I just wish people would stop acting like I am a “Doomer” over this shit.
Every year its record high summers and winters, tnado alley is moving, rain patterns are all fucked up, I am not even a professional and I can tell the extreme weather shifts from climate change are happening.
I’ve tried having this same conversation with my mum multiple times and she keeps saying that there has been no meaningful increase in temperatures in her lifetime and I’m just thinking what are you talking about?! I just don’t understand what they stand to lose by admitting that humans have demonstrably increased the global temperatures.
Some level of personal guilt for continuing to exist in a system where fossil fuels are burned on their behalf and we often need to burn them ourselves to live a nornal life because the alternatives may barely exist. For example see DEI bike lanes in the states and the banning of them in ontario in canada thus promoting more car use and discourage/making it more dangerous to bike.
My government will do nothing until most politicians dies in not one but multiple tornadoes hitting the parliament… in the same year…
And then they would invest in better healthcare plans, and better security
*for the MPs
Kids today just love to complain about the weather. It was hot when i was young too and the rain didn’t stop us. Tornados have always happened outside their traditional range occasionally. If CO2 is to blame then volcanos are the real problem. /s
People who call you a doomer over this are just those who want to keep their head in the sand.
I’m sure it has nothing to do with the billionaire pedophiles not giving a fuck.
Of course not. It’s not enough people recycling their grocery bags.
Not to say you shouldn’t recycle.
Of course not. But it does feel a little silly when there are town-sized data centres being built in every direction and billionaires are just “choosing” to break all laws. Meta’s got gas turbines running to power theirs and they just said they’re gonna do it for another year. Who’s gonna stop ‘em? Everyone is too busy working and trying to survive to stop them from pretty literally torching our futures and especially our children’s futures.
Things will need to get pretty bad before we see any kind of justice or change of direction, I fear ☹️
Unfortunately we’ve been duped, a lot of it sadly ends up in landfills.
Yeah, I’ve become something of a refuse-police everywhere I go.
It pisses me off that you can just put whatever in the bin and it gets disappeared and you’ve done a great job caring for the planet.
Most of it is just plain not recyclable. Never was. Some can theoretically be downcycled into expensive ugly park benches that no one wants so no one bothers to do that. Only PET can be “re” cycled, but plenty isn’t.
Billionaires do give a fuck. They just don’t give a fuck about anyone but themselves, and maybe close family/friends to some extent.
If I were to hazard a guess I’d guess billionaires fall into 3 camps regarding climate change. Those that still don’t believe in it or that their will be any consequences. They are probably in the minority of billionaires (I do believe most of them believe climate change is real at this point, but their unbridled greed won’t allow them to admit it in public).
Then you’ve got the billionaires who do believe in climate change split into 2 more camps. Those that are so old that they predict they won’t live long enough to see the large scale consequences effect them, and thus don’t care. Finally, those that are young, but believe they can save themselves, without having to help save the world. Those are the billionaires building underground bunkers and compounds. Planning to ride it out from their private utopias.
But at least we made a bunch of grotesque genocidal pedophiles obscenely wealthy.
The thing that doesn’t get called out enough is that many greenhouse gasses have a lag time before they actually start causing heat. CO2 for example takes about 20 years if I recall correctly. So we are seeing the results of what was emitted years ago… not necessarily the current emissions.
Really? I’ve never heard of this, and I’m a climate scientist… Not saying it’s definitely wrong, but a citation would be good.
Edit: Huh, seems it’s true: https://iopscience.iop.org/article/10.1088/1748-9326/10/3/031001 although that is for large pulses of CO2, I don’t know how that translates into a constant stream of emissions…
How fucked are we?
My intuitive answer is that the collapse of globalised industrial society seems fairly likely (as a result of the end of cheap liquid fuel if nothing else). What that looks like is highly dependent on how we respond - it’s not a climate problem, it’s a social problem.
I don’t think humans are going to go extinct, but a population crash seems likely. And we’re taking out a tonne of other species.
