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.

Honestly, the whole concept of "recycling" plastic feels more like a PR strategy than an environmental solution. If it were genuinely effective, we’d see investment, innovation, and accountability—like we do with metals. Instead, we’re handed the guilt while corporations keep pumping out garbage.

Much like the concept of a carbon footprint, it exists solely to make consumers think they can make an individual difference so they won't push for regulations

Yeah I especially love that one everytime I fly. I get to choose the environmentally friendly option with lower carbon footprint for more money. Who the fuck they think they are kidding? We are all in the same plane burning fuel at 10000 m.

Dont forget the goal of disrupting actual leftist movements into confusion

The sad thing is, only types 1 & 2 plastics are recyclable in any real fashion, and sometimes not even then.

That means types 3 through 7 are better disposed of in the trash, where at least they’ll be sealed into a landfill instead of being shipped overseas to end up somewhere far less environmentally secure.

These types are the numbers inside the recycling symbol. Many things are mixed and matched - a plastic bottle might be a type 1 (recyclable), yet its screw-on cap is typically a type 5 (largely non-recyclable). Always try to find the recycling symbol and dispose of anything not a type 1 or 2 in the trash.

[–] ILikeBoobies@lemmy.ca 5 points 6 days ago

I noticed a bottle was recyclable but the label wasn’t, was annoyed that they would do that because I doubt there are many who would read the label to know that

But even recycled plastic just gets shipped to SEA for them to deal with instead of actually being recycled so I guess it doesn’t matter

[–] potpotato@lemmy.world 1 points 6 days ago

#7 isn’t even a material, rather “other.”

PS (#6) and plastic films can be recycled at dedicated drop offs.

[–] Echolynx@lemmy.zip 1 points 6 days ago (1 children)

It depends. My municipality recycling bins take type 5.

[–] rekabis@lemmy.ca 2 points 5 days ago (1 children)

I can absolutely guarantee that it is either

  1. Burned for power generation
  2. Disposed of in a landfill
  3. Exported to a foreign country

Only about 0.5-2% of all “recycled” polypropylene is actually recycled in North America, in places where it is accepted for recycling.

[–] Echolynx@lemmy.zip 2 points 4 days ago

True, fair enough.

Treating waste water? Water treatment plants cost so much that they will never compete with dumping raw sewage into the river!

[–] Blackmist@feddit.uk 6 points 6 days ago

Which is why my local water treatment plant built a brand new pipe so they can dump directly into the river rather than the local nature reserve.

I'm so glad we privatised that...

[–] Aeri@lemmy.world 7 points 6 days ago (1 children)

Honestly if it was up to me I'd just ban plastic flat out unless you got some kind of "this is actually really important and NEEDS to be made of plastic" cert

[–] Echolynx@lemmy.zip 2 points 6 days ago (1 children)

There are tons of single-use plastic medical supplies - syringes, wrappers, etc.

[–] starman2112@sh.itjust.works 1 points 5 days ago (1 children)

Would you say that those things are actually really important and NEED to be made of plastic? I wonder if Aeri would account for that possibility

[–] Aeri@lemmy.world 2 points 5 days ago (1 children)

I'm not the ultimate authority on all things, but I'd question if these things need to be made of plastic.

Syringes are made out of things like Borosilicate glass, Stainless steel, autoclaves and cases exist.

It would also be way less big a deal if we just didn't have as much plastic in general.

[–] Echolynx@lemmy.zip 1 points 4 days ago (1 children)

It would be a lot more costly to make syringes out of glass/steel for single-use types.

[–] Aeri@lemmy.world 2 points 4 days ago* (last edited 4 days ago) (1 children)

Counterpoint, how much is cancer treatment for (research sounds, papers rustling)... Seven thousand people†?

Multiply that by... some studies show costs of cancer treatment as high as $173,831 annually. 1,216,817,000? Would it cost more than 1.2 billion dollars a year to stop making everything out of plastic? This is just like, napkin ass math I'm not pretending to be a huge know it all or anything by the way. Personally I think that yes, we should stop making things out of poison, even if it costs more money.

A recent study estimated that PFAS contamination in drinking water contributes to more than 6,800 cancer cases each year in the United States.

[–] Echolynx@lemmy.zip 1 points 3 days ago

I don't disagree with you at all, but I just don't see a way for it to happen in the current corpo-controlled climate.

