The solution to global warming is to artificially heat earth to Planck temperature, this ensuring it cannot possibly become any hotter.

How does the saying go, the only thing that can stop a bad air pollutant with a gun is a good air pollutant with a gun?

[-] Tollana1234567@lemmy.today 1 points 3 hours ago

wouldnt it be easier to have more photosynthetic organisms, like ocean algae and rainforests.

[-] Allero@lemmy.today 1 points 1 hour ago

This is an ironic post

Obviously ocean algae and rainforests are superior

Even if this would work without any complications from increasing atmospheric pressure, electrolyzing 0.5% of the ocean with present-day technology would take more than 200,000 years. That's plenty of time to invent new tech to speed it up, but even if some miracle invention next week sped it up by 2 orders of magnitude, it would still take more than 2000 years. So in feasibility terms I would rate this concept lower than building space elevators to save rocket fuel.

Cool sci-fi concept tho - let's get Arnold on it right away!

More dense atmosphere means strapping some feathers to your arms and flapping like a bird could actually work.

[-] Noja@sopuli.xyz 21 points 10 hours ago

This would work best in an atmosphere of tungsten hexafluoride, which is the heaviest gas in the world. It's ~11 times heavier than air. The downside is that you would melt down to a brown sludge.

[-] LovableSidekick@lemmy.world 12 points 8 hours ago

It's the sludge part that really throws a wrench into it for me.

[-] krashmo@lemmy.world 2 points 8 hours ago

Sounds like a win to me

[-] PotatoesFall@discuss.tchncs.de 29 points 11 hours ago

Wait how does Hydrogen -> Ozone?

[-] Tudsamfa@lemmy.world 20 points 10 hours ago

It doesn't... I may have replaced the wrong text.

In any case, what would you say is the best property of having more hydrogen gas in the atmosphere? Make it quick, I need to sell a few pentawatthours to world leaders.

Capture it and use it for nuclear fusion.

Then capture the helium produced as a byproduct and use it to build a city supported entirely by weather balloons

[-] Enkrod@feddit.org 1 points 1 hour ago

Human fusion technology currently only works with heavy hydrogen isotopes (deuterium and tritium in neutronic fusion). Fusion of normal hydrogen requires pressures and temperatures we're unable to control at the moment.

Aneutronic fusion is currently explored in fusing hydrogen and bor, this results in clean helium-4 and no neutron radiation, meaning it leaves no radioactive waste. But it needs temperatures FAR exceeding the core of the sun and it's self-cooling via Bremsstrahlung, so it's nowhere near a working technology.

We can react the hydrogen with CO2 in the atmosphere to produce hydrocarbons and water. The water goes back into the electrolysis system, and the hydrocarbons can be put back underground where they belong. As a bonus it gets rid of some extra CO2!

[-] ryannathans@aussie.zone 6 points 7 hours ago

Hydrogen is its normal state exceeds the escape velocity of Earth

[-] anton@lemmy.blahaj.zone 13 points 10 hours ago

It floats up and gets striped first by solar winds, like a shield protecting the ozone layer.

[-] LibertyLizard@slrpnk.net 9 points 10 hours ago

I don't think adding other gases will reduce the amount of radiation carbon dioxide absorbs lol

[-] Tudsamfa@lemmy.world 1 points 23 minutes ago

But the scary news are always "Carbon dioxide reached 430 parts per million". So I thought instead of reducing the carbon, we could increase the "per million" for the same effect and have no scary news any more!

[-] deranger@sh.itjust.works 0 points 9 hours ago

It will dilute it and reduce the effect, sorta like reducing the reflectivity of a mirror.

[-] LibertyLizard@slrpnk.net 9 points 9 hours ago

I don't think so. There's still the same amount of carbon between the earth and space, so it's still going to have the same effect of blocking IR that's moving to escape the earth's climate system.

If anything the extra gases will simply trap more heat on their own, although probably less so than the CO2 does.

[-] deranger@sh.itjust.works 2 points 9 hours ago

The concentration matters, not the absolute amount. Spectroscopy confirms this. 1g of CO2 will reflect IR much differently if it’s in 1mL or 1L of volume.

[-] mangaskahn@lemmy.world 7 points 8 hours ago

The volume doesn't change. It's still the same amount of CO2 in the same volume. There's just more of the other gasses in that same volume.

[-] ExLisper@lemmy.curiana.net 2 points 3 hours ago

Since it's not clear what will happen let's just try. What could go wrong?

[-] deranger@sh.itjust.works 5 points 8 hours ago

I don’t know enough about planets and atmospheres to say for sure, but I reckon adding gas would increase the volume of our atmosphere to some extent.

[-] LibertyLizard@slrpnk.net 5 points 8 hours ago* (last edited 8 hours ago)

Well I'm no expert but that does not make sense to me. I don't think CO2 is reflecting IR but rather absorbing it.

Not sure where I can read more about this to confirm or deny this idea.

[-] deranger@sh.itjust.works 2 points 8 hours ago* (last edited 8 hours ago)

It’s absorption and re-emission of IR. Instead of IR leaving our planet, some gets redirected back at the surface by CO2.

[-] teft@piefed.social 8 points 10 hours ago

Ok, ok, ok. But hear me out. Instead of ozone, zeppelins!

[-] Allero@lemmy.today 1 points 1 hour ago

What could go wrong, I wonder

[-] Elting@piefed.social 5 points 10 hours ago

HUH?!! WHATS THAT? I CANT HEAR YOU OUT OF THE BLOOD IN MY EARS.
