Climate - truthful information about climate, related activism and politics.

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.

Coffee and chocolate are not substitutes for animal meat though. If you look at the chart and compare animal proteins to substitutes like tofu, beans, peas, and nuts the plant based options win every time.

You came so close to the answer, and then fell away. Factory farming as a process is what jacks up those numbers dramatically, not the thing that's being farmed. A few large corporations have seized the cattle and chicken industries, so their numbers would be far lower if regulations reversed that horrific trend (with a few caveats regarding methane in cattle, but I'm trying to stick to the topic). Remember how I mentioned "leaves out a lot of important variables"? That's another of them. Nobody cares that Tyson collects a feed subsidy that's paid for by small-scale farmers, or that small-scale farmers' animal products are 100% environmentally sustainable in most countries. There's nothing inherent about animal agriculture that means it NEEDS to be factory-farmed, or that we need to penalize small farmers so we can kick money over to Purdue.

But even in the current graph, poultry, pork, and seafood are in the same realm as most crops and are dramatically more usable calories. Several things that are not on the chart (wild-caught seafood, animals raised with certain processes, the influence of the symbiotic relationship between animals and crops) put most animals comfortably in with plants.

As for beef, that would deserve it's own entire conversation because those numbers misrepresent a lot of the reality. But that's another topic and I'm starting to tire of having 10+ people reply to me every hour on this topic, most of whom are angry at or belittling me (not you, just in general)
