Climate - truthful information about climate, related activism and politics.

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.

New research finds that certain packaging materials can show 70% lower emissions than alternatives.

Yep, just as neutral and useful as all the research on how cigarette is "not that bad", conducted by Marlboro and friends

Oh man... I was about to comment satirically "this study was sponsored by coca-cola" but then I read your comment.

Sometimes it seems like there is no more need for satire, because reality has become a joke itself.

The entire basis for this is the assumption that goods are being transported using fossil fuels. If we transport the goods using electric trucks suddenly plastic starts to look much, much worse than paper or even glass.

Aluminum is much better all around so I'm not sure why it's lumped into everything else. It's basically infinitely recyclable and you don't have to use natural gas or propane to heat it up to the melting point for forming/extrusion. There's basically an infinite amount of ways to heat things up; even to really high temperatures.

There are complexities when dealing with aluminum. Main one being oxygen.

You don't want aluminum oxide, you want pure aluminum. Just heating the stuff up on its own will not give you pure aluminum. You have to eliminate oxygen from the equation.

Edit: Any wonder why aluminum welders have fat bank accounts?

Alu is very expensive to produce due to how much processing it takes—which also includes requiring a ton of energy and water, IIRC.

Until you start bringing up the lithium mining receipts.

And oil mining is more ethical?

[–] [email protected] 1 points 2 months ago (1 children)

Oil mining is a more urgent issue, yes, but polluting the land with exhausted lithium mines is not the way to divest.

[–] [email protected] 2 points 2 months ago (1 children)

The thing with lithium is, that it can be recycled. Can't say that about coal (etc). Lithium mining is absolute trash, but I hope that we can improve on this.

I understand why it's considered better, I'm merely elucidating the importance of recognizing that it's a stop gap measure.

Yes, because I prefer plastic over glass in my testicles..

[–] [email protected] 2 points 2 months ago (1 children)

I prefer only testicles in my testicles.

To that end, I propose a new packaging system!
