Good post [dead link -- see below] from the Kos blog on the climate change deniers' argument that "climate scientists predicted an Ice Age in the '70s so why should we believe them now?" Have actually never heard that argument but will be ready if any of my Neanderthal friends--all zero of them--try to use it on me.
Arthur C. Clarke wrote an eerie short story about unexplained waves of forest animals running through English towns. Heading south, of course, in advance of you know what. But that was written long before the waning of Arctic Sea ice.
Update: The post I linked to disappeared -- possibly a Kos-hosted blogger that removed content. The topic is covered elsewhere on the Kos site.
