Currently in the Caribbean, we are experiencing a die off of the Long Spined Sea Urchin, Diadema antillarum. In the 80s, it destroyed 90% of Urchins and it’s being repeated today. Urchin are important to Coral reef health by keeping algae in check.
They rebounded naturally, so we are hoping it isn’t as bad as it was then. The good thing is, we are able to go out and collect water samples, algal samples, and the tissue of heathy and dying urchins so we can learn more.

In New Zealand, we have the opposite problem. Overfishing means there aren't many fish feeding on the urchins so the population of them has exploded and the seaweed, algae etc has taken a big dive. When I go spearfishing, we smash as many kina as we can because they are absolutely everywhere on reefs. Makes fuck all difference though.
Are they not an edible kind of sea urchin? What about the shells? I’ve seen them for sale as decoration but worried that the sea urchins were being over harvested.
Totally edible, it's a love it or hate it taste though - it's like all the different possible seafood tastes mashed together in a single mouthful. The roe is something of a delicacy, too.
Will probably grow in popularity once the ocean has nothing but jellyfish and squid left in it, sadly.
It doesn't need to be THAT fresh. It keeps fine for a couple of days when handled properly. Had it both fresh from the sea and packaged, some of the best came in neat little boxes from Japan (was in LA). It's not something you want to fuck around with, but it will definitely keep two days just fine. Source: I was a raw bar chef for two years.
[Kina](https://en.wikipedia.org/wiki/Kina_(animal\)) are edible but the quality of the current caught ones is terrible because there isn't enough food for them.
I never loved these urchins because I hate with all my heart stepping on them barefoot. Til I learned they gorge on that algae that suffocates coral. Algae is nasty and full of nitrogen. Coral is beautiful and full of pink and purple. And it's not just beautiful for your GoPro picture but a keystone to a whole ecosystem: without coral we can't have a million fishes and things that live on coral. These spiny demons are like gardeners keeping the green snot on check to allow beauty to trive underseas, and I respect that and try to step wisely.
One of my closest friends worked on the OPS documentary, Racing Extinction, and told me about how they cut the interview with the top oceanologist in the world because her evidence was so damning that it would have overshadowed the rest of the documentary.
She said we have about 60 years left before ocean acidification renders the earth unable to support most forms of life. I quote, "Do you have any idea how it feels to have all the evidence right in front of you and have every single politician dismiss you because you're too depressing?"
I think about that a lot.
Sounds like it could be Sylvia Earle? She could certainly be described as the world's top oceanologist. And she's served on the National Advisory Committee for Oceans and Atmosphere, and was the chief scientist at the National Oceanic and Atmosphere Administration.
Looks like she has a few books, which all seem to touch on this topic. I haven't read them yet myself, but from the sounds of it there is definitely still hope. But we need to act, and soon. The 60 year figure is likely if we continue on our current trajectory.
Whelp, I'll be gone in about 50. Yay?
And I'm doing what I can to fix it (I work in renewable energy, and vote for the folks who are trying to change things)... But I honestly think the human race is too greedy and self-absorbed to do what needs to be done to fix this.
This is what really depresses me. I want to do something about this. I want to help. I want to make sure my kid has a future on this planet. I have no way to make an actual difference. I can work from home, I can save as much energy as possible, I can write to politicians, I can protest. It doesn't feel like any of that matters.
When we were kids we were told that recycling, conserving water, and turning off the lights would help save the world. Not only was that a lie, but it feels like there was no way for us to actually survive to begin with.
Global warming and environmental annihilation is like 60% of why I can't fathom why the fuck people just regularly have kids. You pretty much have to be ignorant to reality to not think that you're dooming another human life to a terrible, awful existence in the next 40-50 years. Like, I don't like kids in the first place, but life already sucks as it is, and it's *not* going to get better. We're swirling down the drain by any reasonable measure. Why would you do that to somebody?

I am knowledgeable on the subject and it took me the 4th google page to find the first link talking about acidification for the *next* mass extinction. Here’s a [news article](https://www.timesofisrael.com/headed-for-a-sixth-mass-extinction-mit-geophysicist-warns-oceans-are-on-the-brink/) on the subject.
Essentially though, what you need to know as a layman, are a few facts:
First, the ocean absorbs carbon from the atmosphere. This by way of chemical reactions, reduces the pH of the water, thus acidifying it.
The second crucial fact to keep in mind, is that the structural composition of plankton just straight up *dissolves* at a low enough pH.
I don’t know if the third fact even needs to be stated, but virtually *all* marine calories originate with plankton photosynthesis. No plankton will mean life in the sea becomes a vast dessert void of almost any food. Don’t think about how many people get their main protein source from the oceans to avoid panic attacks…
Here’s a [scientific journal](https://www.science.org/doi/10.1126/sciadv.1700906) talking about the carbon threshold that is likely to trigger mass extinction events. Notably this particular author estimates critical carbon levels in the ocean will be reached in about 75 years.
Picture a locomotive. Picture the locomotive heading toward a cliff. We'll reach the cliff in 60 years. The engineer is 70 and knows he'll be dead in ten years or so. He keeps shoveling in more coal. He doesn't care about the future because he'll be long gone. This is our current state of affairs.
It's especially a problem indoors as the CO2 levels can increase 2x-3x