[–] max_dryzen@mander.xyz 6 points 6 days ago* (last edited 6 days ago)

Interesting to compare aluminium recycling with plastic recycling

When the true aim is to recycle material, industry comes to the party and you get a refund scheme, even purpose built deposit facilities that can be set up locally

When the aim is to misdirect public attention toward a non solution you get government mandated plastics recycling bins and penalties for "contamination" plus never ending messaging (gotta keep the lie alive with constant repetition lmaooo). Coercion is just a lowkey admission that the material isn't worth recycling

The real question isn't how to get the plastics industry to change, it's how to make the ruse no longer a tenable position for governments

[–] AntelopeRoom@lemm.ee 4 points 5 days ago

Its basically impossible to avoid too. Anything you buy comes packaged in plastic for the most part.

[–] syklemil@discuss.tchncs.de 94 points 1 week ago (6 children)

The price stuff can change through taxation that makes new plastic more expensive than recycled plastic.

As we all know, taxation is super popular and has never been controversial, ever.

At the very least flaskepant has worked great for like a century here in Norway. Always kind of surprising when other countries don't have it.

[–] nickwitha_k@lemmy.sdf.org 3 points 6 days ago

The US still has subsidies going to petrochemical companies, despite being insanely profitable. Basically, just extracting the country's wealth in addition to natural resources. Ending those or forcing them to be spent on recycling would help here immensely.

[–] bingrazer@lemmy.world 33 points 1 week ago (5 children)

Most plastic can’t be recycled into something usable. Plastic degrades quite a bit with each recycling, leaving a bunch of microplastics behind (same thing with “biodegradable” plastic). It would be better to tax it enough (or ban it) to make it not used in certain applications.

Being an old man this really gets me. I love the internet and the way computers today but there is a whole lot that worked fine before plastics were so common. Almost nothing in the grocery store had plastic and everything was pretty much as convenient as nowadays. Sure you had to pay a deposit on the glass bottles but you got it back when you returned them.

[–] derpgon@programming.dev 13 points 6 days ago (2 children)

If I had to choose glass or plastic, I am always choosing glass. Glass is such a good material. It is infinitely recyclable, the bottles can be reused for several years, and if they are buried they don't release microplastics.

[–] HubertManne@piefed.social 6 points 6 days ago (1 children)

I jump for situations where the glass is taken back for wash and reuse. Its the most sensible thing. I swear I had heard about restaurants doing this with containers but I never actually encountered one. So they had perm togo containers they took back and washed.

[–] derpgon@programming.dev 1 points 4 days ago

That's what we have here in Czechia, it is called Rekrabička.

[–] AnyOldName3@lemmy.world 3 points 6 days ago (2 children)

It depends on which aspects of the environmental impact you're looking at, as melting glass to recycle it can be much more damaging than landfilling several plastic bottles if the glass furnace is heated by fossil fuels. If glass bottles are washed and reused, they're much better than plastic, but that's rarely what happens.

[–] derpgon@programming.dev 2 points 4 days ago

Gas is used to heat up glass furnaces most of the time. But it is possible to use elctricity aswell, which is more and more sources from either solar or nuclear.

Not saying it is greener than plastic when it comes to electricity and shipping.

[–] HubertManne@piefed.social 1 points 4 days ago (1 children)

The cleaning was common back then. Every store took back the tall glass bottles of soda and in modern times oberweiss brought that back with milk. The glass melting is nice just as a final option really.

[–] AnyOldName3@lemmy.world 1 points 4 days ago (1 children)

That's reuse, not recycling. Glass is much more suitable for reuse than plastics as it's longer-lasting and can withstand temperatures hot enough and cleaning agents strong enough to ensure it's food-safe after being collected, but you need quite a bit of infrastructure to get the bottles back to the company whose products they're for. At least for the parts of a bottle's life that the manufacturer's responsible for, it can be much cheaper to make fresh plastic, and if they can externalise the environmental cost of disposing of a plastic bottle (i.e. blame the consumer), it can look better for their carbon footprint etc., too.

[–] HubertManne@piefed.social 2 points 4 days ago

yeah I was not limiting my comment to recycling just about how we don't really need to be using plastic everywhere and how things were pretty fine in the 70's where you only saw plastic in a few use cases.

Really annoyed to have believed in plastic recycling even into my thirties. Being an idiot is such a burden sometimes.

Right now it looks like paper and metal recycling is still good as far as I can read in two minutes. If someone has a correction let me know.

[–] JubilantJaguar@lemmy.world 35 points 1 week ago* (last edited 1 week ago) (3 children)

Correct. Paper (PS: or at least brown cardboard), glass and alu will always be great candidates for recycling.

[–] faythofdragons@slrpnk.net 46 points 1 week ago (1 children)

Aluminum is the poster child for recycling, really. It takes more energy to extract it from the ore than it is to recycle it.
