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 might be closer to changing course on climate change than we realized | Greenhouse gas emissions might have already peaked. Now they need to fall — fast. (www.vox.com)

It's too late to have no identifiable impact, but absolutely not too late to stabilize temperatures — every 1/10 of a degree matters, and it's better that we do it now than wait until we've burned every last bit of coal, oil, and gas.

For sure! It's just frustrating how long this has been a known issue.

More of the CO2 currently in the atmosphere has been put there since it was a known issue.

Depressing but a bad situation is better than a terrible one, so we must push on.