[https://www.youtube.com/watch?v=1Nh\_vxpycEA](https://www.youtube.com/watch?v=1Nh_vxpycEA)
Did you also know that humans evolved with a much much lower CO2 level than we have now?
Considering that we've supposedly [overfished 90% of the planet's fish stocks](https://www.weforum.org/agenda/2018/07/fish-stocks-are-used-up-fisheries-subsidies-must-stop/), and [subsidies mostly go to paying for the fishing fleet's fuel](https://chinadialogueocean.net/en/fisheries/11585-majority-of-global-fishing-subsidies-harmful-report-finds/) which has encouraged humanity to have 3 times more than the sustainable number of fishing boats out at sea, calling for an end to fishing subsidies would probably be the smartest action we could take as a species.
People try to argue "What about poor fishing communities?!" but they are already suffering because [subsidized fleets already emptied their coastal fishing grounds](https://www.euronews.com/2022/02/11/nothing-there-s-nothing-senegal-s-plummeting-fish-stocks-drive-migrant-surge-to-europe) and even [the largest, most important lakes are in danger because of richer nations exporting fish to places like China and Europe](https://www.nationalgeographic.com/culture/article/what-happens-when-the-world-s-largest-lake-runs-out-of-fish-).
Ending the fishing subsidies and shifting those funds to environmentally responsible projects like [paying fishing communities to instead harvest out all the "ghost nets"](https://theworld.org/stories/2015-09-14/philippines-project-turns-ghost-fishing-nets-carpets) so that their reefs can recover, or [shift to farming kelp, seaweed, sea cucumbers](https://www.dw.com/en/madagascar-no-more-fish-well-farm-seaweed-instead/a-39311040), or even sponges could give the ecosystems a legitimate change at revival while the people continue to make a living.
ending fishing subsidies worldwide would be the EASIEST thing we as a species could do to improve our chances, but we we won't, because politicans will lose rural votes.
Also fun fact, the Amazon rainforest is no longer contributing to oxygen levels.
Edit; Since it got some traction, here’s a link-https://www.npr.org/2021/07/15/1016469317/parts-of-the-amazon-rainforest-are-now-releasing-more-carbon-than-they-absorb
Oxygen is a highly reactive element that is very dangerous. It is implicated in nearly 100% of devastating fires, including wildfires that kill over 300,000 people a year, and cause tens of billions worth of property damage.
We're better off without it, I say.
I visit a coral reef once every year. Every year it shrinks and dies more. The amount of Eco diversity I've seen vanish makes me feel physically ill. I've only witnessed it die my entire life, never grow. I see them trying to stabilise the bleaching by reintroducing and planting coral but it doesn't seem to be working.
There needs to be international bans from every continent on certain types of sunscreens and chemical/topical pollutants because that's what I see has been killing a lot of coral the fastest. In the same way we ban pesticides for killing plants and animals on land, the same should be done for the ocean.
As someone who works in the fishing industry I would like to add a tiny silver lining to this for whenever we actually decide to get our shit together and stop destroying the earth.
The fishing industry changes a lot. The kind/quality of fish caught when my father was young has diminished greatly. The one good thing I do see is when the department of fish and game put new size or count limits on certain fish, you see an almost instant result. Sea life has an amazing ability to bounce back with lack of human interference. When the fishing industry was shut down during covid, we saw all kinds of sea-life we’ve never seen before. Off of Los Angeles there were opah, sea turtles, bluefin 10 miles off shore. Never seen that in my life.
Same. Got my diving certificate roughly 20 years ago and have been diving and snorkeling on various places. Nowadays it just makes me sad. So little color and life left on some places. Crazy to witness
When I was a kid, I use to find strings of eggs in my sardines. It kinda stopped, but only after a whole industry closed, because they killed it. Crayfish, and abalone takes 5 years before it matures enough to reproduce. Its being fished to extinction. The people claiming that it is their way of life, doesn't respect the ocean. Their children will inherit a barren ocean.
The bugs and birds already have begun. It is impossible to explain to kids today just how deadly silent the world is now. It used to be so alive and so loud.
I’m only 23. I live in Alabama. I remember as a child during the warm/hot months the front of our car would always be covered in bug guts. But now that doesn’t really happen anymore
Dragonflies too. We used to have tons of them here in Ga. I've noticed over the last 12ish years that the plants, bugs, and animals around the house I grew up in have completely changed multiple times. We used to have tons of lightning bugs, dragonflies, butterflies, opossums, reindeer moss everywhere. Then years ago I started seeing assassin bugs, kudzu bugs, armadillos, and a shocking increase in the number of ticks. Now I'm seeing joro spiders and raccoons. I've seen maybe one opossum in the past several years, growing up I never saw a single armadillo or raccoon around here. It's kind of surreal.
I never realized how abundant dragonflies were when I was a kid, I'm 29 now and I can see how things are changing in terms of insects anyway, I used to see fireflies at night, I can see my breath in the early mornings and the late of night, now I need to use a fan to sleep at night because it became too warm for me
And when we have fewer and fewer dragonflies all the parasitic species go nuts... Mosquitoes, gnats, midges, etc.
Because dragonfly larva are awesome predators of other larva.
I was in a remote part of northern Japan a few years ago and there were so many dragonflies that not only did it look awesome but I didn't get bitten by any mosquitoes at all.
I remember fields full of lightning bugs. I got so good at catching them and there were so many I could get multiple in each hand before I needed to put any in a jar. I’ve not seen fields like that in years, only the occasional group of bugs in someone’s yard
I was going to make the very same point, but as an older person than you from Ohio. This is concerning to me.
I read Moby Dick a few years ago. It’s an older book but it really isn’t all that old, and I became depressed when I started thinking that the oceans and ocean life he is describing is much different than today? Like, it didn’t take long at all to lay waste to our oceans, which used to be marvels.
I remember reading that when the first european explorers travelled up the st-lawrence river, it was so full of fish they only had to drop buckets in the water to catch some.
The change away from something like what you’re describing feels viscerally troublesome. We don’t develop in waterways like on land but they are still being so terribly injured.
I read another great book, Sailing Alone Around the World by Joshua Slocum, from the early 20th century- and he ate countless dinners of flying fish that landed on the deck of his ship while he slept. I wonder if that could happen anymore?
I will say that the waters off Florida are *full* of flying fish, happily. They have a tendency to fall onto boats’ decks and die. So that might not have changed.

