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 report looked at “major,” “severe,” and “extreme” scenarios. The authors found that the “major” case would cost the world $3 trillion over a five-year period, which they estimated has a 2.3% chance of happening per year. Over a 30-year period, those odds equate to about a 50% probability of occurrence — assuming the risks are not increasing each year, which they are.

That's one of the reasons I wanted to be sure we have an area for a garden at our house. I'd like to be as self sufficient as possible, so that we're less impacted by all of the shortages we've seen over the last few years. The shortages will become more common in the future.

Solid thinking. But how big a garden does a family need? And will you always be allowed enough water for it?

My lawn is pretty much gone after the drought we've had for a couple years now. Not sure I'm going to re-plant grass if this is the new normal. And not sure how to know what the new normal is.

I'm in the PNW, and we're on a well, so water is no issue. We'd definitely need a larger garden than we're willing to maintain to be completely self-sufficient, but we can heavily subsidize our fruits and veggies with not a lot of work. My best friend has an area in his backyard that is about 25 feet, by 10 feet, and almost all of his vegetables come from his garden. His parents live on a couple acres and have a garden twice that size, and they're completely self-sufficient, with a bunch of excess. They also have some fruit trees though, about 10 orange trees, some lemon trees, and various other fruits.

I've been looking into hunting too, to harvest my own meat. I've tried being a vegetarian, and I hated it. But I also hate contributing to the industrial meat complex. I figured that if I'm going to continue eating meat, I need to be willing to do what's necessary to harvest it. My wife isn't really on-board with that idea though, so it's something I'm slowly trying to convince her to agree to. Once she does then I'm going to try deer hunting. I figure 1 deer probably has enough meat to last the two of us for the whole year, or most of the year.

Typing all of this out is making me feel like some sort of doomer/prepper. I don't think I'm those things, I just like the idea of being as self-sufficient as possible, and getting our own quality, organic food. I'd raise chickens too if we could, but our HOA says no chickens. I did see a chicken coupe in a neighbor's backyard, so maybe we can get away with it. We're new to this neighborhood, so I'll feel it out first.
