Trains on Trial

Rare Earth ·

2025/09/26

It's 200 years since the first passenger rail journey saw George Stephenson’s Locomotion No.1 travel 26 miles between Shildon, Darlington and Stockton. Environmentalists love trains - making a journey by rail can be up to 80% greener than doing it by car - and there are exciting new inventions hoping to make train travel even greener. But can we pin part of the blame for global warming on the invention of the railways in the first place? Presented by Tom Heap and Helen CzerskiProduced by Beth

The Risk Takers

Rare Earth ·

2025/08/22

Can the insurance industry save the planet? With the nod from insurance companies a must for everything from coal mines to new homes, is the industry ready and willing to wield its power? When huge swathes of Los Angeles were destroyed by wildfire in 2025 the spotlight shone on the insurance industry. Would insurers pay out billions of dollars to rebuild in exactly the same way, in exactly the same place, in a region in which the risk of wildfire is only going to increase?Tom Heap and Helen Czerski

Metals and Minerals

Rare Earth ·

2025/06/20

The transition to an economy based on renewable energy and electric cars needs huge quantities of materials like copper and rare earth metals. Sourcing them can be a problem. Mining damages the surrounding landscape and many of the materials come from unstable regions with poor records on child labour and environmental regulation. Are there alternative materials or do we simply need to consume less? Tom Heap and Helen Czerski investigate.Producer: Emma CampbellRare Earth is produced in

Powering Our Robot Overlords

2025/06/13

Datacentres are big business, and vast numbers of them are being built around the world. In the UK, Amazon has announced plans to invest £8bn over the next five years building new datacentres, £3bn has been spent in the UK by Amazon’s cloud computing business since 2020 and Google is spending millions on a new centre in Hertfordshire. All this data handling is necessary because we're storing more of it and making more complex AI internet searches. The energy cost of this shift is so huge that the

Is Net Zero a toxic brand?

Rare Earth ·

2025/06/06

In 2008 the UK made an all-party legally-binding commitment to reach net zero carbon emissions by 2050. Since then the consensus has broken down and analysts doubt that current government policy has any chance of reaching that goal. Tom Heap, Helen Czerski and an expert panel stress-test net zero. Is it still achievable? Is it even politically possible in a world of trade wars, Trump's anti-environment agenda and the rise of Reform?Producer: Emma CampbellRare Earth is produced in association

Are insects the answer?

Rare Earth ·

2025/05/30

Insects are the quiet engineers of the environment - pollinating our plants, balancing our ecosystems and clearing up our waste. Some insects can digest plastic, and they play a vital role in crop production. At the same time their populations are under threat from pesticides, habitat loss and climate change. In this programme, Helen Czerski and Tom Heap explore the largely ignored world of insects. Could they be the answer to some of the environmental problems we have created? Would eating them

How to Clean Up the Shipping Industry

2025/03/28

The shipping industry is an enormous source of pollution. Ships burn dirty fuel oil that helps contribute to the industry's global carbon emissions and even in port they continue to belch out noxious fumes that pollute the air of many of our major port cities. Tom Heap and Helen Czerski search for the solutions, from a return to sailing ships to new fuels - and even the possibility of ships being more like penguins - with a panel including:Paddy Rodgers, Director (Chief Executive) of Royal

Forever Chemicals

PFAS chemicals are all around us. They're used in frying pans, food packaging and waterproof coats but they have been linked to thyroid disease, liver damage and cancer. The trouble is that PFAS just doesn't go away- these 'forever chemicals' build up in our bodies and the environment.Tom Heap and Helen Czerski look back at the invention of these miracle chemicals, their use in the Second World War and the Space Race and meet Robert Bilott, the American lawyer who held the PFAS manufacturers to

The Hole That Changed the World

40 years ago a hole was discovered in the ozone layer. It provoked an international effort to ban the chemicals that were destroying our protection from the sun. Tom Heap and Helen Czerski are joined by Jonathan Shanklin, one of the team that realised that CFC chemicals used in aerosol cans and refrigerants were helping to create a 20 million square kilometre hole in the ozone layer above Antarctica.

The wolf has mounted an extraordinary comeback. Once hunted to extinction across Western Europe, the wolf has taken advantage of the collapse of the Iron Curtain and the depopulation of the countryside to spread from east to west, reaching the suburbs of Amsterdam and Brussels. Only Britain, Ireland, Malta, Cyprus and Iceland now lack the top predator that haunts our fairytales.Tom Heap and Helen Czerski go face to snout with the wolf to find out the secrets of its success.

For the Arctic, 2024 was the second-warmest year on record, with temperatures rising much faster than the global rate. The region's resources- oil, gas, iron ore, uranium, even diamonds and the rare earth metals used in electric cars- suddenly seem accessible. That's caught the attention of China, Russia and the US, with President Trump, eager to mount a hostile takeover bid for Greenland.In the first of a new series of Rare Earth, physicist Helen Czerski and environment journalist, Tom Heap