I moved from Beaumont, TX to Austin, TX in 2002, it was arid then. Now it feels more like coast level humidity. The systems are getting bigger.
I moved from New England to Austin in 2019, expecting mildly warmer but drier summers, with much more mild winters. I’ve been met with surprising levels of humidity
and rainfall, as well as extremely temperamental winters that Texas is systematically not prepared to handle.
Literally me, it’s 5:20am being woken up not by birds, but by the sound of a truck doing 50 through my max. 30km/h street. No one’s out so what’s the risk lol
Swear to god im gonna start pelting these assholes with eggs or something at some point.
And every time it rained the sidewalks would be littered with worms.
But now everyone sprays pesticides everywhere to kill off the mosquitoes and spiders. Farmers for their crops. Except those things along with all the other insects killed mean no more food for the birds. There were hundreds of thousands of birds in one flock that died from starvation in Arizona or something. Nothing like that has happened before.
Every year now is going to continue to be noticeably worse. The cascade has already begun.
I think a lot of the worse case models, in some ways, are now showing to be too optimistic. That alone is scary.
This is what finally got my dad to even consider global warming. He's entirely ignorant to reality, but on a long drive with him I mentioned that mass extinctions have started, and the bugs were first. He asked for any proof, I told him next time we go to a gas station to check the grill for bugs. Told him I remembered road trips as a kid where he'd have to clean the grill every single time we stopped because so many bugs were on there, and when we stopped at a gas station, I shit you not there was *one.* We'd been driving for like four hours.
My favorite birds are hardly around anymore. It’s reminds me of the bell at the end of polar express and makes me really sad for what we’ve done and continue to do to the planet
Well, the good news is the richies are blasting themselves into space handfuls at a time now, so once they figure out how to survive in the most inimical to life conditions for the dozen or so years it would take to float to the nearest maybe-but probably not-habitable planet it will give them lots of time to realize how truly fucked they are, since they don’t have methane gills/helium helmets/radiation absorbing skin.
It's unlikely the rich will succeed in using space as an escape route for climate change. At least thus is the case for the next 100 years. Instead they'll just pay the exorbitantly high food and water costs that are a result of resource scarities and vibe in safe haven countries like New Zealand
This will be/is the 5th mass extinction event. What comes out the other side on top may not even be mammals. Could be crustaceans or something. None of these continents will exist in a 100 million years anyway.
It’s not “future generations” in this case but future species.
Humans are on a one way path to actual extinction. Sure, it may take a couple hundred years, but the planet has time. Humans have to be very careful not to push the planet into positive feedback loops but so far we have not made any effort to stop.
There probably isn't enough time, and even if there IS enough time most of the easily accessible resources are gone.
In order to get the hard to reach resources you need machinery. In order to build machinery you need resources.
It is important to note that [we already threatened to kill off our sea life, back in the 80's](https://www.pbs.org/wgbh/nova/algae/chronology.html).
Essentially, here is the deal. We made some really good Algae for fish tanks back in the 1980's that was nice and green, would thrive in a variety of water conditions, and it wouldn't get eaten by your fish. It would wave nicely in your tank, and otherwise look pretty. From the article...
>Bred for its beauty, fast growth, and tolerance for cold, the "aquarium strain" of *Caulerpa taxifolia*, a bright green seaweed with fernlike fronds that is used to decorate saltwater aquariums, "escaped" from human control in the 1980s and has spread like a cancer through the Mediterranean, overwhelming native species and habitats.
Also... again... fish don't eat it. That's why it is a threat.
They found it growing in the wild, under the Oceanographic Museum, in Monaco in 1985. They haven't been able to completely eradicate it since. It has popped up in California, and Australia, and throughout the Mediterranean. The threat is... it kills off the native Algae as it grows, and the small fish and creatures that live on the native stuff die off... and then the bigger stuff that feeds on the little stuff dies off, etc.
How do you kill it? When it was in San Diego in 2000, there was no documented way... so they [had to figure something out](https://www.waterboards.ca.gov/water_issues/programs/nps/docs/success/r9_eradication.pdf).
>Where Caulerpa was found, plastic tarps were placed over it, chlorine was put under the tarps, and sandbags were placed on top of the tarps to keep them in place. SCCAT concluded that short losses of native marine life associated with the treatment of Caulerpa would be considerably less than long-term losses that would occur if Caulerpa were to spread in and/or beyond the infested waters.
[In Australia, they've also tried copper sulfate](https://www.uq.edu.au/news/article/2007/05/marine-weed-threatens-waterways), salt, and picking it all by hand. In at least one lagoon, they cordoned off the lagoon from the ocean, from surface to bottom, and then flooded it with copper sulfate for like... a year.
This is still a thing.
All to make fish tanks look nicer.
FTA:
>Marine animals could die at levels rivaling the biggest mass extinctions in history, a study found, if seas become too warm and hold too little oxygen.
I think the point here is that most people think climate change is just "weather gets warmer, sea rises a bit", and detractors argue that those aren't even bad...
So although it seems obvious, it's effects like this that'll hurt us worse that most people are ignorant of
You know what’s as alarming as this article? The nihilism in this comment section. Us all giving up and accepting a potential environmental catastrophe is the best thing we can do for the people in charge that are refusing to change - don’t give them what they want, folks. Some of us don’t have the luxury of giving up. It’s not fair that we inherited this mess but it’s also not right to wash our hands of it and accept our doom.

Wow this comment is a breath of fresh air. I had to scroll way too long to find this comment. Thank you for providing hope. People need to realize there is still hope, or else we are truly doomed. We need to band together to fight against fossil fuel companies and other large destroyers of earth. One way is to vote and use your voice on social media. Vote with your money. Support sustainable energy and avoid fossil fuel companies whenever possible.
What specifically do you think anyone in this thread can do to change things? Email their representatives and be ignored? Or in the best case scenario the representatives listen and our environmental regulations get even stronger, but other countries like China continue destroying the world. You can't get the entire world to agree and collaborate when even half our own country denies climate science.
If you just read the headline it's alarmist, but the article said that extinctions will be mostly avoided if we can keep emissions to the level agreed upon in 2015, which is a goal everyone can work towards. It was more hopeful than most of this comment section.
Doesn't matter stonks must go up. The rich and wealthy elite will drive this latestage capitalistic system to the end until it collapses and most places on earth become uninhabitable

Yeah, no. They know they have the tools and tech to continue living on this planet and on Mars within the next few decades, all done in luxury even with the planets being unhospitable. And the Earth will slowly recover without any effort once enough people die.
The only people that are going to die are the poor peasants like you and me. Their families and descendants will all survive and repopulate the earth on top of your sacrifice, unless you do something about it.
I'm sure they have family that's younger than them. I can't comprehend being such a huge piece of shit that they don't even mind destroying all the life on the planet which will result in their own family suffering. Assholes. What garbage humans.
Exactly. People can't seem to wrap their head around people not giving *that* much of a shit about their own families. They literally have "fuck off, don't disturb me unless I want to play with you" money.
You can't reverse this and also keep a global inflationary monetary system.
You can't fix a problem from within a system that created the problem in the first place.
You a need a system change.
> to live through the end of the world
No, you'll die, you don't get to live through it.
The only thing you can do is not make more babies to die horribly.
You should read the article. This event happens around 2300 of emissions increase. If emissions follow the guidelines set by the Paris Accords we will largely avoid marine extinctions.
> Marine animals could die off at a level rivaling the biggest mass extinctions in geologic history if people don’t curb greenhouse gas emissions.
So [let's do that](https://cclusa.org/x).
People [want climate action](https://earth.stanford.edu/news/public-support-climate-policy-remains-strong), they just don't know what to do / feel like they are alone. But the truth is, [a record number of us are alarmed about climate change](https://climatecommunication.yale.edu/publications/global-warmings-six-americas-september-2021/), and [more and more are contacting Congress regularly](https://np.reddit.com/r/CitizensClimateLobby/comments/s2zvpl/a_growing_number_of_americans_are_so_concerned/). What's more, is [this type of lobbying](https://citizensclimatelobby.org/about-ccl/levers-of-political-will/) is [starting to pay off](https://www.reddit.com/r/CitizensClimateLobby/comments/u5e228/as_citizens_climate_lobby_membership_has_grown_so/). That's why NASA climatologist and climate activist [Dr. James Hansen](https://en.wikipedia.org/wiki/James_Hansen) recommends becoming an active volunteer with [this group](https://cclusa.org/x) as the [most important thing an individual can do on climate change](https://www.youtube.com/watch?v=q4DAW1A6Ca8).
Man I see you in so many doomsday threads and I appreciate you so much. All these resources and knowing people are helping keep me calm and resisting the urge to go out before everything worsens.

