Susan Solomon, a pioneering scientist known for her work on the link between CFCs and ozone depletion, received the Special Prize for Female Innovators in Hanoi and the Crafoord Prize in Geosciences for her research on atmospheric trace gases. Her research led to the successful Montreal Protocol, which has helped the ozone layer recover, demonstrating how evidence, public understanding, and political will can address global environmental crises. Solomon's book, "Solvable: How We Healed the Earth, and How We Can Do It Again," outlines the structure behind her optimism for solving environmental challenges. She argues that environmental progress follows identifiable conditions, known as the three Ps, and emphasizes the importance of political leadership and credible science in shaping environmental policy. Despite current dangers, she remains optimistic that limiting warming to two degrees is achievable with sustained effort, showing that decline is not irreversible when threats are visible and manageable.
