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.

The Green Party. But nah, apparently republican democracy doesn't work like that. Winners take all.

First-past-the-post does not. Let's look at three scenarios:

Scenario 1:

Democrat: 10 votes

Repbulican: 9 votes

Green: 0 votes

Democrat wins


Scenario 2:

Democrat: 9 votes

Repbulican: 9 votes

Green: 1 vote

Tied election, decided by a coin toss


Scenario 3:

Democrat: 8 votes

Repbulican: 9 votes

Green: 2 votes

Republican wins outright


This spoiler effect is well-known, and why for any first-past-the-post election, it's worth voting for the candidate with a large coalition who is closest to your position, rather than a tiny third party. You even see Republicans funding the US green party in order to damage Democrats.
