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.

Until you start bringing up the lithium mining receipts.

Does lithium mining inherently push GHG into the atmosphere? I'm honestly asking because I don't know much about the process other than it requires significant amounts of processing to extract lithium from its surrounding deposits. But if the source of emissions for lithium mining are solely from powering the equipment, it is not really a climate change issue (though even localized environmental damage is bad and needs to be addressed, of course).

Traditional lithium rock ore mining is a dirty, polluting process that also uses huge amounts of fresh water. But that’s not all necessarily inherent. There are several projects around the Salton Sea in California that promise not only to extract lithium cleanly, but also to generate a lot of GHG-free electricity along the way, because the ore is hot salty corrosive water extracted from deep underground. optimistic podcast episode 1 podcast 2 website article

Good thing we’re moving to sodium ion then I guess. Also good that lithium batteries can be recycled so less lithium has to be mined. Can’t say that about coal, oil, or natural gas.

And oil mining is more ethical?

[–] Jax -1 points 4 days 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.

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.
