Sea ice disappearing faster than predicted
New Zealand Herald | 13 Aug 2012
Sea ice in the Arctic is disappearing at a far greater rate than previously expected, according to data from a satellite launched to study the thickness of Earth's polar caps.

Loss of Arctic sea ice '70% man-made'
Guardian Unlimited | 25 Jul 2012
The radical decline in sea ice around the Arctic is at least 70% due to human-induced climate change, according to a new study, and may even be up to 95% down to humans – rather higher than scientists had previously thought.

Atlantic heat constrains Arctic sea ice extent
ScienceDaily.com | 27 Jun 2012
The Arctic sea ice cover is a sensitive indicator of climate variability and change. Researchers have for the first time quantified how Atlantic heat influences the sea ice extent in the Barents Sea, where the retreat in Arctic winter sea ice is the most pronounced.

Emperor penguins threatened by Antarctic sea ice loss
EurekAlert | 21 Jun 2012
A decline in the population of emperor penguins appears likely this century as climate change reduces Antarctic sea ice, according to a detailed projection published this week. The study concludes that the number of breeding pairs in a much-observed penguin colony may drop by about 80 percent by 2100.

CryoSat goes to sea
ScienceDaily.com | 29 May 2012
CryoSat was launched in 2010 to measure sea-ice thickness in the Arctic, but data from the Earth-observing satellite have also been exploited for other studies. High-resolution mapping of the topography of the ocean floor is now being added to the ice mission's repertoire. The main objective of the polar-orbiting CryoSat is to measure the thickness of polar sea ice and monitor changes in the ice sheets that blanket Greenland and Antarctica.

Arctic sea-ice loss didn't happen by chance
ScienceDaily.com | 03 May 2012
The ongoing rapid retreat of Arctic sea ice is often interpreted as the canary in the mine for anthropogenic climate change. In a new study, scientists have now systematically examined the validity of this claim. They find that neither natural fluctuations nor self-acceleration can explain the observed Arctic sea-ice retreat. Instead, the recent evolution of Arctic sea ice shows a strong, physically plausible correlation with the increasing greenhouse gas concentration.

NRL scientists optimize arctic sea ice data products
EurekAlert | 27 Mar 2012
(Naval Research Laboratory) Recent dramatic changes in the characteristics of the Arctic sea ice cover have sparked the demand for improved monitoring and forecasting. NRL and NASA are collecting data to aid in the validation and calibration for the development of predictive sea ice models.

Scientists Look for Reasons for Changed Whale Behavior
New York Times | 17 Mar 2012
Melting polar ice could be behind shifting migration patterns that brought a gray whale and her infant calf near Alcatraz.

Arctic sea ice decline may be driving snowy winters seen in recent years
EurekAlert | 27 Feb 2012
A new study led by Georgia Tech provides further evidence of a relationship between melting ice in the Arctic regions and widespread cold outbreaks in the Northern Hemisphere. The study's findings could be used to improve seasonal forecasting of snow and temperature anomalies across northern continents.
