There is no ceiling. It might go up 6 or 7C. The people who have the power to change things do not give a shit if the rest of us die. They don't care, and they won't change anything. That's the world we live in.
4C is basically Mad Max breakdown of society. Problem is self-correcting after that.
If there are survivors, they will be the dicks. Nature is heartless and unforgiving. It is truly survival of the fittest.
They (selfishly) believe that allowing the problem to flourish is what will get us to solve it.
They're not wrong. There's just way better, more humane approaches.
So you're mostly right. Because they know they have the wealth to weather the discomfort in comfort. But it is accurate that humans historically are fucking aces at reacting and kinda piss poor at proacting.
Oh, you’re hot? Return to work. Our buildings are kept cool for your convenience! 😈
That’s the next play
uh no florida has already made the next play, and it was to repeal all protections for outdoor workers against the elements
in other words the next move is literally "Fuck you, die", apparently, so, good to know we're past the bullshit and can get on with actually solving the problem properly.
Not really. Economies started to slow down and crash when warming gets over 2°C and CO2 production crashes with it.
Finally some good news on the climate. Our ability to fuck the Earth will mostly go away when our civilization collapses. We might even get a second Genghis Khan cooling when everyone dies.
There is a problem of lag. By the time temperatures are high enough to force the economy to stop, the amount of CO2 will be sufficient to continue pushing the temperature up considerably.
The problem is that feedback loops start to kick in above 2°C so it doesn't matter if the economy crashes.
In fact, in some cases that makes things even worse. One example is that without smokestacks and ships pumping out sulfur dioxide the albedo of the atmosphere will rapidly drop, which might cause immediate and rapid warming over a period of only a few years.
We could be pushed past 2.5°C or even 3°C without industrial forces contributing at all.
I mean they might care when billions of people try migrating in to more northern countries.
As a citizen of one of those "more Northern countries", that is one of the things that concerns me.
"I think we are headed for major societal disruption within the next five years," Gretta Pecl of the University of Tasmania told The Guardian. "[Authorities] will be overwhelmed by extreme event after extreme event, food production will be disrupted. I could not feel greater despair over the future."
But, reason to keep fighting:
Others found hope in the climate activism and awareness of younger generations, and in the finding that each extra tenth of a degree of warming avoided protects 140 million people from extreme temperatures.
The Global South? Those people aren't going to lay down and die. They're gonna climb North, as they should. And then we're gonna have to decide whether to shoot people approaching the borders or accept a huge population influx. Given our political reality, I think there's a good chance we try the first option at first.
Right wing parties are already massively strengthening Frontex. They're fully aware what will happen, but still not willing to kill our emissions. "Some of you may die, but it's a sacrifice I am willing to make."
People will be fleeing famine, uninhabitable areas, rising sea levels and wars. The areas that can support life will grow smaller, more valuable and crowded.
What worries me is that combined with anti immigrants sentiment. I fear beaches of dead as people are prevented from fleeing. I read a SciFi with that and it chilled me as I can see it happening.
Will we be assholes if when this happens we be like. WE FUCKING TOLD YOU THIS WOULD HAPPEN, but y’all more concerned with arguing over pronouns and protests (I support both).
I have a postmortem science degree, but hobby in studying paleontology/pre-history. It took a rise of only 10°C and excess pollution to wipe out over 83% of all life on the planet between the Permian and Triassic eras. Entire chains of life just wiped out. Carbon dating, sediment layer study, fossil records, they all show how screwed me are if we keep this up. The earth will survive, it always does, but it took 30 million years before life recovered.
Humans need to learn from the past, see the consequences of what most would think is a small change, but the ones in power don't seem to give a shit.
If you don't mind me asking what does postmortem mean in this context? I have this funny image in my head of a skeleton studying for a degree lmao
Worse. Normal people don't give a shit. Even the ones that are on the team that buys into it don't want to give up much to fix it.
Could you help me understand how we differentiate the latest warming temperatures being related to climate change and not just another period like the one you mentioned?
To be clear, I fully believe that climate change is real, but sometimes when discussing it with people they will be of the camp that things are cyclical and just natural. I want to better arm myself for these arguments.
The used the wrong language even though they need to because they need to be accurate.
"Global South" and "by 2100"
Billionaires: oh so not in my yard and not in my lifetime? Great! Drill baby drill!
Let's stop climate change!
Let's stop it at 1 degree!
Let's stop it at 1.5 degrees
Okay, we might get to 2.5 degrees, but the economy!
This will go on until we get to around 5 degree and most parts of the world have become uninhabitable and most animals and vegetation has gone extinct and we've locked ourselves in perpetual wars due to water and food shortages. Sounds like a shitty B movie, but this is what I truely believe we will end up with.
If it makes you feel any better, once it gets that bad, society will eventually break down and our CO2 levels will naturally return to normal over the next several centuries while the Earth is reclaimed by nature as we go extinct.
