A new study shows that ash and smoke clouds from Australian wildfires in 2019 and 2020 had far-reaching effects. They created widespread algal blooms in the Southern Ocean, which is thousands of miles downwind to the east. Such blooms can affect local plant life and the ecosystem. The peer-reviewed study was published in Nature.

To tell us more, we welcome Joan Llort, a postdoctoral fellow at Barcelona Supercomputing Center and Weiyi Tang, a postdoctoral research associate at Princeton University.
