The lengthy wildfire season follows a record-hot Arctic summer. People living in Yakutsk are waking up to heavy smog brought from the wildfires raging to the west, east and north; struggling to breathe and with head, eye and throat aches.

Russian weather officials and environmentalists have said climate change is a major factor behind the increase in fires.

Wildfires in Russia have burned across a combined area the size of Greece so far in 2020, surpassing official estimates threefold. Experts warn that this year’s blazes could become the most destructive in history.
