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.

and yet, we STILL won't stop eating animals.

Just switching from beef to chicken and pig gets you 90% of the way to vegan, emissions-wise.

It's an easy substitution to make. Make beef a treat or a once in a while thing.

It's expensive anyway.

Honestly that’s kinda how I treat beef nowadays, and I’m a relatively well-off software engineer. Not to mention, there are real and meaningful health considerations to take into account.

mmmm so juicy

yes...because me eating meat is the highest cause of greenhouse gasses. totally not the unmonitored industrial factories across the globe.

It's not the only source, or even a majority, but it is big enough to matter and it saves money for almost everybody to stop. (Sole real exception: arctic populations who have to import anything agricultural)

it's one of the best things you can do as an individual, among others.

Consequences are coming regardless. Most people are going to keep living their lives as best they can.

Unless industry is brought to heel, we could reduce our footprint to 0 and still be totally fucked.

The lifestock industry alone is responsible for 15% to 20% of the greenhouse emissions, so wiping it out would make huge impact on it's own. Even if you forbade just cattle it would reduce 10% of global emissions.

I stopped eating meat. I still eat cheese and eggs but i'm happy I finally gave it up. It's been a little over a month and I really don't miss it.
