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.

Yeah-yeah-yeah. What about the economy though?!

[–] frunch@lemmy.world 35 points 7 months ago

I'm also seeing a troubling lack of consideration for shareholders too 🤔

Well everyone and everything dying will be terrible for the economy long term. But the more important question is: will line go up this quarter?

[–] rammer@sopuli.xyz 2 points 7 months ago

Of course it will. It doesn't have to have anything to do with the "real" world. And it hasn't for a while now. Because the line must go up.

[–] OpenStars@piefed.social 35 points 7 months ago (1 children)

I see your:

grim calculations for humanity if climate change and growth in population and consumption fueled by cheap energy goes unchecked.

And raise you a:

Number must go up‼️

You are going to be SO tired of all that "winning"...

Wouldn't that be "most" at the 6Billion point?

[–] neons@lemmy.dbzer0.com 19 points 7 months ago* (last edited 7 months ago) (1 children)

That would probably fix our emissions as well.

I just wish it only extended to humans.

How many of those deaths are suicides?

[–] RememberTheApollo_@lemmy.world 15 points 7 months ago (1 children)

If the system collapses most of them will be starvation, exposure, or murder.

[–] veganpizza69@lemmy.vg 10 points 7 months ago (1 children)

You forgot the rampant diseases.

[–] RememberTheApollo_@lemmy.world 7 points 7 months ago* (last edited 7 months ago) (1 children)

Yeah. Didn’t want to get in the weeds over such a depressing subject. First to go will be those dependent on medication and medical life support for survival, like insulin. Then next will be those without access to clean water, they’ll pick up pathogens and die soon when coupled with the lack of food. Then lack of food and exposure to cold and excessive heat will eat away the rest, along with infections and other diseases, and attacks by other humans. I don’t know that I ever understood peppers because the vast majority of them seem to assume some form of society would re-emerge, but if society ever collapses to the point where one actually needs to hole-up and wait out whatever calamity happened then there won’t be a civilization left. They’ll live long enough to die of an infection or other illness, or their supplies run out. Fuck knows that nobody will likely survive in a group containing the skills to build farmland and have enough animals like a 1600’s village to survive. Think of the support network they had even then that wouldn’t exist. From smiths to charcoal suppliers, sheep and wool, draft animals, etc. Peppers would survive to be the king atop a dead planet.

If the climate isn't stabilized, farming isn't going to work out (and neither is pastoralism). The unpredictable seasons affect domesticated ecosystems as well as wild ones, that's already starting. Gathering is going to be very tricky too. Overall, these human populations, even if they survive, would have a larger chance of dying due to bad unexpected thing, which looks like extinction over a longer timeline as the isolated populations die out. And if anyone mentions hunting, laugh at them.

I plan to die violently pooping at something or someone

important question: will i be one of those six billion

[–] onslaught545@lemmy.zip 5 points 7 months ago

Are you wealthy?

[–] Gowron_Howard@lemmy.world 6 points 7 months ago

Who will do all of the work for the ruling class then? Not them certainly.

[–] Olgratin_Magmatoe@slrpnk.net 5 points 7 months ago (1 children)

I hope to be dead before the water wars start.

[–] rammer@sopuli.xyz 6 points 7 months ago

They've already started. But they've been happening where it doesn't matter much to Western media.

Except Israel-Palestine. Where water has been used as a weapon. But has been brushed aside by other issues.
