5 Changes in the Cryosphere Ice Sheet Glaciers Lake & Snow Cover River Ice Frozen Ground Sea Ice Ice Shelf Frozen Ground: increasing permafrost temperatures by up to 2ºC and active layer thickness by up to 9 cm since early 198s. In the NH, southern limit of permafrost moving north since mid 197s, and decreasing thickness of seasonal frozen ground by 32 cm since 193s. Snow cover: between 1967 and 212, satellite data show decreases through the year, with largest decreases (53%) in June. Most stations report decreases in now especially in spring. Lake and river ice: contracting winter ice duration with delays in autumn freeze-up proceeding more slowly than advances in spring break-up, with evidence of recent acceleration in both across the NH. Sea Ice: between 1979 and 212, Arctic sea ice extent declined at a rate of 3.8% per decade with larger losses in summer and autumn. Over the same period, the extent of thick multiyear ice in the Arctic declined at a higher rate of 13.5% per decade. Mean sea ice thickness decreased by m between 198 and 28. Ice Shelves and ice tongues: continuing retreat and collapse of ice shelves along the Antarctic Peninsula. Progressive thinning of some other ice shelves/ice tongues in Antarctica and Greenland. Glaciers: are major contributors to sea level rise. Ice mass loss from glaciers has increased since the 196s. Loss rates from glaciers outside Greenland and Antarctica -1 were.76 mm yr SLE during the 1993 to 29 period -1 and.83 mm yr SLE over the 25 to 29 period. Ice Sheets: both Greenland and Antarctic ice sheets lost mass and contributed to sea level change over the last 2 years. Rate of total loss and discharge from a number of major outlet glaciers in Antarctica and Greenland increased over this period. Contribution of Glaciers and Ice Sheets to Sea Level Change Cumulative ice mass loss (Gt) 5 4 Glaciers Greenland Antarctica Year Cumulative ice mass loss from glacier and ice sheets (in sea level equivalent) is 1. to 1.4 mm yr -1 for and 1.2 to 2.2 mm yr -1 for SLE (mm) Figure 4.25 Version 11/7/214 5
