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.

And less vegetables, which are responsible for the other 70% of emissions.

Well, you need to eat something. But I guess after reducing meat, the next best thing would be fighting food waste.

One of those solutions should be recycling food waste into fertilizer. It’s ridiculous that all of those nutrients end up in landfills.

Many countries do have organic trash recycling. I'm not sure what they do with it though. Biogas?

Man, I'm tired of humanity min-maxing.

Sometimes it feels like everything we do, we compulsively scale it until resources are depleted and ecosystems collapse.
And because everything is globalized, that resource/ecosystem ends up being our whole planet. Anyone who does not participate, gets fucked anyways.

Without repeated optimization and limitless expansion, how will shareholders see the expected indefinite perpetual growth of their investments?

Put it in balloons and call some hippies?

[–] Pat_Riot@lemmy.today 1 points 3 weeks ago (1 children)

More like call some ravers.

[–] disguy_ovahea@lemmy.world 1 points 3 weeks ago (1 children)

Both. I take it you’ve never been to a Grateful Dead or Phish show.

Nah, I got no patience for 20 minute renditions of songs that are 3 minutes on the record.
