Ice melting in Antarctica is causing sea levels to rise at a massive rate and the frozen continent has lost about 3 trillion tonnes of ice in the last 25 years.

Antartica is a “natural reserve, devoted to peace and science”, according to the Antarctic Treaty System. This complex set of agreements collectively takes a firm stance on conservation, exemplified by the Convention on the Conservation of Marine Living Resources. Adopted in 1980, this convention was negotiated rapidly in response to expanding trawling of Antarctic krill (Euphausia superba). Krill are at the base of the region’s marine food web, so there were worries that a dearth of the small crustaceans would threaten the whole ecosystem, especially whales.

Of the common adjectives used to describe Earth’s southern polar region, ‘pristine’ is among the most inappropriate. The ocean around Antarctica bobs with pieces of microplastic pollution, and for decades, whales and other marine life have been stripped from the sea. The ozone hole gapes above. To find any of the advertised unspoiled wilderness, a visitor has to trek inshore and away from the direct influence of the rest of the world. Because there is another misapplied label: remote.

The melting of Antarctica is accelerating at an alarming rate, with about 3 trillion tons of ice disappearing since 1992, an international team of ice experts said in a new study.

A growing network of ice cores reveals the past 800,000 years of Antarctic climate and atmospheric composition. The data show tight links among greenhouse gases, aerosols and global climate on many timescales, demonstrate connections between Antarctica and distant locations, and reveal the extraordinary differences between the composition of our present atmosphere and its natural range of variability as revealed in the ice core record.

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
