As the conflict in the Middle East rattles energy markets, this episode explores the connections between climate change, energy, and geopolitics. It addresses questions such as:

• What does the war in Iran reveal about the links between fossil fuels, vulnerability, and power? What lessons can be drawn?
• What does the energy transition mean for global geopolitics, and how should governments manage the 'messiness' of the process?
• How are the impacts of climate change reshaping our world, and what can be done to navigate the challenges that arise?

To unpack these dynamics, Anna and Bhargabi are joined by Arthur Snell (a former diplomat and author of 'Elemental: The New Geography of Climate Change and How We Survive It'), Michael Bradshaw (Professor of Global Energy at Warwick Business School, Associate Fellow at Chatham House, and author of 'The Geopolitics of Energy System Transformation: Managing the Messy Mix'), and Dr Beatrice Mosello (Senior Research Fellow at Chatham House).

China is the world's largest emitter and dominates global production of green technology. A few days ago, the National People's Congress approved the country's 15th Five-Year Plan, China's main economic and policy blueprint for the period 2026–2030. What does the new plan say about China's climate and clean tech ambitions? And what does it reveal about China's broader geopolitical and foreign policy goals?

To discuss this, Anna is joined by James Kynge (Senior Research Fellow for China in the World at Chatham House's Asia-Pacific Programme) and Lauri Myllyvirta (Lead Analyst at and Co-founder of the Centre for Research on Energy and Clean Air, CREA).

What are the most important changes the Paris Agreement has brought about? How should the COP process evolve? And why does geoengineering need to be approached with caution?

The fourth part of the Future of Climate Diplomacy mini-series features a fascinating conversation between Chatham House's Chris Aylett (standing in for Anna and Bhargabi) and Laurence Tubiana, CEO of the European Climate Foundation and previously France's Climate Change Ambassador and Special Representative for COP21.

The race to secure critical raw materials is turning attention towards an unlikely place: the ocean floor. In this episode, Anna speaks with Dr Isaac Kardon (Senior Fellow at the Carnegie Endowment for International Peace) and Meredith Schwartz (Associate Fellow at the Centre for Strategic and International Studies) about the geopolitics of deep-sea mining.

The EU has introduced a Carbon Border Adjustment Mechanism (CBAM) to prevent carbon leakage – when companies move production to countries with weaker climate rules, or when EU products are replaced by more carbon-intensive imports. But the measure has sparked controversy and concern, especially among countries in the Global South, as seen during COP30 in Belém.

This episode of the Climate Briefing explores the implications of the EU's CBAM for countries in the Global South: What are their main concerns, and what could be done to mitigate negative impacts?

To discuss these questions and more, Anna is joined by Aparna Sharma (Programme Lead at the Council on Energy, Environment and Water – CEEW), Shimukunku Manchishi (Senior Policy Officer at the African Futures Policy Hub), and Ieva Baršauskaitė (Lead on Trade and Green Transition at the International Institute for Sustainable Development – IISD).

Exactly one year has passed since President Trump returned to the White House. How has the first year of Trump 2.0 impacted global efforts to address climate change, and what might happen going forward?

To discuss this, Anna and Bhargabi are joined by Gina McCarthy (former US National Climate Advisor, former EPA Administrator and Chair of the America Is All In Coalition).

In the final episode of the year, Anna speaks to Professor Tim Lenton (Chair in Climate Change and Earth System Science at the University of Exeter) about climate tipping points – the thresholds where a tiny change could lead to large and often irreversible transformations in the Earth system, with potentially disastrous consequences. Examples of such 'negative' tipping points include the dieback of the Amazon rainforest, the melting of the Greenland icesheet, and the collapse of the Atlantic Meridional Overturning Circulation (AMOC). But not all tipping points are bad. In the interview, Anna and Tim also discuss how the triggering of 'positive tipping points' within human societies could lead to rapid decarbonization.

COP30 in Belém is over. What happened at the conference? What were the main outcomes? And what needs to happen next?

To find out, Anna speaks to Jennifer Morgan (Senior Fellow at the Fletcher School of Law and Diplomacy at Tufts University; Fellow at the Hertie School of Governance; and former State Secretary and Special Envoy for International Climate Action at the German Federal Foreign Office) and David Waskow (Director for the International Climate Initiative at the World Resources Institute).
