Climate change is like the many-headed Hydra. We think we know it, but we don't. The Earth is re-arranging in all the places humans don't look: at sea, at the poles, deep in the melting permafrost, and in the farthest forests and mountain tops. Host Alex Smith interviews emerging threats analyst and author Robert Marston Fanney on new frontiers of climate change, and Dr. Alex Rogers of Oxford: State of the Oceans. Produced by Radio Ecoshock.
