. Australia’s Black Summer bushfires acted like a volcanic eruption, slightly cooling the globe « JO LEE MAGAZINE

THE SYDNEY MORNING HERALD/Australia’s disastrous 2019-2020 “Black Summer” bushfire season blew so much smoke into the upper atmosphere that it blocked sunlight from reaching Earth’s surface, potentially causing a brief global cooling effect comparable to a moderate volcanic eruption, new research has found.

In late 2019 and early 2020, raging bushfires in south-east Australia spawned a rash of rare fire-induced thunderclouds, known as pyrocumulonimbus clouds, or pyroCbs. This pyroCb “super outbreak”, as scientists are now calling it, injected plumes of smoke into the stratosphere, a layer of the atmosphere that starts about nine miles overhead.
