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.

Humans survive better than most animals. What do you think the world will look like if not even the apex species will survive?

I'm sure some bacteria and virus will survive the Venus like conditions for a short while

I don't think anyone questions that humans will survive. It's just unlikely that the complex global supply chain that gives us complex tools like microchips etc will survive. And may be massive famine etc after just a few harvest failure, or after the grain can't go down the rivers to the sea any more. Naturally not for the very rich, you can probably buy a bag of rice at a price. It's not survival that's at stake, its civilization and all that.
