Scientist Susan Crockford has spent decades writing professional papers and books but has been blogging about polar bears for non-scientists since 2012.

Her books include Polar Bear Evolution: A Model for How New Species Arise, The Polar Bear Catastrophe That Never Happened, Sir David Attenborough and the Walrus Deception, Polar Bear Facts & Myths (for kids), and (for fiction lovers) a polar bear attack thriller set in Newfoundland called EATEN.
