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.

If Mother Earth doesn't kill us, the ICE agents will.

Don't worry, we will have a nuclear winter, so you're technically correct.

something something joke about disappearing glaciers being the real threat from ice something something

ICE can't kill us all. The climate change our politicians and corporations are resolutely ignoring certainly can.

Climate change can't kill us all unless we hit some strange runaway effect that wasn't triggered when atmospheric CO2 levels were higher 500 million years ago (although the sun was 5% less bright back then). There might only be a couple million people hanging out on tropical Antarctica, but they could survive.

Humans are hardy; our species survived the ice age and the accompanying desertification of Africa with just some sharp rocks, our species can survive a mass extinction event with all our modern science and technology.

No, if we die out entirely, it will be fascism that does it. Shitheads that would rather burn the last remaining footholds of human survival than let the future exist outside of their control.

Humans will survive, civilization won't. And since we already dug up and burnt all fossil fuels that are reachable with primitive methods, it might not be possible to jump-start development beyond medieval tech ever again.

Ice might kill us all if we muck up the environment more...

Even if they do pay attention to it, I think the global consensus is that it wouldn’t matter anyway… we are fucked.

[–] mech@feddit.org 8 points 1 day ago* (last edited 1 day ago) (1 children)

That's not global consensus at all!
That's just what the "we don't want to do anything" crowd pivoted to saying, now that you can't flat out deny the problem anymore.

If it wasn’t the global consensus, green tech would be free, because saving the planet would be more important than profit. Closing down cruise ships, private jets, etc.

The amount of progress we have made is next to nil on a planetary scale.

It’s great to desire it gets figured out, but don’t get your hopes up.

If a country made green tech free, the United States would organize a coup to restore fascism or some other capitalist order loyal to the US.

The world lives in fear of the US military-industrial complex. Even the USSR and China are/were defined by their relationship to the US. The USSR existing under embargo and struggling to support a sufficient military to ward off the US, and China only becoming a comparable power to the US by letting itself become the industrial heart of capitalism for over 50 years.

I am not saying that all the world's woes are the US' fault, I'm saying that ever there is a place in the world without woe, the US is there to rectify that existential threat to its hegemony.

Maybe after the US has finished committing murder-suicide by fascism, those of us who are still alive can start building for the future rather than for profit without fear.

The US is much more fragile than it seems. It was able to dominate the world by leveraging control of oil and currency to maintain the internal caste system. Fascism is expensive though, and it's already choking.

Genocide is a last gasp to maintain power. There is no way to prevent revolution, so the right is flailing. They believe that if they reestablish the "demographic distribution" that existed at their height, they can maintain power. Basically, they think they can ethnically cleanse the US back to the right. But that can't work. Nothing can possibly work because it's all over for them. So yeah, the US isn't going to last much longer... Especially now that they've nuked the soft power they used for so long to keep everything in check.
