Climate science and reporting are vital to understanding how our climate is changing and what we can do about it. But false information about climate change spread online is causing big problems. It’s no longer just about saying that climate change isn't happening; it’s increasingly about spreading uncertainty about its causes, its speed and the solutions. That’s making climate misinformation and disinformation harder to spot - and more divisive.

Host Jordan Dunbar is joined by Jacqui Wakefield, global disinformation reporter with the BBC World Service and guests Marco Silva, climate disinformation journalist at BBC Verify and Prof Michael E Mann, climatologist and director of the Center for Science, Sustainability and the Media at the University of Pennsylvania.

Everyone who steps outside can appreciate the value that the natural world brings to our lives. To some people, the idea of placing a monetary value on trees and mangrove forests is wrong because nature and its gifts are priceless. But others say the love of nature has not stopped it from being polluted or destroyed.

The natural world plays a major role in capturing the carbon from our atmosphere. A marketplace now exists where countries and big businesses can pay others to protect their forests, swamps and bogs in return for offsetting their emissions. But several of these schemes have faced scandal and corruption. Could the world’s largest biodiversity conference in Colombia, COP16, help put a stop to that?

Presenters Kate Lamble and Jordan Dunbar are joined by Kevin Conrad, founder, Coalition for Rainforests; Tina Stege, climate envoy, Marshall Islands; Pavan Sukhdev, chief executive officer, GIST

The southern US state of Georgia has received billions of dollars in investment in clean technology, creating tens of thousands of jobs at solar power factories and electric vehicle factories. It is also on the front-line of extreme weather - facing the threat of hurricanes, heatwaves and drought. So will voters in this swing state be considering climate change when they cast their ballots for the US presidential election in November? And how are politicians in Georgia talking about the issue. Jordan Dunbar takes a road trip across the state to find out.

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 power by drilling directly into volcanic magma. And she travels to Germany to visit Vulcan Energy, a company which is combining geothermal with extracting one of the world's most sought-after metals: Lithium. Plus, our reporter in Indonesia tells Graihagh about local opposition to some geothermal power plants.

Engineers across the globe, from China to East Africa and the US, are turning to a new, nature-based solutions to fight floods, which are becoming more likely in many places because of climate change. They’re taking a pickaxe to asphalt and concrete and instead are restoring wetlands, parks and riverbanks, turning our metropolises into so-called ‘sponge cities’. Plants, trees and lakes act just like a sponge, mopping up rainwater instead of letting it pool and eventually flood our homes.

Professor Priti Parikh tells Jordan Dunbar how these spongey solutions have many benefits beyond flooding, encouraging biodiversity, helping our mental health and storing the planet warming gas, carbon dioxide. The BBC’s China Correspondent, Laura Bicker, meets the man who came up with the concept, Professor Kongjian Yu, and visits Zhengzhou, a sponge city in the making. And Katya Reyna tells Jordan how her NGO is helping low-income communities in Portland in the US to ‘depave’ disused car parks, turning them into plant-oases.

Climate change has been tightening its grip on the people of Afghanistan, with flood after flood and drought after drought. It’s considered one of the most vulnerable countries in the world, not just because it’s warming twice as fast as the global average, but because its people’s ability to fight back has been severely hampered by decades of conflict and war. To add insult to injury, Afghanistan has contributed very little to the industrial emissions that fuel the global climate crisis.

Since the Taliban takeover in 2021, financial aid to help locals adapt has drastically dropped, leaving Afghans to take matters into their own hands. But presenters Graihagh Jackson and Barry Sadid hear how the diaspora is helping villages back home to build life-saving dams and protect themselves against extreme weather. And we ask if there’s a way for foreign governments to financially support Afghanistan without legitimizing the Taliban.

