Is the climate movement getting in our own way? 👀 Sometimes, we're so busy picking apart how our allies talk about climate change that we lose sight of what we're all trying to accomplish. Adam Met from AJR and Planet Reimagined and I talk about climate hushing, why we can't let perfect be the enemy of good, and how we can spend less time fighting each other and more time moving solutions forward. Because we have enough obstacles to overcome without becoming obstacles for each other.

"When we stop talking about climate change like it's a political issue and start talking about it as a shared challenge that we all need to work together to solve, that's when we'll finally be able to start talking about saving ourselves," write Katharine Hayhoe and Dana Fisher time.com/article/2026/09/21/…

A flood doesn’t ask who you voted for before it sweeps your house away. Wildfire smoke doesn’t check your political affiliation before it chokes the air. So why do we keep talking about climate change as if it belongs to one side? In our new TIME op-ed, Dr. Dana R. Fisher — who led the research behind the Talking Climate Collaborative’s new Landscape Assessment — and I look at what climate communicators across the U.S. and Canada can teach us about connecting climate change to the things people already care about most. The bottom line is this: Climate impacts are not partisan. And caring about our homes, health, families, and futures shouldn’t be either. Read more: time.com/article/2026/09/21/…

If we want better climate conversations, we need to invest in the people having them. I know firsthand how isolating this work can be — and how much more effective we could be with better access to one another, to evidence about what works, and to the support needed to keep going. That’s why I’m so excited to finally introduce the Talking Climate Collaborative. This week, my friend, fellow co-founder, and TCC Executive Director @bernwoodsplacky is joining me to share why we built TCC and what our new Landscape Assessment taught us about the field. 📣 Good news: People already care, and climate communicators are working hard to break the silence. Nearly 8 in 10 communicators we surveyed talk about climate at least weekly. 🤐 Not-so-good news: A third surveyed work entirely alone, and only 41% have received funding for climate communication in the past five years. Many also want more help finding collaborators and learning what works. 🗣️ What you can do: Explore TCC’s new tools, resources, network, and Landscape Assessment — and find something that can help you start your next climate conversation. Communication is climate action. The more we talk, the easier it becomes for others to join in. Read on: talkingclimate.ca/p/communic…

This week, I handed Talking Climate over to climate policy expert @leahstokes. She says, talking about climate change doesn't lose elections - it wins them. And, check out her Carbon Wave Calculator. As Leah says, a footprint is what one person leaves behind. A wave is what we make together 💚 talkingclimate.ca/p/leahstok…

This week I handed the newsletter over to climate policy & politics expert Leah Stokes. She says, talking about climate change doesn't lose elections. It wins them. Read on! 🗳️ Good news: Research shows U.S. candidates who make climate a top priority get a 4.5-point bump in support, and voters don't want it traded off against affordability or healthcare. 🏫 Not-so-good news: California just let its $200 million program to put heat pumps and air conditioning in schools lapse, in the same week that extreme heat forced half a million CA schoolkids into shortened or online school days. 🌊 What you can do: Try Leah's new Carbon Wave Calculator. It shows how your own choices at home (a heat pump, an EV, an e-bike) can build a wave that ripples out to your city, your state, and even national policy. As Leah says, a footprint is what one person leaves behind. A wave is what we make together 💚 talkingclimate.ca/p/leahstok…

As heat waves scorched Europe and North America this summer, nuclear and fossil fuel plants closed down ... but solar and batteries kept the lights on. -Good news: Solar delivered a full 25% of the EU's electricity in June and July, and batteries stored it to power the grid overnight. -Not-so-good news: Nearly half of all children under ten now endure at least 20 days a year of dangerous, climate-driven heat. -What you can do: A new Play It Cool program from The Aspen Institute, led by my friend and Talking Climate Collaborative founding teammate Laura Schifter, aims to protect young athletes from heat illness with three steps: Speak Up, Sit Out, Cool Down! This week, memorize these three steps and share them with a parent, coach, or young athlete you know. Knowing what to do can save a life! talkingclimate.ca/p/powering…

