About the Author: Jérôme Weiss completed his PhD in Material Science at the Ecole des Mines of Paris in 1992. He is CNRS senior scientist in the Laboratory of Glaciology and Geophysics of the Environment in Grenoble, where he led the Ice Mechanics group until 2009. His research interests cover the mechanics of geophysical objects, from the scale of lattice defects (dislocations, microcracks) to large geophysical scales. He is therefore particularly interested in scaling properties of mechanical-related variables. During the last decade, he particularly focused on the Arctic sea ice cover, its mechanical behavior, drift, and deformation, as well as its role on climate change. He has published about 85 scientific papers, including 7 solicited reviews and 6 general public articles.