The acclaimed US sci-fi author Kim Stanley Robinson is also a star in the world of climate activism because his work often features climate change - on Earth and beyond. Robinson has been a guest speaker at the COP climate summit, and novels such as The Ministry For The Future and The Mars Trilogy are admired by everyone from Barack Obama to former UN climate chief Christiana Figueres. Robinson's books are not just imaginative but scientifically accurate, and some of their ideas have even inspired new thinking about climate-proofing technology. Kim Stanley Robinson has been talking to the Climate Question team.

With more and more people moving to cities, informal settlements are expected to grow. When floods hit these unplanned places, it can be disastrous, as we often don’t know much about them. Crucial questions often remain difficult to answer, like how many people live there, what are the buildings made of, and could they withstand a flood? In the township of Alexandra in Johannesburg, the BBC’s Nomsa Maseko visits a project using drones and artificial intelligence to shed some light on the situation, helping authorities prevent the worst impacts of flooding. And in Porto Alegre in the south of Brazil, we hear how an innovative digital map helped the emergency response – and will soon be available to all for free across the world.

This little-known pollutant is making us sick and driving the climate crisis. It commonly comes from burning coal, diesel or wood and has a habit of getting stuck in people’s lungs as well as causing glaciers to melt. In Nepal, home to some of the world’s most beautiful glaciers, we meet journalist Tulsi Rauniyar, who tells us all about the impact black carbon is having on women and children. She meets Tenzing Chogyal Sherpa, a glacier expert who maps the ice losses in the Himalayas. Zerin Osho from the Institute for Governance & Sustainable Development helps us understand why black carbon is so important - but often forgotten - in the fight against climate change, and how we can change that.

The Paris Olympics are less than a month away. The last games in Tokyo were one of the hottest on record, with more than a hundred athletes suffering heat-related illnesses. And France, the host of this year’s Olympics, is no stranger to heatwaves – the country has seen 23 since 2010.

So how are top athletes training their bodies to not only perform at their best in high temperatures, but also to protect their health? Presenter Qasa Alom heads inside a sweltering, state of the art heat chamber at Leeds Beckett University to find out how one of the fastest marathon runners in Britain, Phil Sesemann, is maximising his chances of success in his Olympic debut.

Other athletes are more used to these conditions. We join India’s top triathlete, Pragnya Mohan, for a training run and hear what it’s like to compete when the thermometer climbs above 45 degrees Celsius.

More and more athletes are adopting heat training strategies in a warming world - but do they affect men and women the same? Dr Jessica Mee, Research Fellow at the University of Worcester tells us about her pioneering research into the impacts of heat on women’s bodies.

As a new play depicts the landmark global climate change agreement, the Kyoto protocol, Jordan Dunbar has a front row seat. He heads to the historic English town of Stratford-Upon-Avon to watch the opening night of the play, Kyoto, at the Royal Shakespeare Theatre. He hears why the writers, Joe Murphy and Joe Robertson decided to dramatize the seemingly slow and tedious action of a global climate change conference. And the duo explain their goal to highlight Kyoto as a ‘parable of agreement’ in a world full of disagreement.

The programme also hears from two veterans of many real world climate change negotiations, including the Kyoto Protocol, the first global agreement to set legally binding targets. Christiana Figueres was responsible for leading climate negotiations as the Executive Secretary of the United Nations Framework Convention on Climate Change and Farhana Yamin provided legal and strategy advice to the leaders of AOSIS, the Alliance of Small Island States at Kyoto and nearly every UN climate summit since. Christiana is now the host of the 'Outrage And Optimism' podcast.

Someone dies every other day protecting the environment, according to data gathered by the campaign group, Global Witness. Even higher numbers of people are attacked or threatened.

To understand why this is happening, the BBC’s East and Central Europe Correspondent, Nick Thorpe travels to the foothills of the Carpathians in Romania, to show us how important the forests there are in fighting climate change, why they’re subject to high levels of illegal logging and consequently, clashes with environmentalists. One activist, Gabriel Păun of Agent Green, describes the numerous and brutal attacks he’s experiences whilst out documenting illegal logging. We also hear from a mother, whose son was murdered when he confronted a ‘wood thief’ in 2019. Laura Furones from Global Witness tells host Graihagh Jackson why this is happening around the world and what we can do about it.