I read this headline and think, "this will happen and still nothing will be done."
Fun fact: a lot of mining companies have been incorporating climate change projections into their closure plans for years now, using RCP2.6, RCP4.5, and RCP8.5 scenarios. Hey, we are using a thermal cover to make sure this gargantuan pile of mine waste rock doesn't cause metal leaching/acid rock drainage issues later on: we'd better over-engineer it to take on higher-than expected warming, given that we'll be liable for it for the next 100+ years
Bit of a misdirect in the headline. This was not primarily a scientific projection. This was a political reckoning by scientists who had recently suffered the bureaucratic pain of serving on the IPCC, and voluntarily responded to a survey.
As one climate scientist put it:
"As many of the scientists pointed out, the uncertainty in future temperature change is not a physical science question: It is a question of the decisions people choose to make," Texas Tech University climate scientist Katharine Hayhoe wrote on social media. "We are not experts in that; And we have little reason to feel positive about those, since we have been warning of the risks for decades."
Change never comes from politicians first, but these are people who are zoomed in on whether politicians are changing their minds.
They're not going to change their minds slowly over time. It's gonna be nothing at all until the electorate is too loud to ignore, and then suddenly 100% of officials will claim they've "always condemned fossil fuels", "from day one", and "in the strongest terms possible".
We've seen time and again that policy changes tend to bubble just below the surface for long time and then suddenly emerge with multiple changes happening in quick succession.
I was of voting age when just saying the word "civil union" in the context of gay rights was political suicide, and I'm not that old. Things can change quickly. Keep your hope alive and keep agitating. We can do this.
we need some people, either hacking or inside job, setting the temperature in all conference rooms used by any politicians worldwide 2.5 degrees C higher than normal.
Oh, if only.
The shitty thing is they'd start wearing lighter clothes, and use it as a campaign point that it's not that bad, actually. Power appears to be a hell of a drug.
More like +10.5°C in room A and -8°C in room B.
We're close to blowing past 1.5c
I think we'll blow past 2.5c
I think we'll be looking back, waving longingly to the incredible hulk ending song, to 5c
Because the world doesnt exist to serve the 8 billion humans. It exists to serve a few thousand rich and business owners. . which means as long as there is profit to be had, the killing of the planet and the population will continue not only at pace, but ever accelerating
Seems low.
22% of climate scientists are likely funded by big oil. The other 1% are just normal stupid.
I can see some climate scientists just saying that 2.5C won't be as dire as others predict without being stupid or paid off. There are often contrarians and sometimes (not often, but sometimes) they can be right, so it's healthy to have them even when there is broad consensus. It's how we came to accept ideas like plate tectonics.
So sure, maybe some of them are paid off (I doubt any of them are stupid since they have scientific degrees), but maybe some of them just disagree about the predictions for whatever semi-legitimate or maybe even legitimate reason and that's fine. It's worth exploring why just in case they could be right. The thing is, they're scientists who are dissenting, not just some random guy on Facebook, which is why it's worth exploring them.
There was a powercut this week in a large part of Mexico (I know because of family from there). They're getting rarer now as Mexico has really tried to get its grid uptogether. The downside of countries like this having more stable grids is more people and business installing aircon systems, which just means more energy used, more emissions.
The funny thing is there are ways to passively cool areas. You can literally install shading over windows and walls that face the main sun. Last year in the UK we had a few days where it was over 35C. Nobody here has aircon. So that heat is a shock to us. But I managed to cover the outside of open windows with reflective bubble wrap insulation cut into sheets.
I also installed a small solar system on our shed to run a fridge freezer out there. The funny thing is the half inch stand-offs actively created significant shading and the inside of the shed really cooled down to where we could sit in there and chill out or do tasks without melting. When I realised this I started looking online for research on solar power and shading and found agrovoltaics. Solar panels over farm crops such as fruit in hotter regions mean less watering needed... its more spread out than usual solar farms as it has to let the sun in a bit more to the food but its something that needs to be done more.
I also read of people ignoring their energy policy for their home electric and installing grid-tie solar. They use sheds, stands in their garden, conservatory roofing etc, and usually just a few hundred watts of solar. Typically homes have a fuse rating of 30-50 amps. One 300w solar panel grid tied is not going to be anywhere near that, but will mean up to 300w of clean energy. Energy companies should just allow these systems, even provide them if its a problem or worry to them. You can buy this stuff off amazon for a few hundred quid.
I'm only horrified for all the non-human life we're continuing to decimate on the way out.
Humans don't even seem to tolerate one another as we recklessly decimate this world with technologies we're just smart enough to develop and then immediately use with the same consideration for consequences as a monkey being handed a loaded shutgun, supposedly in humanity's name.
You want us to survive so we can keep a perpetual underclass subsisting in misery? So we can point fingers and call this group and that nation and this gender and that race the problem over and over and over? We are the problem, sorry. Long term, our self-destruction will be a W for the Earth. It will take millions of years, but our mother will eventually clean up our mess we left behind, and continue on like we never existed.
