2021 Russian wildfires
Smoke from wildfires in Siberia is detected in the Geographic North Pole for the first time in recorded history, according to NASA. The space agency says that as of August 6 "most of Russia" is covered in smoke, while Russia's weather monitoring institute Rosgidromet says that the situation "continues to deteriorate" in the far-eastern Sakha region with around 3.4 million hectares (8.4 million acres) of land currently on fire.