Billions of dollars have been pumped into the promise of a climate-friendly way of producing meat, but is growing a steak in a lab any better for the planet than rearing a cow on a farm? Supporters of the idea say it will dramatically reduce the impact of livestock, which is responsible for about 15% of the world’s planet-warming gases, as well as returning huge amounts of land to nature. But studies suggest cultivating meat in a lab might actually be worse for the planet, at least in the long-run – we put both claims to the test. Graihagh Jackson presents an update of a programme first broadcast in 2023.

China is scouring the globe for the raw materials of the future. How will we be affected? Graihagh Jackson investigates.

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 buildings and infrastructure that make green decisions easier and also help us deal with stress or depression?

Jordan Dunbar hears about examples in the Netherlands and Egypt. Are there win-win options out there that can help the world deal with two of its biggest challenges?

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?

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

In this episode, Graihagh Jackson explores the new field of climate attribution science with leading climatologist Dr Friederike Otto. Dr Otto's team of experts can now rapidly assess to what extent extreme weather events such as heatwaves, droughts or floods have - or have not - been caused by man-made climate change.

Graihagh finds out how this information is becoming crucial for disaster planning and response. She is also joined by BBC World Service disinformation reporter Jacqui Wakefield to discuss how Dr Otto's data can help fight a growing tendency by politicians and journalists to overstate the role of climate change.

In this extra episode, Graihagh Jackson hears from our friends on BBC podcast The Global Story about a case that could change the history of climate activism.

For nearly a decade, a group of elderly women argued that Switzerland’s weak climate policies violated their human rights. Their victory – the first of its kind in the European Court of Human Rights – sets a precedent 46 countries must now follow. The BBC's climate reporter, Georgina Rannard, has been covering the case for years. She shares the women’s personal stories with presenter James Reynolds, while climate lawyer Sophie Marjanac explains what it could mean for those seeking climate justice everywhere.

Corals protect humans and sustain 25% of all marine life. But reefs are under threat from climate change, and mass bleaching events mean that some scientists estimate they could disappear by 2100.

In this episode, Graihagh Jackson is joined by BBC CrowdScience presenter, Caroline Steel. We go to Puerto Rico to see how self-duplicating, carnivorous coral could be the solution. We also speak to the scientist who helped discover what was causing coral bleaching in the first place - back when climate change was commonly denied.

Ammonia has revolutionised the way we produce our food, helping us to grow much, much more... But it’s also helping to grow global greenhouse gas emissions too.

Synthetic fertilisers are actually responsible for around 5% of the planet-warming gases going into the air - that’s more than deforestation.

In this episode, Graihagh Jackson examines this challenge that modern agriculture poses to the climate, and finds out whether it’s possible to cut emissions from fertiliser use without cutting food production at the same time. She’ll also be joined by local reporters in Kenya to hear about innovative projects aiming to tackle this problem and turn farming green.

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.

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.

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?

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.

As the world’s attention turns to this year’s COP summit in the UAE, questions remain about the host country and conference president.

It’s not the first time that an oil-producing country has hosted the climate change summit. But some environmental campaigners are unhappy about COP28 being held in the United Arab Emirates, and the choice of conference president, Dr. Sultan Al-Jaber – the CEO of the national oil company, ADNOC.

However, supporters say that the country is extremely vulnerable to the effects of climate change, so it has as much of a right to host the conference as anyone else. Meanwhile, Dr Al-Jaber boasts considerable experience working in renewables – having previously run the UAE’s renewable energy company MASDAR.

So what’s really going on? To find out more, presenter Graihagh Jackson is joined by:

It's the world's biggest - and most controversial - climate conference. But how does it actually work? And does it make a difference? Jordan Dunbar investigates.

