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.

Don't forget also that meat products need to be fed calories before you get calories back from them. Look up trophic levels if you want more info, but I believe the rule of thumb is 10x the amount of calories needed for most meat products.

It's amazing how much food you have to eat when you're a vegetarian. I went vegetarian for about a year. After my first month I felt like I was dying. Simple things like putting on my shoes left me exhausted. I finally started using a calorie calculator and discovered I was getting about a thousand less calories per day than I actually needed.

I was a banker mason for 10 years before going back to university, carving stone almost every day for years, I went vegan 5 years in and I didn't experience a sudden drop in energy, I made sure I was getting enough protein and adequate amounts of vitamins (especially b12) either through food groups of vitamins tablets.

Also after not eating beef I haven't lost any muscle mass, I may be crazy but I think big beef has been lying for decades.

The difference is that you were wise enough to track your calories and macros after the switch.

That's exactly what my ex-wife said.
