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.

2nd reply, because when I wrote my first one, your reply was just the first line.

For instance, the idea that early humanoids took the form of “cavemen” who ate a ton of meat is debated, and largely built on assumptions made from finding hunting tools.

I think they were highly seasonal. You had periods where you could gather a lot fruit and plants to eat, your hunting season and your "bare" season where you had to rely on surpluse and preservation. Diet would be highly variable depending on where and when and what resources and technologies were availbible.

The amount of meat eaten in the USA today is not historically common.

Not on average, for sure. But as I said in my first replies, there are examples of early communities that lived almost entirly of meat. Not even a side of fries.
