Meltwater flowing beneath Antarctic glaciers can accelerate retreat: Reports

A new Antarctic ice sheet modelling study from scientists at UC San Diego’s Scripps Institution of Oceanography suggests that meltwater flowing out to sea from beneath Antarctic glaciers is making them lose ice faster.

Climate crisis: Antarctic continent posts record temperature reading of 18.3°C

New York/IBNS: Fresh fears of accelerating damage to the planet’s ice sheets and sea level rise have been fuelled by confirmation from the UN’s weather agency that the Antarctic likely saw a new temperature record of more than 18°C on Thursday.

Massive Antarctic iceberg spotted on NASA IceBridge Flight

Washington, Nov 10 (IBNS):  NASA’s Operation IceBridge on Wednesday, November 7, flew over an iceberg that is three times the size of Manhattan – the first time anyone has laid eyes on the giant iceberg, dubbed B-46 by the U.S. National Ice Center, that broke off from Pine Island Glacier in late October.

Ramp-up in Antarctic ice loss speeds sea level rise: NASA

Washington, June 15 (IBNS): Ice losses from Antarctica have tripled since 2012, increasing global sea levels by 0.12 inch (3 millimeters) in that timeframe alone, according to a major new international climate assessment funded by NASA and ESA (European Space Agency).

New UK-U.S. joint Antarctic programme to study future sea level rise

London, Apr 30 (IBNS): A new UK-U.S. Antarctic research programme to improve the prediction of future sea-level rise is launched this week (Monday 30 April 2018) at British Antarctic Survey (BAS), Cambridge.

New Antarctic process contributing to sea-level rise and climate change: Study reveals

Sydney, Apr 24 (IBNS): Anew Institute for Marine and Antarctic Studies (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.

First expedition to newly exposed Antarctic ecosystem

New York, Feb 15 (IBNS): A team of scientists, led by British Antarctic Survey (BAS), heads to Antarctica this week (14 February) to investigate a mysterious marine ecosystem that’s been hidden beneath an Antarctic ice shelf for up to 120,000 years.

IceBridge launches two sets of Antarctic flights

Washington, Oct 31 (IBNS): Scientists with NASA’s longest-running airborne mission to map polar ice, Operation IceBridge, completed a successful science flight on Oct. 29, inaugurating their 2017 survey of Antarctic sea and land ice. 

Antarctic marine life may grow faster in a warming world, says study

London, Sept 5 (IBNS): A team of scientists has discovered that a 1°C rise in local sea temperature has massive impacts on an Antarctic marine community.

Zooplankton resilient to long-term warming, finds study

London, Sept 5 (IBNS): A new study from scientists at British Antarctic Survey shows that zooplankton, tiny animals that drift in the sea making up the base of the food web, which live in the Southern Ocean have been resilient to warming ocean temperatures.

Antarctic ice rift close to calving, after growing 17km in 6 days, says study

London, June 2 (IBNS): The rift in the Larsen C ice shelf in Antarctica has grown by 17km in the last few days and is now only 13km from the ice front, indicating that calving of an iceberg is probably very close, Swansea University researchers revealed after studying the latest satellite data.

Antarctic study sheds light on central ice sheet

London, May 7 (IBNS): Central parts of Antarctica’s ice sheet have been stable for millions of years, from a time when conditions were considerably warmer than now, research suggests.
