In 1985 British scientist Jonathan Shanklin and colleagues published a study that shocked the world. The study revealed a hole in the Earth’s atmosphere right over Antarctica. It had been caused over time by chemicals known as CFCs, used in things like fridges, air conditioning units and aerosol cans. These were destroying the layer of ozone in the stratosphere which protects us from most of the sun's ultraviolet radiation - without it, cases of skin cancer would soar. Less than two years after ...

From the Aztecs to the Zoroastrians, humans have always prayed for rain. We’ve tried dances, ritual sacrifices and even blowing up the sky to boost rainfall. This might sound crazy but desperate times call for desperate measures. Climate change is making people desperate again, in some regions droughts are becoming more frequent and pervasive whereas in others floods threaten livelihoods and cities. We have already affected our weather cycle but can we control it? Many governments have turned to...

In rural North East Spain, proposals to build hundreds of new wind turbines have sparked opposition and divided communities. And it isn’t only Spain. There has been resistance to wind power projects across the world from Mexico to the US. Opposition groups have succeeded in delaying, and sometimes cancelling, the construction of new wind farms. To move away from fossil fuels, we will need a huge expansion in renewables. But will wind power be able to meet this challenge in the face of local oppo...

The Ocean, it covers more than 70% of the surface if our planet, it provides us with food, medicine and even influences the weather. For years its also helped to mitigate the effects of climate change. Since the 1970’s over 90% of atmospheric warming caused by green house gas emissions has been absorbed by our Oceans. But this comes at a cost. Overtime their temperatures have risen and this has had disastrous impact on some of our most important ecosystems. Join us on a dive into the world of wa...

Shopping online is nothing new but with the rise of influencer culture, livestreaming, and social commerce buying stuff has never been easier. Research suggests that the production and use of household goods and services is responsible for about 60% of global greenhouse gas emissions. So is influencer culture making us buy more - contributing to climate change? Or is it more complicated than that? In this programme we hear from Nigerian influencer Noble Igwe and eco-influencer Rosie Okotcha. As ...

We know from The Climate Question back catalogue, solving climate change is a knotty problem which does not lend itself to quick fixes. But in this programme a panel of experts discuss whether there could be any easy wins on climate change such as putting solar panels across the Earth’s deserts and changing what we eat. Presenter Neal Razzell is joined by: Rebekah Shirley - Director of Research, Data & Innovation at World Resources Institute (WRI) Africa, Peggy Liu - Director at Project Draw...

Since the 1990s, air flight has made the world a smaller place. In one 24-hour period you can fly to the other end of the globe. In an hour you might be able to skip the traffic and fly to the other end of your country. But this convenience comes at a cost….to the climate. Aviation accounts for somewhere between 2 to 5% of the world’s emissions. And as the world’s desire to travel proves insatiable, the number of planes in the sky each day is only increasing. The aviation industry has aspiration...

The development of agriculture some 12,000 years ago changed the way humans live. As technologies have developed we’ve become more and more efficient at producing large amounts of food and feeding an ever growing population, often with the help of synthetically produced nitrogen fertiliser. These fertilisers can damage ecosystems. They also produce a potent greenhouse gas called Nitrous Oxide which is 265 times more warming than carbon dioxide. It’s estimated that the manufacturing and use of th...

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 goal...

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 Adv...

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...

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 ...

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...

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 unseat...

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...

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 altern...

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 energ...

The renowned climate scientist and IPCC author Maisa Rojas has been making headlines after being appointed as Chile’s new Minister for the Environment. She has pledged to deliver a green, sustainable and resilient future – and a ‘just transition’ to renewables from an economy that has to date been reliant on mining, forestry and agriculture. The legacy of General Augusto Pinochet has cast a long shadow over Chile, so one of the first hurdles is a vote on a new constitution in July which would ea...

When talking about climate change, the term net zero has become popular with politicians over the last few years. More than 130 countries have now pledged to go net zero to help slow global warming. Reaching net zero means reducing the amount of emissions as much as possible and removing any that remain from the atmosphere. We hear from communities in South Africa, where the government plans to reach net zero by 2050. But the country is heavily tied to coal and faces several challenges around em...

