Meltdown: Inside Out
In this special report from WBUR's Inside Out Documentaries, hosted by Walter Cronkite, award-winning science journalist Daniel Grossman traveled to the ends of the earth - literally - to gain firsthand accounts of the latest research on the state of the world's ice cover in this new era of climate change. Meltdown: Inside Out took listeners on a global tour from the massive ice sheets of Greenland and Antarctica, to tropical mountain glaciers, to the sea ice of the far north and south, introducing us to the leading scientists in the field. Daniel Grossman took listeners on the Greenland Ice Sheet, where a team of glaciologists uses a fascinating variety of techniques to investigate recent dramatic changes in the ice sheet's outflow. Meltdown: Inside Out next went high in the Peruvian Andes, where renowned geologist Lonnie Thompson is continuing his 30-year study of Quelccaya, the world’s largest tropical mountain glacier. Thompson explained that Quelccaya has lost 30 percent of its volume in his time there, and will probably be gone by the end of this century. In Meltdown: Inside Out, listeners heard the latest projections from scientists at the forefront of climate change study. Daniel Grossman transported listeners to the Antarctic Peninsula, where researcher Bill Fraser tracked declining penguin populations, then aboard a ship through the Arctic winter to within 800 miles of the North Pole, where he explored the anticipated effects of increased human activity.
