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 post Industrial Revolution is the teensiest-tiniest microscopic doesn’t-even-register slice of time on the scale of the entire time this planet has had a climate.

Then why does the start of the industrial revolution coincide with the exponential increase in Co2 concentration in the atmosphere? Do you think it just came from nothing?

Just because there's a lot of politics doesn't mean we didn't cause it. Yes, the earth has cycles but this is being caused by greenhouse gasses and those gasses had to come from somewhere.