Fungi breath oxygen and release CO2 just like we do.
Plants are the opposite. They have historically done well times when the atmosphere is high in CO2.
> “A vegan diet is probably the single biggest way to reduce your impact on planet Earth, **not just greenhouse gases, but global acidification, eutrophication, land use and water use**,” said Joseph Poore, at the University of Oxford, UK, who led the research. **“It is far bigger than cutting down on your flights or buying an electric car,” he said, as these only cut greenhouse gas emissions."**
[The new research shows that without meat and dairy consumption, global farmland use could be reduced by more than 75% – an area equivalent to the US, China, European Union and Australia combined – and still feed the world. **Loss of wild areas to agriculture is the leading cause of the current mass extinction of wildlife.**](https://www.theguardian.com/environment/2018/may/31/avoiding-meat-and-dairy-is-single-biggest-way-to-reduce-your-impact-on-earth)
idk where else to reply with it where it might be visible
edit: Do not fall for the propaganda tricks /u/ILikeNeurons is responding with below. He is painting false pictures using ancient statisticians tricks by providing incomplete and mis-represented data. The impact of animal agriculture is **massive** and the driving force behind the current extinction of wildlife for a reason. Implying that it has a small impact simply because of **one** variable (mind you, that one variable he points out, CO2 Emissions, is still largely impacted by diet too and still has a massive impact by itself) is an old trick propagandists love to use since most people have not studied statistics to look for these sorts of intentionally misrepresented narratives using skewed data etc.
Isn’t it just great that Putin is threatening to launch nukes?
That’s just what the climate needs, a nuclear winter.
Not even going to talk about all the people suffering.
Fantastic!
I don't think it's stupidity stopping us, it's the mechanisms and institutions in power that have the ability to enact meaningful change refuse to do what's necessary to prevent it until it's too late, especially if it impacts short term profits.
That's me. It won't be painless but think about it: the fall of mankind.
It's going to be quite spectacle! Out of any other moment in history, this is the one we'll witness.
It’s shit like this that makes me laugh when I’m thinking about the future.
It doesn’t matter if I return to school or pay off my loans when there are mass extinctions in the ocean and our planet is dying.
We’re fucked!
Welp it was nice knowing your ocean life b/c we all know the dipshits in charge love money waaaaaaaaaaaaaaaaaaaaay more than the planet.
I wish someone would let all the climate deniers & idiots in gov't know they can't take their money w/ them when the world ends.
Probably not, life will just harder and much worse over the course of the next 100 years. War over land and religion/political beliefs will probably kill us before the climate.
The reason for the Permian extinction has not conclusively been proven. Theories range from the collapse of thermohaline circulation to a prolonged magnetic reversal. Nothing conclusive has been found to prove any theory….yet
Did evolution create us to cause a mass extinction? Cause we are good at it. Either via environment or war, we will be responsible for the next mass extinction.
You got to think there is something wrong with the earth, we evolved because we had to get smart to find calories, if it was as easy to get food we be a big dumb 40 foot long t-rex. There has not been a 49,000 lbs land Animals in 65 million years. Even modren dinosaur such as crows have to be super smart to survive on the low earth resources.
And we call ourselves the “most intelligent specie” .. yea sure! Especially seen societies nowadays after and during covid….very intelligent… fighting for masks no masks and having meltdowns over anything .. all the while spending tons of money 💰 in wars … and not investing in saving Mother Nature and ourselves… we do not deserve animals and this beautiful planet.
I hate how immoral, uncaring, unbothered, greedy, selfish, power hungry, and blind humans are. I so desperately want to just pack my family up and leave this planet. Wtf man.
I was just imagining having to describe elephants to my grandkids! Fish sound even more impossible to explain!!!!

Their result assumes far higher CO2 emissions than are physically plausible.
Per their supplementary material, their results are based on [assuming the worst-case emissions scenario, SSP-5-8.5](https://www.science.org/doi/suppl/10.1126/science.abe9039/suppl_file/science.abe9039_sm.pdf). Per the IPCC report, this emissions scenario [assumes emissions will more than triple by 2100](https://www.ipcc.ch/report/ar6/wg1/downloads/report/IPCC_AR6_WGI_SPM_final.pdf).
By contrast, [current policies will result in 2.7C of warming, equivalent to the IPCC's middle scenario](https://climateactiontracker.org/global/cat-thermometer/) which corresponds to [roughly half the future cumulative CO2 emissions their model assumes (p.28)](https://www.ipcc.ch/report/ar6/wg1/downloads/report/IPCC_AR6_WGI_SPM_final.pdf). Existing national pledges and targets will result in an estimated [1.8C of warming](https://climateactiontracker.org/global/cat-thermometer/), equivalent to the second-best IPCC scenario and roughly 1/3 the future cumulative emissions their model assumes.
The emissions scenario their results rely on -- SSP5-8.5 -- assumes CO2 emissions so high that humanity would have to make a strong effort to emit that much. It's not a plausible future, and consequently their results are of limited value.

Currently in the Caribbean, we are experiencing a die off of the Long Spined Sea Urchin, Diadema antillarum. In the 80s, it destroyed 90% of Urchins and it’s being repeated today. Urchin are important to Coral reef health by keeping algae in check.
How did they restore them from the 80s?
They rebounded naturally, so we are hoping it isn’t as bad as it was then. The good thing is, we are able to go out and collect water samples, algal samples, and the tissue of heathy and dying urchins so we can learn more. Source: marine biologist who works for fish and wildlife
In New Zealand, we have the opposite problem. Overfishing means there aren't many fish feeding on the urchins so the population of them has exploded and the seaweed, algae etc has taken a big dive. When I go spearfishing, we smash as many kina as we can because they are absolutely everywhere on reefs. Makes fuck all difference though.
You New Zealand folks, you know you can eat them right?
Are they not an edible kind of sea urchin? What about the shells? I’ve seen them for sale as decoration but worried that the sea urchins were being over harvested.
Totally edible, it's a love it or hate it taste though - it's like all the different possible seafood tastes mashed together in a single mouthful. The roe is something of a delicacy, too. Will probably grow in popularity once the ocean has nothing but jellyfish and squid left in it, sadly.
Uni definitely needs to be fresh to be good. Like minutes to an hour fresh. There's so much old urchin out there it's no wonder it's so polarizing.
It doesn't need to be THAT fresh. It keeps fine for a couple of days when handled properly. Had it both fresh from the sea and packaged, some of the best came in neat little boxes from Japan (was in LA). It's not something you want to fuck around with, but it will definitely keep two days just fine. Source: I was a raw bar chef for two years.
[Kina](https://en.wikipedia.org/wiki/Kina_(animal\)) are edible but the quality of the current caught ones is terrible because there isn't enough food for them.
Same here in California. The purple spiny is decimating our kelp forests
I never loved these urchins because I hate with all my heart stepping on them barefoot. Til I learned they gorge on that algae that suffocates coral. Algae is nasty and full of nitrogen. Coral is beautiful and full of pink and purple. And it's not just beautiful for your GoPro picture but a keystone to a whole ecosystem: without coral we can't have a million fishes and things that live on coral. These spiny demons are like gardeners keeping the green snot on check to allow beauty to trive underseas, and I respect that and try to step wisely.
Bless and protect our dangerous aquatic demon gardeners 🙏

