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!
