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.

If you aren't the US or china you can't do anything that will actually move the needle. Here in nz we're trying to reduce emissions as if our 0.00001% global reduction is going to make up for the fact that the increased cost caused manufacturing to go to china and get produced and shipped back at 100x the emissions.

There needs to be a global catastrophe to sharply halt emissions. Even china reducing by 10% wouldnt be enough since the damage compounds year on year.

That being said I do try to keep my emissions down and buy low emission goods in hopes enough other humans think the same.

Yeah I just try to keep the local area clean, traffic free and stuff like that. My motivations are not saving the world, its to make my city a bit better.
