On December 12, 2015, nearly 200 countries created a major new agreement on climate change, accompanied by national commitments to act. The Paris Agreement has rightly been celebrated as a breakthrough, but was unquestionably constrained by the need for compromise, and its details will continue to be developed at the international, national, and local levels. On January 9, 2016, a panel of expert commentators and delegation members from a variety of national jurisdictions convened at the annual American Association of Law Schools meeting to analyze the Paris Agreement; they considered how the agreement evolved from prior efforts, the structure of its commitments, and its implications for the future. This Dialogue presents a transcript of the discussion, which has been edited for style, clarity, and space considerations.
