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.

if clearly motivated people don’t want to vote for you, it’s not an indication that they should lower their standards, it’s an indication that you should have standards to begin with

it’s cute how liberals here are so resilient to reality. people don’t care for slow, steady, painfully incremental progress (if even that) when every summer is so much hotter than the last one.

There hasn't even been slow progress for anything but shifting right. We have been losing everything from the new deal.

It's literally their equivalent of trickle down economics. SOMEDAY IT WILL HAPPEN DESPITE ALL EVIDENCE SHOWING OTHERWISE
