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.

Just of the top of my head here are some possible ideas to explain why not:

  • Meat subsidies
  • Meat substitutes require more processing and additional ingredients
  • Meat sells a lot more than meat substitutes hence the whole chain benefits more from economies of scale
  • Animals raised for meat can extract nutrition from plants and parts of plants which humans cannot (for example cattle can actually break up the fiber in food and extract nutrition from it, which humans cannot), plus they can eat plants which are far more hardy than most plants grown for human consumption. Some will also eat other animals which humans do not, such as insects.

I doubt it's just one of those things that is responsible and suspect it's a mix of those and maybe more.
