Animals 'Shapeshifting' in Response To Climate Crisis, Research Finds (theguardian.com) 54

Animals are increasingly "shapeshifting" because of the climate crisis, researchers have said. From a report: Warm-blooded animals are changing their physiology to adapt to a hotter climate, the scientists found. This includes getting larger beaks, legs and ears to better regulate their body temperature. When animals overheat, birds use their beaks and mammals use their ears to disperse the warmth. Some creatures in warmer climates have historically evolved to have larger beaks or ears to get rid of heat more easily. These differences are becoming more pronounced as the climate warms. If animals fail to control their body temperature, they can overheat and die. Beaks, which are not covered by feathers and therefore not insulated, are a site of significant heat exchange, as are ears, tails and legs in mammals if not covered by fur.

The review, published in the journal Trends in Ecology & Evolution, found that the differences are particularly pronounced in birds. The author of the study, Sara Ryding of Deakin university, a bird researcher, said: "Shapeshifting does not mean that animals are coping with climate change and that all is fine. "It just means they are evolving to survive it -- but we're not sure what the other ecological consequences of these changes are, or indeed that all species are capable of changing and surviving." While the scientists say it is difficult to pinpoint climate breakdown as the sole cause of the shapeshifting, it is what the instances studied have in common across geographical regions and across a diverse array of species. Examples include several species of Australian parrot that have shown a 4-10% increase in bill size since 1871, positively correlated with the summer temperature each year.

    Have you seen what a middle-aged man looked like in the 1960s?

    28 inch waistline with skinny legs and no belly.

    How about now? More like 38 inch waist, flabby legs and potbelly.

    Will this help us survive the coming food shortages?

    • I know all the cannibals are thankful.

    • You may be trying to make a stupid joke. However our environment does have a big deal of influence on how we look like.

      While I don't propose that we should go Vegan or even Vegetarian, Americans tend to eat more meat than what we really need, so we are given a lot of protein in our diets which does add to our bulk. Also how much of our diet consists of a lot of extra carbs and simple sugars too creates that beer belly.

      A lot of these changes during our development has created permanent changes to our body.

      • People do eat too much protein but only because they eat too much food.

        Unfortunately rice, wheat, potatoes, oats, and corn are cheap and the people who buy them from the farmers heavily fund research to support their very high margin products. Many doctors have rejected the ideas from that research at this point but despite that a 'heart healthy' diet from a cardiologist today looks little different than it did in the 90s.

    Though experiments in the Climate science are understandably hard (if not outright impossible) to conduct — because of the scales involved — given the discipline's 50+ age, by now, there's got to be some successful prediction they made.

    Hence the challenge: cite two such predictions. The rules:

    Each entry must consist of a pair of links
    One link to the prediction being made, the other — to the confirmation of it coming true later, within, say 20% of the predicted value(s), if quantifiable.
    The linked-to publications comprising an entry must be at least five years apart.
    Predicting tomorrow's weather does not count. Nor does cherry-picking of successful prediction for an article published only, when the prediction succeeds (survirorship bias [wikipedia.org]).
    The prediction has to be meaningful — and falsifiable.
    Predicting, that temperature may rise or fall, for example, will not count.
    The theory or hypothesis behind the successful prediction must not have other, failed ones, behind it.
    A standing clock is right twice a day — if it is wrong the rest of the time, we don't want to rely on it.

    Listings of failed predictions [cei.org] are easy to find — which is normal for any science. Can you offer some successes?

        I think, that's because you cannot... There are no such predictions.

It's because of such protestation that I stepped outside of the global warming debate and bring up the issue of seeking solutions.

      Another problem with the global warming panic is ignoring that there is a cost to doing everything to lower CO2 emissions, a

      How are you distinguishing between predictions that were, or at least might have been, correct at the time, but didn't come to pass because of actions that were taken in response to those predictions (chemical poisoning, acid rain, ozone depletion, etc), those that were hyperbolic but may yet come to pass, and those which were flat out wrong?

      The page you link to seems to have, with no apparent sense of irony, conflated them all to further a specific narrative.

        I'm not distinguishing.

          Because I have already made a number [slashdot.org] of predictions [slashdot.org] on this site during the past ~10 years. They are publicly available. I could also have linked to predictions about the (then) future release of methane clathrates as global temperatures rose, with a corresponding link to later surveys showing the process underway - but that would have taken more effort finding them than I was prepared to expend on feeding the troll.

          I have simply reached the conclusion that some people, e.g. those who would uncritically pos

            That seems like "sour grapes". You don't need to persuade me — this is not a private conversation, but a public forum. You'll persuade others. If you can, that is...

    Yep, I got it, global warming is bad and it's largely from people burning fossil fuels. Can we get more articles on solutions?

    There's a lot of good news out there on people finding solutions to global warming. I see it every day on other sites. Is nobody interested?

    Oh, right, we can't talk about solutions here. That's because the solutions involve energy sources that are so bad we can't dare mention their name or risk being moderated down, being accused of being a shill, and have insults throw our way. We can't even take the time to reflect on the gains we've made in lowering CO2 in the recent past.

    Nope, we can only discuss how bad things are getting, and not even think how things can get better.

  • US kids whose grandparents fled the totalitarian regime of communist Viet Nam in the 1970s, are significantly taller than their genetically indistinguishable ancestors.
    Is that "shapeshifting" or "evolving"?

    • The height increase is probably due to all the growth hormone US farmers feed their livestock being passed up the food chain.

      • Or it's people getting enough nutrition that their physical development is not stunted. But sure, go ahead and think it's the hormones if you like, that's more tasty beef for me.

        • Both are probably in play. Not that it's particularly germaine, but I eat beef. I'm careful about where I get it, though. I should also mention that although growth hormone is allowed in beef in Canada (though it's not in the sources I use), it is NOT allowed in chicken or pork.

    • That's the difference between generations with various levels of malnutrition and those raised with sufficient nutritious food.
      There's now an average of 3" in height difference between North and South Korea.
      It's due to North Korea's food shortages and poor quality of much of that same food.

      Since WW2, Japan has had average heights increasing as well since their food distribution and quality of nutrition has greatly improved.

      It's been studied and is pretty clearly documented, poor quality nutrition and lack o
      • That was exactly my point. Creatures getting longer noses or beaks or feet or whatever, compared to a few decades ago, is not anywhere close to being an example of "evolution" nor even "shapeshifting to deal with the stress of Climate Crisis".
