MOSCOW, July 14. / TASS /. Russia’s winter season has shrunk by at least seven days due to global warming over the past 25 years, while summers have grown longer by one to three days, Scientific Leader of the Russian Hydrometeorological Research Center Roman Vilfand told TASS on Wednesday.

"Now one can argue that the duration of the winter season <...> is decreasing. Over the past quarter century, it varied from region to region but [it reduced] at least by seven days," the Russian expert stated.

According to Vilfand, Russia’s summer is also changing amid global warming, however, less rapidly. It becomes longer, on average, by one to three days.

The meteorologist also noted that global warming would not result in the absence of spring and autumn in the future.
