President Trump has made sweeping changes to America's policies on climate since being sworn in 100 hundred 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? In this show, 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 & 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.

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.

Graihagh Jackson talks to mothers from India, Kenya and the UK about how climate change is affecting women's decisions about whether to have children and how to raise them.

Graihagh Jackson and guests tackle more of your intriguing questions: Why do we use big wind turbines instead of small ones? Can petrol and diesel vehicles be converted to EVs? And can floodwater be captured and stored?

In the debate 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,

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.

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:

NOTE: The speech made by President Jimmy Carter mentioned in the programme, was made in 1977 not 1974, as stated.

Graihagh Jackson and BBC Climate Reporter Esme Stallard discuss the latest news from around the world - including a row at Britain's prestigious Royal Society about whether to expel Elon Musk, the latest numbers on the state of glaciers and a report from Germany on the future of the country's massive coal industry. Plus, Caroline Steel from the BBC's Crowdscience podcast has been finding out how Norwegians are protecting themselves from the growing number of encounters with polar bears.

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.
