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.

2 centuries ago we didn't have millions of cars on the roads burning gasoline stuck at red lights in gridlocked traffic. Try again.

And yet 2 centuries ago some people were already thinking, exactly like you, that there was too many humans for the earth to sustain them. You can see how wrong he was. The fact that you refuse to learn from past mistakes is quite telling though.

2 centuries ago there weren't anywhere near 8 billion people. Earth ain't got any bigger since then. At what point would you consider the world overpopulated? 10 billion? 15? 20?

I don't see that he was wrong at all, he was just calling it out earlier than anyone was ready to listen.

You might as well warn about the sun eating the earth and turning it into hell. It's not too soon, only 5 billion years left.
