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.

You know what, it might be better. Less pollution, slower life, reduced digital addiction. Could also push new tech development not linked to fossil fuel.

That said, there's also a possibility where electricity becomes limited (it will) and only rich douches can use it.

Mains-level electricity might become rare, but solar panels are so cheap, ubiquitous, and durable that we'll have them for a while.

Plus every gasoline car has an alternator capable of 12v that can be spun by anything from a Sterling engine to a small child turning it by hand. There's billions of them. Unless we all forget how cars work we'll have at least some electricity.

You're not wrong and my comment is supposed to be jokingly.

I'm sure you used your example to show how easy it is, it just sounds so terribly distopian. Your point could have been an optimistic outlook into a different future but:

Why? Why of all things that can be used to turn an alternator, why the heck does it have to be child labor?

I took it to mean "even a child could do it!" rather than "we could make children do this."

All good mate! xD

I just thought it funny sounding, but understood what you wanted to say.

I could have said we put a dog in a treadmill to do it, like how we used to rotate meat on spits. But in my head I was thinking more of a parent using the electricity to do something and getting their kid to turn the crank.
