The Climate Question

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: theclimatequestion@bbc.com

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 Orleans, and how we can build cities that can stand up better to more extreme weather events. They chat to Prof Reggie DesRoches, an engineer who was on the ground in the aftermath of Katrina to help find out what had gone wrong. His work specialises in adapting infrastructure for natural disasters, including developing innovative materials and practical techniques that might just help us adapt to more violent storms. Can we build a world where hurricanes can't kill?

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 rainforest. Plus, China has just started work on the world’s biggest hydroelectric dam. It’s a huge 167-billion dollar project to bring power from Tibet to Hong Kong. The dam will increase Beijing’s use of renewable energy, but comes with a potential environmental cost, as well as the risk of creating tension with China’s neighbours. Laura Bicker gives us some staggering facts and figures about the dam – as well as an explanation of how fish can use “ladders”. Got a climate question you’d like answered?

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 chemicals.BBC China Correspondent Laura Bicker has seen this environmental impact first hand on a visit to the rare earth hubs of Bayan Obo in northern China and Guanzuo in the south. She's been speaking to locals about the benefits this booming industry brings and the damage that it can cause. BBC Climate and Science Reporter Esme Stallard also joins Jordan Dunbar to chat about why rare earths are so valuable and the state of greenhouse gas emissions in China. Plus, she's got an update on a climate satellite that's gone missing in space!

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, while retreating snow lines can put pressure on winter skiing trips. For their part, popular destinations in the Caribbean and the Pacific face another challenge - from rising sea levels. Host Graihagh Jackson asks how holiday-makers and the travel industry can adapt to a changing climate.

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 minister, Susana Muhamad.Presenter: Graihagh Jackson Producers: Beth Timmons and Diane Richardson Sound Engineer: Dave O'Neill and Tom Brignell Editors: Simon Watts and Lisa Baxter

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 will push global leaders to deliver on their promise at this year's UN conference on oceans. The documentary also includes some of the most detailed footage ever captured of bottom trawling, a widespread fishing method that damages the seabed. In this episode we ask why we know so little about the ocean? And why the largest part of our planet been under-protected for so long?

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 BBC's US environment correspondent, Carl Nasman, BBC climate editor Justin Rowlatt and Zerin Osho, director of the India programme at the Institute for Governance and Sustainable Development based in Washington DC.

A growing body of scientific evidence from across the globe suggests that a love of nature could inspire us to be more sustainable – something scientists say is more necessary than ever given the climate crisis. The more we connect with nature, the more likely it is that we're willing to protect it. It’s never too late to build that bond, but studies show that outdoor adventures as children make us more likely to be eco-heroes later on. Getting outside isn't just a win for the planet. Science has shown that increased time in nature yields a plethora of positive impacts, ranging from reduced crime rates and enhanced family bonding to improved physical health, peace of mind, child development, and overall well-being. The Climate Question celebrates Earth Day by speaking to children at a wildlife club in Kenya, a virtual reality film director in South Africa whose ambition is to make up-close encounters with animals accessible for everyone, and a leading nature connection expert in Canada.
