The Climate Question

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...

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. Ema...

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 ...

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 do...

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.

Twenty years ago, Hurricane Katrina devastated America’s Gulf coast and overwhelmed the city of New Orleans. The destruction and the response to the storm became infamous and are debated to this day.

Climate scientists warn that the warming world is likely to make typhoons, cyclones and hurricanes more intense and so even more dangerous.

Graihagh Jackson and Jordan Dunbar ask what the world has learned since the disaster in New Orl...

This week Host Graihagh Jackson grabs a chat with the BBC’s correspondents in two countries that will shape our future climate.

Brazil is about to host the giant COP climate conference in the Amazon, but the pace of reducing deforestation has just slowed and there are concerns about potentially weaker environmental standards. Ione Wells in Sao Paulo also talks Graihagh through proposals for oil exploration in the mouth of the rainf...

Climate change is melting thousands of glaciers in the Himalayas and having a devastating impact on the people who live there. In 2024, the BBC's Caroline Davies visited the Pakistani side of the world's highest mountain range: she told Graihagh Jackson how villagers are coping, and how they are determined to stay put despite the risks of floods and the disruption to their traditional way of life.

Bill Gates, the tech billionaire turned philanthropist, has been combating poverty, disease, and inequity around the world for decades. However, in recent years he has shifted focus and resources towards the climate crisis.

Gates believes fighting climate change and fighting poverty are two sides of the same coin. Food, health and economic crises will last longer and become more severe as climate threats escalate, disproportionately...

From coral reefs and mangroves to raising the land itself, how small island nations are using natural and innovative techniques to adapt to rising sea levels and extreme weather events linked to climate change.

Jordan Dunbar chats to Tina Stege, climate envoy for the Republic of the Marshall Islands, and Dr. Rosanne Martyr, senior scientist on coastal vulnerability and adaptation, Climate Analytics.

Plus, Anna Holligan, the BBC's ...

Rare earths have been described as the oil of the 21st century, incredibly valuable both economically and in the fight against climate change. There's a battle underway around the world to mine and control these minerals - a battle that is currently being won by China.

As demand rises, the problems with rare earths are also becoming clearer because getting them out of the ground requires strip mining and the use of poisonous chemic...

Could changing weather patterns due to climate change make a difference to where and when we travel, or to the cost of our holidays?

It was the hottest June on record for Western Europe, according to the EU’s climate service, Copernicus. And the Intergovernmental Panel on Climate Change says that heatwaves in Europe will become more frequent, more intense and longer-lasting.

Extreme heat and drier weather can lead to wildfires, w...

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 chat...

Climate change is having major health impacts around the world - which are only expected to increase as our planet gets warmer. These impacts range from heat stroke to the spread of tropical diseases, from hospitals losing power during extreme weather to the effect on our mental health. In this week's show, Graihagh Jackson talks to two doctors from Malaysia and Egypt about the challenges the medical sector faces, as well as possib...

The Climate Question panel discuss how to make homes - and ships - better for the climate. Plus, what about our own carbon footprints? And are oceans or forests better at storing carbon?

Answering your head-scratchers are Justin Rowlatt, BBC climate editor; Akshat Rathi, senior climate reporter for Bloomberg News and host of Bloomberg's Zero podcast; and Caroline Steel, presenter of BBC CrowdScience.

Got a question for the next liste...

Tropical rainforests cover around 6% of our planet, yet they're home to more than half of the world’s species. They're also one of our planet’s most vital defences against climate change. But a new report shows how our tropical forests were ravaged in 2024 - and the Amazon rainforest was one of the worst impacted.

Host Graihagh Jackson finds out why, speaking to BBC climate reporter Esme Stallard and Colombia’s former environment m...

David Attenborough's new documentary argues that our oceans have been underexplored and undervalued. Could protecting our seas not only help biodiversity, but fix the climate too?

Keith Scholey, one of the directors of "Ocean With David Attenborough", tells The Climate Question how the world’s seas are at a critical turning point. Many countries have pledged to protect a third of the world’s oceans, and the film’s creators hope it w...
