SNEWS® Live: Although global warming has been a topic of concern in recent years, the science behind its discovery goes back to the mid-70s. Working on the summits of the highest mountains in the world, researchers began noting the gradual loss of ice, which has capped these peaks for more than 10,000 years.
A symposium at the 2007 meeting of the American Alpine Club in Bend, Ore., brought climbers and scientists together to present their evidence on the reality of global warming as witnessed by retreating glaciers and high mountain ice.
Mark Bowen, climber and author of the book "Thin Ice: Unlocking the Secrets of Climate in the World's Highest Mountains," was among the speakers at the conference. Following the conference, Bowen met with SNEWS® Live to share some of the highlights of his talk as well as discuss our options in reversing the warming trend that threatens life on our planet.
