China is winning the clean energy race
As the world speeds up the transition to renewables and away from fossil fuels, China is betting bigger than anyone else on the energy technologies that will power the world for decades to come. Environmentalist and author Bill McKibben joins Ian Bremmer on GZERO World to talk about Beijing’s wholehearted embrace of clean energy compared to the US. It’s not just that they’re manufacturing solar panels or putting up wind farms, McKibben says, they’re investing in a technology that will transform the global economy.
Energy demand is rising, driven in large part by data centers that power AI, and McKibben argues that the only way to meet that demand is with cheap, clean energy. While it’s true China still burns large amounts of coal, increasingly it’s used as a second or third tier power source because of the cost compared to solar and wind. China’s investment in renewable energy gives them a competitive edge in technologies that will reshape the balance of power—literally and figuratively.
“China become the world's first electro state,” McKibben says, “They're learning how to use that flood of cheap clean energy to run everything around them.”

Will the clean energy revolution leave the US behind?
Over the past decade, renewable energy has exploded. Technology is improving. Costs are plummeting. This is now the fastest energy transition in human history. But just as the world goes all in on renewables, the US is doubling down on fossil fuels. Does it risk being left behind in the race to power the future? Environmentalist and author Bill McKibben joins Ian Bremmer on GZERO World to discuss the sudden and overwhelming surge of clean energy installation and generation over the past two years, China’s push to dominate the renewable market, and whether the Trump administration’s policies will put the US at a disadvantage.
The White House has cancelled funding solar and wind projects and is pushing other countries to buy more oil and gas, but McKibben says the scale and pace of the global energy transformation is just too powerful to ignore. McKibben’s new book, "Here Comes the Sun," argues that renewables aren’t just a climate fix—they’re a political and economic opportunity to reshape our future. He has no doubt that 30 years from now, we’ll run the planet on sun and wind simply because of economics, but also warns the world will face serious problems if it takes that long to get there
“Fossil fuels become harder to get over time. Renewable energy is the opposite,” McKibben says, “We now live on a planet where the cheapest way to make energy is to point a sheet of glass at the sun.”

Will Trump's energy policies set back climate progress?
President Trump has made no secret of his distaste for wind and solar and preference for fossil fuels. His administration has canceled subsidies for renewable projects, lifted drilling restrictions on federal land, and is pressuring allies to buy more American oil and gas. On Ian Explains, Ian Bremmer breaks down the reality of the energy transition and whether US policies will slow down global progress in moving toward a renewable future.
No matter what the White House says, the incentives for renewables are hard to ignore. From Texas to Saudi Arabia, India to China, governments all over the world are embracing solar and wind not just for the planet, but for economic and security reasons. Clean energy is now the cheapest power source almost everywhere. And, amid rising instability, energy independence has become a safety and security issue. You can’t embargo the sun. No one controls the wind. Fossil fuels still matter, but the question is no longer if the world will transition. It's how fast.

How AI will revolutionize medicine with Siddhartha Mukherjee
Listen: Nearly 1 in 2 men and 1 in 3 women in the US will be diagnosed with cancer, and 1,700 people die from it every day. Disparities persist—Black women are 40% more likely to die of breast cancer than white women—and treatment costs remain crushing for many.
On the latest episode of the GZERO World podcast, Ian Bremmer talks with world-renowned cancer researcher and Pulitzer Prize-winning author Siddhartha Mukherjee about the future of medicine—and why artificial intelligence might finally tip the scales in the decades-long war on cancer.
Cancer remains the second leading cause of death in the US, killing nearly 1,700 people every day. But Mukherjee says AI is already reshaping the field, from radiology and diagnostics to identifying new carcinogens and designing entirely new cancer drugs. “Every time we do this in collaboration with a machine,” he explains, “the machine learns it, and it learns it forever.”
In a wide-ranging conversation, Mukherjee breaks down three major areas where AI is advancing medicine: patient care, data mining, and generative drug development. He also weighs in on early cancer detection, how inflammation may hold the key to understanding new carcinogens, and why this moment may be the most hopeful in half a century of cancer research.

