⛪️ Good news: In the U.K., over 100 church leaders are calling out climate misinformation, making the moral case for why it causes real harm and delays action. 🐍 Not so good news: Climate change is shifting where species live—and in the case of venomous snakes, a new global study finds rising temperatures could increase the likelihood of dangerous encounters for millions. 🌱 What you can do: In the Netherlands, nearly 13M pavement tiles have been replaced with plants through a nationwide “ti...
What if one of the most powerful climate solutions isn’t technology—but conversation? 💇♀️ Good news: Hairdressers may be some of the most effective climate communicators we’ve been overlooking. A U.K. study shows that when salons spark climate conversations, nearly 73% of clients say they’d adopt more eco-friendly habits. ⚠️ Not so good news: War doesn’t only devastate lives - it also drives massive emissions. A Climate and Community Institute analysis shows the first two weeks of the Iran...
🌱 Good news: Cities like London, Paris, and Barcelona are redesigning streets for people instead of cars. This cuts pollution while improving health, local economies, and quality of life. 🌡️ Not so good news: Rising nighttime temperatures are disrupting sleep worldwide, with cascading effects on health, learning, and productivity—especially for the most vulnerable. 🏡 What you can do: Simple steps like adding window film, choosing reflective roofing, and planting trees can keep your home coo...

Hope isn’t something we wait for: it's something we create. This week's Talking Climate news illustrates why it matters so much, and how innovation and courage can help! 💧 Good news: A solar-powered system can pull drinking water directly from the air—up to 1,000 liters of clean water a day, even in dry areas where billions of people already face water scarcity. 🧠 Not-so-good news: Climate change is increasingly affecting people's mental health, from Madagascar to Appalachia. In the U...
🌫️ Good news: London’s Ultra Low Emissions Zone cut pollution in half and brought the city into legal air quality compliance 184 years earlier than forecast, proving that climate policy is health policy. ❄️ Not so good news: While average snowfall is declining in many places, a warmer atmosphere holds more moisture: which can mean heavier snow and more dangerous winter extremes where temps stay below freezing. Climate change isn’t eliminating winter; in some places, it’s intensifying it. 🤝 ...
Most weeks, bad climate news feels like a deluge. But even in the midst of the storm, there's always good news too. Hang on to your seats, here we go! ✅ Good news: New Carbon Brief analysis finds China’s emissions have flattened and may even be starting to decline. Combined with their previous analysis showing China's clean energy exports cut global emissions 1% in 2024, and you can see there's reason for hope. ⚠️ Not-so-good news: The U.S. EPA has rescinded the Endangerment Finding, the sc...
What do the Winter Olympics, Bad Bunny, and “Grey’s Anatomy” have in common? This week I’m delighted to welcome climate columnist Sammy Roth as guest editor of Talking Climate. He's spent over a decade writing on climate, culture, and clean energy, and his stories always inspire and surprise! 🌟 Good news: Climate storytelling is finally breaking into mainstream culture, thanks to Winter Olympians, Hollywood story-lines and Super Bowl halftime shows. 📉 Not-so-good news: Climate still ...
🏂 Good news: Winter athletes are becoming powerful climate advocates because they’re seeing the changes firsthand. From Olympians to fans, groups like Protect Our Winters are pushing sports organizations and policymakers to cut emissions and protect the winters their sports depend on. ⛷️ Not-so-good news: Climate change is rapidly whittling down locations where Winter Olympics can reliably be held. By mid-century, only a handful of locations may be cold enough—and most would rely on artifici...
🐘 Good News: What if wildlife isn’t just impacted by climate change, but part of the solution? From forest elephants and sea otters to whales, penguins, and beavers, animals help store carbon, cool the planet, and keep ecosystems functioning. Protecting biodiversity isn’t separate from climate action: it’s central to it. 🐧 Not-So-Good News: Climate change is exacerbating the biodiversity crisis: skewing sex ratios in reptiles, shifting breeding seasons for penguins, and unraveling food webs ...
This week’s Talking Climate is a mega-edition, a deep dive into the hot and contentious topic of AI and climate. 💚 Good news: AI and machine learning are already helping scientists process vast amounts of data, improve climate and energy modeling, protect wildlife, detect wildfires, and more.

This has been an extraordinarily hard year for science both globally, and especially in the United States. In this week’s Talking Climate, I unpack why recent cuts to scientific programs and data don’t only affect climate research in the U.S. They weaken the knowledge infrastructure we rely on to protect public health, manage risk, and make good decisions around the world. I also share good news from Sweden, where smart policy has turned waste into heat and power, reminding us that the mos...
