Ocean Temperature
- RecycledEle 3y agoIf someone did present evidence that they oceans were not warming, they would be shouted down. Therefore, the claim the oceans are warming is not falsifiable. Therefore there can be no scientific position taken on whether the oceans are warming or not. I regret that both sides in the warming debate have proven they will fake data. Their actions make it impossible for me to know if our planet is warming.
- jackhab 3y agoCan someone explain me why people post links to Wikipedia articles without any context?
- stefncb 3y agoThey maybe stumbled upon it and found it interesting. There's often no need for context, it can simply be an interesting article to read.
- prawn 3y agoI've submitted them before and often enjoy when they're posted. Sometimes the zeitgeist-link is obvious or sometimes it's a bit random. I'd guess that people who enjoy when they're posted also take to submitting interesting pages they've read (or re-encountered).
- moehm 3y agoYou may enjoy this little list I built, which collects all Wikipedia articles posted on HN and rank and tag them. https://www.mostdiscussed.com/ https://www.mostdiscussed.com/
- hyperpape 3y agoOcean temperatures have been the subject of a half dozen HN articles (driven by articles in the news) in the past few weeks, so I assume that’s the reason. Speaking for myself, not Dan, but for non-technical topics that appear on HN, the discussion would be a lot better if the average commentator read the obvious Wikipedia article before commenting. That’s true even though Wikipedia has a lot of problems.
- hutzlibu 3y ago" but for non-technical topics that appear on HN, the discussion would be a lot better if the average commentator read the obvious Wikipedia article before commenting. That’s true even though Wikipedia has a lot of problems" I have vague ideas of a forum, where any new poster has to answer some basic questions about the topic first correctly. Most online discussions would probably benefit from that.
- arc-in-space 3y agoFor the exact same reason people post links to other things, it's interesting. It's always been more "hacker" than "news" here. Incidentally, check out this wacky alien-looking worm that exhibits bioluminescence even though it lives its entire life inside of a tube, so there is no one to perceive it: https://en.wikipedia.org/wiki/Chaetopterus https://en.wikipedia.org/wiki/Chaetopterus
- dmbche 3y agoOh shit - cool worm!! Edit: Keep being weirded out that comments like this get downvoted. What's the point?
- joshuahedlund 3y agoHN is not Reddit. We like comments that add information and dislike comments that only express brief reactions, jokes, etc. Keeps the signal to noise ratio high.
- dmbche 3y agoThanks!
- stevenwoo 3y agoThat was neat, though it does mention there are some other creatures that can choose to share the tube and the research about it may be lacking in smaller companion life (bacteria or other lifeforms).
- ezconnect 3y agoIs this worm all over the world or there's a certain climate it can live on. Wikipedia doesn't expand on it.
- avgcorrection 3y agoIt’s a delightful HN quirk. You can post a direct link to anything you find interesting, apropos of nothing.
- kzrdude 3y agoOcean temperatures have been in the news (for me), so I for one can see the context.
- melenaboija 3y agoBecause it is compliant with HN rules. If you see it in the front page and it bothers you enough to ask the question maybe you should try to find another community.

- haizhung 3y agoNot sure if my math is correct, but seems like compared to before global warming started, the oceans now hold an excess of energy that is equivalent to running a nuclear power plant for 3 million years. This is now excess energy in our system. I just wanted to share that since I couldn’t really relate to the 10^22 joules number in the article.
- thret 3y agoWhich article are you referring to? I didn't see it in the parent.

- gary_0 3y agoShort of launching all the nukes, it's actually really hard to imagine a faster way to make Earth uninhabitable than humanity's GHG emissions project. (3.68×10^13 kg of CO2 in 2022 alone! Impressive!) If we could terraform planets as quickly as we're de-terraforming Earth, Mars would be prime real estate in no time. Alas.
- wcoenen 3y ago> hard to imagine a faster way to make Earth uninhabitable Manufacturing lots of SF6 (sulphur hexafluoride) might do the trick. 22800x more greenhouse potential than CO2 per unit mass.

