The Climate Question

Storms, cyclones and flooding in South East Asia have killed close to 2000 people, devastating communities across Indonesia, Malaysia, Sri Lanka and Thailand. Scientists warn climate change is reshaping weather patterns, increasing the risk of heavier rainfall and more destructive floods in the future.

With many densely populated cities sinking and built on flood-prone land, the region is particularly vulnerable. But experts say there are bold ideas and solutions that could help reduce the risks and save lives.

In this special collaboration between The Climate Question and the new BBC World Service podcast Asia Specific, Graihagh...

What do you think of when you think about our oceans? Maybe you see a picture of our planet with a big patch of blue? Maybe you think about storms or dramatic ocean voyages? Maybe fish or coral reefs?

In this edition of The Climate Question, Hosts Graihagh Jackson and Jordan Dunbar explore how our oceans are even more important than you might imagine. They help put the brakes on climate change and regulate our weather - even in faraway deserts. They provide food, and even influence the rise of great civilisations, like Ancient Egypt.

Across the world vehicle manufacturers are racing to make zero emission cars in the move away from fossil-fuel powered vehicles. It’s a huge market which could reach 9 trillion dollars worldwide by 2030. One small country which is grabbing this opportunity is Hungary. Located in the heart of Europe but with a population of under 10 million, it’s becoming one of the top battery producers globally for electric cars.

This transition is bringing billions of euros of investment into the Hungarian economy and creating tens of thousands of jobs. One city in particular – Debrecen – the country’s second biggest, i...

How can the world speed up its efforts to fight climate change?

It’s been a dramatic fortnight at the COP climate summit in the Amazonian city of Belem, with torrential rains and floods, protests and even a fire. A deal has finally been done but it’s divisive and has left many wondering whether we'll really avoid the worst effects of a warming world.

Join Jordan Dunbar and Graihagh Jackson as they take a deep dive into the results of the negotiations and find out what they mean.

The American lawyer, oil lobbyist and master strategist Don Pearlman is said to have chain-smoked his way through almost every UN climate gathering from the early 1990s until his death in 2005.

Some of those who saw Pearlman operate in Kyoto, where the first legally binding international agreement on climate change was agreed in 1997, say he created the playbook for stalling climate talks. The Kyoto protocol was never ratified by the United States, and Pearlman is now the subject of a major play, Kyoto, which has just transferred from London to the Lincoln Center in New York.

Carbon dioxide is a molecule so important it has shaped life on Earth for billions of years. Without it, there would be no plants, no oceans, no people. But now, after centuries of burning coal, oil and gas, it's in the atmosphere at levels that alarm scientists.

In this episode of The Climate Question, Graihagh Jackson speaks to Peter Brannen, science journalist and author of The Story of CO2 is the Story of Everything, and Esme Stallard, BBC climate and science reporter.

They explore what makes this tiny molecule so powerful, how it has driven...

Every year, tens of thousands of people — from world leaders to activists to celebrities— gather for one of the world’s most ambitious meetings: the UN’s annual climate summit, COP.

But what does it actually take to make it happen? How do you feed, transport and house 80,000 people, while trying to keep global negotiations on track?

The Climate Question hosts Graihagh Jackson and Jordan Dunbar talk to Helen Wright, who helped deliver COP26 in Glasgow and COP28 in Dubai, to find out what goes on behind the scenes.

The Amazon is probably the most famous rainforest on Earth. It’s home to Indigenous communities, one of the world's biggest rivers and a diversity of plant and animal life found nowhere else. But it’s also a region rich in sought-after resources — gold, iron ore, bauxite, coffee and rubber — and vast areas of forest have been cleared for cattle and soy production. Scientists warn that deforestation and climate change are drying the region, fuelling fires, and risking a dangerous tipping point when the rainforest can no longer sustain itself and begins to release more carbon than it absorbs. This wee...

