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.

Only a handful of those 8 billions actually impact the climate on an immense scale though.

what would happen if everyone turned around and said 'you know what, fuck companies that sell drinks in bottles i'm never going to be without my refillable bottle' how long would coca-cola keep producing 100 billion plastic bottles a year? what would they do with them?

But if James Quincey said 'fuck it, I'm not producing plastic bottles anymore they're bad for the planet' but 8 billion people said 'oh ok, well we're still going to regularly buy drinks in plastic bottles' the numbers of plastic bottles being made would dip slightly but only while Ramon Laguarta rushed to spend the flood of money now coming in to scale up production at pepsi co.

Yes. There's the possibility that people will actually change by acting in unison. But the probability for society to act in unison isn't really high. Just look at the world now. Some people can't even agree on weapons not being something you need to carry around 24/7. And you want them to agree on something that'd actually affect their daily life?

i could say the same thing about regulation, you really think if we can't even restrict guns you'll magic up the political will to ban something that would actually affect their daily life and earns so many companies so much money? coke pulls in 25b a year, they can afford all the lobbyists.

We need as many people as possible to have already moved away from them before we have the slightest chance at legislation.

The difference is that it doesn't need everyone to agree on one thing to make changes. "Boycott coke" requires a substantial mass to boycott one specific company. Demanding change from politics is much more broad and targets whole industries instead of specific things. Like bans on single use plastic, or pushes for EVs.

Apart from that, you most often have to create alternatives before people can abandon bad products. Could everyone stop using cars? Sure. Will it happen? No. But if we start to expand railway through politics, will more people abandon their car then cause they get around by train much more efficiently? Way more likely than without it.

I recommend Kurzgesagts video on the topic whether we can stop climate change. It goes exactly into this.
