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.

Graihagh also chats to Tom Di Liberto, a climate scientist who was recently fired from America's National Oceanic and Atmospheric Administration (NOAA).

Hydroelectricity is the world’s biggest source of renewable energy, and dams have long been a popular - if controversial - way to fast-track development and boost economies.

Jordan Dunbar is in Thailand, a country that has been transformed by hydropower. He meets Thais who've been helped by dams, and those they’ve hurt. And he finds out how a warming world could put the future of hydropower in jeopardy.

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.

Guests: Ulrico Grech-Cumbo, CEO Habitat XR in South Africa John Zelenski, Professor of Psychology at Carleton University in Canada Gabriel Ngale, Nairobi Region Conservation Education Head, Wildlife Clubs of Kenya

As the UN's shipping body, the International Maritime Organization, meets to decide on a pivotal levy that will tax ships for using polluting fuels, host Graihagh Jackson and BBC Climate Reporter Esme Stallard discuss whether this will be enough to cut the industry's significant carbon emissions. From the Port of Rotterdam, we find out how the industry is already trying to reduce its carbon footprint. And are alternative shipping fuels really as green as it's claimed.

We dive into the issue, along with more of April's climate news. The BBC’s Climate Editor Justin Rowlatt speaks to one of COP30’s top officials, a new study on carbon-gobbling forests in China and the latest on India’s heatwave.

Bangkok is a mega city of more than 10 million people, the economic powerhouse of Southeast Asia and one of the world’s most visited cities. Billions of dollars worth of new luxury real estate is planned as huge skyscrapers pierce the sky and become back drops to some of our biggest film and TV series. But there’s a problem, Bangkok is sinking; in fact, it’s one of the fastest sinking cities in the world.

To make matters worse, climate change is affecting both sides of the city: sea levels are rising in the Bay of Bangkok, and water levels are increasing in the mighty Chao Praya river.

Jordan Dunbar is in the Thai capital to find out: How do you stop a mega city sinking?

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 efficiency could save us money on our bills too - especially in a warming world, where many countries will need air conditioning just to function. So does this crucial area in the fight against climate change need a rebrand. And could it even become sexy?

In a programme first broadcast in 2024, Presenter Jordan Dunbar talks to: Dr Rose Mutiso - Research Director Energy for Growth Hub Prima Madan – Director, Cooling & Energy Efficiency, International Natural Resources Defence Council, India Kofi Agyarko – Director of Renewable Energy and Energy Efficiency, Ghana Energy Commission Thomas Naadi – BBC Correspondent, Ghana

Climate change is usually associated with hotter weather, but experts say that in Mongolia it's making the country's cold snaps even harsher. Can Mongolian nomads survive much longer in extreme winter conditions known as "dzuds"? Or will the loss of their livestock and livelihoods force herders to abandon a way of life that dates back millennia?

Graihagh Jackson finds out more about the situation on the ground from Mongolian reporter Khaliun Bayartsogt, and explores possible solutions with Khulan Dashpuntsag from the UN-funded ADAPT project.

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 bringing billions of euros of investment into the Hungarian economy and creating tens of thousands of jobs. One city in particular – Debrecen – the country’s second biggest, is becoming an epi-centre for battery production. The Climate Question’s Jordan Dunbar has been to Debrecen to find out who’s benefitting from the green gold rush. He speaks to local people and businesses about their hopes and fears as their city is transformed.

How can you have a successful relationship with someone if you believe passionately in climate action, but they don’t? The fate of our planet can be a divisive, emotive, even frightening issue. It’s something that’s tearing more and more couples and families apart, experts have told us.

It’s not easy getting past those differences with the ones we love, but it is possible. We speak to a couple, as well as a mother and daughter, to find out how. And we ask whether the way we talk to our loved ones about climate change might offer important lessons on how we discuss the issue more broadly.

Presenter Graihagh Jackson is joined by:

Daze and Antonia Aghaji, from London Caroline Hickman, researcher at the University of Bath in the UK and psychotherapist Mohini and Sam Pollock, from Campbell, California
