Today in self-owns by the modern Know-Nothings

Since I first heard the term ‘ #prebunk’ it has irked me to no end. It’s a complete oxymoron for the intended usage. (It translates to putting bunk in ahead of time.) The correct terms just occurred to me: #bunkproof or bunkproofing. Used like waterproofing.

Sunday 11/2 at 10am PT on Climate Chat: "Climate Politics When It's Too Late" with @wimcarton.bsky.social. Is adaptation, CDR & SRM just scams to keep FF emissions going? What needs to change? @leonsimons.bsky.social @bikingmzstacey.bsky.social @radsci.bsky.social youtube.com/live/oxtkKTd...

Heartbreaking truth: At just 1.5°C of #warming (where we already are), 70–90% of #CoralReefs could vanish. At 2.0°C, almost all (>99%) are gone. We’re watching a living wonder cross a #TippingPoint. #MarineEcology 🧪🌍🌐🌊🔥

Australia's rainforests are the first to switch from carbon sink to carbon source, study warns The rising temperature, air dryness and droughts caused by human-driven climate change are likely the major culprits. #Rainforest #Australia #drought #carbonsink 🧪 phys.org/news/2025-10...

"Once citizens begin to view their own government’s security forces as an occupying army, violence becomes inevitable. Trump’s team knows this. In fact, that’s the point. They are not trying to restore order; they’re trying to trigger the very unrest that would justify further crackdowns." […]

🌿Using data from a biodiversity experiment, researchers show that N and CO2 decreased species diversity at various spatial scales, indicating potential for reorganization of grassland systems by increasingly favouring a small subset of dominant species🧪🌎

Do Brendan Carr (FCC Chair who threatened ABC over Kimmel) at the same time.

Honestly, he got it. This is an impossibly hard thing to get right. I can quibble about some parts, and it’s impossible to do normie content that’s also sufficient for the moment, but he did as good a job as is possible. Especially glad he rightfully called out the threat to journalists.

There is a really good study recently that explores deeply how COVID-19 infections causes insulin resistance/glucose intolerance. Essentially diabetes. Sadly I can’t post it because it contains the word “vaccine”… 🤦🏻‍♀️

Sunday 9/21 at 10am PT on Climate Chat: "What the Hell is Going On in the North Pacific?" with hosts Dan Miller & @leonsimons.bsky.social. On YouTube & LinkedIn. #ClimateCrisis #GlobalWarming youtube.com/live/BNZ_biC...

I’ll write it on toilet paper and post it on a notice board in my kitchen if I have to… But I’m going to keep publishing scientific research… and so should everyone that is out there investigating our universe… and helping us hold those in power accountable for wrecking it.

Can’t make this shit up

This… THIS is what got Kimmel taken off the air? THIS? It's not even about Charlie Kirk, it's about Trump! On a fake-outrage scale from one to ten, this is a hard eleven. Funny how Nexstar’s $6.2 billion acquisition of TEGNA Inc. was approved just thirty minutes after the Kimmel announcement!

My mom called me last night about the Kimmel firing, saying "This is how Hitler got started!" I quickly responded, "By firing the late night tv hosts?" Turns out, mom was right.

Group them all together & call it the Sanity Coalition.

Something something free speech! Something something….

Imagine being scared of diversity but not of a dictatorship.

Something something cancel culture something something. Uhhuh….

Extreme MAGA is trying to turn the Kirk assassination into their burning of the Reichstag moment. It would be hypocrisy if it weren’t roughly naked tribalism. They utter strings of syllables in simulacrum of principles, but their tribe/cult is their only principle. 1/
