It could be the clean fuel of the near future- for homes and for heavy machinery. Lord Bamford, head of JCB, is betting that it will power the next generation of emission-free tractors, diggers and loaders. Tom Heap meets the JCB team and discusses the pros and cons of hydrogen with climate scientist, Tamsin Edwards of King's College, London.

The Nobel prize-winning author Mario Vargas Llosa’s latest novel revolves around the lies, schemes and vested interests that infected the development of Latin America. In Harsh Times (translated by Adrian Nathan West) a CIA-supported military coup topples the government of Guatemala, but the idea that the country was a Soviet satellite is shown up as manipulated fiction. Llosa tells Tom Sutcliffe about the murky tales of Cold War conspiracies that dominated at the time, and their legacy today.
Natalia Sobrevilla Perea is Professor of Latin American History at the University of Kent and looks at the impact of the Cold War proxy battles on countries like Peru, Bolivia, Guatemala and El Salvador. She highlights the power of the drug barons and the current Peruvian government’s war on corruption. Her research focuses on how historical events have set the stage for contemporary debates about how Andean nations should be governed and how to define citizenship.
But what of the land before outside interference? Peru: a journey in time is the latest exhibition at the British Museum and showcases the civilisations and societies that rose and fell in the remarkable landscapes of the Andes mountains. On display will be objects from the early culture of Chavin in 1200 BC to the Incas in the 16th century. The co-curator Jago Cooper says the ancient Peruvian societies had their unique approaches to economy, gender, power and beliefs, and they thrived against the odds up until the Inca conquest by the Spanish.

A French minister told people to eat fewer croissants at this year?s COP26 summit, after the menu said the carbon cost of the pastry was higher than that of a bacon roll, even if it was made without butter. Tim Harford investigates whether this claim could be true, and how the effect of food on climate change can be measured.

At times it can feel as though we’re in the middle of a generational war, with the baby boomers battling the much maligned post-millennials. But in Generations the Director of The Policy Institute at King’s College London, Bobby Duffy explores just how far when we’re born determines our attitudes to money, sex, politics and much else. He tells Andrew Marr how the data from more than 40 countries unravels many of our preconceptions.
Born since the mid-1990s, Generation Z is the first age group never to know the world without the internet. It is also the generation most often pilloried in the press as replete with woke snowflakes, obsessed by identity. But the linguist Sarah Ogilvie believes that young people have much to teach about how to live in the digital world. She is the co-author of GenZ, Explained which seeks to draw a more optimistic and nuanced portrait of this generation, and delves into their specific cultural language.
Olivia Yallop is young enough to be part of the digital generation and in Break the Internet she explores the royalty of the attention economy, influencers (such as Molly-Mae Hague, pictured above). In the new media landscape online celebrities dominate and their value is estimated in billions of pounds. Yallop traces how online personas are built, uncovering what it is really like to live a branded life and trade in a ‘social stock market’.

When Professor Martin Schweinsberg found that he was consistently reaching different conclusions to his peers, even with the same data, he wondered if he was incompetent. So he set up an experiment.
What he found out emphasises the importance of the analyst, but calls into question the level of trust we can put into research.
The internationally-renowned artist Ai Weiwei explores the origins of his creativity and political beliefs through his own life story and that of his father. In 1000 Years of Joys and Sorrows, translated by Alan H. Barr, he looks back at the blighted life of his father Ai Qing, once China’s most celebrated poet before he was banished during the Cultural Revolution. Ai Weiwei tells Tom Sutcliffe about his own journey to becoming an artist and how his work has been shaped by living under a totalitarian regime.
The Professor of Political Theory, Lea Ypi, understands only too well growing up in a repressive Communist state – she was born in Albania, the last Stalinist outpost in Europe. In her memoir, Free: Coming of Age at the End of History she describes how the isolated world of her childhood was swept away. But also how the promised freedoms after the fall of the Berlin Wall quickly turned sour.
The pianist Kirill Gerstein was born in the former Soviet Union, but is now an American citizen based in Berlin. His career and musical heritage is similarly international, and he plays all around the world. Gerstein considers what creative freedom has meant to some of his favourite composers – from Viktor Ullmann to Shostakovich – who produced great art during times of intense political upheaval.

Who is counting, why are they counting, and what are they are counting?
These three questions are important to ask when trying to understand numbers, according to Deborah Stone, author of Counting, How We Use Numbers to Decide What Matters.
In this episode, she explains how different ways of totting up can have real-world consequences.

Arnold Schwarzenegger is the former governor of California and one of America's most influential green voices. He's also one of the biggest movie stars in the world and a big fan of the innovators, activists and entrepreneurs featured in the previous 39 episodes of this series. In this final programme, the Terminator star discusses his favourite ideas from the series with Tom Heap and looks forward to the crucial climate change talks in Glasgow in November.
‘Outside my work the thing I care most about is gardening’, wrote George Orwell in 1940. In Orwell’s Roses Rebecca Solnit explores how the writer’s love for growing things, especially flowers, seeps into his work. She reflects on how he uses pleasure, beauty and joy as powerful acts of resistance. And how far these can counter the political and environmental challenges we face today.
The father of science fiction, H.G. Wells was also driven by a desire to reform the society he lived in at the turn of the 20th century. The biographer Claire Tomalin brings to life his early years in The Young H.G. Wells: Changing the World. He was born into poverty and achieved international fame, but never lost his boundless curiosity for the world around him, and the possibilities of science to change it.
The journalist Peter Hetherington asks why land reform is not higher on the government’s agenda. In Land Renewed he looks at the competing elements in the reshaping of the countryside and aiding nature’s recovery, including protecting valuable farmland, encouraging more local food production, re-wilding and ‘re-peopling’ remote places. But he argues it needs a wider vision to re-work the countryside for the benefit of all.
Tom Heap discovers fresh ways to quantify greenhouse gas emissions with help from satellites, artificial intelligence and former US Vice President Al Gore.
Emissions data from companies and countries can be inaccurate, incomplete or sometimes just plain deceitful. The team at Climate TRACE, led by Al Gore, have devised innovative ways to calculate accurate emissions data from power stations, factories, ships and even planes. That data can be used to reveal unexpected sources of carbon dioxide and methane and to provide independent figures for international negotiations on climate change.
