What *actually* works — right here, right now — to address climate change? Here you go. This is the result of thousands of hours of painstaking research and analysis from the Project Drawdown team.

So everyone knows that northern cod collapsed completely in the 1980s and never recovered. Well... it's actually kind of recovering now. Spawning biomass is at pretty good levels, while catches remain at a tiny fraction of the heyday levels. publications.gc.ca/collections/...

NOAA proposed budgets would eliminate science and management of marine mammals and sea turtles, firing 311 scientists and cutting the budget by more than $100m. Also a long list of program terminations... See pages 16-20 www.commerce.gov/sites/defaul...

🚨I promised I'd say more on the Royal Society and Elon Musk, so here it is. 🚨 I've resigned my position as Associate Editor at Royal Society's journal Open Science in protest at their lack of action over Elon Musk. My op-ed in @theguardian.com www.theguardian.com/commentisfre...

Elon Musk is a proven danger to good science, but the Royal Society won’t say so. That’s why I resigned | Kit Yates
It is vital to act, and I urge colleagues to do so. How can we stand by and laud this man while he undermines scientific integrity? asks academic and author Kit Yates

Trudeau: "I want to speak first directly to the American people. We don't want this. We want to work with you as a friend and ally. We don't want to see you hurt either. But your government has chosen to do this to you. As of this morning, markets are down and inflation is set to rise dramatically."

At our research site we used STARLINK for data transmission. We’ve decided to cancel and move to cellular. Not worth the uncertainty it may get cut off without notice and the fascism free service will also be nice!!

In what world does Pierre Poilievre believe it's okay for him to not receive a security clearance while running to become Prime Minister?
News Graphic that reads: "Poilievre rejects terms of CSIS Foreign interference briefing. Spy agency said in December it would give Conservative leader briefing without him needing security clearance."

"Masculine Energy"
Panel 1: Mark Zuckerberg stands on the stage at a Meta all-hands meeting, wearing a little chain and a shirt that says "Cool Dude." "I think our company could use more Masculine Energy," he says into a mic. In the crowd, an employee raises their hand. "Excuse me, Mr. Zuckerberg," the person asks. Panel 2: The person stands up, asking, "By "Masculine Energy," do you mean a mature definition where men in power use their relative strength to protect and uplift those less privileged?" Panel 3: The person continues, "…or a more childish definition where men in power are free to be aggressive and harm others without being held accountable?" Panel 4: Zuck stands silent for a beat. Panel 5: "You're all fired," he says.

Let’s see how well this Bluesky app works for fish modelling. I want to make a dead recapture CJS model with release location and release size and year as co-variates. Anyone have a useful reference / code they can share?
