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's ok. I'm already terrified.

You should be terrified that reduced cloud-cover due to the removal of sulfer from marine fuels over the last few years has had dramatic impact, increasing global temperatures.

High-enough temperatures impede plant respiration, so no, reducing carbon output alone may not be enough to keep the planet livable in a term short-enough to prevent ourselves and so many other species from going extinct.

Reducing global temperatures directly may be the only way to stay alive long enough for the effects of reduced/net-zero carbon output to ever be seen by living human eyes.

It never well look at all the energy we are wasting in AI and crypto. We want to scorch the earth.

If identifying with the billionaires' desires is your cope, the rest of us are no obligation to respect that.
