Climate Risk and Insurance - Raghavendra Rau

Watch the Q&A session here: https://youtu.be/Hwl0YRRaHgEWhy did coastal homeowners lose insurance while UK energy bills spiked after Russia’s invasion? Because risks started moving together. In this lecture, I show how climate extremes and geopolitics create synchronized shocks that overwhelm insurers and energy suppliers, pushing up premiums and bills. I discuss the basics of risk pooling, why it breaks under correlation, and what realistic fixes look like—from parametric policies and better building standards to smarter hedging and targeted support. This lecture was recorded by Raghavendra Rau on the 18th of February 2026 at Barnard's Inn Hall, LondonRaghu is the Mercers School Memorial Professor of BusinessHe is also the Sir Evelyn de Rothschild Professor of Finance at Cambridge Judge Business School.The transcript of the lecture is available from the Gresham College website: https://www.gresham.ac.uk/watch-now/climate-insuranceGresham College has offered free public lectures for over 400 years, thanks to the generosity of our supporters.

Peacebuilding through the visual Arts - Jolyon Mitchell

How can the visual arts be used to promote peace? Professor Mitchell investigates how the visual arts can not only incite violence, but also bear witness, reveal dangerous memories, transform violence, contribute to healing trauma and imagine more hopeful futures. Examples are taken from both current conflicts (Russia-Ukraine, Israel-Palestine) and past wars (Paul Nash and Otto Dix in the First World War, local artists in the Iran-Iraq War and the 1984 Rwandan genocide). Professor Mitchell analyses the ambivalent role of the visual arts in building peace.This lecture was recorded by professor Jolyon Mitchell on 11th February 2026 at Bernard’s Inn Hall, LondonProfessor Jolyon Mitchell is Principal of St John’s College, Durham and a Professor at Durham University who specialises in Religion, Violence and Peacebuilding, with reference to the arts and media.

Will You Be AI’s Pet? - Matt Jones

Watch the Q&A session here: https://youtu.be/fuk6LYeOCDQI have two pet dogs; they are happy, wagging their tails and reacting well when I come home from work. They are well fed; have good healthcare; get daily exercise; and have times of play; they do no work or chores. But their long-gone ancestors were wolves, howling at the moon, hunting, creating their packs, taking risks. In this lecture, we will consider a similar domestication of humans by AI, pondering benefits as well as being clear about the costs.This lecture was recorded by Professor Matt Jones on the 3rd Feb 2026 at Barnard’s Inn Hall, London.Matt Jones is a computer scientist at Swansea University - and a Fellow of the British Computer Society - who works alongside colleagues from many other disciplines and directly with everyday folk across the world to explore the future of digital technologies. Over the last 30-plus years, this human-centred approach has led to novel approaches for, amongst other things,  mobile phone-based information searching and browsing, pedestrian navigation, voice assistants and deformable displays.  Much of his work has been driven by intense and sustained engagements with “low resource” communities from informal settlements in India, South Africa, and Kenya. Through their generous and gracious participation, these extra-ordinary users with the fresh and diverse perspectives have stimulated insights into the future of digital technologies for everyone, globally. In all this work, Matt works as part of a long-standing collaborative team with Jen Pearson, Simon Robinson and Thomas Reitmaier (from Swansea) and colleagues in India (including Dani Raju) and South Africa (including Minah Radebe). His work has been supported by the UK’s science funders (EPSRC and UKRI). Currently, this funding includes a Fellowship to explore the future of interactive AI and leadership roles in responsible AI and inclusive digital technologies. This funding has led to a series of impactful publications, talks and influences on people, policies, and practices. Matt has collaborated with private, public and third sector organisations, including Microsoft, the NHS, Google, IIT-B, the BBC and IBM. He is a member of the Foreign and Commonwealth Development Office’s Research Advisory Group and Welsh Government’s AI reviews.The transcript and downloadable versions of the lecture are available from the Gresham College website: https://www.gresham.ac.uk/watch-now/ai-petGresham College has offered free public lectures for over 400 years, thanks to the generosity of our supporters.

An Ocean of Air - Helen Czerski

Watch the Q&A session here: https://youtu.be/_HJt1zjecCoThe major environmental challenge of our time is framed in terms of what happens in our atmosphere, and specifically what are called “greenhouse gases”. But what is an atmosphere, and how does it behave? Does the atmosphere vary across the world, and what enters and leaves it normally? This lecture will explore how humanity has taken some things from the air and put other things into it, what the effects have been, and what this means for our future.This lecture was recorded by Professor Helen Czerski on the 22nd January 2026 at Barnard’s Inn Hall, London.Dr Helen Czerski is a physicist and oceanographer with a passion for science, sport, books, creativity, hot chocolate and investigating the interesting things in life. She is an Associate Professor at the Department of Mechanical Engineering at University College London and her research focus is the physics of breaking waves and bubbles at the ocean surface. These bubbles change underwater sound and light, help transfer gases from ocean to atmosphere (helping the ocean breathe) and also eject ocean material into the air. She has spent months working on research ships in the Antarctic, the Pacific, the North Atlantic and the Arctic, and is an experienced field scientist. Helen has been a regular science presenter on the BBC for 15 years, covering the physics of the natural world in BBC2 landmark documentaries (including ‘Orbit’, ‘Operation iceberg’ and ‘Supersenses’), and the physics of everyday life in a range of BBC4 documentaries (including ‘From ice to fire: The incredible science of temperature’, ‘Sound waves: The symphony of physics’, and ‘Colour: The spectrum of science’, along  with many others). She currently co-hosts BBC Radio 4’s flagship climate and environment programme Rare Earth. Helen's first book Storm in a Teacup won the Italian Asimov Prize and the Louis J. Battan Author prize from the American Meteorological Society. Blue Machine won the Wainwright Prize for Conservation Writing. She was awarded the Institute of Physics Gold Medal in 2018 for her work on physics communication, and an Honorary Fellowship of the British Science Association in 2020. She has been a Trustee of Royal Museums Greenwich since 2018, and was one of the 2020 Royal Institution Christmas Lecturers, giving her Lecture on the topic of the ocean.
