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.

It's not only cars, there are power plants running on oil, nearly every "small" backup generator runs on diesel. Also logistics, trucks, trains and ships needs boatloads of diesel.

The person you're replying to said that if people stopped driving cars, companies would sell less oil.

You seem to disagree, and your argument is that energy and shipping use oil.

Are you saying that a carfree world would consume exactly the same amount of oil, because it still has energy and shipping?

I had the wrong assumption that cars consumed nowhere as much oil as those things. Turns out I was dead wrong - https://afdc.energy.gov/data/10661
