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.

This is somewhat of a fallacy.

The body of knowledge, collectively referred to as science (not the scientific method itself), should indeed the testable. However, one cannot possibly have the time required in their lifetime to test the entire corpus. At some point you need to defer to experts in most fields.

I'm a geophysicist. I cannot even test the body of knowledge within my own field -- it is far too large. But from my own background and abilities, I can usually tell if something is legitimate or snake oil fairly quickly within the body of knowledge of my own field. I have to assume that fields outside of mine are going the same. If I don't, I become a crazy person.
