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.

Of course. This will hold back humans getting off the planet for thousands of years. We got kind of close this round, will probably need another 3000-5000 years before the rock is left behind.

good. Humanity should rot in this hellhole. Other solar systems are better off without us. My only worry is human-built machines spreading our way of thinking in our stead.

I would hope by the time we get interstellar, we would have a different mindset. But you're right. Knowing humans we would strip mine most planets and kill all life that gets in the way.

If petroleum ends up functionally depleted and it cannot be extracted from our cycle's detritus, it's more likely to be millions of years. Likely we will never leave this rock again.
