After months of mutual animosity, President Donald Trump and New York City Mayor-elect Zohran Mamdani met for the first time in a widely anticipated meeting late last week. But after the two discussed Mamdani’s plans to lower the cost of living in New York City, where both men grew up, Trump said that he and Mamdani “agree on a lot more than I would have thought” and promised to work together once Mamdani takes office in January.

Nations are struggling to reach a final text agreement at the COP30 U.N. climate summit in Belém, Brazil. Decisions are made by consensus at COPs, requiring consent among 192 countries, and the biggest fight over the draft text is the exclusion of a roadmap to phase out fossil fuels. Reportedly Saudi Arabia, China, Russia and India are among those that rejected the roadmap. But more than 30 countries are saying they will not accept a final deal without one.

Thousands of Amazonian land defenders, both Indigenous peoples and their allies, have traveled to the COP30 U.N. climate conference in Belém, Brazil. On Friday night, an Indigenous-led march arrived at the perimeter of the COP’s “Blue Zone,” a secure area accessible only to those bearing official summit credentials. The group stormed security, kicking down a door before the United Nations police contained the protest.

As negotiations draw close to a conclusion at the COP30 U.N. climate summit, nations are still sharply divided over the future of fossil fuels. Delegates representing dozens of countries have rejected a draft agreement that does not include a roadmap to transition away from oil, coal and gas. Ralph Regenvanu, Vanuatu’s minister for climate change, says a number of nations refused to “entertain any mention of fossil fuels” in the outcome statement from COP30.

As we broadcast from the COP30 climate summit in Belém, Brazil, we are joined by one of Brazil’s most prominent scientists, Carlos Nobre, who says the Amazon now produces more carbon emissions than it removes from the atmosphere, moving closer to a “tipping point” after which it will be impossible to save the world’s largest rainforest. “We need urgently to get to zero deforestation in all Brazilian biomes, especially the Amazon,” he argues.

A new report titled “Data Crunch: How the AI Boom Threatens to Entrench Fossil Fuels and Compromise Climate Goals” from the Center for Biological Diversity warns the booming artificial intelligence industry’s high resource consumption threatens the world’s climate goals, despite rosy prognoses of AI’s projected benefits. Co-author Jean Su says that the increasing use of AI for military applications offsets any positives it offers for climate change mitigation.

In a wide-ranging conversation, Brazil’s first minister of Indigenous peoples, Sônia Guajajara, spoke with Democracy Now! at the COP30 climate summit in Belém. She addressed criticisms of the Lula government in Brazil, which has championed climate action even while boosting some oil and gas exploration in the country; celebrated the strong presence of Indigenous representatives at this year’s climate talks; and stressed the need to phase out fossil fuels.

As we broadcast from the COP30 climate summit in Belém, Brazil, calls are growing for stronger protections for refugees and migrants forcibly displaced by climate disasters. The United Nations estimates about 250 million people have been forced from their homes in the last decade due to deadly drought, storms, floods and extreme heat — mainly in the Global South, where many populations have also faced repeated displacement due to war and extreme poverty.

Sudanese climate diplomacy researcher Lina Yassin is supporting the Least Developed Countries Group at the U.N. climate summit in Belém, Brazil. The group is composed of 44 countries, including Sudan, whose cumulative emissions amount to less than 1% of total global emissions. “They are the countries that have the least amount of resources to respond to the climate crisis,” explains Yassin.

At the U.N. Climate Change Conference in Belém, Brazil, we sit down with Colombian environmentalist Susana Muhamad, who served as Colombia’s minister of environment and sustainable development from 2022 to 2025. Muhamad discusses the U.N.’s mandate to mitigate the acceleration of human-caused climate change and condemns the powerful, diverting influence of the fossil fuel lobby.

Congress has finally voted to compel the Justice Department to release the files on Jeffrey Epstein, the deceased convicted sex offender and power broker. After a near-unanimous vote in both legislative chambers, President Trump now says he will sign the bill into law. We play statements from a press conference held by survivors of Jeffrey Epstein’s abuse, who are celebrating the long-awaited win for transparency and accountability.

With negotiations in their second week here at the COP30 climate conference in Belém, Brazil, we get an update on the United Nations talks from Asad Rehman, chief executive of Friends of the Earth. He says COP30 is taking place against a backdrop of rising far-right authoritarianism, climate denial, and genocide in Gaza, which are all testing the “rules-based system” underpinning the U.N. climate framework.

As Democracy Now! broadcasts from the COP30 U.N. climate summit, we speak with Kumi Naidoo, the longtime South African human rights and environmental justice activist who is president of the Fossil Fuel Non-Proliferation Treaty Initiative. He discusses U.S. absence from climate talks, Gaza, and wealthy countries refusing to take accountability for the climate crisis. “We’re not asking the rich nations for a charity here. We are asking them to pay their climate debt.

We speak with one of the Indigenous leaders at the U.N. climate summit in Belém for the climate negotiations, in greater numbers than ever before, taking center stage at COP30. They are calling “to end the persecution of our land defenders,” says Diana Chávez, member of the Pastaza Kichwa Nation, with Pakkiru, an Indigenous organization based in Ecuador’s Amazon. “We’re fighting to keep our territories.

As we broadcast from the United Nations climate summit in Belém, we look at Brazil’s contradictory climate policies. The Lula government has reduced deforestation in the Amazon while also approving oil drilling near the Amazon. “Many parts of the Amazon are now reaching a tipping point, so a point of no return,” says Ilan Zugman, Brazilian climate activist and 350.org’s regional head for Latin America and the Caribbean.

Mayor-elect Zohran Mamdani is less than two months away from taking office in New York City. Mamdani’s history-making campaign, grounded in community organizing, propelled the little-known Assembly-member to victory. Candidate Mamdani famously began the campaign polling at just 1% and overcame the intense scrutiny, Islamaphobic attacks, criticism for his support for Palestinian rights, and more.

Democracy Now! is broadcasting from the U.N. climate summit in the Brazilian rainforest city of Belém, near the mouth of the Amazon River, where the COP30 summit has entered its second week of negotiations. The gathering comes 33 years after the Rio Earth Summit, which created the U.N. Framework Convention on Climate Change.

To kick off our week of coverage from the COP30 climate summit in Brazil, we play video of a major protest that took place Saturday, when tens of thousands of people took to the streets of the host city Belém to demand urgent climate action. The Indigenous-led action was the first major climate protest at a United Nations climate conference since 2021; protests were banned by Egypt, the United Arab Emirates and Azerbaijan, the three previous host countries.