To help get some simple answers to simple questions, Jordan is joined by climate experts- Dr Mosunda Mumba, Secretary General of the Wetlands Convention Professor David Victor of Innovation and Public Policy University of California, San Diego, USA Adil Najim, Professor of International Relations and Environment at Boston University's Pardee school in the United States.

Check out the other explainers in these series including – ‘What Is Climate Change?’ and ‘Why Is 1.5 Degrees Important?’

In his latest Climate Change 101, Jordan Dunbar finds out why 1.5C is the world's target for limiting global warming. Why 1.5 degrees? And what happens if we miss the goal?

Nearly three decades since the United Nations climate talks began, we take a look at what it has achieved when it comes to tackling climate change. We also look towards COP 28 taking place in Dubai and ask what progress can be made at the latest round of negotiations. It’s the only international negotiation on climate change and a unique opportunity to get agreement on how to best tackle global warming – but it has its critics as well as its fans.

As the world faces up to the increasingly apparent effects of climate change, access to accurate information that helps us to understand what’s going on, why, and what we can do about it, is vital. But in its efforts to do this, the science community is facing a growing amount of abuse from people who do not believe what they’re saying. Anger at the science is leading to threats against the scientists in some cases. In this episode, presenter Jordan Dunbar is joined by BBC Verify’s Merlyn Thomas to find out more and are joined by the following guests: Nihan Kalle, BBC Monitoring, based in Istanbul Helene Muri, research professor in climate change at the Norwegian University of Science and Technology.

Greenland is an island covered in a sheet of ice that is over 3km thick in places, containing 7.4 metres of average global sea level rise. Due to climate change, it’s melting at an astonishing rate. We meet some of the people being forced to rapidly adapt their traditional ways of life. And find out why ice loss means sea level rises for elsewhere in the world – but the opposite for the island itself

The Yasuni National Park in Ecuador forms part of the Amazon rainforest and is one of the most bio-diverse places on the planet. It also produces 60,000 barrels of oil per day. In a recent referendum, held as part of Ecuador’s Presidential elections, people voted to stop drilling for oil – including the newly elected President Daniel Noboa. We visit the town of El Coca – the gateway to the park - where the result thrilled people who are concerned about the climate. But many, especially those whose livelihoods depend on the oil industry, feel the opposite. Presenter Sophie Eastaugh speaks to: Lisette Arevalo, reporter in Ecuador Alejandra Santillana, activist with Yasunidos group in Ecuador who campaigned for the vote Fernando Santos, Ecuador’s Energy & Mining Minister Tessa Khan, climate lawyer and cofounder of the Climate Litigation Network, UK Navraj Singh Ghaleigh, Senior Lecturer in climate law at Edinburgh University, UK

This week we hear from listeners about the ways they cope and how they remain positive on climate change. From being involved in a like-minded community, to taking action in everyday ways. Or just knowing that the brightest minds are pushing innovative climate solutions forward every day.

In a wave of negative climate news, it can be easy to feel overwhelmed and uncertain about the future. Climate change is a real threat, and it’s normal to experience worry, but there are reasons to be positive. We hear from a psychologist about how ‘climate anxiety’ is a normal response to the uncertainty around us and from a Libyan climate activist about what motivates her, despite experiencing climate devastation in her own country.

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 impacting the most vulnerable communities.

Surprisingly, Gates remains optimistic and believes the power of human ingenuity will win out with a technology-driven approach in both mitigation and adaptation.

Graihagh Jackson sits down with Mr Gates to talk about his positive outlook and the billions he’s investing in tackling climate change.

In this, the second episode in our spin-off series on Climate Quitters, we invite trailblazers from three different continents to reveal the ups and down, highs and lows of their new lives in climate conscious careers.

In Mumbai, Namita Dandekar swapped a role marketing stock for one of India's largest - and wealthiest - conglomerates for a front-line position with The RainTree Foundation, an organisation that works with rural communities to introduce climate friendly practices into their everyday lives and livelihoods.

