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.

Given what we know about the limits of soil seqeustration this is basically a PR exercise by the meat industry to keep the methane flowing into the atmosphere.

Yeah, ruminants take huge amounts of grains and legumes to produce small amounts of food. The US basically grows food for cattle and cars, with a tiny chunk going to people.

even better – ruminants are not meant to survive on grains and legumes, it fucks over their digestive system so we have to throw in massive doses of antibiotics to counter the damage …

Any source on the feed being the factor necessitating the antibiotics? Afaik, there just are way too many and they tend to stand in their own shit all day and that makes the antibiotics necessary.

(Somewhat related: I was a bit horrified recently when my dad told me about growing up on a farm and how badly their cattle took suddenly switching from their winter feed [siloed grass] to their summer feed [fresh grass]. When they would become overly gassy after the switch, his granddad would routinely pierce their rumen to let the gas out, along with a bit of blood. This procedure turned out to be completely unnecessary when they started mixing the feed for a few weeks in spring.)

This counts for very little, but I once transported a dairy farmer (Paramedic) between hospitals and had about an hour or so to pick his brain about the industry. As I recall, Corn has too much sugar in it, and if you give your cows too much corn, your feed will be too 'hot' and it fucks the cows up somehow. There's a LOT of work that goes into balancing the nutrient intake for dairy cows. Also, the antibiotics are used for promoting growth in meat cattle, because something about the antibiotics makes the cows grow bigger faster.
