According to the Copernicus Climate Change Service, global warming between May 1981 and 2010 was 0.63 degrees Celsius warmer than in May, making it the warmest on record, according to the Copernicus Climate Change Service.
The May increase follows a clear trend recorded by Copernicus compared to last year. Last May, global temperatures were 0.7 degrees Celsius warmer than average – matching the previous year’s long highs between October 2015 and September 2016.
Europe was generally slightly cooler than average, but with sharp geographical differences, the report said.
The deadliest spike was in Siberia, usually the icy region that covered most of Russia, with an average temperature of more than 10 degrees Celsius.
An environmental group described the damage as “catastrophic” and said the concentration of pollutants in nearby waters had already exceeded the approved level by several thousand times, according to the Russian environmental agency Rosprednadzor.
Two-thirds of Russia sat in permafrost, which is rapidly declining, puncturing places including giant synchols.
It has followed a significant warm winter in Russia, which usually becomes snowless at the beginning of a year.
