New strategy to prevent global warming: just freeze all of the CO2 out of the air!
Comment on Half as Hot

30°C is 303 Kelvin. Half of that is 151 Kelvin, which translates into a fairly mild -122°C!

That’s one of the ways proposed for terraforming Venus. Put in a sun shield to freeze the planet, let the CO2 snow down, then process the CO2 into something that can sequester it away so it doesn’t just go back into the atmosphere after removing the sun shield.
Of course none of that is technically possible right now, but it’s a lot easier on a planet that has no (known) life to destroy while working through the process.

the sequestering step is actually kinda easy, it’s the sun shield that’s the hard part

That sounds great. I bet it would be even easier to do on earth. If anyone gave a shit.

Dry snow doesn’t sound like too bad of a proposition on its own.

Wait, does it? Are joules in thermal energy per kelvin a purely linear relationship?
Verat@sh.itjust.works 4 weeks ago
For the most part, it varies by material and state of matter, but assuming the chemical composition doesnt change and no material changes phase, then it is effectively linear.
PmMeFrogMemes@lemmy.world 4 weeks ago
hmm but there will surely be a lot of phase changes with a drop in energy so substantial. we need our top scientists on this asap

Aka a cool 272 Rankine for our US folks.
MisterFrog@lemmy.world 3 weeks ago
I would be willing to bet there are more people in the US using Kelvin in their jobs than Rankine.
Lb-mole? That one I’m not sure.
To me, these wanna-be scientific units are weird, like, just use metric at that point 😅
Also 1000th of an inch. Like, come on! You’re just teasing us
