Ocean warming may well turn out to be the greatest hidden challenge of our generation. Whilst some may be aware of the challenges a warming ocean presents to coral reefs, few know about the other consequences this holds for the ocean.

Recent salinity changes in the Southern Ocean are among the most prominent signals of climate change in the global ocean, yet their underlying causes have not been firmly established. Here we propose that trends in the northward transport of Antarctic sea ice are a major contributor to these changes. Using satellite observations supplemented by sea-ice reconstructions, we estimate that wind-driven northward freshwater transport by sea ice increased by 20 ± 10 per cent between 1982 and 2008.

Apart from global warming, another factor that aggravates the melting of glaciers in the Third Pole is air pollution. China and India are among the worst-ranked countries in air pollution.

Scientists who have been observing Antarctica have observed the progression of a large crack in one of the world's great ice shelves, the Larsen C.

More temperature could mean increased snowfall in Antarctica which could in turn help reduce the global sea-level rise by 51 to 79 millimetres by 2100, according to a new study.

A fourth production region for the globally important Antarctic bottom water has been attributed to dense shelf water formation in the Cape Darnley Polynya, adjoining Prydz Bay in East Antarctica. Here we show new observations from CTD-instrumented elephant seals in 2011–2013 that provide the first complete assessment of dense shelf water formation in Prydz Bay. After a complex evolution involving opposing contributions from three polynyas (positive) and two ice shelves (negative), dense shelf water (salinity 34.65–34.7) is exported through Prydz Channel.

Sea ice around Antarctica shrank in a warm period more than 100,000 years ago, an indication that man-made climate change could also trigger an abrupt retreat, a scientific report said Tuesday.

Researchers develop a new system that uses satellite observations to study the world's vegetation.

While most people accept the reality of human-caused global warming, we tend not to view it as an urgent issue or high priority.

Geologists have found evidence supporting the hypothesis that Indian subcontinent was part of Antarctica a billion years ago but were separated and re-united several times due to tectonic movement
