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.

IMHO increasing food insecurity across the globe will be one of the major issues driven by climate change. If crops fail repeatedly it is not gonna go well for society.

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.

[–] [email protected] 11 points 11 months ago (2 children)

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.

If you're just starting out, you should consider a food forest. You plant an area with perennial plants at every layer (tree, bush, vine), and with the right setup there's almost no labor involved. Add some chickens and all you need to do is harvest.

It's what I'd do if I had the land

[–] [email protected] 2 points 11 months ago

Thank you! I'll look into this. We finally have a little land after years of working and saving, and I'm looking forward to cultivating it this spring.

Try fishing first before hunting, it's a lot easier and if it makes you too squeamish (gutting, prepping, ect) then it's a lot easier to offload old fishing gear than firearms

Not to mention the barrier to entry is a lot lower

Plus being in the PNW (I am as well) fishing spots are basically everywhere

Not to mention catching some good sized fish are more than a few meals in size and they're pretty common

[–] [email protected] 4 points 11 months ago (1 children)

I'm already a fisherman, although not a very good one. I was a decent fisherman when I was younger, but something changed and I'm not that good at it anymore. I've watched a bunch of videos and read a couple of books, but I still skunk out more often than not. I've been at a spot for hours before, had someone walk up 3 feet from where I'm fishing, catch their limit in half an hour, and take off. I'll continue fishing for another hour and not catch anything. I have no idea what I'm doing wrong. I even bought all new gear, thinking that maybe mine was like old and smelly or something, and it didn't change anything.

[–] [email protected] 2 points 11 months ago (1 children)

As with most endeavours, it helps to do some networking. Get out there at all hours and all conditions (be safe!) checking to see who is out when. Pay special attention to those who seem to catch fish quickly; anyone can catch their limits if they spend 40+ hours a week with wet line.

Try to make the acquaintance of the successful ones and get tips. Some will be secretive, but most are happy to share their knowledge. It quickly becomes apparent that they are mostly doing the same things at the same times.

I used to consider myself a pretty good angler. Then we moved to live at a lake that I had never fished before. I was getting skunked so often that I just assumed the fishing wasn't great. Then I started hanging out with others and learned that my old techniques were useless, except under specific circumstances. I adopted the new techniques and now think that this lake may be one of the best fisheries in the province for subsistence angling.

[–] [email protected] 2 points 11 months ago (1 children)

Yeah, I guess that's what happened to me. I learned to fish in the high Sierra Nevadas, and I'm still pretty good up there. But those techniques don't seem to work in the PNW.

The best fisherman I know says to walk until you can smell the fish. That always seemed nonsensical to me, and I assumed he was trolling me. But last year I was walking along the water's edge and actually smelled fish! So I think he was being truthful. I'll definitely give that a try this spring.

[–] [email protected] 2 points 11 months ago

I've stopped to fish where I can smell fish and been successful, but I always just assumed confirmation bias or pattern seeking was happening. Maybe I'll have to pay more attention!

[–] [email protected] 3 points 11 months ago (1 children)

And will you always be allowed enough water for it?

That's an essential element to consider, and the answer is: locally appropriate plants, compost, mulch, rainwater harvesting, and greywater. All of these things will work regardless of municipal water shortfalls, political problems, etc.

Examples of locally appropriate plants: local so-called "native" perennials, and annuals that are well situated for local conditions. For example, tepary beans are great in desert areas while typical beans from most seed packets are not. And conversely, tepary beans don't fare well outside of a desert. Plants evolved growing without us. Picking the right varieties and then giving them a boost with mulch and greywater gives awesome results.

Very good points.

Every society is three meals away from chaos. I guess that's still valid.

I think I’ve driven past that trailer before. It’s off the 5 freeway in California’s Central Valley. The guy who puts them up is not a climate activist. He’s just very Republican and blames Gavin Newsom and the Democrats for water being expensive in California.

[–] [email protected] 7 points 11 months ago

You're right! I've seen that too. It's near the billboards that say "pray for rain".

Is this comment responding to the wrong thing?

[–] [email protected] 8 points 11 months ago

The thumbnail on the preview card and the header image in the article is what I meant.

[–] ratman150 7 points 11 months ago

The trailer is in the thumbnail.

oh yeah and some folks will die but what can we do about the trillions???!!!

[–] [email protected] 8 points 11 months ago (1 children)

Lack of food and water will lead to war, and the war machine will pump even more carbon into our atmosphere, leading to more drought and less food and water. It's a self-sustaining cycle and I've no idea how we avoid it at this point.

[–] [email protected] 1 points 11 months ago

Good water recycling systems (and desalination systems for those on the coast) combined with low cost and distributed synth bio based food production (i.e. precision fermentation, or biomass fermentation) could help relieve some of the strain on the food and water needs.

Don't worry, the nuclear winter will cancel it out.