50 years of the war on cancer
We've been fighting a war on cancer for over half a century—from Nixon’s 1971 National Cancer Act to the promise of cutting-edge AI therapies today. Ian Bremmer reflects on how that war is going.
The numbers are still grim: nearly 1 in 2 men and 1 in 3 women in the US will be diagnosed with cancer, and 1,700 people die from it every day. Disparities persist—Black women are 40% more likely to die of breast cancer than white women—and treatment costs remain crushing for many.
But there’s progress. Survival rates have more than doubled since the 1960s, and new technologies, especially AI, are opening doors researchers couldn’t imagine a decade ago. For Ian, it’s personal. Both of his parents died of cancer. “If you haven’t had it yourself,” he says, “you know someone who has.” But for the first time in decades, there’s real hope that science may be gaining the upper hand.

In Milei's Argentina, a fight for indigenous land
In Argentina’s Patagonia region, Indigenous Mapuche communities are clashing with President Javier Milei’s government over rights to their ancestral lands. Facing a deep financial crisis, Milei sees Argentina’s vast natural resources—minerals, oil, timber—as central to economic recovery. But the Mapuche, among the country’s strongest voices fighting for environmental protection, are being evicted from land they’ve lived on for over 14,000 years. On GZERO Reports, Will Fitzpatrick travels to Patagonia to interview Mapuche community members about the legal fight they say threatens Argentina’s unique biodiversity and indigenous culture, as well as their survival.
Land disputes between the Mapuche and the Argentinian state have existed for decades, but after the Milei government revoked a key law that protected Indigenous territories at the end of 2024, officials began an aggressive eviction campaign. Recent raids and accusations of arson have escalated tensions, and many Mapuche fear state power is now being wielded to push them off resource rich territory.

The rise of impunity–and its human cost
What happens when global norms collapse and no one is left to enforce them? On GZERO World with Ian Bremmer, International Rescue Committee president and CEO David Miliband warns that we are living through what he calls an “Age of Impunity,” where power is exercised without accountability, and civilians in conflict zones from Syria to Ukraine to Gaza are paying the price. “The Age of Impunity is becoming the Age of Cruelty,” Miliband says, as rights guaranteed under international law are ignored and no one is holding the powerful to account.
Miliband highlights findings from the Atlas of Impunity, an annual index published by the Eurasia Group, that tracks accountability across 170 countries. The data shows not only extreme cases of impunity in war-torn regions but also surprising results in advanced democracies like Canada, the US, and Nordic countries. Still, there are some signs of progress. For Miliband, the challenge is clear: it will take a massive push from governments, civil society, brave civilians, journalists and human rights advocates to reverse the retreat of accountability and uphold basic principles of human rights.

What (or who) will replace USAID?
As Washington pulls back from its decades-long role as the world’s leading aid donor, the humanitarian system is facing what David Miliband calls a “very big shock.” On GZERO World, the International Rescue Committee president and CEO tells Ian Bremmer that the US has historically been the anchor of the global aid system, contributing nearly $4 out of every $10 aid dollar. But amid the cancellation of USAID and a dramatic pullback in foreign funding, vital programs are now closing and the impacts are being felt all over the world.
Who–or what–could step in to fill the gap? Miliband says China isn’t interested in large-scale humanitarian aid, focused instead on economic development though initiatives like Belt and Road. Europe, meanwhile, is stretched thin by war in Ukraine and pandemic debt. The Gulf States and Japan are debating their role, but the scale of US funding remains unmatched. The result, Miliband argues, is “sucking sound” of money leaving the system, leaving the world’s poorest to pay the price.
“The US was the anchor of the global aid system,” Miliband explains, “When you pull an anchor in choppy waters, the boat rocks and the passengers get seasick. That’s what’s happening at the moment.”
