people betting huge sums on other people's death is some straight-up black mirror shit

but the person dying and then the betting firm finding a fine-print loophole to not pay them anyway is what elevates this to high art

I doubt it's a coincidence that this happened the day after Rep. Gonzales was forced into a runoff in his primary.

The House GOP leadership must have realized he can't be saved from this scandal* and it's better to replace him now than have him get beaten in the fall.

Direct human health risks of increased atmospheric carbon dioxide - Nature Sustainability A review of studies on exposure to elevated CO2 concentrations in air suggests that health damages, such as inflammation or reductions in cognitive abilities, can occur at levels as low as 1,000 ppm.

Results are accumulating that exposure to CO2 has heatlh effects at lower levels than previously thought, but we're not going to drop dead at such levels. @joeallenjoe.bsky.social can better speak to this topic.

How Talks Between Anthropic and the Defense Dept. Fell Apart

NYT’s reporting on the DOD-Anthropic dispute sheds more light on how the Pentagon planned to use Claude for mass surveillance of Americans: by collecting and analyzing commercial bulk data.

So what is this commercial data? And how might Claude be used to collect and analyze it? 🧡 1/

This paper is excellent and shows how the fossil fuel industry deploys false solutions- CCS, hydrogen, and CDR- in order to further entrench and protect fossil fuel hygemony

I do recall seeing some stuff about in the midst of the pandemic.

I'm not going to try to figure it out. Perhaps, @linseymarr.bsky.social or @corsiaq.bsky.social have some insight on [CO2] health impacts on humans.

Here's another one showing cognitive effects: Satish, et al.. 2012. "Is CO2 an indoor pollutant? Direct effects of low-to-moderate CO2 concentrations on human decision-making performance." Environ Health Perspect. vol. 120, no. 12. Dec. pp. 1671-7.

Thanks for this. Other studies show different effects, but this looks like a credible one.

I've read that, but I've also read contradictory stories about submariners operating at a couple times that concentration.

These limits are for toxic effects, but Joe Romm cited studies indicating reduced cognition at 1000 ppm.

NIOSH REL (recommended exposure limits)
TWA 5000 ppm (9000 mg/m3) ST 30,000 ppm (54,000 mg/m3)

OSHA PEL (permissible exposure limits)

This says nothing about the study you cited, though.

I remember Joe Romm citing toxic effects of CO2 above 1000 ppm but don't have the refs handy.

This is respectfully disingenuous beginning with which viewpoints they overwhelmingly choose to platform and hire on the opinion side.

In addition to that, there's a difference between sharing viewpoints you disagree with and sharing viewpoints that are based in lies.

Probably also missing rooftop PV, which is tracked separately from power system generation.

US electricity generation changes, 2024 ➑️ 2025:

Coal: ⬆️ 67 TWh (13%)
Oil: ⬆️ 2 TWh (19%)
Gas: ⬇️ 41 TWh (-4%)
Nuclear: no change
Hydro: ⬆️ 6 TWh (3%)
Other renewables: ⬆️ 13 TWh (11%)
Total: ⬆️ 47 TWh (2%)

Big story is coal generation rising A LOT (67 TWh, 5x renewable growth), mostly displacing gas.

Clear fucking messages that include zero 0️⃣ words of support for any aspect of it much less starting by praising one of the main outcomes, Jesus.

They were going to pass rules to phase out gas stoves, until they received 20,000 public comments against the regulations. Except, oops, it turns out the comments were generated by AI.

Exclusive | U.S. Power-Plant Pollution Rose Sharply in 2025 The increase was a rare uptick in an otherwise long-term downward trend, partly because of more coal being burned to generate electricity.

Explosive, exclusive article in Wall Street Journal, documenting some of 1st results of Trump rollbacks:
