#72I hope you like jellyfish.
Can humans eat jellyfish? Maybe part of the solution is to shift overfishing to the jellyfish population.
They can be a bit like rubbery noodles if they're not thoroughly dried, or crispy like shredded cabbage if they are. I don't know if the edible ones don't sting or they do something to neutralize the stingers. (Jellyfish stingers are spring loaded and generally work quite well whether the jellyfish is alive or not.)

I find it incredibly sad it has made the top post. The article does not link to any peer review studies to prove it's point, which to me means it's probably bunk, taking a know issue and enlarging it to sensationalise. And it's sad people fall for this.
With a little bit of research on your own you can find out for yourself that this is an incredibly important issue that affects everyone on the planet, and there is nothing "sensational" about the way it is reported.
Yet you seriously haven't included any links to this easy to find research the we are at an all time acidification high in 300 million years?
Pretty sure the title might actually get it right unlike the actual article "Ocean acidification due to carbon emissions is at highest for 300m years"
It is the rate of acidification, not the acidification itself that is high.

They seem very in favor reducing over-fishing, switching to clean energy sources, etc. They're only in favor of geoengineering if politicians can't get their shit together and we end up on the brink of a disaster. "We do not promote the use of the [geoengineering] method highlighted in this section. We merely present it here as an interesting solution proposed by the field of geoengineering, a popularly growing disci…
The symptoms are all we care about, why would anyone give a shit about CO2 levels if it didn't cause global warming? It's not like it's toxic. If it's cheaper to geoengineer the CO2 away, why not?
Fossil fuels are not a long-term energy solution in any case, so it makes more sense to attack the problem from that angle.
And I suspect the answer is that it's not cheaper. I'm unaware of any cheap, scalable, safe method of reducing CO2 levels. It's difficult to conceive of a practical solution to global warming that doesn't involve drastically reducing the ongoing CO2 output. How are you going to balance out 30+ billion tonnes of carbon dioxide per year?

Your right in the sense that there is nothing catastrophic from a the perspective of geological time. There have been mass extinctions before. The problem is that we would like to continue living in an environment similar to what we evolved in, and we would like to continue to have large amounts of bio-diversity and biological services available on a timeline that is useful to us. There is nothing particularly magica…

I'm adept of the view that the environment influences the organisms as much as organisms influence their environment, or rather that there isn't a clear distinction between envi…
"Events like increased CO2 levels in the ocean should be seen as the way things are, rather than one-off catastrophes."
This is a false dichotomy. Just because these events have happened regularly, on geological time scales, doesn't mean that it wouldn't be a one-off catastrophe from the point of view of homo sapiens. I'm not saying an extinction event, but it could be a catastrophic event.
In other words, taking the long view here (as you're doing) is way too abstract in this case. There will be real costs to change of this magnitude.

#77While I recognise this question might be abrasive, I feel compelled to ask it. Why does this belong on Hacker News? This isn't technology. This isn't legal news (i.e. software patents). This is in no way related to Hacker News. I have no problem with interesting articles being upvoted, but I feel we need a place to put these or a tagging system similar to lobsters.
>This is in no way related to Hacker News
The vast majority of "show HN: my new disruptive pseudo-plagiarized wheel-reinventing RESTful scalable .js + go single-page site framework" or "_insert_valley_startup_here_ plans to revolutionize _trivial_consumer_SaaS_niche_" posts have little to do with actual hacking, either. Few complain about those.
Here we have a post that points out a massive systemic problem we're facing as a species for which we have no current solution. Pretty sure we're in hacker territory. Much more so than in the case of the Yet-Another-Web-Framework or Disruptive-Instagram-For- Squirrels crap we normally get on the front page.

Fake science for the masses
Older article on the issue -
"The coming centuries may see more ocean acidification than the past 300 million years."
https://pangea.stanford.edu/research/Oceans/GES205/Caldeira_...
It seems to me, 300 million is used a lot since it's the period scientists can measure?
Probably it's gotten caught up in some sort of quote that we are heading to a time where it's higher than 300 million.
It wasn't hard to intuitively know the article is dodgy, it jumped between acidification, to pollution, to over fishing, not really related topics.

what you're looking for is: https://en.wikipedia.org/wiki/Lotka%E2%80%93Volterra_equatio... A predator-prey model is essentially never just a stable population for both. Instead, you go through periods of increasing prey -> increasing predators -> decreasing prey -> decreasing predators. Here the prey would be atmospheric carbon dioxide and the predators would be the plankton.
So atmospheric carbon breeds?
Its an anlogy, not a syllogism. It would seem enought that Co2 may be correlated with breeding. Which may or may not be technically correct, but its at least a coherent thought.

Well ocean acidification is real and proven. At this point all we're arguing about is how many years we have left.
This is certainly true, but amount matters. If its 300 years then we have a problem, if its 3000, maybe not so much. Articles like this do not help give perspective.
