Why You Don’t Hear About the Ozone Layer Anymore

Ozone Layer

In the early 80s, scientists located there was a hole in the ozone over the South Pole. A powerful layer of gas that deflects much of the sun’s radiation was fading much quicker than anyone anticipated. Projections indicated it would collapse by 2050, advancing skin cancer rates, harming crops, and killing the marine food chain. The situation was bad and alarming. But today, we are on the path to healing the ozone layer.

Dr. Susan Solomon, with other scientists, contributed key results to understand what was weakening the ozone layer and how to handle it. In this video, she takes us back to her trip to Antarctica, breaks down how we worked to fix this massive problem, and looks at our next major environmental challenge — climate change — with the rampant optimism that forced her to fix the ozone hole.
