Isesaki, northwest of the capital, saw a record 40.2C. That was the highest temperature ever recorded in June for Japan. June marks the start of summer in Japan, with temperatures typically staying below 30C during the month. Japan’s government has urged people in Tokyo and its surrounding area to use less electricity on Monday, as it warned that supplies will be strained as the country faces a heatwave. Can the heat wave be attributed to climate change ?
