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.

"Still, every little bit helps, as the old woman said when she pissed in the sea."

I wouldn't tell people not to try just because they aren't running data centers. Other people see people trying then it inspires them to try, and seeing a bunch of people trying when others are rolling coal makes people act accordingly.

Would you go to a protest against a data center if the dude asking you didn't give a fuck and it was obvious? What if they were making changes to their lifestyle and trying hard too? It's more inspiring when people actually do what it takes.

But when you're in a culture where people just litter, you don't try because someone who seemingly cares also isn't trying. You don't want to be in a situation where everyone gives up, even those that care.
