Paris, 1 July 2025 -  A major project spearheaded by the President of Sciences Po, Luis Vassy, the Paris Climate School is the first European school in the humanities and social sciences dedicated to equipping future leaders with the tools to lead the transition, manage risks, and enhance the resilience of our societies. This new school becomes Sciences Po's eighth graduate school. Starting in September 2026, it will offer a two-year English-taught Master  in 'Ecological Transition, Risks and Governance', welcoming an initial cohort of around 100 students. The school will be led by Laurence Tubiana, whose exceptional experience at the crossroads of science, diplomacy, and public policy reflects the Paris Climate School's ambition: to train and educate a new generation of decision-makers ready to face the ecological emergency. Economist and diplomat, Laurence Tubiana has chaired the European Climate Foundation since 2017. She served as France's chief climate negotiator for COP21 and co-chaired the Citizens' Climate Convention in 2020. From January to June 2025, she co-chaired the Paris Climate School's preliminary mission with Sophie Dubuisson-Quellier, director of Research at CNRS and head of the Centre for the Sociology of Organisations (CSO) at Sciences Po. Sophie Dubuisson-Quellier will head the Scientific Committee, composed of permanent faculty members and teachers who will be involved in the school. 'In light of the scale and urgency of the ecological crisis, we have a responsibility to act. With the launch of the Paris Climate School—Europe's first school dedicated to climate—we are preparing a new generation of intellectually equipped leaders, ready to understand the profound transformations ahead and to shape systemic solutions. The Paris Climate School will train professionals across the public and private sectors to finance, plan, and manage the transition. I am delighted that Laurence Tubiana has agreed to become Dean of the Paris Climate School. Her unique experience at the intersection of economics, climate diplomacy and public policy embodies the ambition of this school. It is a major milestone for Sciences Po.'  Luis Vassy, President of Sciences Po 'I am immensely proud and excited to be named Dean of the Paris Climate School. Its creation comes at a decisive moment for our planet and our societies. Responding to the ecological emergency requires a new generation of thinkers and actors. Sciences Po has the potential to become a global leader on climate, by combining academic excellence, interdisciplinarity, and civic engagement.'

Paris, 18 June 2025 – The third issue of Comprendre son temps, the journal published by Sciences Po, offers an in-depth analysis of contemporary conflicts amidst heightened geopolitical tensions. Political scientist Hugo Micheron, who specialises in the Middle East and jihadism, coordinated the contributions of ten researchers who aimed to explore the new forms of conflict that have recently emerged: the militarisation of digital space, the weaponisation of information, the reconfiguration of alliances and power dynamics, the hybridisation of threats, and the return of high-intensity warfare — from Ukraine to Gaza. These contributions examine the systemic transformations redefining the attributes of power and critically assess Europe’s evolving role in the global order. Contributors to this issue include Thierry Balzacq, Professor and researcher at the Centre for International Studies (CERI); Christophe Jaffrelot, CNRS Research Director at CERI; and Frédéric Ramel, Professor and researcher at CERI. Regular contributors to Sciences Po have also participated, such as writer and lecturer Giuliano Da Empoli; Asma Mhalla, political scientist and lecturer; and author Karine Tuil. Hugo Micheron, scientific director of the issue : “The current period is marked by profound geopolitical transformations that challenge Europe’s place and role on the world stage, as well as its ability to assert itself as a leading geopolitical actor. It is essential for a group of influential EU countries to align their diplomatic orientations in order to rethink conflict in all its strategic dimensions. This is the collective analysis put forward by Sciences Po researchers in this issue." Luis Vassy, Director of Sciences Po :  "In an era where conflict is no longer an exception but a structural reality, it is vital to place this notion at the heart of both our scientific inquiry and educational mission." About Comprendre son temps Comprendre son temps is Sciences Po’s journal in the humanities and social sciences, offering insights into the major ruptures shaping today’s world and supporting both public and private decision-making. Published biannually, it seeks to make the institution’s high-quality academic research accessible to the widest possible audience by addressing a major social and political issue.
