Holy crap. So coral bleaching in that area is basically guaranteed at this point. And some plankton and algae can’t really survive if those temperatures persist.
Also, as temperature rises, water holds less and less dissolved oxygen. At the same time metabolic rates of fish increase, which makes them require even more oxygen. The scary thing about that is at some point they lose the ability to get enough oxygen to sustain life, and then bam — the whole species dies in a day.
Or the 2000 dead penguins washing up on the coast of Uruguay just a few days ago. Apparently starved to death, though the cause is still being investigated.
But yeah the phytoplankton and algae boiling to death is triggering a catastrophic change in the ocean that is going to domino in horrible ways and I feel like I don’t often see a lot of people mentioning it. It’s very scary how the collapse of aquatic ecosystems is playing out.
All of these things are bad, but the effect on phytoplankton is most frightening of all. Diatoms provide 50-85% of our global oxygen supply. Not only are rising temperatures a problem for them, but ocean acidification also eats away at their silica-based shells. But it does it slowly so by the time they die, they are in deep water where no other diatoms are around to reuse the silica.
Luckily, there are other ways of recycling diatom remains. The most notable example is the dried lake bed that used to be part of Lake Chad when that lake was far bigger and held many living diatoms. Due to natural changes in climate, the water dried up and that area is now part of the Sahara Desert. About 100 days a year, winds kick the ancient diatom dust high into the atmosphere where it is carried across the Atlantic Ocean and then it settles across South America.
This is a big reason the Amazon Rainforest is so lush. Diatomaceous fertilizer carried all the way from Africa. And since more plants means more photosynthesis, it causes a lot of water that would have otherwise been locked away in the ground to evaporate through transpiration. All of this excess water is blown westward towards the Andes mountain range. In narrower parts of the Andes, the dense Amazonian clouds overcome the rain shadow effect to precipitate across the west side of the Andes.
This rainwater causes erosion of quartz, which is ground into fine silica dust. As silt, this dust is washed into the Pacific Ocean, where diatoms absorb the silica and use it to reproduce. In a beautiful global balancing act, as diatom-heavy lakes in Africa dry up, the remains of those diatoms cause a chain reaction that ends up causing a huge increase of diatoms on the opposite side of the globe.
Great, right? It would be if we weren’t replacing so much of the Amazon Rainforest with monoculture farms which don’t have nearly the same evapotranspiration effect as the flora of the natural ecosystem. So, not only are we baking the diatoms, not only are we dissolving them with acid, we’re also removing one of their most critical reproductive resources.
It’s like we discovered how resilient the planet is and how hard it is to kill, and humans took that as a challenge.
That’s a great write up, thanks. Haven’t heard about the connection between the Amazon rainforest and African diatoms, that’s fascinating.
I thought lake Chad started to dry up mostly in the 60s. I went to read some more about that and I just can’t not mention that the original lake is apparently called Mega-Chad :)
Anyway, in case anyone else is interested to read about ancient microorganisms fuelling Amazon’s growth, here’s a really interesting paper that describes this system in great detail.
The only realistic way to “lose” O2 is to convert it into CO2. And even if enough CO2 were produced to extinguish humanity forever, there would still be plenty of O2 left over. So “running out” of O2 is not a serious concern.
Yes, in the long term, the planet will be fine. But bear in mind, our entire biology is based on converting O2 into CO2.
I mean, sure, a couple billion years ago, the global ecosystem had the opposite problem and single-celled archaea was suffocating the planet with too much O2. Those are the conditions that allowed animal life to evolve.
So, I take your point that the planet will still have O2 long after we flood the atmosphere with the millions of tons of CO2 that used to be buried deep underground. Plankton will have a comeback even if the vast majority of animal life on the planet dies of asphyxiation first. But at that point, the argument of whether we’ve “run out” of O2 is really semantics, right? If we haven’t “run out” of it, but our supply gets low enough that virtually all of us are dead as a result, I don’t place a lot of value in making that distinction.
Our atmosphere is 21% O2, and less than 0.05% CO2.
