Melting of Greenland ice sheet

Bbc World Service
About this episode
Record-breaking global temperatures are accelerating Greenland ice melt at an alarming rate. Professor of glaciology Alun Hubbard has witnessed the melt first hand. He tells us how the ice sheet is being destabilised and what this could mean on a human level. Also, how safe are Japanese plans to dispose of nuclear waste from the Fukushima accident? We get ... Show More
