James Balog, a regular instructor at many Summit Workshops over the years, was the featured guest on the PBS Bill Moyers hour October 17 where the topic was Jim’s Extreme Ice Project.

Over the past five years and as he has told of in previous Summits, Balog placed 25 remote Nikon cameras in all-weather housings at the headwaters of several of the earth’s shrinking glaciers.

Those time-lapse pictures provide graphic evidence of global warming or, as some critics would suggest, a natural atmospheric phasing of weather changes.

Balog has produced both a documentary film as well as a large book of the remarkable pictures. His hour-long visit with Moyers was both compelling and revealing as Balog proved he is as remarkable a scientist as an accompllshed photographer.
