(Visit: [ Ссылка ]) Drilling down thousands of meters into the ancient ice preserved on earth's massive continental ice sheets, scientists can extract a wealth of information about our climate history—including periods both much colder and considerably warmer than today. Ice, dust, and tiny gas bubbles in Greenland and Antarctic ice provide myriad clues into the complex workings of earth's climate system. Join Jeff Severinghaus as he describes how he delves into earth's climate past to gain insight into our climate future. Series: "Perspectives on Ocean Science" [6/2014] [Science] [Show ID: 27845]
