Climate change means, among other things, shrinking glaciers.
You might be surprised to learn that the scientific evidence linking human greenhouse gas emissions and the melting of glaciers is pretty scarce.
A new study by New Zealand researchers, published in Nature Climate Change, is only the second in the world to establish a link between the two.
It could be a handy tool in saving New Zealand's glaciers, which could disappear entirely by the end of the century.
Lauren Vargo from Victoria University of Wellington's Antarctic Research Centre led the project.
She speaks to Corin Dann.
