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.

Biden just set a new climate goal. Trump and other obstacles await | the United States would aim to cut its greenhouse gas emissions by between 61 and 66 percent by 2035 compared with 2005 levels. (wapo.st)

Does any measures implemented now have any teeth whatsoever? Trump can repel them all in one swoop right?

This doesn't have measures; it's designed to create a situation where other countries are inclined to penalize the US for not meeting this goal.

Which countries ever had the balls to penalize the US? Does that ever happen?

The EU and China have both done it repeatedly when it makes sense for them.
