Latest Polar ice packs Stories
Less ice covers the Arctic today than at any time in recent geologic history.
Melting sea ice has been shown to be a major cause of warming in the Arctic.
Scientists have discovered that changes in the amount of ice floating in the polar oceans are causing sea levels to rise.
Close to 50 years of data show the Devon Island ice cap, one of the largest ice masses in the Canadian High Arctic, is thinning and shrinking.
The US National Snow and Ice Data Center reports that the extent of sea ice over the Arctic Ocean grew until the last day of March, which is the latest the annual melting season has begun in 31 years of satellite records.
In 2007, the Arctic lost a massive amount of thick, multiyear sea ice, contributing to that year's record-low extent of Arctic sea ice.
The original proposal to build a satellite that would measure ice-thickness change came from Prof. Duncan Wingham in 1998.
A new University of California, Davis, study by a top ecological forecaster says it is harder than experts thought to predict when sudden shifts in Earth's natural systems will occur -- a worrisome finding for scientists trying to identify the tipping points that could push climate change into an irreparable global disaster.
There is increased evidence that the Arctic could face seasonally ice-free conditions and much warmer temperatures in the future.
The northern coastline of Alaska midway between Point Barrow and Prudhoe Bay is eroding by up to one-third the length of a football field annually because of a "triple whammy" of declining sea ice, warming seawater and increased wave activity.
The Arctic Ocean which is located in the Northern Hemisphere and mostly in the Arctic north polar region, is the shallowest and smallest of the world’s five major oceanic divisions. The International Hydrographic Organization recognizes it as an ocean, although, some oceanographers consider it as the Arctic Mediterranean Sea or simply, the Arctic Sea, classifying it a Mediterranean sea or an estuary of the Atlantic Ocean. Alternatively, the Arctic Ocean can be considered as the northernmost...
