Hypothesized drawdown of the East Antarctic Ice Sheet through the “bottleneck” zone between East and West Antarctica would have significant impacts for a large proportion of the Antarctic Ice Sheet. Earth observation satellite orbits and a sparseness of radio echo sounding data have restricted investigations of basal boundary controls on ice flow in this region until now.

Marine salvage experts are floating a plan to tug icebergs from Antarctica to South Africa's drought-hit Cape Town to help solve the region's worst water shortage in a century.

A new IMAS-led study has revealed a previously undocumented process where melting glacial ice sheets change the ocean in a way that further accelerates the rate of ice melt and sea level rise.

Strong heat loss and brine release during sea ice formation in coastal polynyas act to cool and salinify waters on the Antarctic continental shelf. Polynya activity thus both limits the ocean heat flux to the Antarctic Ice Sheet and promotes formation of Dense Shelf Water (DSW), the precursor to Antarctic Bottom Water. However, despite the presence of strong polynyas, DSW is not formed on the Sabrina Coast in East Antarctica and in the Amundsen Sea in West Antarctica.

The populations of the Adelie and Chinstrap penguin species are declining as there shortage of food and their snowy habitat is shrinking

Although we all show concern or pay lip service on increasing phenomena of climate change, there is lack of discussions or community mobilisation as to how to conserve environment and curb the phen

Grounding lines are a key indicator of ice-sheet instability, because changes in their position reflect imbalance with the surround-ing ocean and affect the flow of inland ice. Although the grounding lines of several Antarctic glaciers have retreated rapidly due to ocean-driven melting, records are too scarce to assess the scale of the imbalance. Here, we combine satellite altimeter obser-vations of ice-elevation change and measurements of ice geometry to track grounding-line movement around the entire conti-nent, tripling the coverage of previous surveys.

The world's fisheries will be, on average, 20 per cent less productive in the year 2300, according to a study.

Climate change is likely to have a devastating impact on King penguins if global warming continues at its present rate, scientists warn.

The world’s sea ice shrank to a record January low last month as the annual polar melting period expanded, experts say.
