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.

No shit. American Petroleum Institute, Heritage Foundation, and others have tried pushing this disinformation for years. May these people pay for their crimes to humanity.

Humanity will suffer far less consequences than many other inhabitants of the Earth.

CO2 has never been a bottleneck for plant growth. It's always been bioavailable nitrogen. This has nothing to do with climate science. If you got this wrong it's because you're a gullible fool.

Wow you think? What, do you do this to animals too? Throw them in double the oxygen and expect everything to work out?

Did CO2 come up with that idea??

No, just those interested in avoiding paying for the externalities from their actions.

These studies are the reason we are in this problem. Looking at one variable, in isolation if all other, and giving oil barons propaganda to tell the masses. Guess those tobacco advisors hired by oil companies did/are doing their job well.

Lying to masses should be punishable in theory

What made them think CO~2~ was the limiting factor?

TIL any models (still) used this bs.
Wtf.
Dirty money everywhere.

Oh great! I can't wait for carbon dioxide induced blood acidity!
