As World Convenes in Brazil, WHO Warns of Dire Health Impacts of Climate Crisis
"The climate crisis is a health crisis—not in the distant future, but here and now."
Nov 14, 2025
The World Health Organization on Friday issued a report documenting what it described as a "global health emergency" being caused by the climate crisis.
The report, which was released jointly by the WHO, the government of Brazil, and the Brazilian Ministry of Health at the start of the United Nations climate summit (COP30) being held in Belém, Brazil, warns that global healthcare infrastructure is not currently sufficient to deal with the climate emergency, and that "1 in 12 hospitals could face climate-related shutdowns" worldwide.
Overall, the report finds that hospitals are experiencing "41% higher risk of damage from extreme weather-related impact compared to 1990," and that the number of at-risk health facilities could double if the global temperature continues rising at its current pace.
Ethel Maciel, COP30’s special envoy for health, said that flooding that decimated the southern Brazilian state of Rio Grande do Sul last year showed the importance taking the climate crisis seriously, especially since the floods also led to "the largest dengue epidemic in history, driven by these climate changes."
"So, it is not something for us to think about in the future; it’s happening now," Maciel added. "So, thinking about how to adapt our system is urgent.”
Professor Nick Watts, director of the NUS Centre for Sustainable Medicine, recommended dedicating 7% of current climate adaptation finance toward making healthcare infrastructure more resilient to climate change, which he said would "safeguard billions of people and keep essential services operating during climate shocks—when our patients most need them."
WHO Director-General Tedros Adhanom Ghebreyesus said that the report should give nations urgency to decarbonize as quickly as possible.
"The climate crisis is a health crisis—not in the distant future, but here and now," he said. "This special report provides evidence on the impact of climate change on individuals and health systems, and real-world examples of what countries can do—and are doing—to protect health and strengthen health systems."
An Urgent Message From Our Co-Founder
Dear Common Dreams reader, It’s been nearly 30 years since I co-founded Common Dreams with my late wife, Lina Newhouser. We had the radical notion that journalism should serve the public good, not corporate profits. It was clear to us from the outset what it would take to build such a project. No paid advertisements. No corporate sponsors. No millionaire publisher telling us what to think or do. Many people said we wouldn't last a year, but we proved those doubters wrong. Together with a tremendous team of journalists and dedicated staff, we built an independent media outlet free from the constraints of profits and corporate control. Our mission has always been simple: To inform. To inspire. To ignite change for the common good. Building Common Dreams was not easy. Our survival was never guaranteed. When you take on the most powerful forces—Wall Street greed, fossil fuel industry destruction, Big Tech lobbyists, and uber-rich oligarchs who have spent billions upon billions rigging the economy and democracy in their favor—the only bulwark you have is supporters who believe in your work. But here’s the urgent message from me today. It's never been this bad out there. And it's never been this hard to keep us going. At the very moment Common Dreams is most needed, the threats we face are intensifying. We need your support now more than ever. We don't accept corporate advertising and never will. We don't have a paywall because we don't think people should be blocked from critical news based on their ability to pay. Everything we do is funded by the donations of readers like you. When everyone does the little they can afford, we are strong. But if that support retreats or dries up, so do we. Will you donate now to make sure Common Dreams not only survives but thrives? —Craig Brown, Co-founder |