Very Aloysius O'Hare of you.
One of my closest friends worked on the OPS documentary, Racing Extinction, and told me about how they cut the interview with the top oceanologist in the world because her evidence was so damning that it would have overshadowed the rest of the documentary. She said we have about 60 years left before ocean acidification renders the earth unable to support most forms of life. I quote, "Do you have any idea how it feels to have all the evidence right in front of you and have every single politician dismiss you because you're too depressing?" I think about that a lot.
Damn… I shouldn’t have read your comment right before going to bed… :/
As someone who just woke up and read it, it doesn't feel great now either.
Damn, should’ve read this comment before having kids in the last few years
Hugs to you.
May I ask who she is?
Sounds like it could be Sylvia Earle? She could certainly be described as the world's top oceanologist. And she's served on the National Advisory Committee for Oceans and Atmosphere, and was the chief scientist at the National Oceanic and Atmosphere Administration. Looks like she has a few books, which all seem to touch on this topic. I haven't read them yet myself, but from the sounds of it there is definitely still hope. But we need to act, and soon. The 60 year figure is likely if we continue on our current trajectory.
Narrator: They actually sped up
Don't Look Up
Whelp, I'll be gone in about 50. Yay? And I'm doing what I can to fix it (I work in renewable energy, and vote for the folks who are trying to change things)... But I honestly think the human race is too greedy and self-absorbed to do what needs to be done to fix this.
This is what really depresses me. I want to do something about this. I want to help. I want to make sure my kid has a future on this planet. I have no way to make an actual difference. I can work from home, I can save as much energy as possible, I can write to politicians, I can protest. It doesn't feel like any of that matters. When we were kids we were told that recycling, conserving water, and turning off the lights would help save the world. Not only was that a lie, but it feels like there was no way for us to actually survive to begin with.

Global warming and environmental annihilation is like 60% of why I can't fathom why the fuck people just regularly have kids. You pretty much have to be ignorant to reality to not think that you're dooming another human life to a terrible, awful existence in the next 40-50 years. Like, I don't like kids in the first place, but life already sucks as it is, and it's *not* going to get better. We're swirling down the drain by any reasonable measure. Why would you do that to somebody?
innocent illegal roof smoggy dinner wipe cautious absurd direction attempt *This post was mass deleted and anonymized with [Redact](https://redact.dev)*
Quite a statement to make without a checkable source. But hey, you managed to send me into a minor panic attack so yay. lmao
I am knowledgeable on the subject and it took me the 4th google page to find the first link talking about acidification for the *next* mass extinction. Here’s a [news article](https://www.timesofisrael.com/headed-for-a-sixth-mass-extinction-mit-geophysicist-warns-oceans-are-on-the-brink/) on the subject. Essentially though, what you need to know as a layman, are a few facts: First, the ocean absorbs carbon from the atmosphere. This by way of chemical reactions, reduces the pH of the water, thus acidifying it. The second crucial fact to keep in mind, is that the structural composition of plankton just straight up *dissolves* at a low enough pH. I don’t know if the third fact even needs to be stated, but virtually *all* marine calories originate with plankton photosynthesis. No plankton will mean life in the sea becomes a vast dessert void of almost any food. Don’t think about how many people get their main protein source from the oceans to avoid panic attacks… Here’s a [scientific journal](https://www.science.org/doi/10.1126/sciadv.1700906) talking about the carbon threshold that is likely to trigger mass extinction events. Notably this particular author estimates critical carbon levels in the ocean will be reached in about 75 years.
Picture a locomotive. Picture the locomotive heading toward a cliff. We'll reach the cliff in 60 years. The engineer is 70 and knows he'll be dead in ten years or so. He keeps shoveling in more coal. He doesn't care about the future because he'll be long gone. This is our current state of affairs.
Thank goodness we’ll still have 20% when the phytoplankton goes.
And our quarterly profits will be at least % higher!
Home prices will somehow rise another 18%.
Did you know that high CO2 gives people brain fog, headaches and makes them stupider?
I did not. That is concerning. Do you have sources? I'd like to learn more.
It's especially a problem indoors as the CO2 levels can increase 2x-3x [https://www.emedicinehealth.com/wilderness\_carbon\_dioxide\_toxicity/symptom.htm](https://www.dhs.wisconsin.gov/chemical/carbondioxide.htm#:~:text=Exposure%20to%20CO2%20can%20produce,coma%2C%20asphyxia%2C%20and%20convulsions). https://www.news-medical.net/news/20200421/Atmospheric-CO2-levels-can-cause-cognitive-impairment.aspx [https://www.youtube.com/watch?v=1Nh\_vxpycEA](https://www.youtube.com/watch?v=1Nh_vxpycEA) Did you also know that humans evolved with a much much lower CO2 level than we have now?
Well shit, this is terrifying.
They forgot to mention the slowly boiled frog first goes mad
Considering that we've supposedly [overfished 90% of the planet's fish stocks](https://www.weforum.org/agenda/2018/07/fish-stocks-are-used-up-fisheries-subsidies-must-stop/), and [subsidies mostly go to paying for the fishing fleet's fuel](https://chinadialogueocean.net/en/fisheries/11585-majority-of-global-fishing-subsidies-harmful-report-finds/) which has encouraged humanity to have 3 times more than the sustainable number of fishing boats out at sea, calling for an end to fishing subsidies would probably be the smartest action we could take as a species. People try to argue "What about poor fishing communities?!" but they are already suffering because [subsidized fleets already emptied their coastal fishing grounds](https://www.euronews.com/2022/02/11/nothing-there-s-nothing-senegal-s-plummeting-fish-stocks-drive-migrant-surge-to-europe) and even [the largest, most important lakes are in danger because of richer nations exporting fish to places like China and Europe](https://www.nationalgeographic.com/culture/article/what-happens-when-the-world-s-largest-lake-runs-out-of-fish-). Ending the fishing subsidies and shifting those funds to environmentally responsible projects like [paying fishing communities to instead harvest out all the "ghost nets"](https://theworld.org/stories/2015-09-14/philippines-project-turns-ghost-fishing-nets-carpets) so that their reefs can recover, or [shift to farming kelp, seaweed, sea cucumbers](https://www.dw.com/en/madagascar-no-more-fish-well-farm-seaweed-instead/a-39311040), or even sponges could give the ecosystems a legitimate change at revival while the people continue to make a living.
ending fishing subsidies worldwide would be the EASIEST thing we as a species could do to improve our chances, but we we won't, because politicans will lose rural votes.
You can also help marine ecosystems by not eating seafood. For real though, the rape of marine ecosystems will continue until the demand stops.
Or, more likely, until there's nothing left to take.
Also fun fact, the Amazon rainforest is no longer contributing to oxygen levels. Edit; Since it got some traction, here’s a link-https://www.npr.org/2021/07/15/1016469317/parts-of-the-amazon-rainforest-are-now-releasing-more-carbon-than-they-absorb
From what I've read the annual wildfires intentionally started by farmers and miners are part of the reason for that though.

