Deep Water:As Polar Ice Melts, Scientists Debate How High Our Oceans Will Rise

Rivers of defrosting ice are flowing off polar glaciers and surging into the sea. As the flow becomes a deluge, the livelihoods — and very lives — of tens of millions of people living near coastlines will soon be in jeopardy.

Daniel Grossman - veteran science journalist and regular contributor to public radio, and National Geographic blogger - joined a colorful team of climate researchers in the Australian outback studying how high and how quickly the oceans might rise.

In 'Deep Water,' Grossman brings us along on this quirky crew's adventures, while at the same time filling us in on the intriguing science of sea-level research. We witness discoveries of physical evidence, and learn about the theories of leading scientists who believe we must drastically reduce the tonnage of carbon dioxide we spew into the air.
