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.

Cattle don't have any of the survival instincts left, and they have been bred to be docile and overproducers of milk and meat. They would die of starvetion or dehydration with swollen udders and any number of horrific diseases.

That's not to say they are better off in factory farms, but if the question is should we reintroduce them to the wild, I would say no.

There are many breeds of cattle. Some which are on their own for most of the year. I am sure with some carefully selection (and maybe a few generations of crossbreeding) there could be viable breeds for reintroduction to most biomes which historically had wild cows
