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.”

In 1971, President Nixon declared a “War on Cancer.” Fifty years and billions in research later, the disease still kills 1,700 Americans a day—and survival often depends on income, race, and access to care. But could artificial intelligence finally give humanity the upper hand?
On the latest episode of GZERO World, Ian Bremmer sits down with cancer researcher and bestselling author Siddhartha Mukherjee to explore how AI is changing the trajectory of modern medicine. From early detection and diagnostics to drug discovery and personalized treatment, Mukherjee believes we're entering a new era in the fight against cancer.
“The machine learns it, and it learns it forever,” Mukherjee says, describing how AI can now generate new chemical compounds that have never existed—potentially designing cancer drugs from scratch. “You don’t need to train a new generation of chemists. The machine will now learn it for eternity.”
Mukherjee explains how this generative power can unlock faster, cheaper breakthroughs across all stages of cancer treatment—from identifying new carcinogens like “forever chemicals” to tailoring therapies to a patient’s specific biology. For a disease that touches almost every family, these advances aren’t just technological—they’re deeply personal.

The global refugee population is at historic highs, driven by war in Ukraine, violence in Sudan, state collapse in Venezuela, Taliban rule in Afghanistan, and a worsening humanitarian disaster in Gaza. On GZERO World, David Miliband, president & CEO of the International Rescue Committee joins Ian Bremmer to discuss the refugee crisis, the rise of forcibly displaced people around the world, and the crumbling humanitarian aid system amid the cancellation of USAID. What happens when the poorest countries are left to solve the hardest problems? And who–if anyone–is stepping up to help?
Miliband says that in 20 countries in crisis, there are more than 275 million people in humanitarian need, people that depend on international aid and organizations like the IRC to survive. There have been some recent positive developments—hundreds of thousands of refugees returning to Syria after the fall of the Assad regime, the potential for progress in the Eastern DRC, new technologies improving aid delivery. Still, Miliband says the world is facing a humanitarian crisis of historic proportions and unless the international community steps up, tens of millions will suffer.
“We face a new abnormal. 10 years ago, there were 50 to 60 million internally displaced people and refugees. Now, there's 120 million,” Miliband says, “The scale of impunity, the loss of international engagement is epic.”

As part of a wide-ranging conversation on the GZERO World podcast, oncologist and Pulitzer prize-winning author Siddhartha Mukherjee walks Ian Bremmer through one of the most groundbreaking uses of AI in medicine today: generative drug discovery. It’s not just about speeding up research—it’s about creating entirely new molecules that no human has ever seen.
Using AI, researchers can now analyze the shape of a dysfunctional protein—like one found in a cancer or autoimmune cell—and generate chemical compounds that could bind to and modify its behavior. “This is true generative chemistry,” Mukherjee says. “Every time we do this in collaboration with a machine, the machine learns it, and it learns it forever.”
The process is like solving a puzzle with a million possible pieces. With each failure, the AI learns more, narrowing down candidates until it finds a match. It’s already produced new antibiotics with never-before-seen structures—and Mukherjee believes this is just the beginning of a medical revolution.

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.

Pakistan’s most important relationship may be its deep strategic partnership with China. The two countries have close security ties and economic alignment, especially when it comes to managing their mutual adversary India. On GZERO World, former Pakistani Foreign Minister Hina Khar gives her view on the China-Pakistan relationship, which she sees as a stabilizing force in Southeast Asia. Given so much geopolitical uncertainty right now, Khar explains, the world has just started noticing Pakistan and China’s strong ties. But the relationship goes back decades.
Khar says Pakistan doesn’t see the world in competing blocs, and believes there’s value in maintaining friendly relations with Western countries as well as its immediate neighbor, China. Beijing’s Belt and Road program has made significant investments in Pakistan, which has sped up Pakistan’s development and allowed it to strengthen economic partnerships with its neighbors. When multilateral institutions stopped financing infrastructure projects, China was able to provide goods and investment loans, helping to build trains and highways in Pakistan, as well as Iran, Afghanistan, and Uzbekistan.
“This is a country [the world sees] as very belligerent, very hegemonic. We’ve always seen in our region, an immediate neighbor to China, that it only relies on economic relationships,” Khar says, “Within Pakistan and the broader region, China has been a force of stability.”

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.”
