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.

Nice shifting of the goal post! At first it's too expensive, now it doesn't have the right density and takes too much time to prepare?

Apart from that, you already get most of your nutrition from plants: https://ourworldindata.org/grapher/calorie-supply-by-food-group

This is not because people don't eat as much meat, but rather because meat is really inefficient in providing energy when it comes down to farm area.

Veganism might not solve all our problems, but it's an easy way of getting rid of a lot of environmental problems. Apart from the direct impacts, we could start regrowing the amazon forest instead of cutting it down even further https://ourworldindata.org/what-has-driven-deforestation-in-the-21st-century

I do agree, that it's - depending on where you live, the USA is really fucked up - not always easy to switch to being vegan, but it's definitely a societal problem, not a technical one.

the goalposts never moved. the volume it would take to equal the same caloric intake would be more expensive and impossible to consume.

ever tried to eat a whole cup of rice in one sitting? you'll throw up. if you're fortunate enough to eat three meals a day you'll be eating 3 cups of rice daily, and that's per person.

in a six person family that's 3 pounds of rice per meal! at $1.77 per 2 pound bag of rice. in a month the 6 person family would consume 90 pounds at $159 in rice alone. include all the other ingredients and it's costly.
