A significant layer of gas that deflects much of the sun’s radiation was disappearing much faster than anyone expected. Projections suggested it would collapse by 2050, increasing skin cancer rates, harming crops, and destroying the marine food chain. The situation was dire. But today, we are on the path to recovery. Dr. Susan Solomon, among other scientists, contributed key findings to understand what was depleting the ozone layer and how to address it. In this video she takes us back to her expedition to Antarctica, breaks down how we managed to fix this huge problem, and looks at our next big environmental challenge — climate change — with the unbridled optimism that drove her to fix the ozone hole.
