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.

Totally. But it can and probably will be used as an excuse for why it's ok to pollute land an air with open goldmines so some company can make gold turd sculptures for rich people to place in their homes as a "conversation piece".

When in reality we should be discussing whether some non-essential industries should get to emit anything at all.

That's what the greenwashing mentioned by the person you replied to means. It's the practice of marketing away the downsides of a product that really shouldn't be possible to rub off. Some things are just inherently wasteful and "offsetting" the waste just means something unavoidable is offset a little less.
