Since IPCC (2001) the cryosphere has undergone significant changes, such as the substantial retreat of arctic
sea ice, especially in summer; the continued shrinking of mountain glaciers; the decrease in the extent of snow cover and seasonally frozen ground, particularly in spring; the earlier breakup of river and lake ice; and widespread thinning of antarctic ice shelves along the Amundsen Sea coast, indicating increased basal melting due to increased ocean heat fluxes in the cavities below the ice shelv

The slight decrease in the SH is now greater then the 17 yr period, which in essence removes the global context.In addition the
increase in
sea ice in the
antarctic around 1 % per decade since 1970 is problematic at least,
