Otavio Ranzani as Vice-Chair on the Global Climate & Health Summit

🌍 The Global Climate and Health Summit 2025 took place on 16–17 July at the QEII Centre in London and online, gathering in person 200 multidisciplinary leaders in science, health, policy, and advocacy from across the world. I had the honor of serving as one of the Vice-Chairs of this remarkable event, supported by the Wellcome Trust and organized by The Physiological Society.

Climate change is the greatest health threat of our time. From worsening air pollution to heatwaves, floods, and malnutrition, the effects are widespread and growing. This Summit aimed to catalyze collective action, bringing together scientists, policymakers, funders, and people with lived experiences of climate-related health impacts to co-create real-world, scalable solutions.

During the event, I also moderated the Innovation ThinkTank on Air Pollution, where innovators presented projects aimed at tackling global air pollution health challenges. This high-energy session connected researchers with potential collaborators and supporters to help scale their ideas globally.

🏛️ As a Steering Group member, I worked alongside brilliant colleagues, including Professor Mike Tipton (Chair), Dr Fortunate Machingura, and Dr Anh Vu. You can see the full Steering Group here:
