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.

We did it ! We Terraformed a planet ! Earth, a planet that was exactly as perfect as it gets for us to live on it, we Terraformed it into a suffocating hell.

[–] Madison420@lemmy.world 31 points 1 week ago (3 children)

Technically we deterraformed Earth. Terraforming implies we're making it more earth like when we're doing the opposite.

[–] morto@piefed.social 18 points 1 week ago (3 children)

Can earth become less earth-like? I'd argue that we're changing the comparison standard so that more planets become more earth-like

[–] VieuxQueb@lemmy.ca 10 points 1 week ago

So we are terraforming many planets without even setting foot on them, what an accomplishment!

[–] Madison420@lemmy.world 3 points 1 week ago

The main attributes of this planet are skewing away from habitability not towards it.

[–] CapuccinoCoretto@lemmy.world 3 points 1 week ago

Technically Earth is always exactly like Earth.

[–] hanrahan@slrpnk.net 3 points 1 week ago

well, getting rid of the majority of humans will make it better for everything else, so there is that.

that we're doing it to ourselves is gob smackingly stupid.

[–] EggInDisguise@lemmy.blahaj.zone 27 points 1 week ago

WOO! IN YOUR FACE, CYANOBACTERIA OF 2 BILLION YEARS AGO! WE DID IT IN RECORD TIME!

(2ish BYA cyanobacteria in the ocean produced oxygen, but nothing had yet developed protection from oxidation, thus killing almost everything living)

[–] Auli@lemmy.ca 3 points 1 week ago

So that's how they get their religious thing.

[–] Absolute_Slayer@lemmy.world 2 points 1 week ago* (last edited 1 week ago) (1 children)

Just wait a few years, and soon we'll see a hive colonies everywhere.

[–] synapse1278@lemmy.world 3 points 1 week ago

Imagine the futur, with underground cities sprawling deep under the surface, people living to mine the rare earth in devotion for the saint GPU !

[–] zr0@lemmy.dbzer0.com 0 points 1 week ago

Change has an effect in both ways, positive and negative, and unfortunately we tend to focus only on the negative.

[–] pumpupthejam@piefed.social 34 points 1 week ago (1 children)

We're fucked. Glad I'm on the older side, don't have kids, and got to experience this world before we utterly fucked it.

It's true - it was beautiful before The Great Burn.

[–] Malyca@lemmy.zip 12 points 1 week ago

I feel so guilty for having my kids

[–] Confused_Emus@lemmy.dbzer0.com 24 points 1 week ago

I sweat with minimal exertion - combination of a sedentary lifestyle plus SSRIs fucking with body temp regulation. Always thought I might be comfy in the arctic circle. So much for that, I guess.

[–] homesweethomeMrL@lemmy.world 22 points 1 week ago (1 children)

SciAm unable to call out Big Oil.

[–] silence7@slrpnk.net 13 points 1 week ago (1 children)

They were just sold, and fired a lot of the better writers

[–] homesweethomeMrL@lemmy.world 7 points 1 week ago (1 children)

That would explain it. Sold to which billionaire?

[–] livligkinkajou@slrpnk.net 2 points 1 week ago

Scientific American was sold to LabX Media Group, which also acquired Discover magazine in 2024.

Layoffs were expected:

From Jeremy Barr @jeremymbarr
New: Employees at Scientific American magazine were told this morning that their publication is being sold to LabX Media Group.

There will be layoffs as part of that process, according to a memo sent to staffers: "As part of that transition, LabX has evaluated the organizational structure it believes is necessary to support the business going forward. Unfortunately, this means that not all current employees will be transitioning to the new company."

"It's not been a decision that's taken lightly, and it wasn't certainly an easy decision," a member of the Springer Nature management board (existing parent company) told employees in a meeting this morning.

SciAm staff tried to unionized in April with WGAE (Writers Guild of America East), but it seems that in the end, 15 staff were cut out of around 40, and union busting measures were taken by the new owners

As far as I was able to find, Bob Kafato and Ken Piech are listed as founders. Besides that, a quick search did not come up with too much information on their networth, unfortunately

In addition to LabX, the group includes Lab Manager, The Scientist, Technology Networks, Drug Discovery News, IFLScience, Discover and now Scientific American as far as I could find.

