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.

You don't think someone making 65k living with a smart phone, car, AC, electric heat, using goods like toilet paper, hot water, plastic, crafted metals, etc. produces more pollution than someone in the 90th percentile wealth in a developing country?

This.

The way to know where you are in the pollution impact is if you drive a car you're in the top 10%. If you regularly fly you're in the 1%, and if you fly a private jet you're in 0.1%

Why rich people use so much more energy: It’s mainly all the traveling, says a comprehensive new study. https://www.vox.com/energy-and-environment/2020/3/20/21184814/climate-change-energy-income-inequality
