Love of a Cold Climate

Rare Earth ·

2025/12/19

What does the arrival of winter mean for plants and animals? In this programme Tom Heap and Helen Czerski find out how wildlife survives the freezing temperatures and short days of the winter months. In a time of climate change, they also ask how warmer weather patterns are affecting the natural world at this time of year. Do we have to get used to the idea of winters without snow and ice, and will winter scenes of robins on snowy branches and children sledging down hillsides only exist on Christmas

City Transport: Faster, Cheaper, Greener

Rare Earth ·

2025/12/12

How we get around town has never been more political, with controversies over low traffic neighbourhoods and 15 minute cities, and rows about congestion charging and public transport breaking out all over the country. Tom and Helen are in search of the kind of consensus that makes things faster, cheaper and smoother for all of us. What works and what’s been a complete flop? Should we all stop moaning and get on our bikes? Who is the reshaping of traffic flows working - and not working - for? And

Hiding in Plain Sight

Rare Earth ·

2025/12/05

We tend to think of wildlife as something which exists in the countryside or in nature reserves, but in fact there are plenty of plants and animals which thrive in an urban environment. In this programme Tom Heap and Helen Czerski explore the species that live alongside us in our towns and cities - finding out what makes a good habitat for them, asking why they're important, and discovering what advantages they bring to the human population. They're joined by a panel of experts: Professor Dawn Scott

The Evolution of Evolution

2025/12/01

190 years ago Charles Darwin stepped ashore in Falmouth at the end of a five year voyage that would transform the way in which we all think about nature. But how does his work and that of his fellow evolutionary theorist, Alfred Russel Wallace stand up in a world of climate change and habitat destruction?To find out, Tom Heap and Helen Czerski are joined by Sandra Knapp of the Natural History Museum, naturalist and broadcaster Mike Dilger and by Armand Marie Leroi, professor of evolutionary

Fashioning the Future

2025/11/21

Whether you love to express yourself through fashion, or find getting dressed a chore, clothing isn’t optional - and every choice has an impact. So how do our fashion choices affect the environment? Who's paying the price? And - most importantly - how can we do things differently? Can individuals and business rethink how we see clothes to prioritise the planet? Tom Heap and Helen Czerski get beneath the surface on this huge subject with Patrick Grant, presenter of The Great British Sewing Bee,

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

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?

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

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

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?

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?

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
