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.

Oh the earth will recover eventually! It's even possible humanity survives in some form!

Oh yeah Earth will be fine. It's survived worse than us and will be here long after we've died, almost certainly by our own hands. We aren't even the first mass extinction event to come from a mistake from within instead of an external force like a meteor but instead of runaway, macro-metastatic evolution. There was a blight of early trees in the carboniferous period that stored too much carbon leading to an ice age because the means of their efficient decomposition had not yet evolved, causing the opposite of what we're doing, leading to an ice age.

Life on Earth suffered, many species went extinct, as some do constantly even in good times, but Earth always recovers. We sadly fashion ourselves masters of this word rather than children and subjects, but we couldn't sterilize this planet if we wanted to. There's life in acid pools, in crevices we can't find, in depths we can't reach. Until the Sun's output changes enough in a couple billion years, life will most likely find a way here.

I take comfort, just as George Carlin did, in knowing that we will just be an evolutionary cul-de-sac, quickly forgotten by the living Earth we tried to dominate and rape as our private property.

The funniest bit to me is that for all the idiotic religions people kill one another over, demanding theirs has the largest penis and other believers of gods with smaller penises must convert or die, it was a rare thing indeed for humans to actually respect their actual God, their actual creator, the real one they can and do see every single day, the one we are, in objective fact, made of. Oh the dark irony of desperately seeking approval from a fictional "sky daddy" creator that we often anthropomorphize out of vanity to look and act and think like us, while raping, plundering, polluting, and defacing our true God as thoughtlessly as breathing.

Crabs will dominate the Solar System after any trace from our "developed society" is long gone.

Maybe they will have an religion of crab gods, but if gods go through evolution too, they are probably actually crabs.

Crabs rule!
