The amount of carbon dioxide in the atmosphere in 2026 is roughly the same as when, in the very, very distant past, the Earth was between 6 and 8 degrees warmer. If the Earth were to reach those temperatures again, the majority of mammals would go extinct. While we’re not at those temperatures now, the level of carbon dioxide in the atmosphere could cause the climate to accelerate towards planetary conditions that pre-date the dinosaurs. This is the stark warning of this week’s guest, Bill McGuire. A geologist and volcanologist by training, he has spent time as an expert and government advisor on extreme weather events, before becoming an author. According to him, there is no plan for the extreme climactic upheaval that is to come.

The genocide of Palestinians, carried out by the Israeli army with backing from the US and the British state, has lead to an almighty breakdown in public trust in the West. Now more than ever, citizens are turning away from establishment media sources in search of journalism that more closely resembles the world as we see it.  This week on Downstream, Ash Sarkar sits down with Amy Goodman, veteran journalist and founder of Democracy Now!, one of the leading independent media organisations in the US. Goodman is the subject of a new film, Steal This Story, Please!, which documents her storied career covering some of the most consequential moments in American living history. She has confronted sitting presidents, bore firsthand witness to 9/11, survived a firing squad in East Timor and exposed major corporate crime in the Niger Delta. What drives Amy to do the work she does – shining light on humanity’s darkness, decade after decade? How did her Jewish upbringing in Brooklyn inform her work? What does good journalism look like to her? Why does she believe we all need to re-learn the lost art of disagreement? And does she think American democracy can survive? 

Nadia visits reporter and author Hazel Sheffield in her Hastings beach hut to talk about the coastal communities that are reimagining their economies in the face of government neglect and climate breakdown. They talk about the Hastings Commons project, a constellation of community-owned buildings in a deprived part of the town, and the seaside village in Somerset that built itself a £7m art gallery. Hazel’s book, Frontierlands: Britain’s Survival in the Making, is available now.

The summer of 2026 will go down in history books as the hottest, driest and most deadly set of heatwaves Britain has ever experienced. This weather isn’t normal – but it is predictable according to a global consensus of scientists. And yet this summer, according to the science, will be one of the coolest summers we ever have again. Things will only get hotter from here. Beginning his career as an oil-rig engineer before retraining as a climate scientist, Kevin Anderson’s career has been an extraordinary journey. On Downstream this week, Aaron Bastani sat down with him to discuss what has become his life’s work: sounding the alarm on man-made climate change, and on the fossil fuel industry that gave him his start. Just how much has the planet heated, and why? Is the Paris Agreement’s aim of keeping heating to beneath 1.5°C still achievable, or delusional cope? What are the political obstacles to tackling the issue? Having worked with Andy Burnham in Manchester, what does Kevin think he will do on climate, as PM? Is avoiding catastrophe still possible, and if so, how much time have we got to act, before it’s too late?

Nadia, Keir and Jem wonder why humans are drawn to the beach in a weird-left conversation that spans geological deep-time, the birth of surf culture, the politics of faded seaside towns and more, plus music from 808 State and The B-52’s.

In the years since October 7th, the world has been bitterly polarised over how to make sense of the violence. While polling shows that a majority of people do believe Israel’s actions amount to genocide – having witnessed it with their own eyes via their smartphones – it has been woefully hard to find mainstream media outlets in the West prepared to use this language. On Downstream this week, Aaron Bastani sat down with Indian essayist and novelist Pankaj Mishra. His most recent book, ‘The World After Gaza’ takes stock of a world order shattered by the genocide, and a media class unprepared to recognise the truth. In response to these crises, Mishra and colleagues have just launched Equator magazine, pulling together leading writers from across the globe who are unafraid to tell the truth. When did the so-called West first begin to lose standing in the eyes of the rest of the world? Why is the British media class positioned so uniquely close to power, so delusional, and so compromised over Gaza? Will China replace America, in the coming century, as the new hegemonic power? Has it already?

Joshua Citarella built his reputation by mapping synthetic e-deologies of terminally online politics, expressed in memes, micro-disputes and merch drops. Now the artist, Doomscroll host and Do Not Research founder has come to a blunter conclusion: it’s time to lock in. Behind the seeming diversity of online politics, one ideology has already won: the technolibertarianism of the platforms and supply chains that actually make it all run. So maybe it’s time to get serious, tune out the noise, and get back to basics: workers versus capital. This episode is the finale of Do Your Own Research Series 1. We’ll be back soon.

A new consensus has emerged in Westminster, seemingly overnight: we need more defence spending, and we need it now. But the Ministry of Defence has a record for waste that would put Tony Soprano to shame. £13 billion down the drain, since 2010, at the very least. Aircraft carriers that come in late, overbudget, and beset by mechanical failures. IT systems that cost millions, and are wildly out of date. No other government department could get away with it. But the arms trade spends billions of dollars on greasing the wheels of political consent. They employ armies of lobbyists, print reams of analysis, and bribe politicians the world over to keep the war machine funded. The result isn’t just a crisis of corruption. It’s a threat to our survival as a species. Andrew Feinstein is a former-minister in the South African government, turned investigative reporter. He is the executive director of Shadow World Investigations, and serves on the board of Declassified UK. And in 2024, he stood against Keir Starmer in Holborn and St Pancras. He joins Ash Sarkar on Downstream to lift the lid on how the arms industry really works, and tell us about his political journey.

The American empire is in crisis – and there is a new generation of more vocal critics coming from the right. So what do JD Vance and Tucker Carlson actually believe about American power? James Pogue has reported on empires and their decline for years, from West and Central Africa, where Wagner Group picked over the corpse of French neo-colonialism, to California’s secessionist fringe and the absurdities of Washington. He also happens to be one of the closest observers of JD Vance, who is just a heartbeat from one of the most powerful positions in the world. The president’s real job is keeping the machine running: asset prices up, markets juiced, the war economy fed. Can anyone actually change that? And would we even want them to try, if it’s as ideologically peculiar and dangerous as Vance? Get the map: novaramedia.com/dyor Music by Iglooghost.

We live in times of crisis. But perhaps none of the crises affect so many people in the here and now, as the housing crisis. Solving it could provide the skeleton key to unlocking so many of society’s problems. Despite this, decades of successive governments in the UK have failed to bring housing under control. The social contract which told us that if we worked hard all our lives, we can own a home and be secure in retirement, has been completely broken. To discuss the crisis in Britain and beyond, Aaron Bastani sat down with Peter Apps. He is an award-winning journalist who knows the field of housing – its failures and its potential fixes – better than almost anyone. He wrote an article about the threat of flammable cladding a month before Grenfell caught fire. How has housing policy shaped Britain in the last 50 years? Who did more to damage the housing system, Labour or the Tories? Is more housing supply always the solution? And why is no one talking about the crisis facing our ageing population, one million of whom will be in housing insecurity and poverty by 2030?
