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.

What happened in the 80s? Seems the temps were all sorta within a pretty standard deviation until then.

Who left their heater running?

Iirc, if you're 60 today, around 75% of human CO2e emissions were created during your life time. The number may be a little off, but the point is: since emissions have steadily increased, it's very likely that the majority of emissions were emitted during your life time. Which also explains why shit is getting crazier very right now, as emissions are on a level never seen before and still rising.

This is why I think we need to have global battle Royales. Thin the herd. Keep the population lower so we don't have to work the earth as much.

Maybe a nuclear war and the following nuclear winter would be a good reset for ol mother nature lol.

Population is not even the issue here. We are capable of sustaining the amount of people we have we just refuse to do so efficiently because it benefits rich people.