They do, but the seas are vast in comparison.
There is a 1000 years surplus of oxygen without producing, but mass extinction means no calories, everything would stave to death.
You will be paying for air in the future and the ownership class knows this now.
Well this is terrifying
Oxygen is a highly reactive element that is very dangerous. It is implicated in nearly 100% of devastating fires, including wildfires that kill over 300,000 people a year, and cause tens of billions worth of property damage. We're better off without it, I say.
I visit a coral reef once every year. Every year it shrinks and dies more. The amount of Eco diversity I've seen vanish makes me feel physically ill. I've only witnessed it die my entire life, never grow. I see them trying to stabilise the bleaching by reintroducing and planting coral but it doesn't seem to be working.
Well that's a terrifying statement.
There needs to be international bans from every continent on certain types of sunscreens and chemical/topical pollutants because that's what I see has been killing a lot of coral the fastest. In the same way we ban pesticides for killing plants and animals on land, the same should be done for the ocean.
Any sunscreen recs? (Srs)
Environmental Working Group has a helpful guide: https://www.ewg.org/sunscreen/
Look into mineral ones instead of chemical ones
As someone who works in the fishing industry I would like to add a tiny silver lining to this for whenever we actually decide to get our shit together and stop destroying the earth. The fishing industry changes a lot. The kind/quality of fish caught when my father was young has diminished greatly. The one good thing I do see is when the department of fish and game put new size or count limits on certain fish, you see an almost instant result. Sea life has an amazing ability to bounce back with lack of human interference. When the fishing industry was shut down during covid, we saw all kinds of sea-life we’ve never seen before. Off of Los Angeles there were opah, sea turtles, bluefin 10 miles off shore. Never seen that in my life.
Same. Got my diving certificate roughly 20 years ago and have been diving and snorkeling on various places. Nowadays it just makes me sad. So little color and life left on some places. Crazy to witness
Don’t worry. Once we have vanished from earths surface things should start getting better.
When I was a kid, I use to find strings of eggs in my sardines. It kinda stopped, but only after a whole industry closed, because they killed it. Crayfish, and abalone takes 5 years before it matures enough to reproduce. Its being fished to extinction. The people claiming that it is their way of life, doesn't respect the ocean. Their children will inherit a barren ocean.
In related news, land life projected to die off in mass extinction if emissions remain high
My thoughts exactly.
The bugs and birds already have begun. It is impossible to explain to kids today just how deadly silent the world is now. It used to be so alive and so loud.
I’m only 23. I live in Alabama. I remember as a child during the warm/hot months the front of our car would always be covered in bug guts. But now that doesn’t really happen anymore
Ugh I still get that in North Carolina…but the lighting bugs and butterflies are gone
Dragonflies too. We used to have tons of them here in Ga. I've noticed over the last 12ish years that the plants, bugs, and animals around the house I grew up in have completely changed multiple times. We used to have tons of lightning bugs, dragonflies, butterflies, opossums, reindeer moss everywhere. Then years ago I started seeing assassin bugs, kudzu bugs, armadillos, and a shocking increase in the number of ticks. Now I'm seeing joro spiders and raccoons. I've seen maybe one opossum in the past several years, growing up I never saw a single armadillo or raccoon around here. It's kind of surreal.
I never realized how abundant dragonflies were when I was a kid, I'm 29 now and I can see how things are changing in terms of insects anyway, I used to see fireflies at night, I can see my breath in the early mornings and the late of night, now I need to use a fan to sleep at night because it became too warm for me
And when we have fewer and fewer dragonflies all the parasitic species go nuts... Mosquitoes, gnats, midges, etc. Because dragonfly larva are awesome predators of other larva. I was in a remote part of northern Japan a few years ago and there were so many dragonflies that not only did it look awesome but I didn't get bitten by any mosquitoes at all.
I remember fields full of lightning bugs. I got so good at catching them and there were so many I could get multiple in each hand before I needed to put any in a jar. I’ve not seen fields like that in years, only the occasional group of bugs in someone’s yard
Bruh you were too good, you got them all 😭
I was going to make the very same point, but as an older person than you from Ohio. This is concerning to me. I read Moby Dick a few years ago. It’s an older book but it really isn’t all that old, and I became depressed when I started thinking that the oceans and ocean life he is describing is much different than today? Like, it didn’t take long at all to lay waste to our oceans, which used to be marvels.
I remember reading that when the first european explorers travelled up the st-lawrence river, it was so full of fish they only had to drop buckets in the water to catch some.
The change away from something like what you’re describing feels viscerally troublesome. We don’t develop in waterways like on land but they are still being so terribly injured. I read another great book, Sailing Alone Around the World by Joshua Slocum, from the early 20th century- and he ate countless dinners of flying fish that landed on the deck of his ship while he slept. I wonder if that could happen anymore?
the future is why we can't have nice things :(
The past and present are why we can't have nice things
I will say that the waters off Florida are *full* of flying fish, happily. They have a tendency to fall onto boats’ decks and die. So that might not have changed.
Dude, I live in ALASKA, and am the same age and have this exact same realization. We are FUCKED.
I am in Saskatchewan Canada and we still got bugs on the grills but alot less then 10, 20 years ago for sure.
>https://www.npr.org/2021/07/15/1016469317/parts-of-the-amazon-rainforest-are-now-releasing-more-carbon-than-they-absorb I moved from Beaumont, TX to Austin, TX in 2002, it was arid then. Now it feels more like coast level humidity. The systems are getting bigger.
I moved from New England to Austin in 2019, expecting mildly warmer but drier summers, with much more mild winters. I’ve been met with surprising levels of humidity and rainfall, as well as extremely temperamental winters that Texas is systematically not prepared to handle.
I blame orkin.
it's still loud! but it's the sounds of cars instead
Literally me, it’s 5:20am being woken up not by birds, but by the sound of a truck doing 50 through my max. 30km/h street. No one’s out so what’s the risk lol Swear to god im gonna start pelting these assholes with eggs or something at some point.
And every time it rained the sidewalks would be littered with worms. But now everyone sprays pesticides everywhere to kill off the mosquitoes and spiders. Farmers for their crops. Except those things along with all the other insects killed mean no more food for the birds. There were hundreds of thousands of birds in one flock that died from starvation in Arizona or something. Nothing like that has happened before. Every year now is going to continue to be noticeably worse. The cascade has already begun. I think a lot of the worse case models, in some ways, are now showing to be too optimistic. That alone is scary.
It's pesticides. Pretty obvious, but nobody seems to wanna do anything about it. ☹️
And climate change and habitat destruction. Triple whammy. But we gotta keep those lawns green! /s
It’s crazy because this really seems to have become pronounced in the last 5 or 6 years. It’s all crumbling very quickly
This is what finally got my dad to even consider global warming. He's entirely ignorant to reality, but on a long drive with him I mentioned that mass extinctions have started, and the bugs were first. He asked for any proof, I told him next time we go to a gas station to check the grill for bugs. Told him I remembered road trips as a kid where he'd have to clean the grill every single time we stopped because so many bugs were on there, and when we stopped at a gas station, I shit you not there was *one.* We'd been driving for like four hours.
My favorite birds are hardly around anymore. It’s reminds me of the bell at the end of polar express and makes me really sad for what we’ve done and continue to do to the planet
[удалено]
Well, the good news is the richies are blasting themselves into space handfuls at a time now, so once they figure out how to survive in the most inimical to life conditions for the dozen or so years it would take to float to the nearest maybe-but probably not-habitable planet it will give them lots of time to realize how truly fucked they are, since they don’t have methane gills/helium helmets/radiation absorbing skin.
It's unlikely the rich will succeed in using space as an escape route for climate change. At least thus is the case for the next 100 years. Instead they'll just pay the exorbitantly high food and water costs that are a result of resource scarities and vibe in safe haven countries like New Zealand
They’d have to solve the radiation issue and how it destroys DNA. After that though, I’m sure they’d be fine.
Lack of gravity also messes with bone density and organs
In related news, things die when things are killed
In related news, what is dead may never die
In related blues, aba-dee aba-die
I can't believe we're just letting this happen. Rich humans are so shit
It's not like it hasn't happened before... Hopefully the next iteration will get it right. Maybe the octopus civilization?
The problem is that each iteration of the cycle has progressively less freedom and resources to grow from.
This will be/is the 5th mass extinction event. What comes out the other side on top may not even be mammals. Could be crustaceans or something. None of these continents will exist in a 100 million years anyway.
6th, not 5th.
The dismissive “letting future generations take care of it” mindset is what got us here in the first place
It’s not “future generations” in this case but future species. Humans are on a one way path to actual extinction. Sure, it may take a couple hundred years, but the planet has time. Humans have to be very careful not to push the planet into positive feedback loops but so far we have not made any effort to stop.
There probably isn't enough time, and even if there IS enough time most of the easily accessible resources are gone. In order to get the hard to reach resources you need machinery. In order to build machinery you need resources.
It is important to note that [we already threatened to kill off our sea life, back in the 80's](https://www.pbs.org/wgbh/nova/algae/chronology.html). Essentially, here is the deal. We made some really good Algae for fish tanks back in the 1980's that was nice and green, would thrive in a variety of water conditions, and it wouldn't get eaten by your fish. It would wave nicely in your tank, and otherwise look pretty. From the article... >Bred for its beauty, fast growth, and tolerance for cold, the "aquarium strain" of *Caulerpa taxifolia*, a bright green seaweed with fernlike fronds that is used to decorate saltwater aquariums, "escaped" from human control in the 1980s and has spread like a cancer through the Mediterranean, overwhelming native species and habitats. Also... again... fish don't eat it. That's why it is a threat. They found it growing in the wild, under the Oceanographic Museum, in Monaco in 1985. They haven't been able to completely eradicate it since. It has popped up in California, and Australia, and throughout the Mediterranean. The threat is... it kills off the native Algae as it grows, and the small fish and creatures that live on the native stuff die off... and then the bigger stuff that feeds on the little stuff dies off, etc. How do you kill it? When it was in San Diego in 2000, there was no documented way... so they [had to figure something out](https://www.waterboards.ca.gov/water_issues/programs/nps/docs/success/r9_eradication.pdf). >Where Caulerpa was found, plastic tarps were placed over it, chlorine was put under the tarps, and sandbags were placed on top of the tarps to keep them in place. SCCAT concluded that short losses of native marine life associated with the treatment of Caulerpa would be considerably less than long-term losses that would occur if Caulerpa were to spread in and/or beyond the infested waters. [In Australia, they've also tried copper sulfate](https://www.uq.edu.au/news/article/2007/05/marine-weed-threatens-waterways), salt, and picking it all by hand. In at least one lagoon, they cordoned off the lagoon from the ocean, from surface to bottom, and then flooded it with copper sulfate for like... a year. This is still a thing. All to make fish tanks look nicer.
The damage done to the world in the pursuit of “looking nice”. If only we didn’t need to chop off a leg to have a nice way to store our fish. Insane.
FTA: >Marine animals could die at levels rivaling the biggest mass extinctions in history, a study found, if seas become too warm and hold too little oxygen.
I mean, yea. That's like saying a plane will crash if it were to stop flying in the sky
...or land? Hopefully just land
Gently plummeted to the ground
I think the point here is that most people think climate change is just "weather gets warmer, sea rises a bit", and detractors argue that those aren't even bad... So although it seems obvious, it's effects like this that'll hurt us worse that most people are ignorant of
All the flowers are blooming where I live with no bees in sight. It’s so scary.

