Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.

As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades: Graph of temperature as observed with significant warming, and simulated without added greenhouse gases and other anthropogentic changes, which shows no significant warming

How much each change to the atmosphere has warmed the world: IPCC AR6 Figure 2 - Thee bar charts: first chart: how much each gas has warmed the world.  About 1C of total warming.  Second chart:  about 1.5C of total warming from well-mixed greenhouse gases, offset by 0.4C of cooling from aerosols and negligible influence from changes to solar output, volcanoes, and internal variability.  Third chart: about 1.25C of warming from CO2, 0.5C from methane, and a bunch more in small quantities from other gases.  About 0.5C of cooling with large error bars from SO2.

Recommended actions to cut greenhouse gas emissions in the near future:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.

an American-Israeli company

Fuck that

Stardust told me it has no outdoor tests planned and that it will not conduct any until relevant regulations are established; its framework proposes extensive laboratory testing and computer modeling before beginning small-scale testing that they will “tightly monitor,” eventually scaling up to dispersing the particles across a wider area.

That's good at least maybe

I dgaf where it's from, can we please just stop with global shit like this that inevitably will benefit only a few rich?

[–] jol@discuss.tchncs.de 5 points 5 days ago (1 children)

Yeah, I have zero trust that they would test it in secret

[–] astropenguin5@lemmy.world 6 points 5 days ago* (last edited 5 days ago) (1 children)

Yeahhhhhhhhh \Or just somewhere with super lax regulations

I'm sure some authoritarian leader would welcome them with an open wallet.

Who are the clowns that invested in this idea?

[–] harmbugler@piefed.social 5 points 4 days ago

This seems like a scam that’s collected $60m so far. Hiding behind regulations lets them keep the scam going longer.

Right? Who's going to pay money for this "service"? How would you even monetize it? What country would pay money for it? Most countries wouldn't pay a dime unless everyone paid the same. The problem is that even if this was a positive thing, if you're Belgium, and france and Germany pay into it, you'll get the effects without paying. Unless you can make it specifically act for the "subscribers" nobody will buy. And even then, the gaps would make it so others who don't do it, will minimize the effect of those that do.

Logically it doesn't make sense. Let alone the scientific side, which we simply don't know. At best it delays the problem. At worst? Who knows.

If it doesn't make logical sense but it happens, that means you are making incorrect assumptions about the world.

Capitalism is very capable of creating commons that help its power structure, like public highway systems, the global positioning system, or the 2008 bailouts.

Having the continued habitability of the Earth depend on maintenance that only US megacorporations can perform is appealing to the US upper class.

Theough a Marxist lens, this is no stranger than workers going on strike and calling for a general strike. These investors are hoping to get their money back through capital class solidarity, likely in the form of massive investment and big government contracts.

I saw this TV show already. When does Elon start building the train that goes round and round the world?

No, now it needs to fuck off and die.
