Weatherman summed up in 2017
Expiring 2017 was the warmest in the history of Russia. While forecasters did not take into account performance in December, but they are unlikely to change the situation. The first month of winter was accompanied by a warming in most parts of the country.
For example, this December, the thermometer showed indices higher even than last year. But 2016 was also a record hot for Russia.
Meteorologists attribute the extreme weather to global warming.
