Global Warming

Last year was the hottest on record and the earth's temperatures are expected to continue to rise. Scientists report Antarctica is losing 36 cubic miles of ice annually. Some predict sea levels will rise three feet by 2100. That could put much of America's coastlines underwater, threatening major population centers.

What is global warming doing to the world? Has the earth reached the tipping point? How will climate change affect Idaho? Joan Cartan-Hansen and guests discuss the latest scientific studies about global warming, its impact and Idaho's future.