And from my perspective and decades of observation, that is for the best, including for our "everything will be great, once those humans I don't like are shown their place" in perpetuity species.
I've been living in coastal Southeastern Texas for 44 years. Im 46. In 2017 my county rezoned us as a flood zone because of the Havey flooding caused all the poor planning. An entire section of the state reclassified because "interstate highway" needed to be bigger.
They've been building the same 50ish miles for at least 27 years. All they've managed to do is ruin what was naturally occurring barriers and eroded our ability to maintain habitation. Or to expect a reasonable ability to protect against a disaster.
We're leaving 3.4 acres my grandfather bought in 1986, and gave my sister and I in 2007.
And that's just MY story. We had 375 neighbors in my area and at least 30% have moved on since 2017.
And that's just one coastal city, in one state, in one country, on one continent.
I don't have a lot of fantasy about humanities future.
What we need is a Ministry for the Future without a killer heatwave killing millions.
While the developed world rests on its laurels having already developed key technologies that insulate from the worst effects of climate change, the Global South is attempting to push through rapid industrialization to achieve the same effects, bringing with it public infrastructure, electricity, robust food supply, reliable transportation, healthcare...
Meanwhile, the developed world looks at the Global South and says "ah, but why aren't you being greener about it? despicable! how dare you raise emissions?" while simultaneously restricting the free trade of essential green economy components like solar panels and batteries. The fact is, we don't actually care about climate change. Our political entities and economies are not structured to reward innovation in that space, so we simply end up pulling teeth to push through minor advances. Germany used to be a world leader in solar panels before it stagnated due to political pressure. The US used to be a world leader in developing nuclear before it stagnated due to political pressure. Japan used to be the world leader in batteries before it stagnated due to, well, Japan.
We keep doing it because we have to do it, so [the powerful] cannot say that they didn't know," Ruth Cerezo-Mota, who works on climate modeling at the National Autonomous University of Mexico, told The Guardian. "We know what we're talking about. They can say they don't care, but they can't say they didn't know.
It seems to me that we are at such a stage that no matter what we do, there is no turning back. We are doomed, lucky not likely in my lifetime.
Global warming is funny in that there is a threshold at which runaway reaction evaporates all water on the planet and changes it into inhabitable wasteland akin to other sad space rocks.
I don’t know what are the chances for that but I feel if it is anything above 0.1% then it is too fukin big of a chance.
I don’t want to risk that the scientists completely missed the mark in some computer simulation or missed some vital, crucial info and this is the actual scenario, those things are awfully hard to model and predict. Maybe the rate of change is so meaningful that it kicks in some bad stuff that would not happen if the rate of change was hundred thousands years. Who knows at this point. Climatologists are fumbling around in confusion
That won't happen, CO2 and warming has been much, MUCH higher than it is now or probably will ever be.
What will happen is that loads of animals will die because they won't be able to adapt quick enough. Thought that we had many extinctions now? Try a hundred times more.
What will happen is mass crop failures due to extreme weather, and water shortages. Humans being the assholes that the are will not focus on an actual solution, they'll just start wars over the scarce resources to make it even worse.
Humanity actually might go extinct if we let it ge tbad enough.
There are still many people out there claiming it's all fake. Can we please just make them extinct?
A community for discussing events around the World
Rule 1: posts have the following requirements:
Rule 2: Do not copy the entire article into your post. The key points in 1-2 paragraphs is allowed (even encouraged!), but large segments of articles posted in the body will result in the post being removed. If you have to stop and think "Is this fair use?", it probably isn't. Archive links, especially the ones created on link submission, are absolutely allowed but those that avoid paywalls are not.
Rule 3: Opinions articles, or Articles based on misinformation/propaganda may be removed. Sources that have a Low or Very Low factual reporting rating or MBFC Credibility Rating may be removed.
Rule 4: Posts or comments that are homophobic, transphobic, racist, sexist, anti-religious, or ableist will be removed. “Ironic” prejudice is just prejudiced.
Posts and comments must abide by the lemmy.world terms of service UPDATED AS OF 10/19
Rule 5: Keep it civil. It's OK to say the subject of an article is behaving like a (pejorative, pejorative). It's NOT OK to say another USER is (pejorative). Strong language is fine, just not directed at other members. Engage in good-faith and with respect! This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban.
Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.
Rule 6: Memes, spam, other low effort posting, reposts, misinformation, advocating violence, off-topic, trolling, offensive, regarding the moderators or meta in content may be removed at any time.
Rule 7: We didn't USED to need a rule about how many posts one could make in a day, then someone posted NINETEEN articles in a single day. Not comments, FULL ARTICLES. If you're posting more than say, 10 or so, consider going outside and touching grass. We reserve the right to limit over-posting so a single user does not dominate the front page.
We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.
All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.
