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.

The world's corporations produce so much climate change pollution, it could eat up about 44% of their profits if they had to pay damages for it (phys.org)

The sentiment here is good, but be careful not to fall into the "personal responsibility" trap that the fossil fuel and soda industry established back in the late 80s/early 90s. The sad truth is that personal responsibility in solving climate change is wishful thinking. The carbon footprint of all of the major corporations is so many orders of magnitude larger than any plausible percentage of individuals who do their part by being as environmentally conscious as possible that it doesn't matter unless we regulate them and to do that we have to redefine the laws of campaign financing and abolish Corporate Personhood aka, Citizen's United for a start.

It's pretty bleak. Source: was going to be an Enviornmental Scientist and I decided that was too depressing and life it too short.
