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.

The article pretty clearly is about how we can phase out meat in a more controlled and practical way, it just uses the thought experiment of what happens if it all goes as a starting point.

Obviously the concept of quitting cold tofu (you're welcome, PETA.) overnight is ridiculous, but the article has some interesting insights about what is reasonable and how different countries disproportionately burden the environment.

I found these two bits particularly interesting, from a US-Centric perspective.

It might be easier for the average American, who eats about 220 pounds of red meat and poultry each year, to trade a daily hamburger for a bowl of lentils than for someone in rural sub-Saharan Africa, who eats 10 times less meat, to give up the occasional goat or beef stew for something less nutritious. Such a shift in beef-loving countries also might reduce heart disease and cancer linked to eating a lot of red and processed meat.

Dutkiewicz suggested using guidelines established by the EAT-Lancet Commission, an international group of scientists who have designed a diet intended to give people the nutrients they need without destroying the planet. It consists of roughly 35 pounds of meat per year. Adopting that diet would require a drastic reduction of cows and chickens in countries like the United States, Australia, China, Brazil, and Argentina, and a slight increase in parts of Africa and South Asia.

Getting people to go from 220 lbs of meat per year to 35 is not going to be easy but feels like a lot easier thing to point to for those reluctant to give up meat - 35 lbs feels like thinking of meat as a special occasion dish, not a monster that should be avoided at all costs.

I definitely see the cause of frustration and despair, but I find articles like this one help me in having frank, educated conversations with friends and family.
