The Climate Question

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...

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...

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,...

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...

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...

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 fi...

The effects of climate change on weather patterns around the world, including seasonal temperatures and rainfalls, are being felt keenly in agriculture – with shifting seasons and varying yields undermining years of habit-formed knowledge and process. Technology experts are helping farmers, including in some of the world’s poorest regions, adapt to the new food production landscape through the use...

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...

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 infect...

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...

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 Si...

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. Hosts Jordan Dunbar and Kate Lamb...

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...

In 2009, the G20 countries pledged to phase out 'inefficient' fossil fuel subsidies, which have long been seen as an obstacle to fighting climate change. But today, subsidies for oil and gas producers are at record levels -- $64 billion in 2021. It’s not just to do with the war in Ukraine. Despite its image as a leader on climate change, the UK is listed as one of the worst offenders for governmen...

The Arctic is warming four times faster than the global average temperature. Ice caps are melting, forcing the indigenous Inuit community living around the Northwest passage to change their way of life. Polar bears and wildlife are losing their habitats and the ability to hunt. Further south, Middle Eastern countries are facing temperatures above 50 Celsius more regularly. We speak to people livin...

Heatwaves are already the most deadly of climate risks. If we don’t keep climate change in check, we’ll experience more of them, reaching even higher temperatures. Already we need cooling to keep our homes, hospitals and workplaces comfortable, our vaccines stable and our food nutritious. As the planet warms up we’ll have even greater need. Currently the cooling industry is incredibly polluting –...

Half of all the energy we use globally goes on heating and cooling. We need heating for all sorts of things; from keeping our homes warm to industry which needs super high temperatures. At the moment, the heat we use is mostly powered by polluting fossil fuels, a huge driver of climate change. But can renewables deliver the high temperatures and a constant supply which are so vital? In this episod...

Extreme weather is becoming even more extreme thanks to climate change. Countless lives are claimed by heatwaves, cold snaps, cyclones, droughts and torrential rains every year around the world. Climate change threatens to make things worse. But the United Nations is spearheading new action to make sure every person on Earth is protected by early warning systems within the next five years. It’s ho...

From climate sceptic to climate campaigner, Sarah Ott grew up in the US surrounded by doubters, listening to out-right deniers. This is the story of what changed her mind. We also hear people’s questions about climate change from Kenya where there’s major drought and we speak to BBC Disinformation reporter Marco Silva on dealing with climate misinformation. Presenter Neal Razzell is joined by: Sar...

Back in 2010, FIFA announced that the tiny country of Qatar would host the 2022 World Cup. It would be the first Middle Eastern country to do so. The tournament has seen thousands of fans travel to see it, with millions tuning in around the world. But it hasn’t been without controversy. The event’s organisers claimed that it would be the first fully carbon-neutral World Cup. A big new solar park w...

The ecosystems of the land and ocean absorb around half our planet warming emissions. But these are being destroyed by human activity. At the same time, climate change is a primary driver of the destruction of these habitats and biodiversity loss. If biodiversity is our strongest natural defence against climate change (as it’s been described), what’s stopping us from doing more to protect it? As t...

What we eat has a massive impact on global warming. Meat and dairy are among the biggest drivers of the climate crisis - creating more planet-warming emissions than all the cars in the world. As we all try to reduce our carbon footprints, it’s not surprising that the global market for meat alternatives that come from soy or pea protein is growing at a huge rate. In fact it’s estimated that by the...

At the start of COP 27 Egyptian President Fattah al-Sisi told the world that it was vital that African countries receive "appropriate support and funding according to the principle of shared responsibilities and burdens”. For years the richest nations have been accused of failing to meet their $100 billion-a-year pledge for funding. It turn out this doesn’t even scratch the surface - a recent repo...

The world has been in Egypt for COP27, the UN’s big climate talks. It’s a country that’s already feeling the acute effects of climate change – temperatures have risen by two degrees since last century, damaging farming and driving up food prices. Tensions are rising, but many are concerned that restrictions on the right to protest and freedom of expression mean that climate change is not getting t...

Last year at the COP26 climate conference in Glasgow, countries made big promises to tackle climate change – by curbing their greenhouse gas emissions and reducing deforestation. But as this year’s COP27 continues in Egypt, we ask whether countries are keeping to their word. Presenters Neal Razzell and Graihagh Jackson are joined by a host of guests at COP 27 in Sharm El Sheikh: The Climate Questi...
