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.

Not wind with sodium ion batteries. EDIT: Source

EDIT: This comment is based on outdated information (see the below thread). A growing number of wind turbines are switching from electromagnets to permanent magnets, the latter of which use rare earth minerals. You could still make wind turbines with electromagnets, but that does likely give countries with rare earth minerals a competitive advantage.

What is the generator made of?

Batteries aren't an energy source but a storage.

Here is a more direct link.

Apprently my information is outdated. For a long time, wind turbines used electromagnets (the fact check is from 2016), but it looks like they are starting to use permanent magnets now (which require rare earths). They still don’t need them, and I think a lot of the ones using permanent magnets are from countries which have rare earths, but I will update my initial comment since I don’t want to move the goalposts.

In any case, there is a commenter above that mentioned solar, which according to my link does not need rare earth minerals.

I think the world bank report is a good read, regardless.

What if you use a pully and have the generator on the ground?
