This is a #geoscience question for Bluesky. What is the largest cliff or bluff on Earth that is composed entirely of chert? The late Guy Edwards and I used to joke about what the climbing on such a cliff would be like. But chert rarely if ever seems to form big enough cliffs to climb on.

Being a geographer, every time I see the story framed this way I get a bit "well actually". Africa has mostly been shown "at its actual size" all along! The problem is that everything else has been systematically distorted to be too big!

A US-linked network of fake websites is promoting Alberta separatism to AI chatbots
The websites present crude, AI-generated slop disguised as the voice of real Albertans. But they're made in Florida — and they're not even targeting Albertans directly.

everyone is going insane for this but it's a slop machine. the first character i rolled was a child who died in 5th century BCE Iran and the site generated me a picture of "his home" which had drainpipes and telephone wires. fuck this.

We're dug into the seismo-acoustic data but it was inconclusive - our ground-based network is growing though so we'll be in a better position for the next one. Also looking into InSAR and optical (but cloudy), so maybe we'll have something more concrete in a few more days.

This kind of report should be accompanied by a press conference—not with some low-level bureaucrat, but with the prime minister. Flanked by all of his ministers. In prime time, with technical briefings. This report says we're facing unimaginable disaster, yet we didn't even get a briefing.
Environmental groups say there’s a reason why the federal government quietly released its latest climate report, which finds that average temperatures in Canada are set to go up by at least 3.5 C by the end of the century.

BC politics is fascinating because it shows the discrepancy between voting and parties. No one votes for parties, they vote for individuals. But it's parties and not individuals that get all the collective action: memberships, bureaucracies, administrators, leadership contests, donations etc.
Not to mention that basically all marine CDR proposals are fuckin grift anyways. Creating anoxic oceans is a VERY BAD IDEA.
They say Canada is not a science superpower but the 2026 Ig Nobel prize numbers DO NOT LIE ?!
