The Climate Question

• Why don’t we use more geothermal energy?

  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 world's most sought-after metals: Lithium. Plus, our reporter in Indonesia tells Graihagh about local opposition to some geothermal power plants. The programme was first broadcast in 2024. Got a question you’d like answered?

• How does extreme heat affect pregnancy?

  Graihagh Jackson and the BBC’s former Global Health Correspondent Tulip Mazumdar investigate how extreme heat, fuelled by climate change, is affecting pregnant women in India. In the southern state of Tamil Nadu, Tulip hears the heart-breaking stories of some of the women affected and explores simple solutions that would make their work in scorching agricultural fields safer. The programme was first broadcast in 2024.

• Will the switch to green technology become unstoppable?

  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 making EVs mainstream.So, could positive tipping points hold the key to addressing the climate crisis? Hosts Graihagh Jackson and Jordan Dunbar speak to Professor Lenton about how positive tipping points happen and what we can learn from them. Got a question?

• Will there be a solar power boom in Africa?

  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. Countries like Liberia, DRC, Benin, Angola, and Ethiopia have tripled their imports. So, is this the start of a solar-powered revolution on the continent? Hosts Graihagh Jackson and Jordan Dunbar speak to Dr Rose Mutiso, Science Advisor at the Energy for Growth Hub and Founder of the African Tech Futures Lab. Got a question?

• Are wetlands our secret weapon in fighting climate change?

  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.This programme was first broadcast in 2024.Production team: Osman Iqbal, Octavia Woodward, Brenda Brown, Simon Watts Sound design by Tom Brignell.Send your questions to: [email protected]
