Should we mine the deep ocean?
In the global race for critical minerals - could the seabed provide solutions? Or should we leave these metal-rich environments undisturbed? Governments and mining companies around the world are on the hunt for the critical minerals we need for the green tech transition. And there’s growing interest in an unlikely source – potato-shaped nodules that are found kilometres below the surface of our oceans. These polymetallic nodules contain high levels of elements like cobalt, nickel, manganese and copper. Supporters of deep-sea mining say that harvesting them might be less damaging to the environment than mining on land. But many scientists support a moratorium; they say industrial activity on the seabed could damage the biodiversity of a fragile part of our planet.The BBC’s Climate and Science Reporter Georgina Rannard has been following the deep-sea mining debate for five years. She chats to Hosts Graihagh Jackson and Jordan Dunbar.Got a question or comment?

The electric car boom in South East Asia
Electric vehicle sales are soaring in Thailand and Vietnam. What’s behind the boom? And will it help the climate? Thais and Vietnamese are switching to electric cars in huge numbers – attracted by government subsidies and a more exciting range of EVs. Jobs in the car industry are also up in both countries as a new generation of manufacturers compete for domination of the emerging electric market. But can the pace of growth last? Will the boom in electric cars reduce the chronic air pollution in cities like Bangkok? And will it help Thailand and Vietnam reduce their carbon emissions? In this edition of The Climate Question, Host Jordan Dunbar chats to Ember’s Asian Energy Analyst, Lam Pham and Bloomberg’s Thailand Reporter, Patpicha Tanakasempipat. Got a question or comment?

Is this climate change or just crazy weather?
It’s one of the most commonly debated questions in the climate world: Is this weather we’re experiencing natural, or is it linked to man-made climate change? In this episode of The Climate Question, Hosts Graihagh Jackson and Jordan Dunbar are joined by BBC Lead Weather Presenter, Matt Taylor. Matt’s forecasts are seen not just in the UK but around the world. Matt chats to Graihagh and Jordan about the crucial difference between weather and climate, and the challenge of communicating this on air. They discuss why heavy snowfall will still be possible in a warmer world, as well as the likely increase in droughts, heatwaves and extreme weather. Matt also talks about whether climate change will make his forecasts more or less accurate. And he tells Graihagh and Jordan about an encounter with BBC wildlife legend, David Attenborough!Got a climate question or comment?

Chernobyl at 40: Is nuclear power back in fashion?
In 1986, the Chernobyl nuclear accident devastated the Soviet Union and shocked the world. But, 40 years on, are we now seeing a nuclear renaissance? And what does that mean for the climate? Climate Question host Jordan Dunbar has just visited the most contaminated place in the world for a BBC World Service documentary. He tells co-host Graihagh Jackson about the ghostly atmosphere in the former Chernobyl control room and the huge dome that now covers the remains of the nuclear reactor that exploded. Jordan and Graihagh also discuss how the disaster set back the nuclear power industry for decades. Now, however, nuclear is firmly back on the international agenda because of rising power demand and concerns about energy security. With around 40 countries now aiming to build more nuclear power stations, what will this mean for the climate and the world’s goal of keeping global warming under control?

Can technology help us fight flooding in cities?
With more and more people moving to cities, informal settlements are expected to grow. When floods hit these unplanned places, it can be disastrous, as we often don’t know much about them. Crucial questions often remain difficult to answer, like how many people live there, what are the buildings made of, and could they withstand a flood? In the township of Alexandra in Johannesburg, the BBC’s Nomsa Maseko visits a project using drones and artificial intelligence to help authorities prevent the worst impacts of flooding. And in Porto Alegre in the south of Brazil, we hear how an innovative digital map helped the emergency response – and will soon be available to all for free across the world.This programme was first broadcast in 2024.

Earthquakes and climate change
Earthquakes are caused by a sudden release of stress along faults in the earth's crust, not by climate change, but some new studies suggest that melting glaciers and permafrost may influence when, where and how often seismic activity occurs. In this episode, hosts Graihagh Jackson and Jordan Dunbar chat to seismologist Dr. Verena Simon from the Swiss Seismology Service and Associate Professor of Geosciences at Colorado State University, Sean Gallen.