Hundreds of youth activists travelled to Glasgow, Scotland, to have their voices heard. As we approach the halfway point between COP26 and COP27- to be held in Egypt - we want to know how young people are feeling about progress made. We speak to Maria Reyes from Mexico, Edwin Namakanga from Uganda and Farzana Faruk Jhumu from Bangladesh, who all attended the conference. Is the world on course to protect nature, curb emissions and generate the necessary finance to help poorer nations adapt? Helpi...

As more countries launch more rockets into orbit for commercial and scientific reasons, the space industry is experiencing rapid growth. It’s on the verge of an even greater increase as space tourism takes off. The International Space Station is now open to tourists and private companies have developed rockets that can be reused – all meaning more launches into space. But rocket exhausts contain particles that can affect the climate. What are the potential impacts and is it time to apply the bra...

In the wake of Russia’s invasion of Ukraine, parts of the world are so dependent on Russian gas that they have no option but to continue to buy it. This week’s episode looks long term plans for improving energy security, particularly in Europe where the biggest focus is on increasing renewables. Whilst this sounds like great news for the climate, Europe only accounts for 10% of the worlds’ emissions. For fossil fuel rich countries like the United States, energy security policy will mean pumping ...

The Russian invasion of Ukraine has been met with harsh financial sanctions. These have come from North America and Europe. The US and Canada have also banned Russian oil and gas, but Europe has found itself unable to do so - even as natural gas prices soar. The EU receives 40% of its natural gas from Russia, and for many countries, if they turn it off, the lights will go out and they’ll be unable to keep themselves warm. As a result European money continues to pay Russia for its natural gas res...

Scientists say extreme weather is intensifying and becoming more frequent because of climate change and the impacts are causing huge losses. People living in Brisbane and other parts of eastern Australia dealt with those impacts recently, when heavy rain fell for days - destroying thousands of homes and at least 22 people are known to have died. Authorities declared it a once in a-100-year-event, making it the second disaster of its kind in the same area in just 11 years. While insurers face los...

As climate change brings rising temperatures, droughts and shifting patterns of rainfall, animals are adapting to keep pace. Bird’s bodies are growing smaller, their wingspan longer, lizards are growing larger thumb pads to help them grip more tightly in hurricane strength winds, beak size is changing. We visit the Galapagos, where evolution was first discovered by Charles Darwin, and investigate the many ways animals are adapting their behaviour and physiology to survive the impact of climate c...

"A brief and rapidly closing window of opportunity” is how a new major climate change report from the UN described the effect of rising emissions. Already 40% of the world's population is "highly vulnerable" to the impacts, according to the latest report from the International Panel on Climate Change. And it’s all happening much more quickly than previously thought. Sophie Eastaugh and Jordan Dunbar discuss the findings with a panel of experts. How much more serious do things need to get before ...

The need to be able to store electricity as part of our low carbon future, has increased dramatically as the use of renewable energy has expanded. Both solar and wind energy rely on sunlight and weather, only providing intermittent power. Electric cars need to be able to travel greater distances on one charge and cost less to have mass market appeal. It’s clear batteries are a key - but evolving - technology. Improvements still need to be made to their safety, power and cost. Megawatt batteries ...

We hear a lot about how melting glaciers are contributing to sea-level rise but not so much about the impact inland. In places like Tajikistan, glaciers feed rivers and are a significant water source. As they melt climatologists expect water flows to increase, contributing to a rise in mudslides and floods. But in the long term, the melting ice will lead to water shortages. We look at mountain communities living near glaciers and try to understand what impact this is having now and what might ha...

For nearly a century, governments around the world have measured the health of their economies by a single metric: GDP, or Gross Domestic Product. It measures a country’s economic growth, and over the years has become a shorthand for national progress; a rising GDP is generally understood to mean more people in work, more companies in business, living standards on the rise. Yet, as experts have argued for decades, there is a lot that GDP leaves out. While it measures the value of all goods and s...
