Environmental journalist Edward Struzik returns to the Land and Climate Podcast to discuss his latest book, Animal Diaspora: Decoding Ice Age Mysteries to Reveal the Future of Migration. The book reconstructs migration patterns of animal populations from the last Ice Age, finding that millions of mammoths, reindeer, and early humans moved into the Americas after rapid periods of warming and cooling temperatures displaced them from their habitats. In conversation with Bertie, Edward Struzik gives

Content advisory: this episode describes events that listeners may find distressing.Five years ago, in the small coastal town of Palma, Mozambique, 500 fighters from the ISIS-affiliated al-Shabab group stormed a community living and working beside a multi-billion-dollar natural gas field part-owned by France's biggest company, TotalEnergies. As insurgents swept through Palma, they beheaded and shot men, women and children indiscriminately, among them construction workers contracted to build

2026/09/04

Colombia is one of the most unequal countries in the world when it comes to agriculture and land ownership. Violence in the Colombian countryside has often cleared the way for corporate agriculture to move in, displacing land once held by small farmers, known as “campesinos”, and transforming it into new frontiers for capital. “Armed conflict undermines the productive systems of campesinos, which reinforces the corporate food regime and the modernisation of agriculture”, says Dr Jaskiran Kaur...

2026/08/28

With five and a half years of content, The Land and Climate Podcast has an overwhelmingly large back catalogue. We have always aimed to produce evergreen episodes, however, and many of our older interviews still have insights and relevance in 2026. This is why we are launching a new offering, alongside our usual programming, called 'In Review'. Alasdair and Bertie pick one topic per episode, playing highlights from our favourite interviews and discussing recent developments. First up:

Is reducing energy use a political taboo?

The Land & Climate Podcast ·

2026/08/07

Solar and wind power is growing worldwide, but so is electricity consumption: as a result, renewables are often only added to the energy mix, rather than replacing fossil fuels. Reducing energy demand would make net zero more achievable, but it recieves far less attention than decarbonisation efforts. This may be due to a perception that managing energy demand would be politically unpopular, requiring governments to make radical interventions into people's lifestyles and spending. Oliver Broad,

Is geoengineering a security threat?

The Land & Climate Podcast ·

2026/07/24

Geoengineering research is growing, as scientists look for increasingly radical means to protect humanity from the disastrous impacts of global heating.Less publicly, concerns are also building about the use of these techniques for geopolitical disruption or control. Technologies such as solar radiation management (SRM) and stratospheric aerosol injection (SAI) are controversial amongst climate scientists: they could buy us time through a temporary cooling effect, but they would not actually stop

In her latest book, Ann Pettifor argues that we are not governed by politicians or diplomats, but “by wealthy and powerful players in markets based in Silicon Valley, Wall Street, the Chicago Mercantile Exchange and the City of London.”These players, she says, largely either ignore the threat of climate breakdown, or see it as a struggle for resource control. The “unregulated actions of private actors and institutions in global markets have

Can ocean technologies combat climate change?

The Land & Climate Podcast ·

2026/06/26

Most net zero policies and major scientific models rely on carbon dioxide removal (CDR) to limit global heating to 2℃. The most commonly known methods include afforestation, bioenergy with carbon capture, and direct air capture - but various proposals are emerging for ocean-based CDR technologies. Could marine CDR offset emissions from sectors that cannot easily decarbonise, or are the costs and risks too great? Bertie sat down with oceanographer David Ho to discuss these questions, shortly after he

Was Chinese history shaped by climateflation?

2026/06/12

The 17th Century Little Ice Age wreaked havoc on weather systems and economies around the world. In China, extreme cold and intense droughts led to soaring grain prices, and as food security collapsed, so did the centuries old political regime of the Ming dynasty.Alasdair speaks to Tim Brook about his groundbreaking book ‘The Price of Collapse: The Little Ice Age and the Fall of Ming China’. They discuss the importance of climate changes in the rise and fall of empires, and the lessons that can be

What is the history of extinction?

The Land & Climate Podcast ·

2026/05/29

Scientists warn we are in an age of mass-extinction. Entire species are ceasing to exist at unprecedented rates. When did this age begin, and when did humans start to confront their impacts on ecosystems and living populations? Sadiah Qureshi explores extinction as ‘unnatural’ and inherently political, by placing humanity at the centre of her latest book, 'Vanished: an Unnatural History of Extinction'. In conversation with Bertie, she traces the history of the concept of extinction in

Have plastics co-opted the circular economy?

The Land & Climate Podcast ·

2026/05/15

Last year, multilateral negotiations for a Global Plastics Treaty broke down after countries failed to agree to limits on plastic production - as opposed to simply regulating plastic waste. This distinction between 'upstream' and 'downstream' measures to tackle plastic pollution is a point of contention between industry and campaigners, with the plastic lobby favouring recycling advocacy over efforts to curb plastic production. Alasdair discusses this issue with Dr Rob Ralston,

What happens after a country's electricity infrastructure is destroyed by war? Following the US invasion of Iraq in 2003, Turkish conglomerate Karadeniz Holding had an innovative idea: if ships could be retrofitted as floating power plants, they could be quickly deployed to countries in crisis, then moved elsewhere again when needed.

How do trade unions influence climate policy?

2026/04/17

The labour movement has contributed to climate and environmental policy for decades, and developed the concept of a ‘just transition’. Despite this, the relationship between unions and climate policymakers can be strained, with concerns from both parties about how the other will approach job losses from phasing out fossil fuels. How has trade union policy on decarbonisation developed over the decades, and what are union leaders’ perspectives on more radical academic arguments, such as the need to

2026/03/20

With the recent 'AI Boom', the energy demand of computing has risen dramatically. As generative artificial intelligence (AI) chatbots such as Chat GPT, Claude, Copilot and Grok become more mainstream, tech companies are racing to build and power new data centres - the physical 'computer factories' that store and process our information and online services. This new infrastructure is significantly increasing greenhouse gas emissions - but tech companies argue that the climate

Why is wellbeing ignored in climate modelling?

2026/03/06

Climate change is making the lives of many more difficult. Tens of millions of people are already displaced by weather events each year, and studies show that climate breakdown drives mental and physical health crises, increased conflict, drought, and food insecurity, among many other challenges. So why do leading climate models primarily measure impacts on Gross Domestic Product (GDP) rather than human wellbeing? Inge Schrijver joins Alasdair on the podcast to discuss her new research ...

Are the Iran protests a climate story?

2026/02/20

Long before the recent economic crash and brutal killings of protestors in Iran, the country faced enduring environmental crises. Depleted dams and dried rivers have left stretches of land exposed, sending dust clouds across the country and severely degrading air quality. Last October, President Masoud Pezeshkian warned that the capital, Tehran, may have to be evacuated due to the country's water bankruptcy. Have these problems contributed to the civil unrest this winter? Bertie puts th...

In September 2025, Vladimir Putin acknowledged that the climate crisis presents “risks” for Russia that are “very dangerous”. Though not unprecedented, such statements differ from other Russian government messaging that has argued climate threats are overstated as part of a Western agenda, or that climate change could benefit the country.