In Vihiga County in Kenya, Kevin Makova traded in his job as a schoolteacher to create sustainable employment opportunities for members of the community keen to work in climate and conservation focused jobs.

And in Berkeley, California, Eugene Kirpichov said goodbye to a lucrative post developing AI systems for Google to build a new, global workforce that he hopes will be capable of solving the climate crisis conundrum.

But is the grass always greener - and cleaner - for climate quitters? What are the realities of life on the other side of that leap? And does putting the planet first come at a personal cost?

In this globe-spanning episode, your host, Paul Connolly, probes all three guests for their views and experiences so far - and we go a step further to bring you on-the-ground, in-person reports from the projects based in both India and Kenya.

Bornholm – a Danish island in the Baltic Sea – is trying to go carbon neutral by 2025. It is a lofty ambition that would put the island decades ahead of most countries. This dream has been 15 years in the making; a crash in fish stocks meant Bornholmers had to reinvent themselves and they chose to become ‘the bright green island’. Since then, they have been making biogas from pig manure, building wind turbine after wind turbine, and now they are piloting new ways of storing this renewable energy, including in a battery made of salt.

The island is not just trying to rid itself of fossil fuels – it is also aiming to go zero waste by 2032. Graihagh Jackson teams up with CrowdScience presenter Caroline Steel to explore Bornholm’s double quest to go green.The changes have not just been at top-level – the island’s businesses and 40,000 residents have been encouraged to reduce their climate impact too. Graihagh visits a brewery whose production has gone carbon neutral by capturing CO2 to create the bubbles in its beers, and meets a chef whose Michelin-star restaurant uses locally-sourced food.

And over on CrowdScience, Caroline tackles Bornholm’s zero waste ambition, visiting a project turning used nappies into compost and a glassblower making tableware out of wasted insulin vials. See link below.

Will Bornholm make its bold goals, and what lessons can be learned for elsewhere?

The live music industry is booming. With global growth in concerts and festivals, more and more of us are enjoying our favourite bands and artists live. The music industry now relies on touring for money – encouraging more and more bands to travel and fans to see them. This is causing emissions to soar just like the private jets. So what can be done? Jordan Dunbar discovers the problem isn’t coming from who you might think and that this could be a climate opportunity rather than a problem.

Guests: Ben Pol, Afrobeats star Prof Carly McLachlan, Director of the Tyndall Centre for Climate Research, University of Manchester Jordi Herreruela, Director of the Cruilla Barcelona Festival Luke Howells, Head of Sustainability for Coldplay and Glastonbury Festival Henry Stuart, Co-Founder and CEO of Visualise

The Prime Minister of Barbados, Mia Mottley, has been raising awareness of the impact that climate change is having on small island nations like hers, from the Caribbean to the Indian and Pacific Oceans.

In addition to facing more extreme weather and temperatures, these islands also have to contend with the threat posed by rising sea levels – which, for some islands, is existential.

In this episode, Qasa Alom speaks to reporters in Fiji and the Maldives about what small island nations can do to survive.

Jordan Dunbar introduces The Climate Question's guide to the Climate Change basics - with the help of some friends of the show.

July 2023 has been confirmed as the hottest month ever on Earth. A combination of heatwaves across the Northern Hemisphere, unseasonable warmth in parts of South America and Antarctica, and global sea surface temperatures around 0.51°C above the 30-year average, meant it broke all previous records.

Climate scientists are now poring over the data, including Prof Jim Skea, the newly-elected chair of the Intergovernmental Panel on Climate Change (IPCC). He joins presenter Graihagh Jackson to discuss how worried we should be, and the challenges ahead as he takes up the most important role in global climate science.

Have you thought about quitting your job because of climate change?

Research shows more and more people are worried about their career’s impact on the planet. So this week The Climate Question hears from four people from around the world who’ve taken the plunge and done it.