Mumbai is India’s economic engine, but every rainy season this megacity comes to a virtual standstill as torrential rains flood streets, homes and transport networks. In 2005, Mumbai faced one of its worst floods on record – and experts warn that climate change could make future rainfall even more intense.

This week, Graihagh Jackson and Jordan Dunbar explore what’s happening with Mumbai and the mighty monsoon – and how a city of more than 20 million people can adapt to a wetter, more unpredictable future.

They hear from BBC Marathi correspondent Janhavee Moole and Zerin Osho, Director of the I...

Today, more than half the world’s population live in cities – and as our numbers swell, so will our cities, especially those around the Pacific Rim, where it’s predicted our largest megacities of 10 million plus will be situated. And herein lies an opportunity: 60% of the buildings needed for 2050 are not yet built.

Could we shape our cities into places that are good for the climate and also good for our mental health? Can we design buildings and infrastructure that make green decisions easier and also help us deal with stress or depression?

Geothermal energy is renewable, reliable and powerful. So, why is most of it untapped? That’s what our listener, Anna in the UK, wants to know. Full disclosure, she’s a geologist and is thoroughly perplexed by the lack of uptake. Geothermal is renewable, reliable and abundant and yet, less than 1% of the world’s energy is generated from it. Host Graihagh Jackson hears about a team in Iceland who hope to "super-charge" geothermal power by drilling directly into volcanic magma. And she travels to Germany to visit Vulcan Energy, a company which is combining geothermal with extracting one of the...

When people talk about tipping points in the climate, it’s usually bad news – the irreversible melting of ice sheets or the collapse of rainforests. But could there be positive tipping points too, moments where climate solutions break through and spread rapidly?

Tim Lenton, Professor of Climate Change at the University of Exeter and author of Positive Tipping Points: How to Fix the Climate Crisis, says it’s already happening – from the dramatic rise of renewable energy to the surge in electric vehicles. He explains how in Norway, the 80s pop band A-Ha played a crucial role in makin...

Africa gets a world beating amount of sunshine — but has just 1% of the world’s solar panels.

Over half the continent still lives without electricity, stalling progress and holding back people’s lives. But change may be coming — thanks to a surge in solar imports from China.

New data from energy think tank EMBER shows a 60% jump in solar panel shipments to Africa in the past year. If installed, they could generate 15 GW — nearly doubling Africa’s current solar capacity.

It’s not just the biggest energy users like South Africa, Nigeria, and Algeria. Count...

The world's wetlands store carbon and can help us tackle some of the impacts of climate change. Are we overlooking their importance? And what can we do to protect them more?

President Trump has made sweeping changes to America's policies on climate since being sworn in 100 days ago. He has announced plans to "unleash" American energy, including revitalising the coal industry and boosting oil and gas. The president has also cut funding for clean energy projects and renewables, while slashing jobs in government-funded climate research. Experts also say Washington's trade tariffs are having a big impact on the global market for new technologies such as solar panels and electric vehicles.

So what does all this mean for the green transition in America and beyond? Graihagh Jackson talks to...

The southern US state of Georgia has received billions of dollars in investment in clean technology, creating tens of thousands of jobs at solar power factories and electric vehicle factories. It is also on the front-line of extreme weather - facing the threat of hurricanes, heatwaves and drought. So will voters in this swing state be considering climate change when they cast their ballots for the US presidential election in November? And how are politicians in Georgia talking about the issue. Jordan Dunbar takes a road trip across the state to find out.

Geothermal energy is renewable, reliable and powerful. So, why is most of it untapped?

That’s what our listener, Anna in the UK, wants to know. Full disclosure, she’s a geologist and is thoroughly perplexed by the lack of uptake. Geothermal is renewable, reliable and abundant and yet, less than 1% of the world’s energy is generated from it.

Host Graihagh Jackson hears about a team in Iceland who hope to "super-charge" geothermal power by drilling directly into volcanic magma. And she travels to Germany to visit Vulcan Energy, a company which is combining geothe...

