The Climate Question

Cycling is healthy, cheap - and as modes of transport go, they don’t come much greener. Worldwide, transport is responsible for nearly a quarter of all carbon emissions, with road transport alone accounting for 75% of that. But so far, most discussions on greening the transport sector have focussed on electrifying our cars, trucks and buses – overlooking the vital role that bicycles could play in the climate transition. In fact, experts say that we’re unlikely to meet our short-term climate goals without more people getting on their bikes. So what needs to change to make that happen? We look at what’s been done on streets of Bogota, New York and Kampala to get more people cycling across the world. Presenters Kate Lamble and Neal Razzell are joined by: Janette Sadik-Khan, former Transport Commissioner of New York City Henk Swarttouw, President of the European Cyclists Federation and World Cycling Alliance Amanda Ngabirano, Lecturer in Urban Mobility at Makerere University, Kampala Jaime Ortiz Mariño, architect and organiser of the first ciclovía event in Bogotá Producer: Zoe Gelber Reporter: Laura Ubate in Bogotá Researchers: Immie Rhodes and Louise Parry Series Producer: Alex Lewis Editor: Richard Fenton-Smith Sound Mix: Tom Brignell

Along almost every tropical coastline you can find the tangled roots of mangrove trees, a natural barrier against extreme weather. They are also one of the most powerful weapons we have for fighting climate change. Mangrove forests are six times better at capturing carbon than tropical forests. But in the last 40 years up to a third of mangrove forests worldwide have disappeared.Joining presenters Kate Razzell and Qasa Alom to discuss where our mangroves have gone are: Leah Glass, Technical Advisor for Blue Carbon at Blue Ventures Andre Aquino Senior Natural Resources Management Specialist, World Bank, Indonesia Producer: Dearbhail Starr Researchers: Immy Rhodes and Louise Parry Reporter: Fyneface Dumnamene Series producer: Alex Lewis Sound Mix: Tom Brignell Production Co-ordinators: Siobhan Reed and Helena Warwick-Cross Editor: Richard Fenton-Smith

Scientists estimate that peatlands around the world hold about 350 billion tonnes of carbon. The tropical peatland of the Congo Basin – known as Cuvette Centrale - are thought to store the equivalent of 20 years of US fossil fuels emissions. BBC Africa Correspondent Andrew Harding has been up to his neck in it, witnessing the work being done by scientists to protect it and what might threaten its future. He also hears a warning from Environment Minister, Arlette Soudan-Nonault, about the choices the Republic of Congo faces between preserving the peatlands and making use of its resources to provide a living for its population.We find out how one simple lesson learned in Indonesia is being shared with countries in Africa and South America to help keep a global promise to protect tropical peatlands. It’s not just about promises though – financial experts explain why persuading richer countries to pay cash for “wasteland” could be good for all of us. Presenters Kate Lamble and Neal Razzell are joined by: Dr Daniel Murdiyarso, Principal Scientist with the Centre for International Forestry Research, Indonesia Prof Kevin Chika Urama, Chief Economist, African Development Bank Sara Jane Ahmed, finance advisor to the V20 Group of climate vulnerable countries.

Reduce, reuse, recycle is a familiar mantra the world over. Recycling has been described as ‘one of the easier climate-friendly acts” that individuals can do. A recent poll found that, globally, most of us believe that recycling is the single best thing we can do to tackle the climate crisis. But there isn’t much mention of “reduce” and “reuse”. This week, presenters Kate Lamble and Neal Razzell explore how successful the world’s recycling system really is, visiting Port Klang in Malaysia where huge swaths of the globe’s recycling gets sent only to end up... well, listen and you’ll find out! Kate and Neal will also learn how climate friendly recycling really is and whether there are other more important actions we can take to improve how we manage our waste.

We often talk about the physical costs of climate change; the economic fallout, the effect on livelihoods and damage to the earth. But all of the changes to our world caused by global warming will have an effect on our minds, our mental health too. Earlier this year the mental health challenges caused by rising temperatures and extreme weather events were spotlighted in a report by the UN’s climate science body, the IPCC. Anxiety, stress, post-traumatic stress disorder, and even suicide, are all predicted to increase as the world heats up. Jordan Dunbar looks at what this means for people living on the front line of climate change, including examples from Nigeria, India and the Philippines. Joining Jordan to discuss the mental health challenges facing a warming world are: Dr Brandon Gray – Clinical Psychologist, World Health Organisation Dr Gesche Huebner Senior Researcher University College London, Energy Institute Dr Paolo Cianconi Psychiatrist Catholic University of Rome, Department of Neurosciences Presenter: Jordan Dunbar Reporter: Rajesh Joshi Producer: Jordan Dunbar and Sarah Wild Production Coordinators: Sophie Hill, Siobhan Reed Series Producer: Alex Lewis Sound Engineer: James Beard Editor: Richard Fenton-Smith