If that changed by 1% to 20% O2 and 1.05% CO2, we would all die. But not for asphyxiation or lack of O2, because the slight reduction in O2 would be unnoticeable. The drastic increase in CO2, on the other hand, would be catastrophic.
It’s encouraging, but we shouldn’t rely on it to fix our problems. The good thing is that there are many thousands of varieties of diatoms, each with their own odds of adapting and overcoming the situation we’ve put them in. I have confidence that the planet will survive. But whether enough of these phytoplankton will evolve in time to keep catastrophic extinction events from occurring is still very much in question. We should do everything we can as a species to protect their health.
No, we cant rely on it to fix our problems. Hell if anything it will adapt and then get exploited later on. Humans just ruin everything…
I wish we were better and hope that we will do a 180 and try to preserve what is left, but I wouldnt bet on it.
As much as I’m genuinely fearful of what we are going to endure in the coming years, especially the next generation, part of me feels like we deserve what we get. All we can do is prepare the best we can, cross our fingers, and ride the ride.
It’s pretty shitty that we’re taking everything else down with us, but it does give me hope that maybe nature will surprise us, and not all will be lost, even if it seems that way.
Maybe read the article before being a total shitass.
While the readings would’ve been considered a possible outlier or sensor error, surrounding buoys recorded similarly high temperatures, with 99.3 F at Murray Key and 98.4 F at Johnson Key.
The title “TikToker who debunked Jason Aldean’s ‘Try That in a Small Town’ video…” is a little silly and confusing but the TikToker, Destinee, was pointing out how racist the music video is and also debunked Jason Aldean’s claim that all the music video footage is exclusively real American protests.
She debunked that "“there isn’t a single video clip that isn’t real news footage,” as Aldean said in defense of the music video. She showed that some of the footage was from a an event in Canada, and a protest in Ukraine, as well as some stock footage. The article explains more.
there are a bunch of black people in this reaction video saying it isn’t racist. watch the reaction video then come back and let me know what you think about the reaction video.
Edit: I like how people are downvoting me. I wonder how many of them are white. Watch the reaction video, then come back and let me know you actually watched the reaction video all the way through. Also let me know if you are black or white. What I’m trying to figure out is what percentage of people that are pissed are they white or black. The more knowledge we have the better off we are.
When I first started hearing about this song, and they were people feeling was racist, I thought maybe I should start asking is it racist or not?. I am a middle-aged white guy, so I’m probably not real well qualified to determine what it is or is not racist towards Black people. I can make an assumption of how people, Black people, might view it. But I’ve never walked in the shoes of a black man or a black woman.
I’ve never been pregnant and I’m not a female so there’s no way I can know what it is like to be pregnant. Nor can I figure out what it is like for the emotional stresses of what a female goes through. I can make an assumption or a guess that a certain situation might be stressful or that a certain certain situation a female might not like, but I am not a female so I cannot know it for a fact. So I would have to go talk to a female.
I’m not a Marine so there is no real way for me to know what a Marine goes through.
So I thought the best way to figure out of what do Black people think about this video is effectively go online and look at YouTube videos of Black people responding to the video. That is why I am encouraging those who are down voting this to go watch that video and then come back and respond and tell me what do you think of that video. And also to state are you black or white. for example if I get a bunch of Black people come in here and tell me yes it’s racist as hell, well then obviously that’s where Black people are at and I need to listen to that.
That’s a terrible way to judge it. Part of the effect of systemic racism is that it obscures itself. Part of the tactics of white supremecy is to gaslight and deny. The people who chose to shoot this video at the site of a lynching and race massacre know that this video is racist as fuck, but they deny it and obscure it. It’s dog whistling and it’s not even that subtle.
I’m sure if it ask Kanye or Clarence they have no problems with the messaging in the video. Maybe it’s because they are tokens or maybe it’s because they don’t recognize the symbolism of lynching black people at a courthouse.
What do academics and social scientists say, students of history and anthropology?
