Ship spies largest underwater eruption ever
- cakeface 7y agoUnderwater volcanoes are responsible for climate change. Prove me wrong.
- lohszvu 7y agoThere are many factors in climate change. Some more impactful than others
- werdnapk 7y agoHumans are responsible for climate change. Prove me wrong.
- scohesc 7y agoNot responsible, but "contributing to". It's a natural process of the earth, but I don't deny we're rapidly accelerating it out of control.
- rayvd 7y agoThe sun and natural variables in the incredibly complex climate system are FAR larger factors. Prove me wrong.
- abtinf 7y agoYour claim is that before humans, Earth's climate was static?
- littlestymaar 7y agoUnderwater volcanoes cause autism and vaccines cause climate change. Prove me wrong.
- tajd 7y agoEveryone who gets vaccinated dies. Prove me wrong.
- googlemike 7y agoYou, and opinions stated as facts by ignorant people are exactly what is wrong with the internet. I used to think everyone having a voice was a wonderful, liberating new freedom for the whole world. The last few years have really changed my mind.
- scohesc 7y agoThat's really depressing that you think that way. That way of thinking is pretty dangerous. I know it's a "slippery slope", but thinking that certain people shouldn't express their opinions on things in a public place goes against everything the internet gave us so many years ago.
- mwfunk 7y agoEveryone has a right to their own opinion, no one has a right to their own facts though. I get what you're saying but there are consequences to certain types of misinformation (ex.: anti-vaxxers). It's a complicated issue.

- LeifCarrotson 7y agoI think we're in a state of transition that will take a few decades to resolve itself. In the past, it was difficult to get an idea published. Money and power are definitely not sufficient to show that someone's ideas should be listened to (in some cases, the converse is true), but they're at least weakly correlated to competence. Also, when the barrier to entry was higher, less was produced, so there was a lot more opportunity for coversight. This lead to printed words and popular speech having an air of authority and truthfulness. I expect that this will be swiftly eroded, and replaced with more caution, as society adjusts.
- scohesc 7y agoIf you take away the right for anti-vaxxers (or climate change deniers in the OP's case) to talk about things on a public platform where they're actively ridiculed, they're going to go underground and create their own communities under the radar. Say someone goes to that community to try and convince them otherwise and says "hang on, vaccines don't cause autism, here's some research articles", they'll get banned and their post removed, and everyone in the separate community is none the wiser and nobody who uses that community will ever have the chance to be convinced otherwise. So if you really wanted to stamp out the anti-vaxxers, I guess you'd have to have some kind of monitoring to make sure they don't post anything anywhere about anti-vaxx views. That would need to be done by someone or something powerful, say... Facebook or the government? I don't trust Facebook as their ulterior motive is selling your data for sweet sweet ad money, and I don't trust the government as many governments have shown in the past many times they can't be trusted to regulate speech of citizens (not that I would EVER want to regular speech) So - why not just let them speak on large public platforms and have them get laughed at?
- Mc_Big_G 7y agoIt's hilarious that someone can look at the data about man-made CO2 emissions and still be a denier. WTF
- MeltySmelty 7y agoIt's hilarious that someone can look at the data about man-made CO2 emissions and still be a believer. WTF
- s_dev 7y agoThe onus is on the person making the claim to bring evidence to the discussion. "What can be asserted without evidence can be dismissd without evidence" -- C. Hitchens Since the comment was removed or deleted it originally said something like "Underwater volcanoes are the cause of Climate Change -- prove me wrong"
- GalacticDomin8r 7y agoPerhaps the only thing more absurd that original is censoring it and removing it.
- AnimalMuppet 7y agoIt's not removed. Turn "showdead" on in your profile.
- Spare_account 7y agoLow quality comments are removed when flagged by enough people. It's actually a good thing.
- GalacticDomin8r 7y agoYou are free to have that opinion. I won't try to suppress dissent.
- toss1 7y agoI find that the Venn diagram of <dissent> vs <evidence-free assertions, disruption, distraction, and disingenuous arguments> do not overlap, and it is useful to distinguish between the two and to treat them differently. To paraphrase Asimov, one person's ignorance (deliberate or not) is not equal to another's knowledge.
