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.

who tf is eating beef in India?

Not nearly as many people as in the US. But between ranching and leaving them in the wild, about 1/3 of all cows in the world are in India. As you might have caught, most of the cows in India are actually used for milk... which is a real problem because the lower tech means they get dramatically less milk per cow than we get in the US. As in, 1/4 as much.

The environmental impact of the Indian cow population is non-trivial, both because of how many cows are not used for food and how inefficient their food processes are with cows. In comparison, the environmental impact of the US cow population is arguably quite trivial. Ditto with the other large beef/milk consumers of the western world like Spain.
