Warm Water Squid Reported Off Alaskan Coast 44

fenris_23 writes "The associated press is reporting Humboldt Squid - a species that lives in the warm waters off the Baja coast - have recently been observed off the coast of Alaska. 'A large Humboldt squid caught offshore from Sitka is among numerous sightings of a species seen for the first time in waters of the Far North, and the first of the species recovered from British Columbia waters.' This may help corroborate a similar slashdot story covering rising CO2 levels measured at the Mauna Loa Observatory where the possibility was raised that rising sea temperatures are reducing the Earth's ability to manage greenhouse gases."

    Migration of individual animals and species due to changes in the climate isn't a new thing. The earth is not static, it evolves and has cycles, so it's a long shot (not to say junk science) to claim it corroborates theories on a specific cause of those climate changes.

    It's still moderately interesting but how come this is considered a bigger science story than this [slashdot.org]?

    Is /. really that broken?

      Yes, climate "evolves and has cycles". But those "cycles" don't just happen by themselves, they are caused by changes in the environment, atmosphere, radiation, etc. Currently, it evolves in the direction of getting warmer, and that is something that deserves a scientific explanation.

      It just happens that CO2 levels are a highly plausible explanation of it. If you have a specific other explanation, please share it with us. Right now, your alternative theory seems to be "shit happens", and that really is junk science.

      You don't need PCA in order to see trends in that data, you can use your own eyes. On the other hand, even if done correctly, PCA is probably a bogus procedure for this kind of analysis. So, you have a stupid response to a stupid analysis. Frankly, even observing a single warm water squid in cold water tells you more.
      • I haven't said that the cycles happen by themselves, of course there are chains of causalities (both manmade and natural). Neither that its just "shit happens". I don't know where you got those things from but stop putting words in the mouths of people you consider your opponents, it's better to actually try to see what they say.

        As for PCA's validity etc. you don't seem to be too preoccupied by science being done right, did you read the link and the links in that text or did you just gloss over it?

          No, you didn't say that, you simply ignored the question of causation at all. We currently have one plausible hypothesis for why global warming is happening. When you come up with an alternative, please share it.

          The article about PCA isn't about a flaw in the data, it's about a flaw in one particular statistical analysis.
          • you simply ignored the question of causation at all

            I did no such thing, I put forward an important news item that has big implications for most of the theories about what the specific cause(s) is/are. For you to automatically interpret that as a claim that there are no causes at all is ludicrous. The news isn't about what the specific causes are, the news is about a major and often used analysis of data being critically flawed.

              In case you still do not realize it the analysis of said data is the starting point for the majority of science on global warming, and used as scientific proof for it

              The paper in question has indeed been cited over 300 times, so it is important, but it contains several results. We don't now which of those results (if any) citing papers rely on and if the conclusions of those papers would be affected if the McIntyre and McKitrick criticism is accurate. Muller fails to make that analysis in his paper, and

        Here's another plausible expanation, from the Oregon Institute of Science and Medicine [oism.org]. The gist is that long term measurements of solar activity (going back thousands of years) show that the sun's output varies in cycles, and that those cycles coorelate very closely with average temperature measurements over the same period.

        This seems much more plausible to me, since it explains global warming and cooling that we know occurred well before the industrial revolution.

    • i dont completely follow what environmentalists are claiming. appearing animals living usually in warm area is a strange thing. but its wrong to connect immediately and directly with the results from the global warming what environmentalists insist. current global warming has got many other causes than human activities. lets reconsider from astronomical geological point of view. i think science can have room for it.

    Off Brittany coast, around the Belle-Ile-en-Mer island, (latitude around 47.3, that's upper North than New-York or even Boston) now live tropical fishes. They've established there a couple years ago.

    The sea there has been warming these last years. I'd say on average it went up 2 C in temperature, but that's a totally unscientific estimate of mine.

    • "in linking sundry phenomenon as part of a poorly understood hypothesis"

      One of the key determinants of the range of a species is temperature. So, observing changes in the range of species is one way in which one can determine whether there have been long-term changes in temperature.

      Or it may not be, we just don't know. The way to gain more certainty is to get more data from different sources than w

    About a month or two ago, some fishermen off the coast of Alaska found a penguin. This is the first record of a penguin in the Northern Hemisphere. The fishermen hauled in their nets and there he was! The species was identified as a Humboldt Penguin. These penguins live at the southern tip of Chile and Argentina, about 8,000 to 9,000 miles away from home.

    This has nothing to do with global warming- and almost everything to do with a weather phenomenon caused by reversal of currents in the Pacific. In an El Nino year- these sightings are quite common (tropical fish off the coast of Oregon and Washington, warm water species in the Gulf of Alaska, etc). It's easy to see why- a reversal of currents means instead of cold water coming south from the poles, warm water is headed north from the equator. (the other side of the big convection current is off the coast of Japan- where El Nino years mean you get different species of sushi on your plate).
    • i think this comment is fairly true. i didnt know exactly the influence and effect of el nino here off coast in japan. but this year unusually one-tenth of the normal years quantity of anchovy( iwashi-in japanease) and aboundant quantity of sanma (i dont know how to say in english...) are reported. this theory tells us clearly the exact cause of this phenomenon which certainly brings about changes in cuisines.
      • Sanma is Salmon in English. They don't like warm water as well- and they're very common in the United States and Canada as a food fish source. The reversal of the standard Pacific Current would bring them down from Alaska to you in Japan.
