Glaciers have always grown and receded

This is just one of dozens of responses to common climate change denial arguments, which can all be found at How to Talk to a Climate Sceptic.


Objection:

A few glaciers receding today is not proof of Global Warming, glaciers have grown and receded differently in many times and places.

Answer:

Firstly, it is more than “a few glaciers” that are receding, it is a pervasive, sustained and accelerating global trend.  The National Snow and Ice Data Centre (NSIDC) maintains a chart of global glacier mass balance, and for as far back as their data allows us to look, all but a few years have shown a loss in ice volume of subpolar and mountain glaciers.  Further, annual losses are increasing.

But no one claims that melting glaciers are proof of Global Warming. Proof is a mathematical concept. In climate science one needs to look at the balance of evidence and in that light, the above data is just one piece of evidence that is consistent with Global Warming.

So what do we find if we look to the other aspects of the cryosphere?.  It turns out what we find is lots more evidence that is indicative of world wide and sustained temperature increases:

And of course, this is all consistent with all the other evidence of warming that there is out there. Clearly we are dealing with much more than a few receding glaciers.

  1. Nice graph. Too bad you’re cheating. Why not show the full data? Back to the 1700s? Our current retreat is nothing new in the context of the past two hundred years or so. The trend simply continues. So much for the big bad humans doing it.

  3. Coby, that was the point, you are drawing a massive conclusion from a tiny shred of data. Bad. Unless someone can show evidence that glaciers do not retreat without interference this is not evidence of anything.

    As for me I believe this planet experienced an ice age, and all those glaciers retreated. Man had nothing to do with it; the planet is better off for it. Also true that some small villages rely on melting glaciers for their precious water. Melting glaciers is therefore good. If they retreat a lot then some villages have to move. Oh, well, they must have done that before, so here goes again.

  7. Coby you consistently miss the point that the sea level 18,000 years ago was 400 feet below where it is today! With no human input, the sea level came to its present level (but for about 2-3 feet) about 3000 years ago.

    In other words, the sea level is about where it was 30,000 years ago, before the last ice age. Earth cooled, with no human input, then it warmed with no human input.

  11. I don’t know but is that even the issue?

    As I understand it the problem of Greenland’s ice retreat is not the prospect of it all being gone but a whole *lot* of it being gone and the resultant effects on sea levels and the positive feedback of less snow reflecting sunlight back to space. Also Greenland’s ice sheet retreat is a gauge of where we are. I mean, Jesus, its melting. Regardless of where we stand on the overall AGW hypothesis, does anyone dispute it?

  12. Skip, thanks for your reply.

    I guess my question is “is there an issue”? 100 Gigatons sounds awfully impresive, however –

    100 Gigatons of ice melting is about 0.00452632% of the total Greenland ice sheet, which will put the sea levels up about 0.0003546 of a metre. (Someone please verify my figures).

    And the reduced reflectiveness of this small difference – does it amount to anything?

  13. Those numbers sound about right – for the recent melt rate. Changing units, that’s 0.35 mm/y. Current annual sea level rise is almost 10 times that (about 3mm/y) but more than half is from the expansion of warming water, the rest is from Greenland, Antarctica and other glaciers around the world.

    Here’s the trouble with 0.3 mm/y from Greenland. A mere decade ago it was basically 0. See http://www.skepticalscience.com/Why-is-Greenlands-ice-loss-accelerating.html (particularly the second graph). That’s an accelerating loss. It’s accelerating for probably two reasons: (1) It’s still getting warmer (2) Greenland is a hollow basin, ringed by mountain ranges, filled with ice. As the outlet glaciers retreat, the area exposed to warming ocean water increases, so the basal melt rate increases, with positive feedback.

    So, while I certainly can’t guarantee it, the mass loss rate of Greenland could double in another decade, double again in the decade after that, etc. until leveling off at a rate that would melt the whole thing in ~500 years. That would contribute over 1m/century. A slightly different accelerating dynamic is affecting the West Antarctic Ice Sheet. Taking all sources into account, we are likely looking at 1.4m sea level rise by 2100, with 2-3m/century for several centuries after that. That’s if we don’t get our act together on mitigation.

    1.4 meters is huge. It doesn’t seem that big if you live near a rocky shore, or don’t live near a shore at all, but the first 1 meter of sea level rise will wipe out half the agriculture in Bangladesh, and have similar effects on other low coastlines around the world. The population of Bangladesh is 160 million.

  15. gsp,

    As a former teacher I think I can make understand the missing connection between daily experience and largely intangible scientific theory. And I think analogy, at the risk of creating new misunderstandings, can clear things up very well.

    Without taking time to look up specific figures, here are two things I’m confident can be said about our world that bear some resemblance to the situation you’re describing:

    (1) The value of the stock market is on a long-term upward trend. This is regardless of the fact that there have been huge momentary dips and dives, like this most recent recession and the years-long Great Depression. Living in that moment, it’s easy to assume that now is different, that the long-term trend isn’t still heading up, but any economist will tell you this will all recover and go back to that gradual upward slope as it did after the Great Depression and every other market slump.

