Man of the Glaciers: Antarctic Researcher Claude Lorius (Enhanced DVD)
Product Description:
French glaciologist Claude Lorius discusses his explorations in Antarctica. His missions involved "heavy-hydrogen analysis of drilled ice core samples". Journey with Lorius as his exploits led him to the scientific proof of global warming.
His first expedition, in the mid 1950's, Lorius spent a year in the South Pole researching climate change. In 1959, Lorius and other scientists explored the continent of Antarctica. At that time there was little known about the land, so Lorius took measurements and evaluated the area. He used a method of measuring hydrogen ice to determine temperatures from years ago in order to recreate past climate fluctuations.
In 1977, Claude Lorius was able to drill, taking core samples from Antarctica's ice. He wanted to know if he could map prehistoric weather patterns. After analyzing the ice, the research team found that there was less carbon dioxide in the ice 20,000 years ago. This analysis was proof that the climate has changed over time.
During the Cold War, surprisingly, French and Soviet glaciologists collaborated to discover ice cores that were at least 150,000 years old.