Engineers across the globe, from China to East Africa and the US, are turning to a new, nature-based solutions to fight floods, which are becoming more likely in many places because of climate change. They’re taking a pickaxe to asphalt and concrete and instead are restoring wetlands, parks and riverbanks, turning our metropolises into so-called ‘sponge cities’. Plants, trees and lakes act just like a sponge, mopping up rainwater instead of letting it pool and eventually flood our homes.

Professor Priti Parikh tells Jordan Dunbar how these spongey solutions have many benefits beyond flooding, encouraging biodiversity, helpin...

Climate change has been tightening its grip on the people of Afghanistan, with flood after flood and drought after drought. It’s considered one of the most vulnerable countries in the world, not just because it’s warming twice as fast as the global average, but because its people’s ability to fight back has been severely hampered by decades of conflict and war. To add insult to injury, Afghanistan has contributed very little to the industrial emissions that fuel the global climate crisis.

Since the Taliban takeover in 2021, financial aid to help locals adapt has drastically droppe...

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 shed some light on the situation, helping authorities prevent the worst impacts of flooding. And in Porto Alegre in the sout...

This little-known pollutant is 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...

The Paris Olympics are less than a month away. The last games in Tokyo were one of the hottest on record, with more than a hundred athletes suffering heat-related illnesses. And France, the host of this year’s Olympics, is no stranger to heatwaves – the country has seen 23 since 2010.

So how are top athletes training their bodies to not only perform at their best in high temperatures, but also to protect their health? Presenter Qasa Alom heads inside a sweltering, state of the art heat chamber at Leeds Beckett University to find out how one of the fast...

As a new play depicts the landmark global climate change agreement, the Kyoto protocol, Jordan Dunbar has a front row seat. He heads to the historic English town of Stratford-Upon-Avon to watch the opening night of the play, Kyoto, at the Royal Shakespeare Theatre. He hears why the writers, Joe Murphy and Joe Robertson decided to dramatize the seemingly slow and tedious action of a global climate change conference. And the duo explain their goal to highlight Kyoto as a ‘parable of agreement’ in a world full of disagreement.

The programme also hears from two veterans of many...

Someone dies every other day protecting the environment, according to data gathered by the campaign group, Global Witness. Even higher numbers of people are attacked or threatened.

To understand why this is happening, the BBC’s East and Central Europe Correspondent, Nick Thorpe travels to the foothills of the Carpathians in Romania, to show us how important the forests there are in fighting climate change, why they’re subject to high levels of illegal logging and consequently, clashes with environmentalists. One activist, Gabriel Păun of Agent Green, describes the numerous and brutal attacks he’s experiences whilst...

Billions of dollars have been pumped into the promise of a climate-friendly way of producing meat, but is growing a steak in a lab any better for the planet than rearing a cow on a farm? Supporters of the idea say it will dramatically reduce the impact of livestock, which is responsible for about 15% of the world’s planet-warming gases, as well as returning huge amounts of land to nature. But studies suggest cultivating meat in a lab might actually be worse for the planet, at least in the long-run – we put both claims to the test. Graihagh Jackson pres...

China is scouring the globe for the raw materials of the future. How will we be affected? Graihagh Jackson investigates.

Today, more than half the world’s population live in cities – and as our numbers swell, so will our cities, especially those around the Pacific Rim, where it’s predicted our largest megacities of 10 million plus will be situated. And herein lies an opportunity: 60% of the buildings needed for 2050 are not yet built.

Could we shape our cities into places that are good for the climate and also good for our mental health? Can we design buildings and infrastructure that make green decisions easier and also help us deal with stress or depression?

Jordan Dunbar hears...

Experts say we need to be 40 per cent more energy efficient to meet our climate goals. Is that doable? And might it save us money too?

It's a solution that's been called the main route to net zero: energy efficiency - or using less energy to get the same or better results. But there’s an issue – it's got an image problem as many people think it’s boring. And it is hard to get excited about the idea of better lightbulbs!