Why are some cities banning fossil fuel ads?
How much does advertising influence what we buy and how we think?A growing number of cities are restricting adverts for fossil fuel products, from flights and petrol cars to gas heating. From May, Amsterdam is set to become the first capital city to do so. In 2024, the UN Secretary-General António Guterres called on countries to introduce similar bans worldwide.In this episode of The Climate Question, Jordan Dunbar asks whether banning fossil fuel adverts is a good idea and whether it makes any difference when it comes to fighting climate change.He speaks to Marco Silva from BBC Verify about the role advertising plays in shaping public attitudes, and Anna Holligan, the BBC's correspondent in The Hague, explains how the restrictions in The Netherlands actually work.Guests: Anna Holligan – BBC correspondent in The Hague Marco Silva – Senior journalist, BBC VerifyGot a question or comment? email us at theclimatequestion@bbc.comProduction team: Grace Braddock, Diane Richardson, Nik Sindle, Melanie Stewart-Smith Sound Engineer: Tom Brignell and James Piper Production Coordinator: Brenda Brown Editor: Simon WattsPicture: Getty Images
What's it like being a Chief Heat Officer?
As climate change makes the world hotter, some cities have appointed so-called Chief Heat Officers to try to improve their response to record-breaking temperatures. In 2024, Graihagh Jackson spoke to two women who have done the job in Freetown, Sierra Leone, and Monterrey, Mexico. What does their role involve? What solutions are out there? And do they get enough funding?Plus, Umaru Fofana reports from Freetown on what happens when extreme heat grips the city. Umaru talks to locals forced to sleep outside because of the temperature, despite risks to their health and safety. And he also investigates a new piece of building design that might help people living in informal settlements.Got a question or comment? email us at theclimatequestion@bbc.comPicture Credit: Anadolu, Getty Images.Presenter: Graihagh Jackson Reporter in Sierra Leone: Umaru Fofana Producer: Osman Iqbal Researcher: Octavia Woodward Sound Engineers: James Beard and Tom Brignell Editor: Simon Watts
Can better buses fix city pollution?
Transport is one of the fastest-growing sources of greenhouse gas emissions, and in cities around the world it is also one of the biggest daily frustrations. Congestion, pollution and long journeys to work affect millions of people every day.In this episode of The Climate Question, Jordan Dunbar explores how cities can move large numbers of people more quickly, cheaply and with fewer emissions. With most urban journeys still dominated by private cars, the challenge is how to shift people towards more efficient forms of transport.He speaks to Dario Hidalgo, a transport expert based in Bogotá, where a system known as Bus Rapid Transit has helped transform how millions of people travel. By giving buses dedicated lanes, larger vehicles and faster boarding systems, cities can move more people using fewer vehicles, cutting both congestion and emissions. Variations of the model are now being used in cities around the world.Jordan also hears from Sarah Kaufman, Director of the NYU Rudin Center for Transportation in New York, about why similar systems can be harder to implement in dense cities, and how measures like congestion charging are helping to reduce traffic and fund improvements to public transport.While electric cars are often seen as part of the solution, both experts say reducing the number of cars on the road altogether is key. From buses to bikes, they explore how cities might redesign transport systems to be cleaner, faster and more efficient.Guests: Dario Hidalgo – Professor of Transport and Logistics, Pontificia Universidad Javeriana, Bogotá Sarah Kaufman – Director, NYU Rudin Center for Transportation, New YorkGot a question or comment? email us at theclimatequestion@bbc.comProduction team: Grace Braddock, Diane Richardson, Nik Sindle, Melanie Stewart-Smith Sound Engineer: Tom Brignell and Mike Regaard Production Coordinator: Brenda Brown Editor: Simon WattsImage: Guillermo Legaria/AFP via Getty Images

Is cutting methane the quick way to cool the planet?
Methane is much more powerful than carbon dioxide and emissions are still rising. So what can we do to tackle the human-made sources of this greenhouse gas? And could this buy us time to get to grips with climate change?It's a topic which many Climate Question listeners have been contacting us about. So in this episode Hosts Graihagh Jackson and Jordan Dunbar put some of your questions and comments to Mark Maslin, Professor of Earth System Sciences at University College London.What makes methane so powerful? Is meat production to blame? And what about leaks and gas-flaring in the fossil fuel industry?Got a question or comment, email us at theclimatequestion@bbc.com Production team: Simon Watts, Diane Richardson, Grace Braddock Sound Engineers: Tom Brignell and James Piper Production Coordinator: Brenda Brown Editor: Simon Watts
China's green energy revolution
China is installing solar panels and wind turbines so fast that its greenhouse gases emissions may now have peaked. If this trend is confirmed, it would be a major milestone in the fight against climate change because China is the world's largest polluter.The BBC’s Beijing Correspondent Laura Bicker has travelled across China to see the country’s clean energy revolution first hand. She’s visited solar farms in the deserts of Inner Mongolia and in the tea plantations of Yunnan. Laura even discovered a huge lake with panels floating on the surface! But she also saw how China’s addiction to coal is continuing – with new power plants still being built and many poorer Chinese needing to burn coal to get through the winter. In this edition of The Climate Question, Laura chats about her reporting with hosts Graihagh Jackson and Jordan Dunbar. They discuss whether the world’s biggest polluter is moving fast enough to meet its green energy targets, and what that means for China and the rest of the world. Got a question you’d like answered?

What can we do to reduce black carbon?
First broadcast in 2024. Graihagh Jackson finds out about the little know pollutant making us sick and driving the climate crisis. It commonly comes from burning coal, diesel or wood and has a habit of getting stuck in people’s lungs as well as causing glaciers to melt. In Nepal, home to some of the world’s most beautiful glaciers, we meet journalist Tulsi Rauniyar, who tells us all about the impact black carbon is having on women and children. She meets Tenzing Chogyal Sherpa, a glacier expert who maps the ice losses in the Himalayas. Zerin Osho from the Institute for Governance & Sustainable Development helps us understand why black carbon is so important - but often forgotten - in the fight against climate change, and how we can change that.
