Wildfires on permafrost are ravaging Yakutia - or the Sakha Republic - the largest and coldest entity of the Russian Federation. The scale is mesmerizing. There are some 300 separate fires, now covering 12,140 square kilometers - but only around half of these are being tackled, because they pose a threat to people. The rest are burning unchecked.

Omsk region reported ‘record high’ number of wildfires and cases of dry grass burning, that turn into wildfires this spring, with one day last week counting nearly a thousand new events a day. Omsk region emergency services said the number of wildfires is seven to ten times above the norm.