But energy efficiency could save us money on our bills too - especially in a w...

In this episode, Graihagh Jackson explores the new field of climate attribution science with leading climatologist Dr Friederike Otto. Dr Otto's team of experts can now rapidly assess to what extent extreme weather events such as heatwaves, droughts or floods have - or have not - been caused by man-made climate change.

Graihagh finds out how this information is becoming crucial for disaster planning and response. She is also joined by BBC World Service disinformation reporter Jacqui Wakefield to discuss how Dr Otto's data can help fight a growing tendency by politicians and journalists to overstate the...

In this extra episode, Graihagh Jackson hears from our friends on BBC podcast The Global Story about a case that could change the history of climate activism.

For nearly a decade, a group of elderly women argued that Switzerland’s weak climate policies violated their human rights. Their victory – the first of its kind in the European Court of Human Rights – sets a precedent 46 countries must now follow. The BBC's climate reporter, Georgina Rannard, has been covering the case for years. She shares the women’s personal stories with presenter James Reynolds, while climate lawyer Sophie Marjanac explains...

Corals protect humans and sustain 25% of all marine life. But reefs are under threat from climate change, and mass bleaching events mean that some scientists estimate they could disappear by 2100.

In this episode, Graihagh Jackson is joined by BBC CrowdScience presenter, Caroline Steel. We go to Puerto Rico to see how self-duplicating, carnivorous coral could be the solution. We also speak to the scientist who helped discover what was causing coral bleaching in the first place - back when climate change was commonly denied.

Guests: Dr Ove Hoegh-Guldberg, Professor of Marine Studies at the University...

Ammonia has revolutionised the way we produce our food, helping us to grow much, much more... But it’s also helping to grow global greenhouse gas emissions too.

Synthetic fertilisers are actually responsible for around 5% of the planet-warming gases going into the air - that’s more than deforestation.

In this episode, Graihagh Jackson examines this challenge that modern agriculture poses to the climate, and finds out whether it’s possible to cut emissions from fertiliser use without cutting food production at the same time. She’ll also be joined by local reporters in Kenya to hear...

Delhi’s roads are being taken over by electric mopeds, scooters and rickshaws. More than fifty per cent of two- and three-wheelers are already electric, and the market is expected to continue growing. It’s good news for the fight against climate change. Why has the transition to green vehicles been so swift in India and what can the rest of the world learn from it?

Graihagh Jackson speaks to reporter Sushmita Pathak, who’s been chatting to those who’ve made the switch to electric as well as those who haven’t. Akshima Ghate from the RMI Founda...

Every year, the great migration sees hundreds of thousands of wildebeest, gazelles, zebras and antelopes migrate from the Serengeti plains in Tanzania to the Maasai Mara in Kenya, in search of water and juicy grass. But rising temperatures and unpredictable weather are changing this epic animal journey dramatically. It’s the same for great white sharks, which are being spotted in areas where they’d never normally live.

Tanzanian safari guide Neema Amos takes us into the Serengeti to explain why the wildebeest migration is so important. And shark expert Trisha Atwood reveals how these changes affect not...

The BBC’s Global Health Correspondent Tulip Mazumdar investigates how extreme heat fuelled by climate change is affecting pregnant women in India.

It may sound like the stuff of science fiction, but the idea of assembling giant solar farms in space and then beaming the renewable energy back down to Earth is gaining real life traction. Some advocates have claimed it could supply all the world’s energy needs by 2050.

But how would these solar farms be assembled, how much fuel and money would it take to blast them into space in the first place, and how would we safely beam their energy back to Earth?

In 2023, Sophie Eastaugh and Luke Jones spoke to Sanjay Vijendran, in ch...

Graihagh chats to the BBC World Service's Global Story podcast about a plan for a super-category for storms. Is climate change making them so powerful that we need a new grade?