- ricardobayes 3y agoWhat's the reason it started to skyrocket after 1980 and not before? What made it stagnant or even slightly drop between 1940 and 1980?
- notamy 3y ago> What made it stagnant or even slightly drop between 1940 and 1980? Well, there was that one really big war in the 1940s...
- jonhohle 3y agoDoesn’t that suggest sea transportation may be a bigger contributor than greenhouse gasses? Industrial production was at its limits during that period, but I would imagine cross ocean cargo was down significantly. It would be interesting to see what pandemic years looked like with thousands of ships sitting for months off shore. Edit: there might be something to that idea - https://arctic.noaa.gov/Report-Card/Report-Card-2022/ArtMID/8054/ArticleID/988/Sea-Surface-Temperature#:~:text=Highlights,observed%20in%20the%20Chukchi%20Sea https://arctic.noaa.gov/Report-Card/Report-Card-2022/ArtMID/.... maybe globalism is the issue. One more edit: container ships are effectively giant heat sinks with a ton (literally tons) of surface area (corrugated containers), sucking heat from the air and dumping it into the ocean. If that hypothesis has merit, I would expect the LA ports to have an increase in temperature during that same period.
- f6v 3y agoOr there’s a complex interaction between Earth’s natural climate change and greenhouse gas emissions.
- jonhohle 3y agoThat’s definitely possible, but complexity makes errors more likely. According to Google^TM, it takes 20-200 years for CO2 in the air to dissolve in the oceans and yet there are immediate effects during WW2 and COVID.

- f6v 3y agoWhat concerns me is sloppy writing of this article. For example: > In other words: the climb in ocean temperatures is the inevitable outcome of Earth's energy imbalance, primarily associated with increasing concentrations of greenhouse gases.[8] The reference leads to https://doi.org/10.1007%2Fs00376-023-2385-2 https://doi.org/10.1007%2Fs00376-023-2385-2 which is an article that doesn’t establish the causal relationship between human emissions and rising temperatures. Rather, the authors use this as an opening and reference other works on the topic. If you put a reference to back up your claim, the reference should be to a primary study and not some study that references other study that might be relevant.
- jfengel 3y agoOh, you may be looking for this. It dates back before the doi system, so I don't think it has a link there. https://www.geographyrealm.com/wp-content/uploads/2019/11/1856-foote_sunsrays_247-248.pdf https://www.geographyrealm.com/wp-content/uploads/2019/11/18... “Circumstances affecting the heat of the sun’s rays”, pp 382-83 in: The American Journal of Science and Arts, Second Series, Vol. XXII — November, 1856 (Whole Volume).

- f6v 3y agoI forgot Wikipedia has nothing to do with science.
- brabel 3y ago> These predictions suggest ocean temperatures of 55–85 °C during the period of 2,000 to 3,500 million years ago, followed by cooling to more mild temperatures of between 10 and 40 °C by 1,000 million years ago. Imagine going to the beach and finding the water temperature is 85C, near boiling :D. What a different world that would be.
- skymast 3y agoWhat is the temperature of the oceans supposed to be?
- upsidesinclude 3y ago> between the 1950s and the 1980s, the temperature of the Antarctic Southern Ocean rose by 0.17 °C (0.31 °F), nearly twice the rate of the global ocean. >The warming rate varies with depth: at a depth of a thousand metres the warming occurs at a rate of nearly 0.4 °C per century (data from 1981 to 2019), whereas warming occurs at only half that depth [sic] So from 20% of two centruries we have developed a long term average? The chart of excess ocean energy also relates the current ocean energy relative to an average which ends in 2006. If you're unaware this biases the end values upwards. Calculating out their 2020 value to each kg of ocean water on earth for a depth of 700m gives 0.189Cal. In other words, less than 20% of one degree above an arbitrary average calculated on a century basis with 80% of the century data absent. If this could just pretend to appear as science i would start to care.
