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.

We could stop cutting down the fucking rainforest and start planting trees since that’s already engineered by nature.

We could also stop digging up oil from the ground and burning it. Novel idea I know.

Fully grown trees are carbon neutral. Yeah trees are made of carbon and when growing they pull carbon from the air and turn it into wood. Once fully grown that's it.

We should use more wood for construction, that way we clear more land for growing new trees with the wood essentially storing carbon in the structure of a building.

But the impact of that won't be much. We should do it because every little bit counts, but it would only be a minor part of a much larger solution.

Yup. That's the crux of the problem. We're pulling chemicals from the ground and burning it. Were do the gases from that go? Nowhere. They just stay in the atmosphere.

Biochar -- Use highly efficient biochar retort machines to turn clean biomass waste into carbon that will last thousands of years and use it as an amazing soil amendment.
