The United States will no longer play global policeman, and no one else wants the job. This is not a G-7 or a G-20 world. Welcome to the GZERO, a world made volatile by an intensifying international battle for power and influence. Every week on this podcast, Ian Bremmer will interview the world leaders and the thought leaders shaping our GZERO World.

Renewable energy and the case for climate optimism with Bill McKibben

The world is in the midst of the fastest energy transition in human history. Environmentalist and author Bill McKibben joins Ian Bremmer to explain why renewables aren’t just a climate fix, they're an opportunity to reshape the future.

Is the clean energy revolution finally here? Over the past few years, the world has experienced a sudden and overwhelming surge in renewable energy installation and generation, outpacing even the most optimistic predictions from experts. This week on the GZERO World Podcast, Ian Bremmer talks to with Bill McKibben, an environmentalist and author, about the stakes and scale of the global energy transformation. His new book, "Here Comes the Sun," argues renewables aren’t just a climate fix—they’re a political and economic opportunity.

Costs from solar and wind have dropped so dramatically in the last 36 months that they’re now the cheapest way to produce electricity worldwide. And energy independence has become a national security issue amid so much global instability. But while China and Europe are pushing ahead in the race to power the future, the Trump administration is doubling down on fossil fuels. What happens if the US puts the brakes on clean energy, just as the rest of the world hits the gas? Or rather... plugs in the solar battery? Do we risk being left in the dark?

Europe's wake-up call, with Alexander Stubb and Kristalina Georgieva

The GZERO World Podcast heads to Davos, Switzerland for the World Economic Forum this week for a look at transatlantic relations and how President Trump’s second term is reshaping the global order. Uncertainty and tensions were high this week as Trump doubled down on his desire to control Greenland—before announcing a deal with NATO over the Danish territory’s future and walking back tariff threats. Ian Bremmer spoke with Finnish President Alexander Stubb on the sidelines of Davos to discuss the future of the transatlantic relationship, Arctic security, the war in Ukraine and why, despite so many geopolitical challenges, Europe is more united than ever.

“Trump has a different type of way of doing foreign policy, and a lot of it is actually quite effective,” Stubb says, “ I feel that the US, Ukraine, and Europe, we're now on the same page.”

Then, Bremmer sits down with Kristalina Georgieva, Managing Director of the International Monetary Fund, for a look at the surprising resilience of the world economy. Georgieva says there are four key reasons why the IMF upgraded its global growth forecast for 2026. They also discuss the importance of independent central banks and Trump’s push for more control over Fed policy.

Trump's second term–one year in, with Stephen Walt


It’s been a year since President Trump returned to office, this time with fewer constraints, a better understanding of how government works, and a much more muscular view of US foreign policy. This week on the GZERO World Podcast, Harvard’s Stephen Walt joins Ian Bremmer to help answer a simple question with complicated answers: what kind of presidency is he building this time around?

Over the past year, we’ve seen a dramatic expansion of presidential power and a rewriting of America's role in the world. There’s been a retreat from multilateral institutions, targeting of long-standing allies, and a view of global politics where great powers dominate, and weaker ones fall in line. It’s a big departure from 80 years of the postwar order America spent building and leading. How much more will change by the time he leaves office?

“A lot of the things that Trump has done are not surprising in terms of where he's trying to take things. People knew he was going to get tough on tariffs. They knew he was going to be harsh on Europe,” Walt says, “I'm surprised not by the direction things have gone, but by the speed and scope by which things have changed.”

Venezuela after Maduro with Sen. Gallego and Frank Fukuyama



The United States has pulled off a stunning operation in Venezuela, capturing longtime strongman Nicolás Maduro and bringing him to New York to face federal charges. For President Trump, it was a dramatic show of force, executed without US casualties and framed as proof that American dominance in the Western Hemisphere is back. But once the dust settles, far bigger questions remain. What happens when a regime falls but the system behind it stays intact, and who takes responsibility for what comes next?