Luke Jones meets an air steward who's swapped flying for teaching; a restaurant critic who's become a tree-planter; a fossil fuel company engineer who's switching to working in renewables; and a multinational CEO turned sustainable business campaigner.

Funeral rites are steeped in culture, tradition and faith, with most of the world opting for cremation or burial. However, with new research now revealing the carbon impact of established funeral choices, more people are questioning their cost to the climate.

With alternatives such as ‘water cremation’ and ‘eco-burials’ becoming available, will people start to consider another way?

Presenter Jordan Dunbar hears about initiatives in India to modify traditional funeral pyres, calculates the climate cost of the most common choices, and hears from Archbishop Desmond Tutu’s daughter, Rev. Mpho Tutu van Furth, about her surprise at her father’s final act on earth.

Climate change has been tightening its grip on the people of Afghanistan, with flood after flood and drought after drought. It’s considered to be one of the most vulnerable countries in the world, not just because it's warming twice as fast as the global average, but because its people’s ability to fight back has been severely hampered by decades of conflict and war. To add insult to injury, Afghanistan has contributed very little to the climate crisis. Since the Taliban takeover two years ago, financial aid to help locals adapt has drastically dropped, leaving Afghans to take matters into their own hands. Presenters Graihagh Jackson and Barry Sadid hear how the diaspora are helping villages back home to build life-saving dams and protect themselves against flood and drought. And we ask if there’s a way for foreign governments to financially support Afghanistan without legitimising the Taliban.

Scientists say an El Nino weather event has started. Its effects will be felt everywhere in the form of heavier rainfall in some parts of the world and deeper droughts in others. What's the link with Climate Change? And is it making it harder for us to prepare?

On this week's edition of The Climate Question, Graihagh gets a briefing on El Nino from a leading expert; we travel to Peru to meet the coastal communities on the front line; and we hear how ancient civilisations not only learned to deal with El Nino, but managed to use it to their advantage.

The journey from catwalk, to wardrobe, to landfill is getting shorter and shorter. Our demands for fast fashion mean around 100 billion garments are produced every year. We’re buying more, then wearing them less often. Many will end up in the trash. Not only that, there’s been a big growth in clothes being made out of synthetic materials originating from crude oil. In this updated edition, we ask: can fashion cost less to the climate? and how much progress is the industry making? Speaking to Kate Lamble and Sophie Eastaugh are- • Vanessa Friedman, New York Times Fashion Editor • Lily Cole Fashion model, actress and podcast host ‘Who Cares Wins’ • Phillip Meister, Quantis Sustainability Consulting • Claire Bergkamp, Textile Exchange • Sonya Bhonsle, Global Head of Value Chains, CDP.

Mia Mottley, Prime Minister of Barbados, is on a mission to fight climate change through a radical scheme to reform the international financial system.

Called the Bridgetown Initiative, her plan aims to transform global institutions such as the IMF and the World Bank – freeing up billions, maybe even trillions of dollars, for poorer countries that are struggling to cope with the impacts of a hotter planet.

Presenter Graihagh Jackson is joined by the BBC’s Climate Editor, Justin Rowlatt, who interviewed Prime Minister Mottley at a crucial climate finance summit in Paris. With time running out in the battle to keep the world below the 1.5C warming threshold, we find out more about her plan, how it works and the progress being made.

With the Ukrainian counter-offensive underway, Sophie Eastaugh looks at the climate damage caused by the conflict there and by the recent civil war in Tigray, Ethiopia. Sophie speaks to Lennard de Klerk, a Dutch specialist in carbon accounting, who’s just published the most comprehensive analysis yet of the greenhouse gas emissions caused by the fighting in Ukraine. For her part, an environmental researcher in Kyiv tells The Climate Question her country may have an opportunity to build back greener once the war is over.

The programme also hears from farmers in Tigray about how a region once praised internationally for its reforestation efforts is now losing tree cover at an alarming rate.

