As global leaders gather for climate negotiations, it’s the world’s poorest who stand to lose the most. But here’s where it gets controversial: while wealthy nations debate emissions targets, millions in poverty are already facing the brutal consequences of a warming planet. Let’s take Luis Cassiano, a resident of Rio’s Arara neighborhood, as an example. When the summer heat hits, it doesn’t just linger—it bakes the red brick and concrete homes, turning them into ovens long after the sun sets. Cassiano, who’s lived there for over 30 years, admits he’s growing increasingly anxious as heatwaves become more frequent and intense. Even with the green roof he installed a decade ago—which cools his home by up to 15°C (27°F) compared to his neighbors—he still struggles to stay comfortable. His air conditioner, a luxury few in his community can afford, is unreliable due to frequent power outages from an overburdened grid. ‘The summer sun nowadays is terrifying,’ he says. And this is the part most people miss: Cassiano’s story isn’t unique. It’s a stark reminder that for 1.1 billion people living in acute poverty, climate change isn’t a distant threat—it’s a daily battle for survival.
As leaders convene in Brazil for these talks, the stakes couldn’t be higher. Poor communities like Arara are disproportionately vulnerable to extreme heat, superstorms, and other climate hazards, yet they have the fewest resources to adapt. But here’s the kicker: even if countries pledge to cut emissions, it’s the implementation of these plans—and the billions of dollars needed to fund them—that will determine whether people like Cassiano have a fighting chance. That’s why the choice of Belem, a relatively poor city on the edge of the Amazon, as the host location has been praised. ‘This is where climate meets poverty, meets demand, meets financing needs, and meets the reality of the majority of the world’s population,’ said Inger Andersen of the U.N. Environment Programme.
But here’s where it gets even more contentious: it’s not just the global south that suffers. A U.N. Development Programme report reveals that even in highly developed countries, 82% of people living in poverty are exposed to at least one of four climate hazards: extreme heat, drought, floods, or air pollution. Carter Brandon, a senior fellow at the World Resources Institute, explains why: ‘Climate change doesn’t just destroy buildings or bridges—it destroys livelihoods. And if you don’t have savings, that’s devastating.’
Take agriculture, for instance. While relatively developed countries may see farm yields drop significantly under different warming scenarios, poorer nations will be hit harder. Africa, home to over 500 million people in poverty, is particularly at risk, with many relying on crop yields for survival. Ismahane Elouafi of CGIAR believes technology could ease the pressure on farmers, but many can’t afford it. And this year’s COP? She’s not confident it will deliver the funding needed.
Here’s the bold question: Are we prioritizing emissions reductions over human suffering? Microsoft co-founder Bill Gates thinks so. He’s called for a shift in focus, arguing that ‘there’s no apocalyptic story for rich countries—the real challenge is in poor countries.’ But Pedro Conceição of the UNDP disagrees, stating that poverty reduction and climate action aren’t tradeoffs—they’re inseparable. ‘The idea that climate is a future problem needs to be thrown out,’ he says. ‘It’s already here, and it’s hitting the poorest the hardest.’
So, what do you think? Are global leaders doing enough to address the intersection of poverty and climate change? Or is the focus still too narrow? Let’s spark a conversation—because the lives of billions depend on the answers.
