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 had no idea this was possible, a tipping point I never imagined. Sounds like many scientists were as ignorant as I, assuming the planet would cycle as much CO2 as ever. And now even that foot-brake is slowing?!

Fuck it. I can only do what I can do. Seen the ecosystem collapse in my region over the last 20-years, seen it collapse on my front porch in the last 4. Always shocking to me that no one is noticing the collapse in our insect populations, and amphibians, and reptiles, and fish, and mammals, and... Young people have no idea how fecund our environment was, even in cities.

I see less life in the woods than I did in my suburban hood in the 80s. And it was all the more lively in my parent's time. Ran into some rednecks 4-wheeling down to the creek the other day. Old lady seemed shocked I was swimming in it. "Hell naw I ain't goin' in there!" Well, lady, not many snakes or anything else. I was thrilled to see 5 fish, and only 1 was mature. And of all my trips there, that was the first time I'd seen more than 1 fish! (other than minnows)

We first-world people are so disconnected from the mythical "outdoors" that we think all is well as long as gasoline costs $X and eggs cost $Y.