Well greenhouse gases are often described as a blanket and a blanket doesn’t immediately get warm, it take time. I doubt the trickling effect is much different in lag time than sudden pulses, its just gradually increasing the blanket rather than pulling it all on at once. Its still gonna take time for more solar energy to accumulate by bouncing off the trickling in CO2.
In the book plows, plagues, and petroleum, the author uses several factors of humans history to argue that man made climate change was slowly having an impact much before the industrial revolution, which is the common “starting point” for most people and scientists. Althought not as drastic as this sudden increase in fossil fuel burning, they argue that impacts such as deforestion and burning of cropland in early human settlements had a measureable impact on carbon sinks and carbon releases, still enough to start skewing the natural rate of climate change.
I wonder if this have anything to do with moving quickly from “we must all limit our energy consumption” to “we must burn as much energy possible for no real purpose”.
I guess we’ll never know /s
we should ask AI!
Fire up the natural gas generators, this baby isn’t grid tied yet!
Lol natural gas? What, do you like, hate America? We need diesel trucks transporting coal to burn on site
Since it started in the mid 2010s, it’s probably not AI related. That will be an extra addition…
‘Sharp acceleration’ meaning 75% faster warming in the last decade compared to the 40 years previous, and blowing past the 1.5° target in 3-4 years. No speculation was given, but I think it’s likely we’re seeing the limits of oceanic absorption of co2 and heat. The ocean’s latent heat capacity has flattened the curve for more than a century, and it’s very hard to predict when that will run out, but sea surface temperatures spiking all over have been good evidence that we have passed a major tipping point in the last few years.
I’ve read that the models used to predict the rate of change were too optimistic or an assumption about them was too conservative and thus not very realistic. Now we have data showing the models under-predicted the rate of change, so one argument is that we were already on this path since decades ago, we just didn’t model it right.
In any case, we’re all fucked so who gives a shit anyway no?
Is there a name for when we know what the right thing to do is but we keep not doing it?
All of the climate models have adjustable parameters. We are still within the bounds of the worst case scenarios but scientists are always afraid to claim too much. An academic’s reputation is a lot less recoverable than a pop star or politician in the sense that they, and their colleagues, actually take their words and predictions seriously. I don’t want to completely dismiss the effect of lobbying and corruption toward the downplaying of global warming, but making smaller-than-necessary claims is a common sight in most academic fields.
Great Filter.
No way in hell we’re facing an extinction event. Unimaginable human suffering, probably, but humanity will persist.
Isolated pockets in relatively protected areas. Global society won’t survive it. Most of the places we grow food won’t be able to grow food, that’s already accelerating. Ocean acidification kills that food source. Blue ocean event accelerates runaway heating leading to massive hurricane force continental storms. Amoc shuts down and Europe ices over. Humanity may persist but civilization won’t.
Vast current areas become arid but vast areas in Siberia and Canada become arable. Very bad but not extinction for humans. Likely extinction for many species though.
None of that thawed soil will be worth a damn for growing at any scale. Like yeah there will be areas that are more or less hospitable but large scale agriculture will not recover
I’ve often wondered… What if we are way wrong about the level of danger, and ultimately climate change will turn Earth into another Venus, and we only find out once it’s too late?
History has taught that humanity wont stop until it has gone too far.
They also banned sulphur oxide in ship fuel which would have had a cooling effect, that was hiding the full extent of the damage and is slowly dissipating
Won’t be long until we start doing that again on purpose
Good news is cloud seeding is viable? Bad news is we’re probably gonna need it.
How great fixing pollution with more pollution.
🎵 The solution to pollution is…more pollution? 🎵
notice that that sharp increase follows 2 events… AI data Centers and literally everything Trump related.
The acceleration, which becomes visible around 2013 to 2015
The massive AI data centers are too new to have an effect yet.
that only takes out one event. there is still Trump and the rest of the corporate corruption causing pollution
I hate data centers as much as the next guy but usually there is a lag time of several years for climate change to link to its causes. We probably haven’t seen the worse of the climate related impacts for up to date AI use yet.
I’m sure in a few years we will find out they already had a bunch of secret AI data centers already built…
We’re all trying to find who did this
“When after all, it was you and me”.
