Trying to explain New Zealand’s ‘unusual’ growing glaciers

Contrary to all of the hype about melting glaciers, at least 58 New Zealand glaciers advanced between 1983 and 2008. Indeed, Franz Josef Glacier advanced nearly continuously during those years.

According to scientists from Victoria University of Wellington and the National Institute of Water and Atmospheric Research (NIWA), at least 58 New Zealand glaciers advanced between 1983 and 2008.

But how can glaciers be advancing in a world that’s (supposedly) burning up?

“Glaciers advancing is very unusual—especially in this period when the vast majority of glaciers worldwide shrank in size as a result of our warming world,” said lead-author Associate Professor Andrew Mackintosh from Victoria’s Antarctic Research Centre.

Why are the glaciers advancing?

“We found that lower temperature caused the glaciers to advance, rather than increased precipitation as previously thought. These periods of reduced temperature affected the entire New Zealand region, and they were significant enough for the glaciers to re-advance in spite of human-induced climate change.”

“Periods of reduced temperature.” What a wonderfully Orwellian way of describing cold weather.

Computer models come to the rescue

How could the researchers explain away the “periods of reduced temperature?” By diving into their computer models, of course.

“It may seem unusual—this regional cooling during a period of overall global warming,” said associate Professor Mackintosh, “but it’s still consistent with human-induced climate change.”

And there you have it.

Computer models now show that both “reduced temperature” and, what shall we call it – negative cooling? – are caused by humans.

The study was published on 15 Feb 2017 in scientific journal Nature Communications.

Franz Josef Glacier exhibits a cyclic pattern of advance and retreat, seemingly regardless of human activity. It advanced rapidly during the Little Ice Age, reaching a maximum in the early eighteenth century. It retreated several kilometers (miles) between the 1940s and 1980s, but also advanced intermittingly during those years. It advanced from 1946 to 1951, it advanced from 1965 to 1967, it advanced from 1983 to 1999, and it advanced yet again from 2004 to 2008.

At times, Franz Josef Glacier has advanced at the incredible rate of 70 cm (more than 2 feet) per day. Two feet per day!

  1. “Why are the glaciers advancing?” you ask, well I foresee AGW numbeciles will work up computer model ‘proving’ the mountains are growing.

    • Actually, the Mt Cook region is being pushed up at nearly a metre a century but erosion is almost as great. In the summer of ’91 ~30m collapsed off the peak of Cook and ended up spread over the Tasman Glacier way below.

    Comment:
    Which you would expect with the GSMs: Oort, Wolf, Spoorer, Maunder and Dalton 1790 to 1835 and the period Gleissberg period 1890 to 1940, after that you are in the High Output period of the Solar Warm period which ended in 2008.

    The later advances since 1940 may well be at the bottom of cycles during periods of Meridional Jet Stream activity caused by low levels EUV being absorbed by the atmosphere.
    However, when looking at this Graph for La Nena events
    Notice during low periods of EUV and this Modern GSM the number of La Nena events increase, SC20 is a particular case in point.

  3. I too was encouraged by this study, however I can confirm that since 2008 the Franz Josef Glacier has receded. Probably a few hundred meters. I saw this with my own eyes a few months back.

  4. I think the point I wanted to make was that here in NZ the retreating glaciers were constantly used as an example of AGW. Now when they advance its an anomaly, a localised effect. This excuse, for want of a better term, is now being used in other places for other events.
    We can expect much more of this.

  5. I recall this article in the Los Angeles Times back in March 2016:

    “Hikers barred as glaciers melt; In New Zealand, rapid melt caused by climate change makes hikes too dangerous.”

  6. So global warming is not global?
    Next they tell you that manmade global warming is not manmade?

    Interesting!

    They will still tax you for it though, because they can.

  7. Excellent post.

    It does seem that, since the very active sun gave way to the “quiet sun”, certain areas have experienced cooling. A study recently noted the southeast USA has experienced cooling over the past half century or so, but they didn’t call it “cooling” or even “periods of reduced temperature.” Instead they called it “A warming hole.”

    (Very Orwellian, but a bad choice of words. I have heard an amazing number of rude responses, all based around the word “hole.”)

  8. Ive hiked up that glacier in the 90s no climate change will stop me!
    PS Prof Mackintosh, go back to physics school if you think there is any such thing as human induced climate change!

  9. Al Gore’s favorite (ex)glacier, Chacaltaya, in Bolivia, disappeared in 2009 but it was not a 0.3ºC of temperature rise that did it but severely reduced cloud-cover which had the effect of:
    1) reducing snowfall.
    2) increasing sublimation of ice (a solid) to water vapour (a gas). Chac’ mostly “blew away”. It was a very short, steep, shallow glacier where the sweep-time for a snowflake falling at the top, to it melting at the bottom was only a few years. By contrast the Tasman Glacier of NZ has a long sweep-time so changes in snowfall, melting and sublimation in the high cirques may not be experienced at the snout for decades.
    These multiple factors are modulated by the amount of moraine covering the glacier. A foot of rock debris effectively insulates against summer melt and sublimation. No two glaciers are the same, hence some appear to grow while others, with different factors, recede. The Tasman has many tributary glaciers feeding into one super glacier so there is an averaging effect.
    In my estimation, the recession of the Tasman Glacier will halt during the 2020s and snowfall will increase so by 2040 my children will see it growing again. By then Prof Mackintosh, AGW, myself and Iceagenow may not be around. Humans tend to forget how short-lived and insignificant we are in the ebb and flow of nature.