    (2) The population of the earth is on a long-term upward trend. There is at least one point in history when the population decreased markedly over a period of a few decades: The Plague. Living in this time it would be easy to assume that everyone was going to die and the world would end. But on the whole, since thousands of years ago, the population is still rising. The long-term trend is still upward.

    Regarding climate change, then: scientists almost completely agree that until this last decade there has been a decades-long warming trend. They largely agree that this recent leveling-off of the trend is just one of those dips and dives, and that it will soon continue upward. They largely agree that if it continues that way, it will eventually have a profound negative effect on our ecosystem, which would affect our own habitat, health, food supply, land use, economy, and practically every other element of our lives. And they *generally* agree, with confidence (but not certainty), that man’s activity has some measurable effect on this.

    Therefore, the best guess is that it’s worth our effort to take strong steps to lessen our contribution to the long-term warming trend.

    A cold day or even year in one city, state, or even the whole globe, is just a blip on the radar. Scientists believe the forces driving temperatures slowly upward are still at work.

    How’s that, gsp?

    Keywords that often get lost in the debate and the media’s coverage of it: “generally agree,” “not certain,” “believe.” The scientific facts and measurements may be (at least mostly) accurate, but the theory based around them is just a theory. There’s simply enough evidence to make *most* scientists *pretty* sure that it’s the right one.

  17. I wonder what National Geographic explorer Eddie Kisfaludy would have reporter if he could have flew his helicopter over Glacier Bay back when Captain George Vancouver found Icy Strait, at the south end of Glacier Bay, choked with ice in 1794?
    Coby Beck; Don’t you think that glaciers would be retreating after the LIA ended?
    This applies to your dire warnings regarding melting glaciers. Keep in mind that Geo. Vancouver’s ships were wind powered; therefore, he wasn’t spewing out any diesel smoke to start this massive retreat of these glaciers.
    “The explorer Captain George Vancouver found Icy Strait, at the south end of Glacier Bay, choked with ice in 1794. Glacier Bay itself was almost entirely iced over. In 1879 naturalist John Muir found that the ice had retreated almost all the way up the bay. By 1916 the Grand Pacific Glacier was at the head of Tarr Inlet about 65 miles from Glacier Bay’s mouth. This is the fastest documented glacier retreat ever. Scientists are hoping to learn how glacial activity relates to climate changes and global warming from these retreating giants.

    Glacier Bay was first surveyed in detail in 1794 by a team from the H.M.S. Discovery, captained by George Vancouver. At the time the survey produced showed a mere indentation in the shoreline. That massive glacier was more than 4,000 feet thick in places, up to 20 miles wide, and extended more than 100 miles to the St. Elias mountain range.

    By 1879, however, naturalist John Muir discovered that the ice had retreated more than 30 miles forming an actual bay. By 1916, the Grand Pacific Glacier – the main glacier credited with carving the bay – had melted back 60 miles to the head of what is now Tarr Inlet.

But I also wonder what some report would mean if the reports of hundreds of people in the same field for thousands of glaciers rather than one field can be ignored by idiots like yourself. If the reports of hundreds can be ignored, then one definitely can, and be done so hundreds of times more rationally.

      But rationality doesn’t matter to AGW deniers, does it. It just gets in the way of ideology.

  18. Hi John,

    I have to point out up front that the original post above is pretty much spot on as an answer to your question, which stripped of snark is pretty thin gruel. You are pitting the record of one glacier one hundred years ago to challenge the significance of the current “pervasive, sustained and accelerating global trend” (see above original post). You are also wanting to ignore the context of other changes in the cryosphere and global climate indicators.

    Much of your quoted material does not appear in the links you provide, and in fact the second is completely unrelated,but I am not interested in disputing the accuracy of the statements. I will note that you are silent on what has happened to that particular glacier since. Is it still retreating? Is the global temperature still just “recovering” from the Little Ice Age even as it rises to levels not seen since at least 5000 years ago? To understand global and modern trends you really need global and modern data.

        PS He was right too: there’s chaos now because we don’t know how to deal with snow. See your asshole country for a recent example. He did predict that. But your echo chamber did not bother to add that in, so you aren’t talking from your own knowledge, only your indoctrination.

  25. Potholer54 has a series with tony heller in a fact check. tony started with a long laundry list of problems potholer got “wrong” and it took two episodes to get it down to just one he still insists (appeal to authority, which requires appealing to the authority that claims the appeal to authority is a fallacy for it to be fallacious, making its incorrect use, as tony and every denier does, self defeating: they can’t cite the appeal to authority as a fallacy because to do so requires using that fallacy).

    He still insists he doesn’t get feedbacks greater than 1, though. And I do put the blame at potholer for this, however, even though he’s using the same argument and logic as climatologists use, cribbed from mathematics field experts, because his explanation is against the wrong point.

    Heller ignorantly insists that if CO2’s effect is 1c/doubling and that feedbacks increase that to 3.5c/doubling, this means a feedback of 2.5, greater than one. And potholer et al’s explanation is how heat loss means that there is no runaway effect.

