Amazing chart! Daily anthropogenic global CO2 emissions (MtCO2 per day). 2023, 2024 and 2025 (up to Sep 30).
Weekly peaks seem to fall on Thursday-Friday;
Weekly troughs seem to fall on Sundays.
Makes sense that Annual peaks occur during NH winter.

For those trying to keep up with what's what in this latest MOU between the Feds and Alberta, I've got you covered:
We're still light on the details, as the announcement will be formally made tomorrow. But gleaning from news reports, this is the deal:

Who else remembers *checks notes* 6 months ago when climate misinformers were telling us that Antarctica was gaining ice? 🙋🏻♂️

@jessebrown.bsky.social There’s probably an interesting story to be told here (all Canadian media X accounts seem to be based in the US - or at least VPN’d through there… why?)

This is one of the coolest freakin' science stories I've ever heard of! Members of the Haíɫzaqv First Nation of BC noticed some animal had been damaging their *underwater* crab traps, so they set up a camera. This is what they found! www.science.org/content/arti...
Have wild wolves learned to use tools?
Video captures a lone female pulling crab traps out of the water, but does it count as tool use?

@kevinroose.com @caseynewton.bsky.social Interesting bit on space data centres but y’all barely mentioned one of the main benefits - they are cooled by the vacuum of space, so don’t need to draw on freshwater sources on Earth.

I've just spent way too long trying to reconcile this chart from Bloomberg (first image) about Carbon Sinks (in an article by @eroston.bsky.social) with the latest GCP report (2nd image; lead author @pfriedling.bsky.social) and CT's analysis of GCP data (third image). I can't. Something's way off🤷♂️

Climate skeptics who have been awful loud about how Arctic Sea Ice extent levels are 'stabilizing' over the last decade sure are quiet about the Land Sink over this same time period.

Seeing so much misinformation out there related to solar geomagnetic storms... Seemed like a good opportunity to write about another common bit of misinformation - the myth that modern global warming is being caused by the sun (TL;DR it's NOT the sun, it's us). Link in next post...

Impossible to pick just one picture from tonight’s northern lights show, but this one stood out as it got so bright that the snow was glowing pink🤩
