Copious amounts of smoke aerosols from the 2019–20 bushfires may have contributed to the onset of the rare, triple-dip La Niña.

In a study published in the journal Science Advances, a team of researchers ran climate models with and without bushfire emissions to determine the role the months-long bushfire event played.