Long term climate policy has long been at odds with short-term politics. As numerous countries head to the polls this year, we visit Brazil, Australia and the United States and see how climate policy is being used as a political tool to divide voters. During recent the elections in Australia – a country with some of the world’s highest emissions per capita – experts believe that experiencing the effects of climate change first hand brought the need for action up the agenda, leading to the unseating of the climate sceptic Liberal National Coalition. We hear from a follower of Brazilian president Jair Bolsonaro, who believes that the country’s own deforestation figures are fake. Meanwhile, in the US, we look at how the Republican party’s position changed from the 2008 presidential elections from proposing climate policies to denying that man-made climate change is real.Kate Lamble and Neal Razzell are joined by: Kate Walton, political journalist based in Canberra, Australia Kathy Hochstetler, Professor of International Development at the London School of Economics, UK Anthony Leiserowitz, Director of the Program for Climate Change Communication at Yale University, USAReporter: Roberta Fortuna Researcher: Immie Rhodes Producer: Dearbhail Starr Series Producer: Alex Lewis Editor: Richard Fenton-Smith Sound Mixer: Tom Brignell

Recent research shows that levels of Methane gas in the atmosphere are rising rapidly. It is over 80 times more potent as a greenhouse gas than carbon dioxide so poses a major threat to the world’s goal of limiting global warming to 1.5 C. At COP26, over 100 countries signed a Global Methane Pledge to reduce man-made emissions by 2030 – experts say cutting methane emissions is ‘the most powerful lever we have for reducing warming... over the next 30 years’. So what can be done to stop the levels rising further? We hear how farmers in Bangladesh, along with other parts of Asia, are using wetting and drying techniques in rice paddies to reduce emissions; how cows are being fed special dietary supplements with a surprising ingredient: seaweed, but why naturally occurring wetlands are a cause for concern. Presenters Kate Lamble and Neal Razzell are joined by: Xin Lan, Greenhouse Gas Scientist with NOAA and University of Colorado Drew Shindell, Special Representative on Methane Action for the Climate and Clean Air Coalition Ermias Kebreab, Professor at the Department of Animal Science at the University of California, Davis, Humnath Bhandari, Bangladesh country representative, International Rice Research Institute, Producers: Alex Murray and Serena Tarling Researcher: Immy Rhodes Reporter: Akbar Hossain, BBC Bengali Series Producer: Alex Lewis Sound engineer: Tom Brignell Editor: Richard Vadon

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.Jordan Dunbar and Kate Lamble are joined by: Rita Steyn, Contributing Editor at The Marine Diaries and lecturer at University of Tampa, Florida Michael Yap, Marine Biologist and Founder of Seagrass Guardians, Malaysia Dr. Haimanti Biswas, Principal Scientist of Biological Oceanography at CSIR-National Institute of Oceanography, India Dr. Annette Scheffer, Marine Biologist and Lecturer, speaking with us from Antarctica John Kirkwood, Marine Biologist and Expedition Leader speaking with us from Antarctica Researcher: Immie Rhodes Reporter: Mark Stratton Producer: Dearbhail Starr Series Producer: Alex Lewis Editor: Richard Fenton-Smith Sound Engineer: Tom Brignell

China currently has 53 nuclear power plants with plans to scale up significantly in the next decade, while India is planning to build 10 new power plants over the next three years. South Korea’s new government has committed to restarting its civil nuclear programme and even Japan’s prime minister has pledged to resume nuclear power in a country that has long been resistant. Following Russia’s invasion of Ukraine, energy security has now become more of a priority with countries looking for alternatives to Russian gas. And as countries transition to renewable power in an effort to reach net zero by 2050, governments are looking for a stable, green power supply which is lower cost. In the latest IPCC report, all pathways recommended nuclear in some form to mitigate against climate change. After nuclear disasters such as Fukushima in Japan, safety has become an even more pressing issue, both in the region and globally, in the face of a resistant public and to safeguard communities around any power plants. We gained access to the Hinkley Point power plant in the UK which has adapted the design of the reactors to make them safer after what happened in Japan; but the pace of building has been slow and costs have been high. In China, a commitment to build more has led to a coordinated approach in terms of training, the supply chain and funding. But there are challenges ahead.Presenters Kate Lamble and Jordan Dunbar are joined by Changhua Wu, a policy analyst specialising in China's environment, energy, climate change and sustainable development; Diane Cameron, head of the Nuclear Technology Development and Economics Division at the OECD Nuclear Energy Agency; Edwin Lyman, expert on nuclear safety and proliferation; and Director of Nuclear Power Safety at the Union of Concerned scientists in Washington.

There are over 10 million electric cars on the road globally after a decade of rapid growth, representing around 1% of the world’s car stock. But there are questions about whether there is the infrastructure to match. In many countries there are not enough chargers being installed to cope with the number of electric cars being sold. There are also doubts about whether existing electricity grids have the ability to store enough capacity to cope with charging demand and whether the amount of energy required can be fulfilled by green electricity alone.This week we look at Norway, an early adopter to electric vehicles, or EVs, and have been through a quick adaption period in which they improved their electricity grid to support night time charging, as well as improving the network of fast chargers around the country to enable EVs to take their drivers long distances. We then look at Vancouver in Canada has been looking at ways in which they can improve their EV infrastructure, to encourage the public to make the switch away from internal combustion engines. But do they have enough public chargers to serve those without access to their own private driveway?And finally we take a look at how Sub-Sahara Africa is electrifying motorbikes and minibuses. Many rural communities remain off-grid because demand for electricity is so low that it is not financially viable for them to build the infrastructure. For these rural areas, electric vehicles will bring a solid demand for electricity, bringing the potential for companies to make a profit from introducing solar mini-grids to those communities that don’t yet have electricity.
