Smoke from the devastating Australian wildfires of 2019-2020 led to a reduction in ozone levels in the upper atmosphere, but it’s been unclear how. Now, a team proposes that smoke’s particulate matter can enhance the production of ozone depleting chemicals, matching satellite observations during the Australian fires. The results spark concerns that future wildfires, which are set to grow more frequent with ongoing climate change, will undo much of the progress towards restoration of the ozone layer.

Recent global crises have highlighted the fragility of the interconnected systems involved in getting food from farm to fork. However, siloed datasets have made it hard to predict what the exact impacts of these events will be. In a World View for Nature, researcher Zia Mehrabi argues that precise virtual models like those used in the aerospace industry should be developed for food systems. These so-called ‘digital twins’ could inform global food policy before emergencies unfold.
