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.

As much as this news disturbs me .... the thing that disturbs me most is that most of the world will ignore it.

Humanity won't do anything about any of this until millions die and mass migrations start happening due to extreme weather events.

COVID was the perfect microcosm for climate change action. COVID killed a shit-pile of people really quickly. Humans are wired to acknowledge pressing matters (like a pandemic), while more abstract concepts, and things with delayed consequences get pushed to the wayside.

It make sense, why we are the way we are. Who cares about where your meal next week is going to come from, when you're a caveman running from a lion?

Does it make us any less dead? nope. Just the timing is in question.

Even covid was already too hypothetical and abstract and too far away in time and space for millions of people to act cautiously. Climate change is further away still... When it becomes very noticeable, it's far too late: hawaii fire level stuff before people actually realise it's fucked.

Hawaii fire level stuff is due to climate change.

the number of chuds I've met that really, really think it was some kind of space laser and not a wildfire driven by hurricane winds and crippling heat is fucking depressing. people I volunteer with who I thought were rational humans... what in the fuck

[–] freebee@sh.itjust.works 4 points 11 months ago

Yes. I meant many people only realise it when they are the one stuck there and can't get out.

Humanity won’t do anything about any of this until millions die and mass migrations start happening due to extreme weather events.

We won't do anything even then.

Well, not anything that'd help, at any rate. The worse things get, the more people will vote for conservatives and populists who will sell them easy solutions, which will likely consist of mass violence and rolling back environmental regulations because they inconvenience their voters. The only thing that will actually help will be the inevitable collapse of industrial society at this scale, but to get there hundreds of millions if not billions will die pointless deaths, especially if nuclear weapons are involved in the collapse.

At this point I want collapse to hurry up so that the old fuck boomers have to deal with it.

It's already basically too late and once millions die it will be super mega too late no take backsies.

Dude I'm way passed it. I'm hoping to collect on my new beach front property and live large.
