I believe I’m not the one making assumptions here…

If they created the same number of jobs they eliminated within the same company they would be pointless.

It’s not obvious that more jobs will be created in other sectors, as they are all automating as well.

But go ahead and linearly extrapolate a nonlinear situation. Nobody will stop you.

The core error:

Separatists doing "easy math" treat federal taxes as "lost money" instead of the cost of operating a country.

You wouldn’t eliminate a level of government.

You’d replace Ottawa with Edmonton. (Or Washington, DC, who would have even greater control over natural resource revenue.)

An independent Alberta would need to fund:
β€’ National defence
β€’ Border services
β€’ Foreign affairs & trade
β€’ Immigration
β€’ Higher level courts
β€’ Aviation regulation
β€’ Debt servicing
β€’ Central banking, etc.

This stuff is also conveniently left out of the "-$23B" fiscal balance calculation.

In practice, I gather that houseplants don’t freshen the air in your house enough to make a big difference, as I suspected.

It turns out that many people have taken this on and therr’s a plethora of answers depending on constraints.

Of course the lifecycle of a plant is exactly carbon neutral if the remains of the plant are allowed to decay. In your sealed environment you would want to eject dead leaves and dead plants.

Wife just raised question of indoor plants. How much carbon does an individual exhale, and how much does a houseplant take up? Which houseplants work best? How many plants needed in a perfectly sealed environment?

My intuition: it’s impractical but I’m guessing.

Again from memory only but I think direct toxicity is barely detectable at ten thousand ppmv, and that places like schools and office buildings often register in the 3000 ppmv range. Which is why we like openable windows even in the 420 ppmv world.

yeah i think anything in the range 600-1000 is considered okay. the paper does mention time spent indoors as an area of consideration/further research so at least they didn’t ignore it but the methodology doesnt seem to factor that in.

01.03.2026 14:49 πŸ‘ 1 πŸ” 1 πŸ’¬ 2 πŸ“Œ 0

I don’t have numbers handy but I looked into it once. If I recall right indoor CO2 concentrations are very typically 1000 ppmv which would likely overwhelm a trend of a few tens of ppmv outdoor ambient over a multidecadal time scale.

Haven’t read the source paper but can imagine them missing this.

01.03.2026 14:42 πŸ‘ 1 πŸ” 0 πŸ’¬ 1 πŸ“Œ 0

I am concerned that they didn’t mention high CO2 exposure indoors. Both indoor time and indoor CO2 concentrations are likely rising (due to better insulation). Indoor CO2 is known to be much higher than outdoor ambient levels.

01.03.2026 14:31 πŸ‘ 4 πŸ” 2 πŸ’¬ 2 πŸ“Œ 0

I have trouble with this report - attributing serum CO2 to increased ambient outdoor CO2 makes little sense when many people spend most time indoors at much higher CO2 levels. Wouldn’t the trend be more likely due to more time indoors in more tightly sealed buildings?

The world could be such a nice place if we allowed it. It's all so goddamn unnecessary. There's no need for any of it. It's so beautiful here. It should be so cool to be alive

So, what's Poilievre's take on this? Is he going to be anti-war just because Carney has shown surprising hawkishness?

I think that the lack of substance to the negotiations was obvious, frankly.

There are plenty of other terrible things about generative AI but overall my objection to it is spiritual and I just can’t really get into arguments about that. That objection doesn’t extend to every use case for it, but as far as generating anything β€œimaginative”, those are all graven images to me

Never forget, when you’re being asked to prove that safe bike-lanes or pedestrian crossings across currently unsafe conditions are β€˜needed,’ it's hard to justify a bridge by the number of people swimming across a raging river.

But the problem is not skepticism. Nor is it only that anyone can create and widely distribute a faked image. It’s that this ability has given everyone a permission structure to doubt. Everyone, in other words, has been granted license to choose which images they will and will not believe, and they can elect to unsee an image simply because it doesn’t confirm their priors: the mere possibility of its algorithmic generation opens it to suspicion.

Here the phrase is once again in something I've written. You would never agree to *choosing* to disbelieve a photo. That would be preposterous. But you want to disbelieve it. Well, AI lets you do that now.
