Albertine Conversations

A conversation with Laurence Tubiana and Alexis Abramson, moderated by M. Sanjayan

The Paris Climate Agreement was unanimously adopted by 194 countries in 2015 against considerable odds.  The Agreement set an ambitious goal of limiting the global average temperature increase to well below 2°C above pre-industrial levels and pursuing efforts to restrict the increase to 1.5°C. The United States, a major force in the successful ratification of Accord, has since pulled out of the agreement twice, most recently in January 2026.

Can international policymaking still play a significant role in addressing the climate crisis?  Laurence Tubiana, Dean of the Paris Climate School at Sciences Po and a primary architect of the Paris Agreement, joins Alexis Abramson, Dean of the Columbia Climate School, to explore how countries can continue to strengthen international cooperation in face of the climate crisis. As the two Climate Schools come together to launch a Dual Master’s in Climate, Tubiana and Abramson will be asking how multilateral platforms can still be relevant to generate action to combat climate change. Their conversation will be moderated by M. Sanjayan, CEO of the New York Climate Exchange.

This event is organized by Villa Albertine in partnership with the Columbia Maison Française, Alliance Program, and Columbia Climate School, and with the participation of the New York Climate Exchange.

A discussion organized by Villa Albertine, the Columbia Maison Française, the Alliance Program, and the Columbia Climate School.

The inaugural event brought together Corine Pelluchon, a French philosopher whose work examines the moral and political underpinnings of our relationship with the environment; Ana Porzecanski, Director of the Center for Biodiversity & Conservation at the American Museum of Natural History; Cyrille Barnerias, Director of International Relations at the French Office for Biodiversity; and Kristina Douglass, an archaeologist and professor at the Columbia Climate School. The conversation will be moderated by Sarah Sax, an award-winning investigative journalist and researcher specializing in environmental issues.

Together, they reflected on the idea of a “New Enlightenment” for the Anthropocene era. As we confront the decline of biodiversity, the discussion explored emerging forms of interdependence among human, animal, and plant life. How might the ways earlier societies and ecosystems co-adapted to climate pressures inform us today? Can we imagine a new social contract that would bring forth a more equitable coexistence between human and nonhuman worlds? How might an expanded sense of “the other” and a heightened awareness of contemporary vulnerabilities be translated into public policy? How can public engagement be designed to turn these concepts from ideals to actions?
