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.

Congrats, everyone! We finally did it! And way ahead of schedule! Take that, scientists! They said we couldn’t do it before 2050. They warned us! They scolded us! But look at us now! Eat it, nerds!

sigh

This is fucking ridiculous.

I'm just sad I'll never have another snow filled winter living here

[–] Sam_Bass@lemmy.world 5 points 5 hours ago (1 children)

So about when can we expect the next ice age?

We're in the ice age, it's supposed to be cold right now. So... Around 100,000 years after humanity either dies out or becomes subterranean.

[–] mke@programming.dev 10 points 9 hours ago (1 children)

Don't worry, cheaper solar panels, electric cars and entrepreneurs will save humanity. And by humanity I mean a specific share of the world's developed nations. Discourse on this frustrates me to an unhealthy degree.

If you promote techno-fetishism laden, borderline tech-bro driven or shitass bill gates financed media, please reply so I may wish upon your remaining bloodline an everlasting mildly inconvenient curse.

And if you like Kurzgesagt tech videos, please reply so I may respectfully call you a fucking donkey.

[–] hexabs@lemmy.world 6 points 7 hours ago* (last edited 7 hours ago) (1 children)

What's that about kurzgesagt?

I often found good citations/ research evidence linked to their claims (on climate change)

[–] theonlytruescotsman@sh.itjust.works 3 points 4 hours ago (1 children)

They repeat whatever their donors claim without any checking on their part. Sometimes this lines up with science, sometimes it's just propaganda.

[–] hexabs@lemmy.world 2 points 1 hour ago

Any example videos that are propoganda?

I'd like to scrutinize one so I can fact check better in the future. I mainly check the citations in the links.

[–] msage@programming.dev 9 points 10 hours ago

Bingo!!!

I had this on my 2024 bingo card.

God I hope I'm wrong about 2025 BOE.

[–] phoenixz@lemmy.ca 14 points 11 hours ago (1 children)

And so far, what have we done?

Pretty much nothing. We've done a lot of pretending with "let's recycle plastics", which them just get dumped anyway because fuck you, that's why.

We're slowly slowly moving to electrical cars instead of pushing hard for bicycles and public transportation. Profits over anything else!

We've implemented.next day deliveries, because THAT is important. Fuck your winter

The US just choose a climate change denier who put a guy in charge of the EPA that can't stop talk about pushing businesses and economy and oil.

The world is lead by narcissistic psychopaths and everyone just lets them.

Denmark has officially cancelled winter translated article. I don't like this timeline.

[–] P1nkman@lemmy.world 9 points 13 hours ago

Yes, the line is going up. That's good, right? Shareholders keep telling me that the line must go up, and it looks like we're doing it! Good job, everyone.

[–] Allonzee@lemmy.world 21 points 16 hours ago (1 children)

May our descendants never forgive us.

If there are any.

Don't blame me, I recycled! /s

[–] Allonzee@lemmy.world 6 points 11 hours ago* (last edited 11 hours ago) (2 children)

Our mass cowardice, mine included, is our shame and culpability.

Like the German citizens who weren't Nazis but stayed quiet and didn't protest, only on a global scale. We should all be Greta, getting arrested doing the right thing, but again cowardice in the face of inhumanity is our sin.

Just smart enough to figure out how to blow ourselves up, and still stupid enough to do it.

It always provides context for me in life to remember that, with great difficulty, humanity managed to do something I would think any sapient life form would consider a massive technological threshold/achievement: we figured out how to split the atom, releasing practically limitless energy.

...And Why did we suddenly rush to do so? To make big boomie boom rival monkey tribe.

Yep, even in the nations I often look up to from my gold plated shithole as the last models of humanity on Earth, all the while going back to the same question...

...and being left with the same sad answer, we as a species arent the cure, and we aren't both, we're just the disease.

[–] HandBash@lemmy.world 19 points 19 hours ago (1 children)

Hottest year to date, so far.

[–] Monument@lemmy.sdf.org 49 points 23 hours ago* (last edited 23 hours ago) (1 children)

Big fucked if true.

I looked it up the other day. We crossed 1c in 2015/2016. News stories at the time talked about how 1.5 might happen as early as 2035 if we don’t get our climate act together.
Yikes.

[–] flames5123@lemmy.world 5 points 4 hours ago

With Trump, he’s gonna help get to 2c by 2028…. Mega fucked.

[–] Pizza_Rat@lemmy.world 49 points 1 day ago

We did it guys 🥳

[–] x00z@lemmy.world 39 points 1 day ago (2 children)

I see so many people thinking that this isn't going to be a problem for them because they are thinking of heaters and AC and also that they'll probably die while it's still livable.

But meanwhile they put kids on this world, who will call our generations the worst people to have ever existed.

[–] Tiresia@slrpnk.net 4 points 18 hours ago (4 children)

Despite what capitalism would have you believe, humans are part of nature. With the same effort that has allowed us to destroy nature faster than any other species, we can maintain or restore balance better than any other species. It makes as much sense to argue against the next generation of humans to "restore the ecosystem" as it makes sense to argue against the next generation of bees.

