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 chatting to those who’ve made the switch to electric as well as those who haven’t. Akshima Ghate from the RMI Foundation and Louise Ribet of C40 cities explain why these small vehicles are so popular and what countries like India and others gain from encouraging electric uptake. From better air quality and healthier children to energy security and manufacturing expertise, there are many benefits beyond mitigating climate change.

Every year, the great migration sees hundreds of thousands of wildebeest, gazelles, zebras and antelopes migrate from the Serengeti plains in Tanzania to the Maasai Mara in Kenya, in search of water and juicy grass. But rising temperatures and unpredictable weather are changing this epic animal journey dramatically. It’s the same for great white sharks, which are being spotted in areas where they’d never normally live. Tanzanian safari guide Neema Amos takes us into the Serengeti to explain why the wildebeest migration is so important. And shark expert Trisha Atwood reveals how these changes affect not just the animals, but our fight against climate change itself.

As governments and industry find ways of reducing emissions to keep climate change under control, some people are taking responsibility for their own carbon footprints. In this episode, Graihagh Jackson explores some different ways of living a green life – from setting up an eco-friendly commune in Denmark, to making small adjustments to our lifestyles in cities such as London. Graihagh also talks to one of the UN's top experts on the social aspects of fighting climate change: what's the right balance between action by individuals and action by governments?

As climate change makes the world hotter, some cities have appointed "Chief Heat Officers" to try to improve their response to record-breaking temperatures. Graihagh Jackson speaks to two women who have done the job in Freetown, Sierra Leone, and Monterrey, Mexico. What does their role involve? What solutions are out there? And do they get enough funding? Plus, Umaru Fofana reports from Freetown on the extreme heat gripping the city. Umaru talks to locals forced to sleep outside because of the temperature, despite risks to their health and safety. And he also investigates a new piece of building design that might help people living in informal settlements.

It may sound like the stuff of science fiction, but the idea of assembling giant solar farms in space and then beaming the renewable energy back down to Earth is gaining real life traction. Some advocates have claimed it could supply all the world’s energy needs by 2050. But how would these solar farms be assembled, how much fuel and money would it take to blast them into space in the first place, and how would we safely beam their energy back to Earth? In 2023, Sophie Eastaugh and Luke Jones spoke to Sanjay Vijendran, in charge of space-based solar at the European Space Agency, learn about the history of the idea from Rick Tumlinson, founder of SpaceFund, and hear words of caution from Dr Jovana Radulovic, head of mechanical and design engineering at Portsmouth University in the UK. Plus, French astronaut Thomas Pesquet describes life on the International Space Station and how it’s powered.

Graihagh chats to the BBC World Service's Global Story podcast about a plan for a super-category for storms. Is climate change making them so powerful that we need a new grade?

At the big COP climate summit last December, more than 20 countries pledged to triple global nuclear capacity by 2050 to help cut carbon emissions. The signatories included familiar nuclear names such as the US, France and Japan...but also newcomers, like Ghana. Although Ghana doesn’t currently have any nuclear power plants, president Nana Akufo-Addo says he wants to build one or two by 2030. So why is this African nation turning to nuclear? How will it pay for the multi-billion-dollar power plants? And will this help fight climate change? Presenter Graihagh Jackson is joined by: on-the-ground reporter Thomas Naadi; Dr Michael Bluck, Director of the Centre for Nuclear Engineering at Imperial College London; and Dr Kacper Szulecki, research professor at the Norwegian Institute for International Affairs.

Global temperatures have already increased by around 1.3C above pre-industrial levels, but this warming is not spread evenly across the planet. The Arctic, despite being one of the coldest regions on Earth, has become a hotspot for global warming. Local temperatures there are rising as much as four-times faster than in other parts of the world. This rapid warming is unsettling the delicate environmental balance, causing significant ice loss – with implications for both the region and the wider world. In a previous episode on the Arctic region, Graihagh Jackson explored the impact that climate change was having on the people – and ice sheet – of Greenland. In the second part of The Climate Question's focus on the High North, she explores the implications of an increasingly ice-free region on global politics, military relations, and trade. Guests: Mathieu Boulègue, consulting fellow at Chatham House and global fellow at the Polar Institute of the Wilson Centre Julie Brigham-Grette, professor of Earth Sciences in the Department of Earth, Geographic and Climate Science at the University of Massachusetts Amherst Malte Humpert, senior fellow at the Arctic Institute Amund Trellevik, Norwegian journalist with Investigate Europe Producer: Ben Cooper Series Producers: Simon Watts and Alex Lewis Editor: China Collins Sound Engineer: Tom Brignell Production Coordinators: Debbie Richford, Sophie Hill and Jacqui Johnson

2024 will see billions of voters head to the polls in a record-breaking year for elections. It follows 2023 – another record-breaking year for the climate... so could global warming impact the way people vote? Or will it be eclipsed by the other big issues that dominate news headlines, like inflation and the cost of living, healthcare, education, and jobs. In this episode, presenter Graihagh Jackson hears from voters all over the world, and dives into research examining their priorities and what motivates them when they’re at the ballot box. She also finds out how climate change policies affected the outcome of recent elections in the Netherlands and Australia.

Lake Sihwa in South Korea is home to the world’s largest operating tidal power station, using the tides to generate enough power for a city of half a million people. This regular rise and fall of the seas is more predictable than sunny or windy weather and can be forecast years in advance. Nine thousand miles away in Northern Ireland is Strangford Lough. A narrow inlet leading to the mighty Atlantic Ocean means it’s one of the world’s best sites for harnessing tidal energy. The fast and strong currents have led to the world’s first commercial-scale tidal energy power station being built here. But now that’s being decommissioned. The technology for harnessing tidal energy has been around for more than half a century and the potential to create energy from the sea is huge. Yet tidal power only accounts for a tiny proportion of the global renewable energy mix. Presenter Graihagh Jackson finds out what’s holding tidal power back.

The future of flying might depend on used cooking oil, plants and green electricity. Sustainable aviation fuels, known as SAF, are made from less carbon-intensive processes and renewable sources. Airlines are touting them as the key to decarbonising flying. The aviation industry has pledged to move from 2.5% of all global CO2 emissions to net zero by 2050 – with these alternative fuels being the cornerstone of the strategy. However, there’s little SAF actually being produced, it, and it’s much more expensive than fossil fuels. Can the technologies really take off? Climate Question host Graihagh Jackson investigates, with reporting from the BBC's Monica Miller in Malaysia and Singapore.

The deal at this year's COP conference in Dubai is being hailed as "historic" because it's the first time nearly 200 countries have all acknowledged the role of fossil fuels in Climate Change. But critics says the agreement is riddled with loopholes, and that the pledge to "transition" from oil, gas, and coal is too weak. So who's right? And what difference will this year's discussions make? Graihagh Jackson gets the low-down from COP from BBC Climate Editor Justin Rowlatt, and she talks to three leading experts on Climate Change diplomacy.