    WRONG.

    Heller is wrong. It IS NOT 2.5 (or 3.5, depending on how you define it) feedback, as can be seen by simple junior school maths: the sum of an infinite series.

    sum of the series 1/r^n where n goes from 1 to infinity is what feedback is, when heller and all other deniers who follow this “argument” are complaining.

    The sum is 1/(1-r). Which goes to infinity if r=1, the limit of a converging series being less than 1.

    However, if the feedback figure (r) is 0.5, then the sum to infinity is 2, if r=0.75 then the sum to infinity is 4.

    So to get a sum to infinity (the steady state of a feedback loop a la op amp theory) of 3.5 when you input a 1 you need a feedback parameter, r, of between 0.5 and 0.75.

    Therefore definitely less than 1.

    If the input is 1, you get the sum of 1/(1-r), if the input is 2, you get twice the answer, three times, three times the sum, any value other than 1 as the starting (no feedback) value, V, will make the sum V/(1-r). And require a value for r below 1.

    And feedback for the climate, since CO2 is the driver (CO2e, for a real earth climate) and the feedbacks include feedbacks for more of the greenhouse gasses as well as any other thing that changes because of the former change, is between 0.5 and 0.75.

    Below the 1 value heller and his fellow ignorants insist is the maximum.

    Potholer’s problem is he doesn’t think heller is dumb enough to get this badly wrong. In that potholer is wrong too.

    1. Wow!

      Keep clinging to it, mate!!

      Cling to the AGW HOAX for as long as you can!

      The “evidence” for AGW depends entirely on computer model extrapolations.
      You are kidding yourself!

      Please post all the evidence you have that shows the current climate condition is somehow outside the range of natural variations?
      Please show all the evidence you have that does NOT rely solely on computer model predictions.

      You’re an excellent example of the type of person who is ALWAYS fooled by political bullshit.
      I am convinced that your mind is very firmly closed to new information.

      At least then it was “up for debate”.

      Anti-AGW science is settled.
      Settled science.
      The science says you’ve fallen for utter bullshit.
      I feel comfortable with that assessment of your intellect and political beliefs.

      I would even go so far as to say that you have utterly NO WAY of defending the AGW crap with logic and reasoned thought.

      You have been fooled by this bullshit for at least ten fucking years!
      I don’t think you’ll ever realise that its bullshit.

  26. Denieridiot says “YES!

    You have to pay politicians to work out the taxes and laws and apportion police to the duties. Do you think that police do all the lawmaking and budgeting along with the collection of taxes and apportionment?

    If you do claim to want to pay police because they make the community safer, you’re paying politicians to make your community safer. They do the paying of police and making the laws for the police to, well, police.

      And yet again you’ve proven that you are willing to pay politicians to improve law and order. Because if you did not then you would not be so desperate to deflect away from my post regarding the police.

      You pay the police and politicians because you “want” law and order (for your needs, you HATE it when they keep the stricture of the law that impacts on you: you’re perenially whining about how the police are after “law abiding” drivers rather than the drug dealers), so your petulant demand about paying politicians to combat climate change is pure idiot screams.

      But trump is in deep shit and you no longer feel like you’re going to get “your” voice heard in power any more. So you’re back here screaming at an empty room and try to ensure that you do not ever get countered in your insane rants.

        (I knew it long ago, as you would remember.

        You see, about ten years ago, having been reading AFTIC for a few months, I had an Ephiny.
        I realised that every single believer in AGW was ‘of the left’.
        All the regular commenters (you’ll remember there were HEAPS of believers back then) who believed in the hypothesis known as AGW were leftists.
        It was an important moment for me as a proud Conservative.
        I realised that leftist thinkers (like you) are very easily fooled and led by the elite establishment.

        I was kinda alarmed when I first saw An Inconvenient Truth in 2007.
        I wanted to learn more and I became a devout scientific sceptic at a particular moment.

        I realised that the geological record is the TRUE evidence of climate change,

        WOW, it impresses me that you re STILL clinging so desperately to this fucking HOAX.

        I gotta give you credit for your closed-mindedness.
        Full marks for having decided you already know everything, and STICKING to it for so long!

        (the BEST president of all time)

        I love that you support the murder of babies because you pretend to be “PRO-CHOICE!”

        I love that you support “racial diversity quotas”, just like the KKK did,
        I love the fact that if you were American, you would DEFINITELY be a democrat.

        The MAIN thing, wow is that you will NEVER come up with actual measured data to support your foolish faith in the UN politicians.
        Gimme evidence from weather balloons.
        Gimme evidence from satellites.
        show me how measured data proves that the current climate is outside natural variations.

        Just now, it occurs to me that we’ve had satellite temperature data for around 30 years now, haven’t we?
        You say it’s settled science…

        But just think; in 300 years time, we will STILL only have 330 years worth of satellite data.
        The earth’s climate changes in far longer time-scales than that.
        Surely you’re aware of that?
        You understand this of course, but leftist politics is FAR more important to you than science.