Let them call us, those born in the 20th century, the worst people to have ever existed. It's not far from the truth. But why let that stop us from doing the right thing: giving birth to them so they can fix this mess for future generations or die trying? Why let our shame deny the ecosystem the best chance at recovery?

[–] nossaquesapao 3 points 5 hours ago

With all the respect, Your argument feels just dogmatic. If we can solve the climate crisis, we must do it, not hope for someone else to. All this generational talk feels just like an excuse to keep the status quo. There's no magical generation coming to save the world, just people just like us.

[–] x00z@lemmy.world 4 points 8 hours ago

I'm saying it's extremely selfish to put kids on a world you're not fighting hard enough for because it doesn't concern you.

[–] danciestlobster@lemm.ee 1 points 8 hours ago

This is a genuinely nice sentiment, but it is worth noting that the world is way more populated than most past generations, and while any hope for us will fall largely on the squares of future generations, their job would be so much easier if there were a lot less of them.

Some developed countries seem to have this notion that declining birth rates will be the end of them and while that can be somewhat true for how economic systems are set up, the world was objectively a lot more sustainable before the boomers generation, population wise

[–] starelfsc2@sh.itjust.works 9 points 17 hours ago

Because living in a world with extreme weather events where you can't leave your house for weeks because of heat waves and never before seen storms, and possibly damage to your home(this has already happened where I live), where a home garden will die to heat waves, with constant shortages of food and water, is not a life I'd wish on my enemy, much less someone I love.

We are already starting to see more extreme heat waves and weather, we know it's happening, and we're drilling for more oil than ever, so the chances the next generation will suddenly start making big changes when the past two have done worse than nothing while being fully informed seems extremely unlikely to me. I'm pretty optimistic on most everything, but there is not a single sign pointing to this being resolved by humans within the next 100 years, if ever.

[–] Lennnny@lemmy.world 17 points 1 day ago (1 children)

We at least didn't have kids, and I'll probably accidentally drink myself to death anyway.

[–] frostysauce@lemmy.world 2 points 5 hours ago

Same here. Cheers!

[–] conicalscientist@lemmy.world 26 points 1 day ago (1 children)

Grim milestone and barely a peep about it in popular discourse. Everyone needs to prepare personally for the consequences.

For one thing I'm not expecting food prices to level off for the rest of my life. Everything's just going to get more scarce and expensive. Is it possible common foods we enjoy now we may never have again at some point?

On a lighter note. I got a new winter jacket in 2019. Between covid and the rapid decline of cold winters I've barely worn it.

Human migration is going to get crazy really soon.

[–] HappycamperNZ@lemmy.world 17 points 1 day ago (1 children)

Sitting here in a beautiful sunny day, people can be forgiven for thinking its not a big deal.

Until you realise how much energy it takes to raise the temperature of the ocean and land by 1.5. And then that all that energy goes into every weather event forever until we reverse it.

[–] Reverendender@sh.itjust.works 7 points 1 day ago* (last edited 1 day ago) (1 children)

55 degrees F in Massachusetts a week before Christmas. I was driving with my windows down. I got nuthin else. What the shit, man.

[–] camerondakota@slrpnk.net 3 points 16 hours ago* (last edited 9 hours ago) (1 children)

It’s been twenty degrees F (11C) above average in Arizona this week. Should be frigid with snow on the ground (in the mountains) yet I was riding my bike with a t-shirt this week.

[–] Reverendender@sh.itjust.works 4 points 14 hours ago (1 children)

OK, I looked it up. Average from 1979 to 1999 for me on December 17th was 29.1 degrees F.

[–] HappycamperNZ@lemmy.world 2 points 7 hours ago

Can we have it in non-freedom units, il even take a clothing layer comparison is the metric systemis spawn of Satan. Is this snow - t shirt weather?

[–] Enkers@sh.itjust.works 25 points 1 day ago (2 children)

The shape of that curve scares me. I just hope it's a sigmoid curve, not an exponential.

[–] Reverendender@sh.itjust.works 5 points 14 hours ago

Every collapse seems to trigger 12 others, further compounding things at an insane rate

[–] chonglibloodsport@lemmy.world 20 points 1 day ago (1 children)

True exponentials are rare in nature. Things can look exponential in the short term but are really logistic.

Look at it this way: if the atmosphere gets hot enough it’ll boil off into space and then the earth will cool back down again due to the loss of greenhouse effect.

[–] TheBenCommandments@infosec.pub 1 points 4 hours ago (1 children)

Unless we’re the next Venus

[–] chonglibloodsport@lemmy.world 1 points 3 hours ago

We don’t have the atmospheric pressure to be Venus (92 times the pressure of earth’s atmosphere). There’s simply far more gas there than here!

[–] yessikg@lemmy.blahaj.zone 26 points 1 day ago

Yeah, sadly not a suprise

[–] disguy_ovahea@lemmy.world 17 points 1 day ago* (last edited 1 day ago)

And with it, another group of mitigation advocates become doomsday acceptors in the scientific community.
