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.

Culture is a bad excuse to prop up one of the worst industries for climate change though

I agree, just answering the question for those outside the US.

I know a lot of folks advocate a plant based diet. I don't think large portions of the US will be willing to do that. I think it is an easy sell to eat less beef and more other meats because it is cheaper and not a major diet change.

Now if we can get people to order online and go in instead of drive thrus....it is usually a lot faster too. Drive thrus suck because there is always someone who wants extra ketchup, exactly two pickles, 3 onion slices, half a cheese slice, and one drop of mayo.

Definitely true that people won’t go plant-based. I think we should be thinking about how to get lab grown meat into our food supply faster.