Turns out, the real treasure is the global catastrophe we made along the way.
And by “we” I mean the ghouls running the world.
Pleased to meet you, hope you’ve guessed my name!
… Capitalism. My name is capitalism.
We have had the technology to completely switch to sustainable energy for at least 20 years, but we haven’t because it wouldn’t be profitable to the capitalist class. This problem isn’t caused by us, it’s caused by them.
Even the billionaire cult conterences shifted from “debunking global warming” to “adapting to global warming”.
Yearly average global mean surface temperature from five data sources, in two versions: (top) unadjusted, (bottom) adjusted for El Niño/Southern Oscillation, volcanism, and solar variation. All are aligned so that the average from 1991 to 2020 equals 0.88°C, to approximate warming since pre-industrial.
I have also detected this by the way it is.
That’s pretty neat!
Sadly we’re now at the “I told you so” phase of global warming and much sooner than expected. Now it’s a case of how bad are things going to get.
We still haven’t even peaked in terms of global emissions per year, let alone meaningfully reduced them. Then even after reducing from the peak, we really need to get to net 0, which seems impossible right now.
I’ve been in spectator mode for a while now once I realized the trend. Act locally, know your neighbors, become as self-sufficient as you can. Not much else you can do that will have actual effect.
That won’t have any effect. That’s precisely what the billionaires will come up with. Sort of individual peasant responsibility. We’ll be the ones on a carbon allowance, collecting plastic bottles while they can just buy their carbon credits and burn even more private jet fuel. Congrats on playing right into it.
Like blaming the guy behind bars for not trying something to get out.
I get it - don’t give in, change the world, and hold those responsible accountable. All great goals. But without a plan to do so and leadership/infrastructure, you’re just as bad as me saying to help oneself first. Maybe worse, since at least I’m doing something instead of victim blaming. If you want to rally the peasants to storm the castle, go ahead, but you aren’t going to do that by blaming peasants who aren’t doing it solo.
I also get your point on shifting responsibility. I was there when recycling and the rest was marketed to us. That doesn’t make recycling or its forgotten sisters reusing and repairing useless. It just shouldn’t end there, and shouldn’t be an excuse for other things we do as if there’s some balancing of credits. So if being more self-sufficient is some playing into their scheme, well, at least it’s less that they can control.
100% with you mate, posting revolutionary hopium on Lemmy isn’t doing anything. We have to affect what we can reasonably touch. It starts with talking to friends and neighbours, and making sure you have some security and certainty first.
Yeah, seriously, the whole thing with generalizations in the face of suggested individual action is just so silly. We all know we need to hold billionaires/corporations accountable for their bullshit, energy subsides for fucking oil need to go away like yesterday, citizens United needs to be overturned by legislation, members of congress taking bribes from plastic and energy companies and making legislative decisions as a result need to straight up go to prison, etc. But wtf is the normal, everyday person actually gonna do about it? Call their representatives that may or may not listen because they’re a partisan hack? Good one.
The cliché of getting involved locally is the correct course of action. It’s not throwing molotovs in DC, it’s getting to know your local farmers and getting food from them instead of shipped around the globe five times at some supermarket owned by a giant corporation. Get more trees planted in your neighborhood. Start some butterfly sanctuaries. Start a movement to ban egregiously wasteful lawns in your municipality. Get a coalition of people who pay attention and can mob city hall if/when the city council tries to pull some bullshit deals about yet another fucking data center. Establish better water conservation with your neighbors. This is what the actual, real, legitimate revolution looks like. It doesn’t start with “AND I TOOK OUT MY GUN AT THE GUBMINT!”, it starts with “My neighbors and I started our own little kinda country. ¯_(ツ)_/¯”
Meanwhile, my workplace just announced RTO, starting next year. It’s a moderately large, 100% white collar office site.
Gotta drive those CO2 numbers up, baby!“Data centers fix this” -billionaires probably
And then AI says the should reduce emissions and they order some engineers to fix that clearly broken model 🙄
Tranlation: Do you remember the level in Super Mario Bros. 3 where the Sun tries to kill you?
This is today.