Hi 👋 I'm a climate scientist and notorious troll blocker. And whenever extreme heat hits, the same comments show up: “It’s just summer.” “It’s been hotter before.” “Just tough it out.” In this episode of Cold Facts, Hot Takes, I take on the myths and explain what the science actually says about today’s heat waves. Enjoy the preview: talkingclimate.ca/p/preview-… Upgrade to watch the full episode: talkingclimate.ca/p/cfht-hea…

Are the recent extreme weather events due to climate change, or a super El Niño? Chief Scientist at @nature_org @KHayhoe explains how climate change is “loading the weather dice against us.” Link to full conversation: open.spotify.com/episode/0l9…

Bad climate news finds us everywhere: our inboxes, our screens, and more ... but good news is often hiding in plain sight and sometimes it's right on the roof of your own old high school. 🏫 Good news: My dad just tipped me off that the Toronto District School Board now has 358 buildings with rooftop solar; that's nearly 150,000 panels quietly generating clean power over students' heads as they study. 🏔️ Not-so-good news: A catastrophic flash flood in the Himalayas has killed more than 1,000 people and left thousands more missing across Nepal and China. It's a disaster climate change made more likely and one that fell hardest on those who did the least to cause it. 🙏 If you'd like to help, please donate to Nepal's national Disaster Relief Fund: pmdrf.nchl.com.np/ 🔦 What you can do: Go climate sleuthing where you live: look for the solar panels, electric buses, bike lanes, and heat pumps already showing up around you. Then, share what you see with others around you. The more visible these solutions get, the faster your neighbour asks, "why not here?" 💚 talkingclimate.ca/p/a-climat…

The heat keeps setting records & the hard news keeps coming ... but hopeful climate stories are hiding in ordinary places: a kitchen, an elementary classroom, and a retired coal plant. Read on! 🍳 Good news: A new study found that when families asthma swapped their gas stove for an electric one, hospital visits and missed work & school days dropped by 70%! 🌡️ Not-so-good news: A new study measuring heat the way our bodies actually feel it, factoring in humidity and wind, found that a billion more people now endure extreme heat stress each year than in the 1970s. 📚 What you can do: The Cooler Communities program has put 300,000 free children's books into elementary classrooms, teaching them where their energy comes from and the power they have to shape their future This week, share one of these stories with someone who needs a reason for hope. You don't have to wait for permission to start making a difference 💚 talkingclimate.ca/p/asthma-i…

Last week's must-read: Want to do something about climate change? Talk about it alaskabeacon.com/2026/08/19/… When we read the title of this piece, we knew it had to be about our favorite climate scientist, @KHayhoe, who consistently says the best thing to do to effect change is to talk. “Talking catalyzes action. If we want to catalyze action in any sector, whether it’s in electricity, transportation, food, resilience or anything, talking is the first step” toward connecting the head and the heart. “For years, I’ve been asking people: Do you feel like the weather is getting weirder? I haven’t had a single person tell me they didn’t think so,” she says. “Most people have tons of stories to tell me. Then I just help them connect the dots. I say, ‘That’s exactly what’s happening here, and it’s happening all over the U.S. and all around the world. This is the number-one way that climate change is affecting us.’ Then we’ve closed the head-to-heart gap, just like that — and they did it themselves.” Resist climate hushing and embrace climate talking! And if you haven’t read it yet, Katharine’s book Saving Us is a great read!

Fact-checking the anonymous trolls, Part 4. 200 years of science agrees -- climate is changing, humans are responsible, the impacts are serious but there are solutions, if we act now.

Fact-checking trolls, Part 3. Every dataset on the planet - including thermometers, buoys, satellites, phenological data, the peach tree in your back yard, and more - shows the planet is warming. See responses to arguments 6 and 7 here: skepticalscience.com/argumen…

I've heard thousands of climate denial arguments over the last few decades. But do you know they all fall into one of 5 categories? 1. Climate isn't changing 2. Humans aren't responsible 3. The impacts aren't bad 4. We can't fix it 5. It's fake Too often we get encouraged when someone goes from category 1 to 2; or 2 to 3; or even 3 to 4. At least they admit it's real and human-caused, we think! But I don't get encouraged. Because I know that every type of argument above has the same goal: to delay climate action as long as possible. The only way forward is to abandon this list entirely. If someone brings up an argument, answer it briefly then pivot immediately to how climate solutions will give us a better future, and we all want that. piped.video/watch?v=nkMIjbDt…