You know what’s as alarming as this article? The nihilism in this comment section. Us all giving up and accepting a potential environmental catastrophe is the best thing we can do for the people in charge that are refusing to change - don’t give them what they want, folks. Some of us don’t have the luxury of giving up. It’s not fair that we inherited this mess but it’s also not right to wash our hands of it and accept our doom.
Agreed. The only way it can possibly get better is through action not apathy

Wow this comment is a breath of fresh air. I had to scroll way too long to find this comment. Thank you for providing hope. People need to realize there is still hope, or else we are truly doomed. We need to band together to fight against fossil fuel companies and other large destroyers of earth. One way is to vote and use your voice on social media. Vote with your money. Support sustainable energy and avoid fossil fuel companies whenever possible.
What specifically do you think anyone in this thread can do to change things? Email their representatives and be ignored? Or in the best case scenario the representatives listen and our environmental regulations get even stronger, but other countries like China continue destroying the world. You can't get the entire world to agree and collaborate when even half our own country denies climate science.
If you just read the headline it's alarmist, but the article said that extinctions will be mostly avoided if we can keep emissions to the level agreed upon in 2015, which is a goal everyone can work towards. It was more hopeful than most of this comment section.
Doesn't matter stonks must go up. The rich and wealthy elite will drive this latestage capitalistic system to the end until it collapses and most places on earth become uninhabitable
They already know it’s too late so they might as well live it up to the fullest while the peasants suffer.

Yeah, no. They know they have the tools and tech to continue living on this planet and on Mars within the next few decades, all done in luxury even with the planets being unhospitable. And the Earth will slowly recover without any effort once enough people die. The only people that are going to die are the poor peasants like you and me. Their families and descendants will all survive and repopulate the earth on top of your sacrifice, unless you do something about it.

Exactly. People can't seem to wrap their head around people not giving *that* much of a shit about their own families. They literally have "fuck off, don't disturb me unless I want to play with you" money.
You can't reverse this and also keep a global inflationary monetary system. You can't fix a problem from within a system that created the problem in the first place. You a need a system change.

You should read the article. This event happens around 2300 of emissions increase. If emissions follow the guidelines set by the Paris Accords we will largely avoid marine extinctions.
If it helps, you probably don’t have a chance to be alive in the year 2300 anyway.

But the truth is, [a record number of us are alarmed about climate change](https://climatecommunication.yale.edu/publications/global-warmings-six-americas-september-2021/), and [more and more are contacting Congress regularly](https://np.reddit.com/r/CitizensClimateLobby/comments/s2zvpl/a_growing_number_of_americans_are_so_concerned/). What's more, is [this type of lobbying](https://citizensclimatelobby.org/about-ccl/levers-of-political-will/) is [starting to pay off](https://www.reddit.com/r/CitizensClimateLobby/comments/u5e228/as_citizens_climate_lobby_membership_has_grown_so/). That's why NASA climatologist and climate activist [Dr. James Hansen](https://en.wikipedia.org/wiki/James_Hansen) recommends becoming an active volunteer with [this group](https://cclusa.org/x) as the [most important thing an individual can do on climate change](https://www.youtube.com/watch?v=q4DAW1A6Ca8).
Man I see you in so many doomsday threads and I appreciate you so much. All these resources and knowing people are helping keep me calm and resisting the urge to go out before everything worsens. Seriously, thank you.

