The carbon that we dig out of the ground and put in the air, that is the ony one relevant to global warming. Everything else is just a change of phases in a cycle.

Yeah but problem is that the methane phase is a much more powerful greenhouse gas than CO2

CO2 in air » plant » cow » methane in air (cow bacteria farts and burps) » CO2 in air

Also carbon sinks around the globe are being replaced by systems that are at best carbon neutral. Every acre of carbon sequestering rainforest cleared to farm cattle is a net decrease in our ability to process atmospheric carbon.

True, add to that CO2 emission for transporting all that animal feed around the world

Climate - truthful information about climate, related activism and politics.

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.
