Climate - truthful information about climate, related activism and politics.

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.

How many seconds of emissions did it take to make this machine?

Edit: I see the other conversation about this. A tiny net benefit is good, but this technology feels like a bandage on a cracked dam. It kinda helps, but people might think it's fixed and there's no more obligation to keep thinking of it.

The messaging that needs to happen is this: we need to reduce emissions drastically on a scale never before seen AND we need to fund research on extracting as much CO2 from the air as possible or we are looking at this being the worst mass extinction in Earth's 4.5 billion year history and that includes the great dying. It is not enough to focus on Carbon capture OR CO2 emissions reduction. We need both and we need them now.
