The Climate Question

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 u...

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 fr...

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 r...

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 an...

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 ...

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 the...

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 far...

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...

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 ...

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 th...

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 St...

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...

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 ...

BBC Climate Editor Justin Rowlatt travels to Somalia to investigate the links between global warming and the decades-long conflict there. He hears how Somalis are responding by launching businesses and their own renewables industry. This programme was first broadcast in 2024.

Presenter: Justin Rowlatt Producer in Somalia: Stuart Phillips Producers in London: Miho Tanaka, Sara Hegarty Sound Mix: Tom Brignell and David Crackles Editor...

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 mo...

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...

What can ice cores tell us about the atmosphere millions of years ago?

These cylinders of ice, drilled from glaciers and ice sheets around the world, preserve precious clues about our changing climate and records such as rainfall, temperature and greenhouse gases, even volcanic eruptions. But what can the past tell us about the future?

Host Graihagh Jackson hears from two ice core experts about their icy adventures in Antarctic...

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...
