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.

I probably make that much in my life. Billionaire make it in an hour, but environmentalists are still blaming me and the plastic straw I used last week

While plastic products do contribute to CO2 emissions, and billionaires do contribute a significant amount of their own CO2 emissions, plastic straws are terrible for wildlife and the environment altogether and should have been banned long ago for reasons completely separate from the CO2 emissions.

I know you write that to debunk the blame-shifting BS from the person above you and thank you for that. I would like to make a different point though: Plastic straws would have never become an issue if companies like McDonald's hadn't started to hand them out with every single drink for absolutely no reason. If they'd instead been used to allow disabled people to drink more comfortably, all would have been good. But consumers want, and in some cases, expect certain conveniences and companies are more than happy to feed our overconsumption.
