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.

Insufficiently ruinous Eco terrorism

Where is Captain Planet when we need him?

If you ever want to feel disgusted head over to Google Earth and check out Midland, Texas. Every square you see is an oil pad.

All must be sacrificed to the parasite class's cult of Big Number Always Goes Up.

Because you can fool some of the people all of the time, and all of the people some of the time ... and they've been at it for a very long time.

They don't need to invest in new production any more, so that capital investment money is now pure profit.

[–] silence7@slrpnk.net 11 points 4 months ago

Sadly, they are in fact investing in new production.

I blame the young earth creationist christians who think that humans are incapable of destroying gods creation, and that the increasing planetary instability means that god will return and put them in charge any day now.

[–] futatorius@lemm.ee 1 points 4 months ago (1 children)

I blame them too, but bigger blame adheres to those who own the fossil-fuel companies, and to the politicians who let the fissil-fuel owners buy them off.

[–] alienghic@slrpnk.net 1 points 4 months ago

There's some weird links between american christianity and oil. At the very least a bunch of the people who got rich off of oil also tended to be devout christians, and used their money to support evangelizing christianity and oil dominance.

There's a number of different reviews for "Anointed With Oil: How Christianity and Crude Made Modern America"

This is an especially detailed one. https://www.bostonreview.net/articles/kim-phillips-fein-anointed-oil/

I found the book and it's reviews after noticing just how biased toward the republicans the owners of the oil companies tended to be. Other large businesses tend to play both sides in politics, but the owners of the oil companies really seem to be really into the traditional gender hierarchies.

It’s way more than cars. Plastics, chemicals, energy, shipping, fertilizers, pesticides, even food additives can trace their ingredients to oil and gas. We’ve structured our whole society around oil since World War I, and getting out of it isn’t going to be easy.

[–] MrMakabar@slrpnk.net 1 points 4 months ago

A lot of it, is due to having waste products from refining crude oil, which could be turned into something usefull. So when you transition away from combustion engine cars, you increase the costs of other oil based products.

[–] futatorius@lemm.ee 1 points 4 months ago

The reason those products were adopted was because the raw materials were available chaply as by products of fossil-fuel production. We'll have to substitute, and will still use some petroleum to produce feedstock for a while. But substitution, efficiency improvements and replacement are normal parts of a working economy. As fossil-fuel derivatives become more costly, we'll ditch them.

Shipping is a separate problem: the logistics and transport sector will be slower to decarbonize because of the long lifetimes of its capital goods.

[–] silence7@slrpnk.net 8 points 4 months ago (1 children)

We're still using fossil fuels, and not phasing out as fast as possible.

[–] SuckMyWang@lemmy.world 1 points 4 months ago (1 children)

Doing it as fast as possible would crash the world economy because everything is setup up for oil. So it seems obvious what needs to happen, it’s a different story when you personally are now homeless and you just want a roof and food. We can do a lot better than we are though

[–] NocturnalMorning@lemmy.world 3 points 4 months ago* (last edited 4 months ago) (1 children)

The alternative, parts of the world will be uninhabitable. Always gotta think about the economy... no matter how many people this is going to kill, or how much biodiversity we lose along the way.

Is there any point of loss where we will say the economy isn't important anymore, or do we have to be experiencing the loss already?

[–] SuckMyWang@lemmy.world -1 points 4 months ago (1 children)

The problem is crashing the economy will kill a lot of people right now, no need to wait or come up with a better solution

[–] futatorius@lemm.ee 1 points 4 months ago

If you look at it on a case-by-case basis, it's harder to catastrophize. Would the world economy collapse if petroleum-derived food additives vanished? No. Plastic bags? No. The vast volumes of cheap plastic packaging? No. Shipping? That'll take a while. Fertilizers? Partial substitution can happen immediately, but a full changeover will take years. And so on through the list. You can rack and stack each case by its social value, how hard it will be to eliminate or replace, and the lead time needed to transition. Beyond that it's engineering, planning and politics.

Chinese power generation has produced more CO2 this year than ever before. They're also bringing renewables online, but electricity usage has risen too. So we're closer to turning the corner, but haven't done so yet.

[–] arin@lemmy.world 1 points 4 months ago

https://youtu.be/zZ-lMDtiI-k?si=gAf8unl2IqUJXNBR USA and China both emit insane amounts of co2 but the population difference...

[–] MrMakabar@slrpnk.net 2 points 4 months ago

We see a bunch of things happening. First of all the West attacked and keeps attacking Russias oil production and exports with sanctions, due to Russias invasion of Ukraine. That means we actually have one of the biggest oil producers and exporters being taken out of the game. Something similar happened with Venezuela and Iran previously. So we actually see declines, just not choose by the countries themself, but mainly by the US, to keep out competition. At the same time 2023 oil consumption is 1.7% above 2019 oil consumption. The pandemic had a massiv effect on the industry and a lot of production is being restarted. However we also see EVs starting to have an impact. There are also a lot of other pushes mainly by net oil importers to reduce oil consumption. This seems to start to actually hurt the industry.

If I had to guess, we probably see the next reduction in oil production in the Middle East. Not due to the governments wanting to produce less oil, but due to a war in the region.

[–] PumpkinSkink@lemmy.world 2 points 4 months ago

Andres Malm suggests in his book "Fossil Capital" that part of the reason that fossil fuels (stocks of energy) are so profitable is that you can pick and choose when to extract and then again when to release the energy stored in them, which will always be more profitable than, for instance, wind and solar (flows of energy) because you can manipulate production to prevent over supply, and choose when to release energy instead of waiting for the energy to be available in the flow. The higher capability to profit means that they will remain more profitable than renewables long after any other sort of calculation other than "profitability" would favor the renewables (cost to produce, damage to the environment, ability to satisfy energy demand).