And this edition of The Climate Question looks more broadly at the carbon footprint of militaries around the world, speaking to Professor Neta Crawford, one of the leading experts in the field.

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.

The impacts of climate change are already being felt around the world. Research shows that some groups are disproportionately affected. Women already face many socioeconomic, cultural, and political inequities, with those living in areas heavily impacted by natural disasters related to climate change, such as floods, drought, and coastal erosion, enduring even worse outcomes. So what can be done to address this?

Billions of dollars have been pumped into the promise of a climate-friendly way of producing meat, but is growing a steak in a lab any better for the planet than rearing a cow on a farm? Supporters of the idea say it will dramatically reduce the impact of livestock, which is responsible for about 15% of the world’s planet-warming gases, as well as returning huge amounts of land to nature. But studies suggest cultivating meat in a lab might actually be worse for the planet, at least in the long-run – we put both claims to the test. Plus, ten years on from the unveiling of the world’s first lab-grown meat, we ask why it’s still only available to buy at one restaurant in Singapore, and only on Thursdays.

If you are planning a trip, but you want to check the climate impact before choosing how to get there, then beware. Google has been seriously underestimating the carbon footprint of plane flights, and overestimating that of some train journeys. And its calculations don’t just appear in its search results, but also feed the sites of more and more online booking companies, like Skyscanner and Booking.com. To be fair, carbon footprints are actually very hard to get right, as the BBC’s Climate Editor, Justin Rowlatt, discovers on his own trip to Rotterdam. On the way out, he takes the Eurostar high-speed train, whose carbon emissions depend on the weather over the North Sea that day. On the way back he catches a plane, whose climate impact… also depends on the day’s weather conditions over the North Sea. So what is Google doing to fix its methodology and can we trust carbon footprint calculations at all? And do passengers even really care that much about the environmental impact of their journey, or should they be made to pay for it directly?

The idea of cities where everything you need on a daily basis can be reached within a quarter of an hour by foot or bike has grown in popularity in recent years, as local authorities adopt more sustainable approaches to urban planning. In theory, by having work, shopping, education, healthcare, and leisure all within a short distance could reduce dependency on cars, improving personal health and lowering carbon emissions. But the idea of adapting cities in this way hasn’t been universally-welcomed.

Many blame our obsession with economic growth as being one of the biggest drivers of climate change. The United Nations is currently looking at options for what might replace Gross Domestic Product (GDP) as the world’s primary go-to indicator of success, taking into account factors including sustainability and the natural environment. If this happens, it would be the biggest shift in how economies are measured since nations first started using GDP in 1953, 70 years ago.

Wind and solar power will play a crucial role in curbing climate change, but what happens to all the worn-out turbines and photovoltaic panels once they are past their best?

Most wind turbine blades are almost impossible to recycle, and solar panels are very expensive to disassemble, but efforts are under way to prevent a possible renewable waste mountain.

Presenter Graihagh Jackson hears how old wind turbine blades are being turned into everything from bridges to flowerbeds, and we visit one of the world’s only solar panel recycling facilities. Plus – what’s the carbon footprint of a wind turbine or a solar panel in the first place?

Plus we hear from listeners Prateek, Alex and Elle.

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?

Sophie Eastaugh and Luke Jones speak 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.

In 1856, an American woman called Eunice Newton Foote discovered that higher levels of carbon dioxide would warm the planet. But credit for discovering climate change was given to someone else who made the same discovery three years later. We celebrate Foote’s role in early climate science by recreating her little-known experiment and asking if there are some voices that continue to be overlooked in climate science today – and how we overcome these climate blind spots?

With rolling blackouts and huge waste disposal issues a regular occurrence in large parts of Sub-Saharan Africa, we look at how green tech start-ups offer smart, climate-friendly ways to solve the issues holding the region back.

In Malawi, our repórter Peter Jengwa meets Admore Chiumia, whose company Green Impact Technologies turns waste into energy.