- koube 7y agoSince the question has been asked, I found this to be relatively convincing to the casual observer: https://www.bloomberg.com/graphics/2015-whats-warming-the-world/ https://www.bloomberg.com/graphics/2015-whats-warming-the-wo...

- mhh__ 7y agoWhy the correlation with CO2 levels then?
- dang 7y agoCould you please not start shitty subthreads by posting flamebait to this site? https://news.ycombinator.com/newsguidelines.html https://news.ycombinator.com/newsguidelines.html
- ohashi 7y agoIt's interesting to read an article and come to HN hoping to find more interesting comments only to find one thread with stupid memes. Is this the largest ever because we're just starting to be able to map this type of stuff or have we seen a lot of them and this is enormous?
- deleted 7y ago[deleted]
- Gibbon1 7y agoWell there is this, "The map of the sea floor, made by the ship’s multibeam sonar, indicates that as much as 5 cubic kilometers of magma erupted onto the sea floor." I think 5 km^3 is a large eruption by any standards. Looking at lists of modern ones it's a index 6 event which happen every few decades on land. From the article it sounds like if it weren't close to Mayotte it wouldn't have been picked up seismically.
- volkk 7y agois this too deep for a tsunami effect? can underwater volcanoes cause tsunamis?
- cobbzilla 7y agoThe article says it’s too deep to cause a tsunami, at least where the quakes are now. If seismic activity starts moving towards land and a big quake is close enough, a shelf-collapse could cause one.
- foota 7y agoThat would be scary, seeing as I believe the largest tsunami ever was created via a similar mechanism. Edit: not the largest, but large. See: https://en.m.wikipedia.org/wiki/Storegga_Slide https://en.m.wikipedia.org/wiki/Storegga_Slide
- everybodyknows 7y ago... gas trapped inside the black volcanic material. Sudden release of such gases has been suspected in the case of a number of sudden ship disappearances over the centuries. If a bubble's volume is large relative to the ship's, the ship will drop to the bottom as the gas forces water from under the hull. Then the surrounding seas crash onto the decks.
- richjdsmith 7y agoThere is a no-sail zone quite near the coast of Grenada due to an active underwater volcano. The volcano is called Kick 'em Jenny and has sunk numerous boats over the years. On one instance it sunk a boat and killed 60 people.
- gus_massa 7y agoWikipedia link for the lazy https://en.wikipedia.org/wiki/Kick_%27em_Jenny#Maritime_exclusion_zone https://en.wikipedia.org/wiki/Kick_%27em_Jenny#Maritime_excl... The part about the "sinking hazard" has a [citation needed] anyway. The Spanish version look more concerned about eruptions than bubbles, and says that when they detect unusual activity the radius is increased from 1 mile to 3 miles.
- anigbrowl 7y agoWell that about wraps up the Bermuda Triangle for me
- theoh 7y agoBubbles that large are not stable—the sinking effect (which is disputed) would have to do with a significant reduction in density of the water by a large number of smaller bubbles.
- aristophenes 7y agoTry to picture this. All the water next to a ship mysteriously flowing away from the ship, over the bubble while the ship for some reason is the only thing going down through it. Water is also heavier than air, and water on top of a bubble will also fall into the center of the bubble (breaking it up into smaller bubbles), until the surface tension of the water around the bubble is great enough to hold it together (small bubble). Therefore a huge bubble gets split into many bubbles, I suppose at depth a lot of the gas gets dissolved into the water. The worst that would happen is many small bubbles cause the density of the water to decrease, causing the boat to sink lower into the water. I'm not sure if the water could lose enough density to sink a regular boat directly? I think what you may be thinking of is large, shallow explosions (generally man made) under a ship which create a temporary bubble which then collapses in on itself, but can cause extreme stress on large ships. Extremely contrived example of bubbles being able to sink a small boat: https://www.youtube.com/watch?v=MSmAXp_BHcQ https://www.youtube.com/watch?v=MSmAXp_BHcQ How a bubble generated by an explosion can actually sink a large ship: https://youtu.be/UdFNuc5XtII?t=192 https://youtu.be/UdFNuc5XtII?t=192
- orpheline 7y agoI read that headline as "Ship spies largest underwear eruption ever" I can't even say where my mind went, 'cause it hasn't come back yet... Fridays are hard. Especially on mobile screens.
