The Copernicus Climate Change Service globally said that May was 0.63 ° C warmer than the May average between 1981 and 2010, making it the warmest month in this data record.
The May increase followed a clear trend Copernicus scored over the past year. In the past twelve months to May, global temperatures were 0.7 ° C warmer than average – identical to last year’s high from October 2015 to September 2016.
The report said that Europe in general was slightly cooler than average, but with sharp geographical differences.
The most noticeable rise was in Siberia, the usually freezing area covering most of Russia, which was rising 10 ° C on average.
An environmental group has described the damage as “catastrophic”, and the concentration of pollutants in neighboring waters has already exceeded permissible levels tens of thousands of times, according to the Russian Environmental Agency Rosprirodnadzor.
Two-thirds of Russia sits on permafrost, which rapidly deteriorates, punching places with giant holes.
This comes in the wake of a noticeably warm winter in Russia, which is usually covered with snow at the beginning of the year.
