The Climate Question

Graihagh Jackson is joined by her regular panel to answer climate-related questions from listeners. BBC climate editor Justin Rowlatt, Prof Tamsin Edwards of King's College London, and Dr Akshat Rathi, senior climate reporter for Bloomberg News, discuss telling children about climate change, solar panels, nuclear fusion and more.

Plus, Graihagh finds out if playing music really helps plants to grow.

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 desi...

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 ef...

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 ...

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, G...

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...

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 po...

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 cha...

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 s...

The BBC’s Global Health Correspondent Tulip Mazumdar investigates how extreme heat fuelled by climate change is affecting pregnant women in India. New research shared with the BBC suggests that pregnant informal workers in Tamil Nadu who were exposed to high temperatures saw double the risk of stillbirth, premature birth, low birth weight and miscarriage.

Discussing her reporting from India with The Climate Question host and fellow...

You asked, we answered. This week our expert panel dive into your questions. Can climate change cause earthquakes and volcanic eruptions? How bad are avocados for the environment? Is climate change reversible?

Send your questions to: theclimatequestion@bbc.com Plus, a look at biofuels and vertical farming, China’s electric vehicle boom, and the apparent contradiction between more renewable energy and the continuing rise in pla...

As governments and industry find ways of reducing emissions to keep climate change under control, some people are taking responsibility for their own carbon footprints.

In this episode, Graihagh Jackson explores some different ways of living a green life – from setting up an eco-friendly commune in Denmark, to making small adjustments to our lifestyles in cities such as London. Graihagh also talks to one of the UN's top experts on ...

As climate change makes the world hotter, some cities have appointed "Chief Heat Officers" to try to improve their response to record-breaking temperatures. Graihagh Jackson speaks 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 the extreme heat gripping the city...

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 ...

At the big COP climate summit last December, more than 20 countries pledged to triple global nuclear capacity by 2050 to help cut carbon emissions. The signatories included familiar nuclear names such as the US, France and Japan...but also newcomers, like Ghana.

Although Ghana doesn’t currently have any nuclear power plants, president Nana Akufo-Addo says he wants to build one or two by 2030. So why is this African nation turning t...

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?

Graihagh Jackson travels to wetlands near her home in East Anglia while Qasa Alom reports from the Bay of Bengal. And The Climate Question catches up with an old friend of the show, Dr Musonda Mumba, Secretary-General of the Convention on Wetlands.

Global temperatures have already increased by around 1.3C above pre-industrial levels, but this warming is not spread evenly across the planet. The Arctic, despite being one of the coldest regions on Earth, has become a hotspot for global warming.

Local temperatures there are rising as much as four-times faster than in other parts of the world. This rapid warming is unsettling the delicate environmental balance, causing significant...
