Fires depend on: ♨️ Weather ⚡ Ignition 🍂 Fuel 🧯 Suppression In North America: ♨️ Climate change = hotter and drier ⚡Ignition = no real change 🍂 Fire deficit = more fuel 🧯Warmer nights = suppression is hard What should we do? 📉 Cut emissions ✅ 🔥 Controlled burns ✅ 🍁 Rake more? ❌ 🇨🇦 Be mean to Canada ❌

Experts say the world is experiencing two opposing fire trends because of human impact.

El Nino thread! 🌊 My Key Takeaways: 1. This event is well on its way to being a very strong event rarely seen in the last 75 years. 2. Right now, it's most likely not the strongest on record. 3. The warming of the nino3.4 region due to climate change does not add to El Nino strength!

Beach holidays in the climate crisis, France. As an old viral quote said: “Climate change will manifest as a series of disasters viewed through phones with footage that gets closer and closer to where you live until you’re the one filming it.”

James Doohan wasn’t just Montgomery "Scotty" Scott, he wasa Canadian who served his country and landed on the beaches of Normandy on D-Day. Then he turned to acting, was trained by Lorne Greene and even helped develop the Klingon language. This is his story. 📸 NBC 🧵 1/12

James Doohan as Scotty sits at a control console aboard the USS Enterprise, wearing a red Starfleet uniform with a black collar and a delta insignia on his chest. He leans slightly forward with one hand resting on the console, his dark hair neatly combed to the side. Behind him are colorful control panels and futuristic set walls characteristic of the original Star Trek series bridge.

I had a reporter ask me if there was any connection between the fires in Canada and the flooding in Texas. I said: of course there is a connection. The connection is increasing temperatures.

Probably more helpful to think of them not so much as “Canadian wildfires” but rather “climate change wildfires currently consuming Canada”

As wildfire smoke blankets tens of millions of Americans, schools need a rethink of how they plan for and react to wildfire smoke events. Jessica Yu on our team spent two years deploying monitors in school classrooms to measure smoke intrusion into individual rooms.

Our 2026 fire season was quiet, and just like the rapid transition from winter to summer (bypassing spring) in much Canada, our fire season went from quiet to crazy full on. Rapid increase in area burned (and smoke) from fires in the NWT and QC and more recently ON. See hot spot graph below

Meta now lets anyone use your Instagram photos in AI images without your consent. SAG-AFTRA recommends that #SagAftraMembers (and all Instagram users) opt-OUT of Meta’s new AI image generation tool, Muse Image. Take action to protect your likeness.

If you want to avoid AI generations of your Instagram posts without switching your account to private, you’ll have to dig into the app’s settings. Open the Instagram app, tap your profile, and then tap the three lines in the top-right corner of the screen. Then, scroll down to the Sharing and reuse tab. Here is where you should see a section labeled Allow people to use your content on Instagram and with AI features on Meta, with a toggle for Posts and one for Reels.

Currently 85 miles of river drying on New Mexico's Middle Rio Grande. a) That's a lot. b) We literally pay people to go out and look at the river every quarter of a mile (? I think this is the right spacing. ?) to see if the river is dry. What a weird job.

I'm saddened by the news that Rex Adams has passed. Rex was always so unfailingly positive and generous and had an outsized influence on generations of tree-ring scientists. I will always be grateful for him treating my mom like a VIP when she visited me at LTRR. A "fun guy", always and forever.
