Glaciers – no nonsense science

As glaciologists and glacial geologists, we respond to the article “Glaciers – science and nonsense” by Cliff Ollier in the March issue of Geoscientist1 . We believethat the standfirst of this piece, which states that the author “takes issue with some common misconceptions about how ice-sheets move, and doubts many pronouncements about the “collapse” of the planet’s ice sheets” misleads the reader by assuming that Ollier’s arguments are correct. We demonstrate in this article that those arguments are not, in fact, based on an accurate understanding of contemporary glaciology.
