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.

This is not a problem individuals can solve at home

excuse me but, while the US torpedoed an Iranian oil tanker in the strait of Hormuz I was able to recycle 17 aluminum cans.

Yeah thats sort of what I was complaining about. We, as a group, don't care enough to take collective action. I'm doing my thing, I'm not doing it because I think I'm going to save the world, I'm doing it because I think its the right thing. I'm not under the illusion that me or my friends can change the world. The point I was making (very badly), was that they are not interested in doing even the minimum, so theres absolutely no hope for getting any bigger changes done.

I'm kinda similar. I think it helps because you need to show people what a greener world would actually look like. The train is less intimidating if a coworker can answer all your questions.

We can get rid of all the data centers and everyday life would be pretty much the same. With cars it's another story, and the average person has less imagination than you're imagining.

Hmm, yes, good point, about showing and answering questions.

When I was 15 to 28ish, I was the guy who was into cars, went everywhere with a car, heck, I had like 7 cars at one point. Now that I'm not that guy anymore, I find myself answering questions about getting rid of all the cars and stopping driving. A few people have gone "huh, I guess its not that bad" when I tell them how easy it is to go from spot A to B with a bus. I guess its a sort of "lead by example" kind of thing.

Most countries don't even have enough climate conscious candidates to form a government if they were all elected
