Happy New Year to my Bluesky friends! A couple mornings ago I was fortunate enough to find myself atop of Smith Rock State Park near Bend, Oregon. I arrived to a dense fog inversion and climbed above the fog just in time for sunrise!

Pulling climate data offline, canceling research grants, and de-funding scientific institutions doesn't just suppress climate information. It weakens the foundation we rely on to make good decisions of any kind. In my latest "Tea with Katharine" I share why investment in science is so important!

Every sunset is magical. Tonight’s was even more dazzling than usual

Merry Christmas to all who celebrate! We had an amazing morning with an ever-changing sunrise and a 7-7 tie vote at the bagel shop for the favorite, so I got to be the tiebreaker today. Tap for full size. I hope you have a great day!

A little message from me that might help anybody who finds this time of year a little tough. niallharbison.substack.com/p/to-those-w...

This was my first aurora capture of 2025, early morning on Jan 1. I'm wondering how many auroras I have left this year. Tonight's a possibility to add another.

#MEDIA🚨 Big Oil’s playbook revealed! Our new illustrated backgrounder exposes the 10 tactics the fossil fuel industry uses to delay climate action and keep Canada hooked on oil and gas 🌍🔥Check it out here environmentaldefence.ca/report/drawn...

Happy Wednesday! We are halfway through the week! The temperatures are rising so this will be the last day of the beautiful white snow covered beach; and with the sun is rising so far south we were able to get it all together. Tap for full size. I hope you have a great day!

Climate action is happening all around us — in communities, classrooms, churches, and unexpected corners of the world. Here are a few stories of hope, concern, and practical choices we can make together.

New tunes from yours truly. Strap in for the ride and if you have issues with SoundCloud DM me I can hook you up Listen to Praktik Swayze - Pulsation Cycle I by Praktik Swayze on #SoundCloud on.soundcloud.com/UinHhQ9GariR...

As I say here, this is not about saving the planet. The planet will be orbiting the sun long after we’re gone. The question is, will there be a healthy, thriving human society on that planet? The answer to that question is very much up for grabs at this point.

a big new one from me: I profiled a group of neighbors in west texas who have become the face of the abandoned well problem in the heart of oil country for @motherjones.com - an unlikely group of former industry workers and ranchers who are fed up with how Big Oil won’t clean up its messes:

TIL about a memorial ceremony in Iceland in 2019 to mark the end of a glacier, changing the place name from Okjökull to Ok (jökull = glacier). Uncompromising wording on the bronze plaque: "This is to acknowledge that we know what is happening and what needs to be done. Only you know if we did it".

This is U N B E L I E V A B L E. #Kilauea

This "conservative" govt's plans are NOT FOR THE PEOPLE but to conserve profits for private corps. Privatizing our water will be terrible, and Ford will cost you more at the tap. Harris made terrible decisions too with water, and cost many Ontarians their lives. And selling our beaches? Ford sucks!

🚨 Well the data is back, and as I figured, the news isn't good... #Arctic sea ice volume is currently the *lowest* on record for this time of year. Graphic from zacklabe.com/arctic-sea-i...

“We can’t all be expected to bike.” Fair. But that’s not the point. “Not everyone can or wants to bike. But some people can & do—and they deserve a safe, efficient, affordable way to move through the city. It’s about freedom of choice.” This & other useful comebacks, in @momentummag.bsky.social.

This is the future they're trying to take from you, people!!! yes, this is actual art done for SERI in the 1970s. We used to be a proper country, etc etc

“It remains the case that we are embarking on—in fact, accelerating—the biggest chemistry experiment on the planet in 66 million years, and one of the fastest derangements of the carbon cycle in the age of animal life.” www.theatlantic.com/science/2025...

Russia writing US policy. For discussion of the implications of this please listen to my conversation with Michael Weiss on Thinking Live: snyder.substack.com/p/oligarchs-...

If you haven't listened to this yet, I highly recommend it. All your basic questions about indoor air quality -- what are the pollutants? what tech can keep them out? what policies do we need? -- are answered.

Today on Volts: the subset of cleantech known as "electrotech" -- solar, batteries, heat pumps, etc. -- is marching toward inevitable victory, not because it's low-emissions (though it is), but because it's more efficient & cheaper. I discuss the good news with @kingsmillbond.bsky.social.

