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.

Eating an animal is always going to be less efficient, because the animal has to eat food to live an most of that food energy will be used up day-to-day rather than staying in its meat.

Also, eating an animal requires that animal to be dead just for your pleasure. No way to get around that either - it will always be more cruel to eat meat than not.

I did read the article and it's good that extra regulation could be used to make the packaging more truthful, but you can't get away from these two claims. (also I happen to know someone who works in a meat packaging plant, and yeah... you can put whatever claims you want on the package and still corners get cut and animals are left suffering because money is the real objective for all companies under capitalism, not animal welfare)

The bigger the animal the less efficient too, since there's more time needed for them to grow and they're using more energy the entire time they're growing since they're bigger.
