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.

So were just supposed to celebrate milquetoast bullshit? Capitalism isn't going to fix shit

[–] Taleya@aussie.zone 26 points 9 months ago

How about you reward any action in the right direction because it ain't fucking happening normally no matter how many grand ideas you hold.

[–] Steve@communick.news 23 points 9 months ago

If you're going to wait to fix climate change, until after you've replaced capitalism first. You might as well work on taraforming Mars and sending billions of people on rockets instead.

[–] blazera@lemmy.world 10 points 9 months ago (2 children)

Hundreds of billions towards highways is certainly an action on climate

[–] silence7@slrpnk.net 22 points 9 months ago (1 children)

Not every action has been in the right direction, but on balance, the bulk have been.

[–] blazera@lemmy.world 3 points 9 months ago (1 children)

The bulk has been money to highways. Nothing else comes close

[–] silence7@slrpnk.net 20 points 9 months ago (1 children)

Yes, a lot of money is spent on things like repairing highways. "Just don't maintain the bridge" isn't a good move.

[–] blazera@lemmy.world 2 points 9 months ago (1 children)

Its poison for any effort to curb climate change. The concrete production alone is a major source of greenhouse gases, and its being done to further prioritize the single largest source of emissions in the US, personal vehicles. I cant think of a more effective thing to spend money on if the goal is to accelerate climate change.

[–] silence7@slrpnk.net 18 points 9 months ago* (last edited 9 months ago) (1 children)

Which is why the federal government is trying to buy concrete made in different ways that don't cause those emissions.

It's not at full scale yet, and won't be for some years. but it's how you actually solve that kind of problem without making peoples' lives worse.

[–] blazera@lemmy.world 4 points 9 months ago (1 children)

This shit is like clean coal. Its not a thing, concrete production involves releasing the co2 from calcium carbonate, not even mentioning the heating and fuel requirements that go into that process. These highways are going to be built with conventional concrete.

[–] silence7@slrpnk.net 12 points 9 months ago (1 children)

The problem hasn't been "you can't do it" but "architects and engineers don't have enough experience with it to trust it, so they don't use it" — a federal government purchasing program can fix that.

[–] blazera@lemmy.world 1 points 9 months ago (1 children)

You literally cant do it, its a chemical reaction that outputs co2. In the same way you cant run a combustion engine without producing co2.

[–] silence7@slrpnk.net 10 points 9 months ago (1 children)

You can use a different chemistry to make a hard substance. There are a ton of options which look good in tests, and pretty much nobody uses them.

[–] blazera@lemmy.world 1 points 9 months ago (1 children)

You are reaching far too deep to try and imagine this somehow turning out alright for the climate. The hundreds of billions are budgeted already. Highway construction is happening. Conventional concrete is being used. Truck and SUV sales are increasing to fill the new highways.

[–] silence7@slrpnk.net 10 points 9 months ago

Vehicle sales remain below pre-pandemic levels

I don't deny that conventional concrete is still being used at scale. It's something like 1% of US emissions.

Said below an article about the good things Biden did. Yup.

[–] blazera@lemmy.world 2 points 9 months ago (2 children)

They always say the same thing, some declaration of passing the greatest most stupendous climate legislation of all time. The climate legislation that sold millions of acres of federal land for oil and gas extraction.

[–] Taleya@aussie.zone 11 points 9 months ago (1 children)

Dudes pushed more progression than obama and done it with a hostile senate. Get your head out of your arse and try looking at reality.

[–] blazera@lemmy.world 3 points 9 months ago

The reality is that bill mandated the sale of a lot of federal land specifically for oil and gas extraction, and that US oil production continues to increase with no peak in sight.

[–] someguy3@lemmy.world 7 points 9 months ago (1 children)

There is it again: B b b b Biden bad!1!

[–] blazera@lemmy.world 2 points 9 months ago (1 children)

You gotta try even harder to say it in a dumb sounding way for it to work

[–] someguy3@lemmy.world 10 points 9 months ago* (last edited 9 months ago) (1 children)

Nah it summarizes everything quite well. No matter what's done, all you say is Biden bad.

[–] blazera@lemmy.world 2 points 9 months ago (1 children)

Whats amazing is youre the only one thats said it

[–] someguy3@lemmy.world 8 points 9 months ago (1 children)

Your rebuttal is that multiple people have to say it to you? Frankly, lol.

[–] blazera@lemmy.world 2 points 9 months ago (1 children)

No, youre claiming its all i say. But i havent, only you have.

[–] someguy3@lemmy.world 7 points 9 months ago (1 children)

So your rebuttal is an intentional misreading and bad faith argument. Again, lol.

[–] blazera@lemmy.world 3 points 9 months ago (1 children)

What are you talking about faith in arguments, coming in here with the classic "this is you sounding stupid!1!"

[–] someguy3@lemmy.world 5 points 9 months ago (1 children)

Again that's a (very good) summary of your comment. You even agreed! You said "very" in response.

[–] blazera@lemmy.world 1 points 9 months ago (1 children)

Especially the 1's mixed in.

[–] someguy3@lemmy.world 1 points 9 months ago (1 children)

That's not a rebuttal at all that it summarizes your comment and that you agreed.

[–] blazera@lemmy.world 1 points 9 months ago (1 children)

I agree hes bad. It doesnt summarize anything i said tho.

[–] someguy3@lemmy.world 1 points 9 months ago* (last edited 9 months ago)

Another intentional misread and bad faith argument!

And yes it does summarize what you said.

[–] goferking0@lemmy.sdf.org 8 points 9 months ago

please ignore sudden tarrifs on EVs, batteries and solar panels as we hope capitalism solves the crisis. We can throw them money and they'll do it like when we did that to have isps expand internet access and infrastructure

Decarbonization is a worldwide multi-decade project. It's not something that any one politician or country can do on its own.

[–] Instigate@aussie.zone 4 points 9 months ago

This is an argument I’ve been pitching in the Australian context for some 20 years now - we should have been world leaders in solar technology, to the extent that by now we should have massive solar farms across the North of Australia in order to export clean, green energy up to Papua New Guinea, Indonesia and other near-neighbours. We could have created a whole new industry of both research and advanced manufacturing, and if we’d nationally sequester our resources correctly we could be doing every step of the way - dig out the minerals, refine them, manufacture them into panels, export those panels - all the while generating very low cost energy and exporting it for profit as well! Not to mention so many new jobs!

Even once you take away all of the obvious arguments for climate change action (environmental, ethical, prevention of future disasters etc.) there was always going to be a strong financial incentive in a capitalistic market to move to technology that has the lowest input cost to generate energy, which just so happens to be renewables. It just baffles me that so many politicians crucified themselves on the altar of coal when they could’ve been remembered for ushering in simultaneous economic benefit and environmental benefit, with a long term impact of lowered inflation through cheaper power bills, but that’s what the minerals lobby in this country has managed to achieve. What a disgrace.

Good to see a world leader using the economic arguments in addition to the other more obvious ones.