To put that in perspective, these temperatures are on par for Orlando, Fla., at this time of year.

If you ever hear the phrase “on par with Orlando, FL” then you know shits fucked. Context is irrelevant

[–] boobookittyfrick@lemmy.zip 16 points 1 week ago (3 children)

This summer has been ominous as fuck. Anytime I’ve pointed it out most people don’t realize what I mean… If you’re in tune with the natural system of weather you recognize a shift like this. It’s been getting slowly worse over the last few years… but this year has been really really different. We are so fucked.

[–] GlendatheGayWitch@lemmy.world 9 points 1 week ago

Not to mention how few bugs there are anymore. You dont even have to clean off your windshield after an 8 hour drive anymore

[–] quarkquasar@lemmy.world 8 points 1 week ago (1 children)

I've lived in the same place for almost 40 years, and I remember the weather around here (Midwest) as a kid.

Shits fucked. And older people are like whatever.

[–] Jumi@lemmy.world 5 points 1 week ago* (last edited 1 week ago)

My place is usually prettey mildly temperatured, not too hot and not too cold, but this years it was unbearable and sometimes the hottest place in Europe. Shit's fucked beyond saving

[–] BarneyPiccolo@lemmy.today 5 points 1 week ago (2 children)

I grew up in Cleveland, and not once in my entire life did we ever have problems with CANADIAN wild fires. It's all wet up there, I didn't think anything could burn. Now it's a regular thing.

That's not normal.

[–] boobookittyfrick@lemmy.zip 5 points 1 week ago

Yeah we’ve been having dust storms like abnormal ones. We barely will get them and this year we’ve had multiple it’s been dusty all week. It makes me irrationally pissed off… except it’s not all that irrational. Fuck anyone who has a part in all of this.

[–] SlippiHUD@slrpnk.net 2 points 1 week ago

Imagine how I feel in mother fucking Cincinnati.

The speed in which the talking point became "Everything has always been like this" to conservatives is mindboggling.

Except our oligarch overlords and their shareholders.

[–] Trampampoline@sh.itjust.works 10 points 1 week ago (1 children)

Oh no, they concur. They decided their greed is worth everyon'e collective suffering.

Every day we do nothing is letting them continue it.

The rich decided to ignore clikmate change and sabotage climate research long before any of us were born.

They knew about this shit in the 1800s.

[–] explodicle@sh.itjust.works 2 points 1 week ago

I wish. Imagine how nice things would be if everybody was smart and sane.

[–] dasrael@lemmy.zip 9 points 1 week ago

The amount of carbon and methane sequestered in the arctic is staggering....and when it heats up, that's going to start off gassing...

[–] Bluedragon012@lemmy.world 4 points 1 week ago

And then Earth ran a fever to try to get rid of the parasites. The parasites will have to adapt to survive, though, some were already changing to a less aggressive bleeding of the earth, in hopes that they will go out saying, "I bit the least!" before starving to death.

[–] altphoto@lemmy.today 3 points 1 week ago

Beachfront property.... Here we go! You, know, plus sunamis and terrible weather.

[–] BillCheddar@lemmy.world 2 points 1 week ago (1 children)

I just need to know how bad, how fast.

Mostly because I miss cigarettes and if I don't need to have quit, I would like them back thanks.

[–] Promethiel@lemmy.world 5 points 1 week ago

Depends on if we're talking peacefully buying them at the shop, or bartering for them in the ruins of civilization. It's hard to tell for sure because there's a bit of a multiplier effect in play when the Arctic seafloor starts heating up.

Also by no means is the Arctic the only big "threshold" around the corner.

If you ask me again tomorrow morning, maybe I'd have a more hopeful answer or platitude ready.

But this late at night? Smoke 'em if you got them. I personally already "un-quit".

[–] Greyghoster@aussie.zone 1 points 1 week ago

We live in interesting times. I didn’t expect it in my lifetime and was worried for my grandkids. Now I expect that we all will see a lot of disasters brought to us by burning fossil fuels.
