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.

I took a quick skim. By toxic atmosphere, they mean as in probable health hazard, not as in directly killing people immediately.

Indoor co2 levels can easily hit 1000+ ppm co2, especially if your dwelling is well sealed, as many energy efficient dwellings are. Submarines keep co2 at the thousands ppm for extended periods and were the impetus for co2 studies on how much humans can take.

I don't think a major concern of rising atmospheric co2 is the direct threat to health caused by elevated co2 levels. I, personally, would be angered if someone told me that high co2 levels were dangerous to human health and then I read this.

Well wie couldn't stop capitalism from killing us and now it's killing is.

Maybe what comes after has a chance to not invent a species killing ideology.

"Son, good job on your science test. Seeing your hard work pay off is like a breath of fresh air."

"Daddy, what is fresh air?"

Fresh air shops already exist. If the need grows, the supply will grow.

If atmospheric CO2 becomes a health risk, I could imagine future buildings having an attached greenhouse that provides a steady supply of fresh air.

According to this source, "Crops grown in controlled environment agriculture (CEA) production systems such as greenhouses and vertical farms in warehouses consume CO2 as they undergo photosynthesis when exposed to light. A typical greenhouse crop will use 4.8-9.6 kg per hour per acre. This process can drop the concentration of CO2 from ambient levels (around 400 ppm) to as low as 100 ppm if the production site is not ventilated."

This means one acre of greenhouse can provide fresh air to about 15-30 people. That same greenhouse could also provide enough food to feed 5-7 people. Extreme weather will make 20th century style industrial agriculture increasingly fragile, so we're going to need to switch to food forests and greenhouses anyway. Hooking those greenhouses up to housing so people can breathe would be a nice synergy.

The kids can decide for themselves, but long before then I choose exit stage left.

Damn. Our current trajectory already would've made life very unpleasant in 100 years, this news moves up the potential extinction part to be far closer than I'd anticipated, which means if we can't cast off capitalism soon, it will destroy our species and most other life on earth very rapidly.

We desperately need to build up decentralized grassroots working class movements globally as quickly as possible, enabling the use of our most powerful weapon: the General Strike.

The governments propping up fossil fuels would be brought to their knees if suddenly deprived of profit and labor, allowing us to demand real changes, such as an end of fossil fuels, the abolishment of centralized state governments, and the end of capitalism.

The general strike was extremely effective in Chile in 2019, and had they not fallen for the trick of liberal reform, they would've had a successful revolution on their hands.

There are some concrete steps all of us can take toward enacting a general strike to make it more viable and bearable for us all. (the titles below expand if you click them).

Learn First Aid! ⛑️

Enacting a general strike will result in violence being used against us even as we attempt to avert global destruction. It extremely important to have the skills to be able to keep yourself and others alive if they get hurt.

Tacticool Girlfriend provides a great introduction to building a personal first aid kit, called an IFAK, which can deal with things like bullet wounds and other serious bleeding wounds. I also want to emphasize her recommendation of only buying medical gear from reputable sources (not Amazon!), such as North American Rescue to avoid fakes that could cost you your life.

But you'll need to learn how to use that equipment, too. The best resource for that is to take a local Stop The Bleed class, which are pretty widely available in most places. They may cost a small fee, but can also sometimes be free. Alternatively, if you cannot access a local class, this video by PrepMedic will give you a solid understanding of how to use Tourniquets and Gauze for wound packing.

Injuries are less harmful if they are tended to early. Learning first aid can help conserve resources when healthcare becomes unaffordable. Having several medics in case of harm by police is an extremely powerful morale booster during a protest that may become a police riot. When you become comfortable with the basics of first aid, riot medicine is the next suggested step.

Establish or join local Mutual Aid networks ✊

If you haven't already, get to know your neighbors. Mutual aid is a willingness to support and grow your community. This can include informal networks through friends, tenant/renter organizations, solidarity groups, and industrial unions.

These are groups using direct action to solve each other's problems. Building strong communities makes it difficult for fascism to take root. The actions of the government are going to hit every community hard, and the ones who build trust in each other and work together are most likely to survive. We've been building a list of resources in !inperson@slrpnk.net to help you on your way. Also check out this handy guide to find existing groups in your area.

This isn't only for your own community protection. Your ability to organize today will change the political landscape tomorrow. When revolution occurs, the social organizations that show the greatest resilience through the regime are the ones typically calling the shots when the dust settles. When it comes to elections, get out the vote drives are useless if most of the voters are fascists. At some point, you have to do grassroots political education if you don't want fascist candidates winning elections. Mutual aid networks are excellent forums not only for teaching each other good political ideas, but demonstrating them in practice.

Join a Union to help prepare for a General Strike! 💪

If you aren't in a union (or even if you are, it's worth dual-carding), consider joining the IWW to unionize your workplace (bonus: you'll get higher wages, better benefits, and more time off if you succeed!). Unions are essential to effectively enacting a general strike, as most unions have a strike fund that can supplement your income during a general strike to make it more financially bearable (you should also save as much money as you can reasonably do, so it can also be used to keep yourself afloat during a strike).

And for our international friends, you should join one as well, as fascism is gaining momentum globally, and they are in bed with fossil fuels. If your country isn't listed below, just contact the IWW directly in the link above, and they'll help you set up a new local branch.

Adopt Security Culture and Digital Camouflage 🛡️

Sometimes benign seeming efforts can turn into unexpected personal data collecting traps. Like an obscure website for exchanging contact info with other students turning into a global ad-tech surveillance network (Facebook), or innocent seeming online personality tests being use to harvest character profiles. Even Etsy, Reddit, Tinder, and Duolingo are feeding information to US Government Agencies like ICE.

Security culture is commonly used to describe the general awareness of such potential traps and how it can affect groups or entire communities. This goes beyond mere individual privacy efforts, as without joint efforts these often fail to work.

Especially in activist circles, security culture is paramount. For opsec reasons not everyone in the group might be aware of what clandestine efforts others are involved in, but with a general security culture many potential data leaks can be avoided.

Movements are made by the volume of their participants, and the easier and less dangerous it is to participate, the more people will get involved. As more people get involved, individual involvement becomes even less dangerous, creating a virtuous cycle.

We'll start it off with some General Advice:

  • Mentally wall off personal uniquely identifying info from your online presence, actively build a habit of opsec so that withholding information is your default mental state
  • Be careful about who you meet online
  • Use different, unrelated usernames, passwords & emails for every account. And try not to connect to those accounts with your real IP address (use Tor or a VPN)
  • Be mindful that anything done online leaves a trail
  • agents provocateurs may seek to find patsies willing to perform an ill-advised illegal activity in order to legitimize police repression. If someone is trying to pressure you, especially if you don't have a long and proven history with them, be extremely wary.

For a full guide on what encrypted communications platforms to use, and how to stay off the radar, read the Digital Camouflage section within the Monthly Meta post here (you'll need to scroll down. I'd add it here, but it won't fit in this comment).

I'd also highly recommend Full Spectrum Resistance to anyone who wants further info on how to resist (audiobook version here).
