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.

"It is difficult to get a man to understand something, when his salary depends on his not understanding it." - Upton Sinclair

The myth of the humble farmer or small holder living in harmony with his land is as bullshit as the myth of the noble savage. The vast majority of farmers see the planet as a resource to make money from. If they take any heed to local conditions, they think of it in tragedy of the commons style. For instance, in many places around the world, the aquifers irrigating farmland have less than 20 years before they're emptied. Local farmers are aware. They take it as a warning to pump as much water as possible as fast as they can, because if they don't take the water and turn it into profit, someone else will, and the water will still be gone.

And that's not even getting into how these brutal exploitative farming methods are what allowed the Earth's population to balloon to a unsustainable 8 billion and ravage the land and devour resources of every sort.

The vast majority of farmers are the enemy of the planet. In my more green authoritarian moments, I envision nationalizing every acre and setting up eco villages of subsistence farmers populated by the poor of our cities and worked by former corporate middle management reduced to serfdom. No one should own whole square miles of farmland. Not even farmers.
