The probability that 2021 will be one of the ten warmest years since records began is already more than 99 percent, according to the US climate agency.
Washington – Last month was the warmest October in the northern hemisphere since records began in 1880, according to measurements by the US climate agency NOAA.
The average temperature over the land areas of the northern hemisphere would have exceeded that of October 2019 – the previous record holder – by 0.11 degrees Celsius, said the NOAA (National Oceanic and Atmospheric Administration).
Worldwide, it was the fourth warmest October since records began, according to NOAA. The average temperature over land and ocean areas was 0.89 degrees Celsius above the 20th century average of 14 degrees. Only in 2015, 2018 and 2019 were October even warmer worldwide.
The probability that 2021 will be one of the ten warmest years since records began is already more than 99 percent, NOAA said. At the end of October, the World Weather Organization WMO announced that, according to preliminary measurements, the year 2021 was probably not quite as hot as the past three years, but that nothing had changed in the long-term trend of significant warming. 2021 will be one of the seven warmest years in recent history – all since 2015. dpa
