Jens Esmark, Ice Ages and Climate Change

Jens Esmark is the great pioneer in the exploration of Norway's mountains, and this is the definitive story of his life, his expeditions, mountain ascents and glacier crossings. Not the least the book traces the paths to his epochal discovery of ice ages, the most dramatic climate changes on Earth. As Esmark's supporters or opponents we meet a rich gallery of Norwegian and foreign students and colleagues. The book is compulsory reading for all mountain hikers and nature enthusiasts, and everyone with an interest in Norwegian and European cultural history.

Complete English version is available.

Geir Hestmark's biography of Jens Esmark (1763-1839) is an exemplary study that raises the history of geological science to a new level. Witty, important and well-written about how the ice formed the Norwegian mountains, while the discovery is placed in the context Norwegian and European history.