In Zimbabwe, the BBC’s Shingai Nyoka visits AI entrepreneur Leroy Nyangani who’s come up with a way of making solar energy more financially accessible, while also solving a big problem of energy access in the country where, almost 70% are not connected to the grid and blackouts are the norm.

Audrey-Cynthia Yamadjako from the African Development Bank outlines a new scheme designed to support green SMEs on the continent.

Presenter Luke Jones is joined by the BBC’s Karnie Sharp who was raised in South Africa. They discuss how, with proper support, green solutions to everyday problems may unlock Africa’s economic and human potential.

Worsening energy blackouts are crippling South Africa. They’re being caused in part by an over-reliance on ageing coal-fired power stations which can’t produce enough electricity. The government has an ambitious plan to rapidly build up solar and wind power by opening up the grid to private providers. But it’s facing opposition from the coal lobby.

Will this electricity crisis be the thing that finally pushes South Africa to implement its climate plan? And can it be implemented in a way that treats all South Africans equally, and doesn’t unfairly benefit a rich minority?

Some oil and gas giants are being pushed by shareholders to adopt more climate friendly strategies.

An environmental law charity is suing the directors of a global oil company, arguing their climate strategy is not adequate to meet current targets, supported by other shareholders. Elsewhere, a group of investors in another fossil fuel giant, recently unseated multiple board members in an effort to force a change of direction.

How effective is this form of activism?

Our warming world is changing the geographical distribution of several animal species. Mosquitoes have been able to colonise new regions, places where they haven’t been found before including Afghanistan and countries in Europe.

According to the World Health Organisation, dengue fever is the most critical mosquito-borne viral disease in the world. Globally there’s been a 30-fold increase in infections in the last 50 years.

But is there a way to prevent the spread of the disease?

Record-breaking temperatures in the Alps in Europe have led to a disappointing ski season so far. Some slopes have been more brown than white, while others have been forced to close all together. Many worry this is a bad omen for the whole industry – which employs thousands globally.

This is part of a wider trend of unpredictable weather. Some ski resorts are trying to adapt, by making artificial snow for example, but these short-term measures aren’t always sustainable.

It’s predicted that the Alps will have 25% less snow by 2050, whereas resorts in Arctic Sweden are forecast to stay colder for longer. Could the northern country become skiing’s last resort, or will the industry have to fundamentally change to survive?

Natural gas is often seen as an environmentally friendly alternative to coal, yet it’s a fossil fuel and gives off climate warming emissions when burned. On the internet there are many adverts suggesting that natural gas is a clean and green way to reduce emissions. We investigate whether these adverts mislead the public as to whether gas is really ‘green.’ Presenters Graihagh Jackson and Marco Silva are joined by: Pep Canadell, Executive Director of the Global Carbon Project & Chief Research Scientist at CSIRO Naomi Oreskes, Professor of the History of Science and affiliated Professor of Earth and Planetary Sciences at Harvard University Former Senator, Mary Landrieu, co-chair of ‘Natural Allies for a Clean Energy Future’

The ocean covers over 70% of the Earth’s surface and can hold more than 150 times the amount of carbon dioxide as air. Around a quarter of CO2 emissions created by human activity each year is absorbed by them. From phytoplankton to whales to seagrass meadows, we explore how this happens. And in climate news, we hear about the wildfires and drought affecting Chile.

India has made a lot of climate pledges in the last couple of years. They’ve had mixed reviews. Some have applauded the country’s ambition – including committing to a net zero target - while others argue it’s still too reliant on coal, the dirtiest of fossil fuels. India is already facing the brutal impacts of a warming planet and, with a population of around 1.4 billion, its energy demand is huge – and growing. But there are reasons to be optimistic. We travel to a rural area near Mumbai to hear about the benefits of solar energy and get a temperature check from BBC Marathi’s Janhavee Moole on what people are discussing locally.

We also speak to two experts to better understand how we can rate India’s commitments compared with other countries as well as the barriers it could face as it transitions to a greener economy.