"The chemtrail theory is ultimately prideful. It’s a way for theorists to feel powerful + smart when they face things beyond their comprehension and control." People cling to ridiculous theories to meet their emotional needs - great explanation by @dratropos.bsky.social for @theconversation.com

Nearly every panel I spoke on this year ended with the same question: "What gives you hope?" My friends, that question expired years ago. (If you need receipts, my book Saving Us is literally a 300-page answer.) The real question is: How are you PRACTICING hope? Because Greta is right ..

🗞️Yesterday, two CCL members had letters published in the Globe and Mail on the importance and urgency of reducing our greenhouse gas emissions, with our without an emissions cap for the oil and gas sector. Check out the letters here:

Misinformation *is* central to democratic problems today, but the solution is *not* to correct such epistemic failures directly. Instead, we must address them at their roots, in social identity. Or so I argue in a new post for @apaphilosophy.bsky.social. blog.apaonline.org/2025/11/12/t...

Canada needs to do better! ✅Hydroelectric in the North to replace diesel use is very good. ❌New Fossil natural gas is very bad. We need climate action now for Canada's Major Projects!

I am on my way home to Toronto and the aurorae are absolutely phenomenal. If you are anywhere in the northern half of the continent, get outside and look up! Or better still, put your camera on a 10 second exposure and point it up.

Another challenging Tuesday

There's nothing inherently wrong with climate change. It's just that the ecosystems and built environments that we depend on as life support systems aren't equipped to handle the rapid changes. So if we want to live, we should deal with climate change ASAP.

Today is the 60th(!) anniversary of the first public report on the dangers of fossil fuel pollution. What happened? A whole lot of fossil fuel bullsh*t and corruption in service of a whole lot of nothing. All while pollution and warming escalated far beyond what scientist predicted in 1965.

Ontario’s Climate Accountability on the Chopping Block THIS HAS HUGE IMPLICATIONS Ontario cannot deliver real results without a clear plan. Targets without follow-through are empty promises, and chasing results without a plan is like driving blind. canada.citizensclimatelobby.org/media-releas...

As COP30 begins, here's a gentle reminder that well-intentioned half measures aren't going to solve the climate crisis. The era of fossil fuels must come to an end. My latest in The Guardian... www.theguardian.com/commentisfre...

Australia has so much electricity from solar power that it is going to start offering free electricity to everyone for at least three hours during the day as the wholesale price of power goes negative electrek.co/2025/11/04/a...

Happy Wednesday! I have been so scattered that I never even shared this morning’s sunrise which as you see here was a real stunner five minutes before the sun broke the horizon. Tap for full size. I hope you have a great day!

I've finally got around to curating a selection of films about the #climate crisis 🎥 There's lot of mediocre climate films out there, but for me these stand out head & shoulders above the rest 🎞️ They make excellent resources for classrooms, lecture halls, or community cinema's 🎬 Thread:🧵Plz RT

Happy Halloween! Just moments after today’s sunrise, I began a string of engagements that have only now ended, 13 hours later, so I apologize that this is late! After a tepid start you’ll see we ended up with a real beauty. Tap for full size. I hope you have had a great day!

“Here’s the thing, Bill Gates: There’s no ‘patch’ for the climate crisis. And there is no way to reboot the planet if you crash it. The only safe and reliable way out when you find yourself in a climate hole is to stop digging—and burning—fossil fuels.” — @michaelemann.bsky.social

Have you noticed plane turbulence is getting worse? It’s not your imagination. It’s climate change.

Free From ICE!

Comedian and musician Robby Roadsteamer was detained by ICE in Portland earlier today, sparking outrage and alarm. Roadsteamer was grabbed as he sang a parody of Rod Steward's "Da Ya Think I'm Sexy" in front of an ICE Center in Portland before being grabbed by agents and carried into the facility.

Record-breaking 2024 Amazon fires drove unprecedented carbon emissions and ecosystem degradation - The fires released 791 million tons of CO2, roughly equivalent to the annual emissions of Germany #climatecrisis www.egu.eu/news/1509/re...

This image shows a stack of six lightning bolts nearly striking the same spot six time in only one minute of elapsed time! Mother nature really had it out for whoever was down there... #photography

We can do it here too! Cleaner air and less carbon for better health!

Each year in the United States, pollution from the oil & gas industry causes 91K premature deaths, more than 10K pre-term births, 216K cases of childhood asthma, & more than 1600 cancer cases. People of color are significantly more affected, with the biggest burden in predominantly Black communities

The global whaling industry experienced a boom c. 1840-1950 as technology allowed whalers to hunt the Southern Ocean around Antarctica. Under standard models, we would have expected krill populations to have *exploded*. Instead, they DROPPED exponentially. Let's talk about the KRILL PARADOX.
