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.

just to maybe say what that other person said in a different way:

carbon isn't emitted at the point of consumption, it's emitted at the point of production. if you don't buy a new phone or a plastic toy the carbon from its production doesn't go away it's already been released.

and before i say this next part i want to stress that boycotts don't work except when paired with other more militant movements.

if you and everyone else stops buying a new phone or a plastic toy then the factory doesn't close down and get rehabilitated, it changes hands and the new owners make something with less environmental exposure, like plastic pipes or mine detonator circuit boards.

the way to stop our emissions is at the point of production globally, not at the point of consumption individually.
