The Epic Scale Of Siberia's Wildfires
Images taken by NASA on July 23 show a plume of smoke (top right) above central Siberia that is bigger than most countries.
On July 20, clear skies over Italy (bottom left) give an idea of the scale of the plume.

On July 23, near the city of Krasnoyarsk, the sun set behind a forest shrouded in smoke from the wildfires. The Russian authorities are at odds with Greenpeace over the scale of the current fires.
Russia's official estimate that 4,150 square kilometers of forest have been burned is less than a tenth of Greenpeace's estimate.
The current fires have not caused any direct fatalities, but on July 1 a firefighting plane tasked with dousing blazes in the Irkutsk region crashed, killing all 10 occupants. Russian media reported that the plane was flying at its "minimum permissible height" before the crash.
