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?

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.

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.

Winter sport depends on one thing that is becoming less reliable each year: snow. As temperatures rise, glaciers are retreating, seasons are shifting, and lower-elevation resorts are struggling to guarantee consistent conditions.

Hosts Graihagh Jackson and Jordan Dunbar explore the ways climate change is reshaping winter sport, from elite competition to local economies. Former alpine ski racer and BBC Ski Sunday presenter Chemmy Alcott describes how competitors have to deal with shorter training seasons, cancelled races and increasing injury risks.

They also speak to Daniel Scott, a leading researcher on climate change and winter tourism at the University of Waterloo in Canada, about which cities may still be able to host the Winter Olympics and Paralympics by the 2050s. And Professor Scott tells The Climate Question how organisers are adapting through snowmaking, snow storage and changes to competition schedules.

Fear, anxiety, sadness, anger, dread and powerlessness are some of the many emotions associated with what’s called climate anxiety.

A global survey of 10,000 young people aged between 16–25 years, found that 60% were very worried about climate change, and nearly half said that their anxiety negatively effects their daily life.

Psychologists say these are rational responses to our changing climate, experienced in many different ways around the world.

Graihagh Jackson asks how people can manage these difficult emotions and whether climate anxiety itself can be motivational.

Graihagh chats to:

Svetlana Chigozie Onye who leads the Eco-anxiety in Africa Project, which looks at the mental health impact of climate change and solutions across Africa.

Dr Daniella Watson, Chartered Health Psychologist and a Research Associate at the The Climate Cares Centre, Imperial College London.

We know the planet is getting hotter because of human-induced climate change. But just how hot could it get?

In this show, Graihagh Jackson and Jordan Dunbar chat to Nasa scientist, Kate Marvel, about the world of climate modelling. Kate has spent decades trying to work out what will happen to the Earth as emissions of carbon dioxide increase.

Although the basic facts of climate change are settled, climate modellers are trying to understand how photosynthesis by plants will change in a warmer world. And they’re also puzzling over the crucial role played by clouds!

Recently, Kate has written Human Nature, a book about how climate change affects our emotions - from grief and anger to hope and love. She says the wide range of feelings prompted by global warming are compatible with getting the science right.

How farmers and scientists in eastern India are using ancient rice seeds to fight the growing impact of flooding, soil salinity and drought.

The BBC’s William Kremer tells Graihagh Jackson about his visit to the Sundarbans in West Bengal, where cyclones and rising sea levels have devastated crops. William meets the rice growers drawing on the skills of their forefathers to feed their families. Graihagh also gets a global overview from Dr Rafal Gutaker, rice expert at Kew Gardens, London. This programme was first broadcast in 2025.

Across the world, cars are getting taller, wider and heavier. Sports Utility Vehicles, or SUVs, now dominate global car sales, and the trend has continued into the electric age with many new EVs larger than ever.

In this episode of The Climate Question, Jordan Dunbar examines why bigger cars have become so popular with drivers and so profitable for manufacturers. From comfort and safety to status and aspiration, SUVs are reshaping roads across Europe, Asia and the Middle East.

Size matters. Heavier vehicles use more energy, require bigger batteries, and create challenges for cities, from congestion and parking to road damage and safety. Jordan speaks to Theo Leggett, the BBC’s International Business Correspondent, and Anjani Trivedi, Global Business Correspondent at The Economist, about car-spreading, emissions, electrification, and whether governments and consumers could reverse the trend.

People often ask whether there are any quick fixes to the climate crisis — easy wins that could cut emissions without waiting decades. This week, The Climate Question does something a little different.

Graihagh Jackson and Jordan Dunbar stage an imaginary cabinet meeting, with three “ministers” competing to deliver the biggest climate impact in just five years. Climate scientist and YouTuber Adam Levy pitches methane cuts in food and farming. Radhika Khosla, an urban climatologist and adviser to national governments, argues building smarter and reducing air conditioning are the fastest levers. And Jordan steps into the role of Transport Minister to make the case for buses, bikes and less traffic.

Together, they explore whether these quick fixes are enough — and why, if they’re so effective, they aren’t already happening.

Whales are among the largest animals to have ever lived – and scientists are discovering they also play a big role in the climate system. From the food they eat to where their waste and bodies end up, whales help move carbon from the atmosphere to the deep ocean, where it can be locked away for centuries.

This week, Graihagh Jackson and Jordan Dunbar explore what whales can tell us about climate change – and how warming seas may be affecting them in return. They speak to Victoria Gill, BBC Science Correspondent, about new research analysing Antarctic seabed samples to trace how whale populations influence long-term carbon storage.

They also hear from Helen Czerski, physicist, oceanographer and author of Blue Machine: How the Ocean Shapes Our World, about one of the most surprising scientific records of all: whale earwax – and how it reveals stress levels in the changing oceans.
