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.

Also, it's kind of unfair to be equating each of those items because not all of them were actual actions taken to address the problem, and the actions are not equivalent or involve every country. The most substantial actions have only been taken recently, and no one promised that this train could be stopped in a few years.

But it shows us that these big climate summits don't really do anything, apart from generate even more pollution from private jets... They are just a big show to create the illusion of governments giving a shit.

Another interesting factoid, is that the USA does not include it's military emissions in its annual emissions reports, as that would reveal "classified information"..... The military industrial complex must fall, but that's most of the US government lol.
