Climate - truthful information about climate, related activism and politics.

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.

No. If you think they are, then please look up how much of the plastic in the oceans and nature in general is from car tires. Also an electric car does nothing if the electricity is produced from fossil fuels,

Incorrect, evs are still better than petrol, even under coal power, so it does do something. Also the grid will continue to get greener as coal shuts down and EVs will get greener too.

Also there are plenty of additional studies showing this too.

Actually, because of just how inefficient small scale combustion is and how much fuel goes into getting that gas to the car in the first place, even if you run an EV directly off the most polluting coal plant in the North America it’s still significantly better for the environment. Admittedly if you use a more average energy mixture, the benefit is far larger, but there is still a benefit.

Make them float with anti gravity instead of giving them tires? By the stars, the apes of this star system have so many skill issue problems...
