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.

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.
