• Sommario/riassunto: Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 180.This volume addresses the rapid decline of Arctic sea ice, placing recent sea ice decline in the context of past observations, climate model simulations and projections, and simple models of the climate sensitivity of sea ice. Highlights of the work presented here includeAn appraisal of the role played by wind forcing in driving the decline;A reconstruction of Arctic sea ice conditions prior to human observations, based on proxy data from sediments;A modelin
