Although the ice cover has increased over the past few years, the Arctic's sea ice is now much thinner than it was just a few years ago, making it more vulnerable to future warming.

Both the area of water covered by sea ice and the thickness of the ice have been decreasing in recent years, and thinner ice is blown farther and faster by the wind.

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 shelvsea 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 shelvSea coast, indicating increased basal melting due to increased ocean heat fluxes in the cavities below the ice shelves.

Actual visual observations of sea ice recently made from aircraft during buoy deployment operations over the Arctic by the Naval Oceanographic Office and National Guard confirm that the ice cover is noticeably thinner and that it is more fractured than in previous years.

However, such an approach not only neglects the effect of year - to - year or longer - term variability (Overland and Wang, 2013) but also ignores the negative feedbacks that can occur when the sea ice cover becomes thin (Notz, 2009).

An arctic ice pack that consists mostly of first - and second - year rather than multi-year sea ice, implies a thinner, more mobile ice cover relative to conditions five or more years ago.

This has resulted in thinning and reduction in sea ice cover leading to a new dynamical regime in which sea ice fracturing and ridging are more frequent.

Peter Wadhams, professor of ocean physics at Cambridge University, who was branded «alarmist» after he first detected «substantial thinning» of sea ice in 1990, said: «The entire ice cover is now on the point of collapse.»
