An Iceberg as Big as Manhattan is a gripping report on the new frontlines of science and the environment from the BBC's Science Editor, David Shukman. His skill is to get the big picture and to present it amid the everyday details of life and people. And these are the major stories of our day, whether Shukman is journeying up the fabled North West Passage in the Arctic, chasing after loggers in the Amazon, battling through plastic waste in the Pacific, or heading to the bottom of the sea to chart the effects of the BP oil spill in the Gulf of Mexico.