The video says that in small town, the law will not protect you from extrajudicial murder if you burn a flag, which is a lawful, First Amendment protected activity. Any attempt to deny, excuse, or justify this messaging is yet another act of complete, unironic ignorance, or is intentional gaslighting.
I clicked on the link and literally none of the top comments are from black people, they’re from white people, so something is certainly wrong here and I don’t think it’s those downvoting you
What’s happening here is very typical with marginalized communities, pandering to White Supremacists to gain some semblance of respect. It isn’t the first time this has happened. Shall we take a walk back down memory lane to the time Malcolm X sat beside George Rockwell?
When I first started hearing about this song, and they were people feeling was racist, I thought maybe I should start asking is it racist or not?
If you read the article and watch the TikTok video a person of color is telling you that she considers it racist. It’s fine if some other PoCs disagree. But the discussion here started with the opinion of Ms Stark.
It’s been 20 years since broadband became fairly ubiquitous, there is 0 excuse for telcos to milk us like this, bandwidth gets so much cheaper for them every year.
The 25/3 bar was specifically lowered to that so that 4G LTE would meet this bar and they could claim that 99% of Americans now have access to high-speed Internet for political points.
Realistically, if it were up to me, I’d say anything 25/3 and lower is “low-speed”, between 25/3 and 100/10 is “standard speed”, and set the bar for “high-speed” to mean 100/10 or better. Companies should not be allowed to advertise “blazing-fast high-speed Internet” and then it turns out to be 30/3 ADSL for $50 a month
You might be right, I thought it was actually for adsl, because otherwise post-bells had to roll out fiber or comcast were the only high-speed isp.
The problem is most people can live on 25/3 or less, stick to youtube sd, email, web, etc, it’ll be slow but not ludicrously so, and they won’t complain much.
Not a lot we can do, the limit on bandwidth means we are stopped from creating services that need more bandwidth, which means they’re no reason to get that bandwidth.
HD video is nice, but not a requirement for most people, and ISPs desperately want to keep their customers limited so they can either upsell traditional tv/voice or otherwise keep their customers from adventuring too far outside their walled gardens. AOL both helped deploy and was destroyed by the internet, modern ISPs don’t want to see the same thing happen to them, and honestly most customers use a handful of common sites.
Yes. We need the numbers to be minimum bitrates and we need at least a 90% uptime for that minimum. If you could rely on your bandwidth to be a specific rate all the time you could pay for less and everyone could get more without more infrastructure upgrades.
There is multiple tipping points, as counterintuitive as that sounds. Just means there are certain things that cannot be repaired once they are destroyed.
Absolutely not. It depends more on what you're doing, rather than number of people, anyways. One person uploading a video is going to use 99% of the available upload bandwidth.
That’s a traffic shaping problem, not really on the person or service. Streaming would be a better example because that’s immediate and you care about uploading in a timely fashion and best quality, but if you limit your upload bandwidth you can manage it better…
But then again we’re talking about upload, in general, upload only matters in a few situations, latency will be more important, and download is always more noticeable than upload speeds.
Even doing making youtube videos the only reason you need instant fast video upload is if you’re trying to push drama videos, and even then, I’m probably fine with them being slightly limited by that. But ultimately uploading videos is only slightly inconvenient for modern broadband, if it’s that bad, look into how to limit how much bandwidth it takes up, there’s good ways.
It doesn’t matter what they are. That’s how TCP is designed to ramp up until it fills the pipe. Upload a large continuous file and you will fill the upload until it’s done.
Yes. The point is how long it cripples a network, due to the extremely poor upload rates allowed by service providers, is unacceptable. I'm not sure what's confusing here. It should be barely noticable by other users because it should be FAST.
That's due to the shit queuing most ISPs implement. You can limit your bandwidth below your actual limit on your router and do your own queueing that prioritizes TCP acknowledgements and you won't destroy your connection when you hit max upload.
Exactly. I had to implement QOS on my network otherwise my backups would kill my Internet connection. Now at least I can leave everything at 100% upload rate and let the network devices handle my traffic.
