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.

It worked perfectly but the purpose is not what you think it is. This facility in Alberta captures Carbon produced by the Scotford Complex, a Petrol Oil Refinery. It was never, ever, going to reduce CO2 in the atmosphere, it was just going to make the adjacent facility produce slightly less. The problem is, of course, that the Hydrogen being used in operations is from a source that puts off more greenhouse gasses than the facility can sequester. We do have the technology to produce Hydrogen more cleanly, but clearly that isn't in the budget.

Why would we trust the people who are putting us in this mess to put us out of it? It's stupid. Confiscate their profit and fund clean energy research with that money

I'm not trusting them to do anything, I'm explaining how the facility works. We can understand things without advocating for them and vice versa.
