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.

Which should have begun 20 years ago, but here we are.

Yes here we are, because people 20 years ago complained that this should have been solved during the oil crisis and did not proceed to actually change it in their time.

Humans are basically useless.

"They never did what was necessary, so why should I?"

"They aren't doing anything right now, so why should I?"

"I'm not going to personally experience it, so why should I do anything about it?"

"I probably won't personally experience it, so why should I do anything about it?"

"Doing something is 'too hard', 'too expensive', or 'too something', so I'm not going to do it!"

"Doing something is immoral or unethical in my personal belief system, so I'm not going to do it!"

Add it all up and it's basically impossible to get anything done without powerful (and rich?) ideologues. The challenge, which democracy was supposed to solve, is how to put those people in place without bloodshed.
