The collapse of the Champlain Towers South condominium complex in Surfside, Florida, raised questions about how climate change and environmental impacts may cause damage to coastal buildings. Independent structural issues are suspected to be a major factor in the collapse, but scientists and legal researchers posit that environmental factors also played a role. On December 20, 2021, the Environmental Law Institute hosted a panel of experts that explored the climate risks to coastal communities and buildings in Florida, California, and elsewhere. This Dialogue presents a transcript of that discussion, which has been edited for style, clarity, and space considerations.