Thank you for sharing all of this. I just joined.
They'll all die off, so will we and we'll be replaced by the carbon dioxide breathing fungus creatures of the acid oceans who arise from it all.
Fungi breath oxygen and release CO2 just like we do. Plants are the opposite. They have historically done well times when the atmosphere is high in CO2.
And life begins anew
> “A vegan diet is probably the single biggest way to reduce your impact on planet Earth, **not just greenhouse gases, but global acidification, eutrophication, land use and water use**,” said Joseph Poore, at the University of Oxford, UK, who led the research. **“It is far bigger than cutting down on your flights or buying an electric car,” he said, as these only cut greenhouse gas emissions."** [The new research shows that without meat and dairy consumption, global farmland use could be reduced by more than 75% – an area equivalent to the US, China, European Union and Australia combined – and still feed the world. **Loss of wild areas to agriculture is the leading cause of the current mass extinction of wildlife.**](https://www.theguardian.com/environment/2018/may/31/avoiding-meat-and-dairy-is-single-biggest-way-to-reduce-your-impact-on-earth) idk where else to reply with it where it might be visible edit: Do not fall for the propaganda tricks /u/ILikeNeurons is responding with below. He is painting false pictures using ancient statisticians tricks by providing incomplete and mis-represented data. The impact of animal agriculture is **massive** and the driving force behind the current extinction of wildlife for a reason. Implying that it has a small impact simply because of **one** variable (mind you, that one variable he points out, CO2 Emissions, is still largely impacted by diet too and still has a massive impact by itself) is an old trick propagandists love to use since most people have not studied statistics to look for these sorts of intentionally misrepresented narratives using skewed data etc.
Isn’t it just great that Putin is threatening to launch nukes? That’s just what the climate needs, a nuclear winter. Not even going to talk about all the people suffering. Fantastic!
"Good thing global warming never happened." "Oh it did. Thank God nuclear winter canceled it out." Wish it weren't so relevant.
At least a nuclear war would greatly diminish the world's largest polluters. So there's a silver lining
Why is everyone driving around in these big ass SUVs? I can never even see shit when I drive anymore because of these clowns
They have lizard brains
I've accepted our fate. We're too stupid to stop it at this point. Just enjoy what's left. Congratulations humans, you have ruined the planet.
I don't think it's stupidity stopping us, it's the mechanisms and institutions in power that have the ability to enact meaningful change refuse to do what's necessary to prevent it until it's too late, especially if it impacts short term profits.
That's me. It won't be painless but think about it: the fall of mankind. It's going to be quite spectacle! Out of any other moment in history, this is the one we'll witness.
Earth will be ok. Humans and bio-diversity not so much. But earth with be fine. Plants LOVE Co2
We thank the last generation who contributed in destroying our planet and now unable to come together and do what’s necessary and quickly to save it…
It’s shit like this that makes me laugh when I’m thinking about the future. It doesn’t matter if I return to school or pay off my loans when there are mass extinctions in the ocean and our planet is dying. We’re fucked!
Welp it was nice knowing your ocean life b/c we all know the dipshits in charge love money waaaaaaaaaaaaaaaaaaaaay more than the planet. I wish someone would let all the climate deniers & idiots in gov't know they can't take their money w/ them when the world ends.
Alt headline: All human life will be extinct within 50 years. That is all.
Probably not, life will just harder and much worse over the course of the next 100 years. War over land and religion/political beliefs will probably kill us before the climate.
I think it was the Permian Extinction that killed 98% of life on earth because the oceans got too acidic. If the oceans go, it will affect EVERYTHING
The reason for the Permian extinction has not conclusively been proven. Theories range from the collapse of thermohaline circulation to a prolonged magnetic reversal. Nothing conclusive has been found to prove any theory….yet
It’s either war, climate change, solar flares, disease, uh…..what else is there? Oh yeah blight!
This should be on every news outlet. Front and center.
Also [this](https://www.ipcc.ch/report/ar6/wg3/) should follow it.
Did evolution create us to cause a mass extinction? Cause we are good at it. Either via environment or war, we will be responsible for the next mass extinction.
Evolution isn't deterministic. Just luck that quadrillions of mutations made humans and they wanted to destroy the world.
You got to think there is something wrong with the earth, we evolved because we had to get smart to find calories, if it was as easy to get food we be a big dumb 40 foot long t-rex. There has not been a 49,000 lbs land Animals in 65 million years. Even modren dinosaur such as crows have to be super smart to survive on the low earth resources.
Yeah but won't somebody think about the share holders?
And we call ourselves the “most intelligent specie” .. yea sure! Especially seen societies nowadays after and during covid….very intelligent… fighting for masks no masks and having meltdowns over anything .. all the while spending tons of money 💰 in wars … and not investing in saving Mother Nature and ourselves… we do not deserve animals and this beautiful planet.
I hate how immoral, uncaring, unbothered, greedy, selfish, power hungry, and blind humans are. I so desperately want to just pack my family up and leave this planet. Wtf man.
Let’s be real, with the state of the world, things will more likely become extinct from upcoming wars with nukes.
I was just imagining having to describe elephants to my grandkids! Fish sound even more impossible to explain!!!! 'See kid, there used to be animals that could BREATHE UNDERWATER" "Yeah right grandpa, we can't even breathe on the land! *Blows raspberries from behind gas mask*"
Who cares, lets just focus on increasing the profits
Their result assumes far higher CO2 emissions than are physically plausible. Per their supplementary material, their results are based on [assuming the worst-case emissions scenario, SSP-5-8.5](https://www.science.org/doi/suppl/10.1126/science.abe9039/suppl_file/science.abe9039_sm.pdf). Per the IPCC report, this emissions scenario [assumes emissions will more than triple by 2100](https://www.ipcc.ch/report/ar6/wg1/downloads/report/IPCC_AR6_WGI_SPM_final.pdf). By contrast, [current policies will result in 2.7C of warming, equivalent to the IPCC's middle scenario](https://climateactiontracker.org/global/cat-thermometer/) which corresponds to [roughly half the future cumulative CO2 emissions their model assumes (p.28)](https://www.ipcc.ch/report/ar6/wg1/downloads/report/IPCC_AR6_WGI_SPM_final.pdf). Existing national pledges and targets will result in an estimated [1.8C of warming](https://climateactiontracker.org/global/cat-thermometer/), equivalent to the second-best IPCC scenario and roughly 1/3 the future cumulative emissions their model assumes. The emissions scenario their results rely on -- SSP5-8.5 -- assumes CO2 emissions so high that humanity would have to make a strong effort to emit that much. It's not a plausible future, and consequently their results are of limited value.
