This book gives a comprehensive overview of our present understanding of the Earth's cryosphere, its changes and their consequences for mean sea level changes. Since the middle of the 19th century there has been an increase of sea level height by 20-25 cm. Some 8-10 cm of this is due to net losses from glaciers, the remainder being due to mass losses from land ice and thermal expansion of the oceans. The mean sea level rise is slowly accelerating; at present it is some 3 mm/year. Recent space observations made by the GRACE satellite combined with ocean temperature and volume measurements...
