This article in Nature Communications caught my eye!
This is a beauty. This week, Nature Communications published an explanation as to why (at least) 58 New Zealand glaciers grew in the twenty-five years to 2008.
The aberrant behaviour by these naughty glaciers was perfectly explicable though – it was caused by “regional cooling”.
Researchers from NZ’s National Institute of Water and Atmospheric Research and Victoria University prepared, yes, a model of the Southern Alps. And yes, they found that in their model, lower air and adjacent ocean temperatures (during those 25 years) were correlated with the growing glaciers.
But where is the support for this claim ?
“While this sequence of climate variability and its effect on New Zealand glaciers is unusual on a global scale, it remains consistent with a climate system that is being modified by humans”
