This is not a week when there was any evidence of global warming in western Siberia, with thermometers plunging to the minus 40s and minus 62 Celsius. Meteorologists say it may get colder still.
At Bolshoe Olkhovskoe oilfield there was a new record for the Khanti-Mansi region with a bone-crushing temperature of minus 62C. The village of Kazym in the same district of Beloyarsky hit minus 58C.

In Tyumen, school classes were cancelled from grades 1 to 9, with minus 36C the trigger for children to stay home, although elsewhere in Siberia - for example Yakutia in recent weeks - students are still expected in school at below minus 52C.
Nizhnevartovsk hit minus 50C, the coldest winter in ten years in the city. School classes were cancelled today - and for the rest of the week.

He told his Vkontakte social media page: 'To me, as a lover of mystery and horror, it seemed that I was in a hodgepodge of movies like 'Something', 'Mist' and 'Silent Hill'.
'I added a warm sweater, an extra pair of socks and one scarf to my suit, and in this outfit went for a walk in the evening in Surgut. My mobile discharged literally 5-10 minutes after I uploaded a video to my Instagram.

Hahaha, it sorta looks like we are going to experience global cooling for a while now. There will be lots of opportunities to be happy, it seems. It will be 2031 before the winters become less severe. After then,we will be back to global warming. Humans and their activities have little to do with it.
