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.

@silence7 I don't think there will be anything more than a rough estimate for the militaries, given that many are developing secret projects, or have their number of various vehicles classified.

But war, sadly, ads a lot to greenhouse gas emissions. Literally every single vehicle could at some point be set ablaze, and it doesn't matter how much that vehicle emits. It will just burn to the ground and all these rubber and plastic components will go in the atmosphere.

Also, explosions can set everything ablaze, not just vehicles. And it's also the modified terrain after the explosions, forests destroyed and if we also happen to bring nuclear weapons in the field, it's game over for the planet.
