Japan could experience once-in-a-century heatwaves every year if global warming spirals out of control, according to a warning from the country’s meteorological agency.
A report released on Wednesday indicated that the frequency of “centennial extreme temperatures” – hot days previously recorded only once per century – would occur 99 times per century in Japan if the global average temperature rises by 4 degrees Celsius. Under this scenario, these extreme temperatures would be nearly 6 degrees higher than pre-industrial levels.
