Permafrost is ablaze with hundreds of wildfires in world’s coldest region
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.
