Scientists track 'alarming' melt in Antarctic ice shelves

Around 40% of Antarctica's ice shelves have significantly shrunk over the last 25 years, scientists said on Thursday, in findings the European Space Agency said were "alarming". The melting saw 71 of Antarctica's 162 ice shelves lose mass from 1997 to 2021 - of which 68 posted a "statistically significant" reduction, according to the study published in the journal Science …

The impact of 'global boiling': Shocking before and after photos reveal just how much the Greenland Ice Sheet melted during the 'hottest month ever recorded on Earth'

Daily Mail

Shocking before and after photos reveal just how much the Greenland Ice Sheet melted during the 'hottest month ever recorded on Earth'. According to scientists, snow falls on the Greenland Ice Sheet every winter and acts as a protective layer for the glacier ice underneath during the summer. ‹ Slide me › The new images, taken by the US's Landsat …

Greenland's melt goes into hyper-drive with unprecedented ice loss in modern times

ABC

The Greenland and Antarctic ice sheets are now losing more than three times as much ice a year as they were 30 years ago, according to a new, comprehensive international study. Key points: From 1992 to 1996, the two ice sheets — which hold 99 per cent the world's freshwater ice — shrank by more than 100 billion tonnes a …

‘Devastating’ melt of Greenland, Antarctic ice sheets found

Associated Press

The Greenland and Antarctic ice sheets are now losing more than three times as much ice a year as they were 30 years ago, according to a new comprehensive international study. “This is a devastating trajectory,” said U.S. National Snow and Ice Center Deputy Lead Scientist Twila Moon, who wasn’t part of the study. “These rates of ice loss are …

Scientists worried as Antarctic sea ice hits lowest levels ever recorded

India Today

Antarctic sea ice reached record low levels for the third time in six years, alarming polar scientists. The record was broken on February 12 this year and the sea ice level reached a new record low of 1.79m sq km on 25 February. Dr Will Hobbs, an Antarctic sea ice expert at the University of Tasmania with the Australian Antarctic …

Fissures speeding up Thwaites glacier melt revealed by deep ice-core camera

ABC

Fissures and steep terraces along the leading edge of Thwaites glacier are causing it to melt faster, whereas pooling of cool water is slowing melting at the glacier's base, new research has found. Key points: Researchers bored through a glacier hundreds of metres deep to deploy an underwater vehicle The average temperature in the ocean beneath Thwaites ice shelf is …

Fears Antarctic glacier could melt faster as it speeds up and ice shelf 'rips apart'

ABC

Antarctica's Pine Island Glacier has started moving faster again, according to new research. Key points: The glacier's movement was stable between 2009 and 2017 but sped up between 2017 and 2020 Researchers think the acceleration was caused by the glacier's ice shelf 'ripping apart', reducing friction on the glacier They say it's possible the ice shelf could break up in …

Greenhouse Emissions May Add 40 cm Sea Level Rise by 2100, Warn Expert

News 18

Sustained greenhouse gas emissions could see global sea levels rise nearly 40 centimetres this century as ice sheets in Antarctica and Greenland continue to melt, a major international study concluded Thursday. The gigantic ice caps contain enough frozen water to lift oceans 65 metres, and researchers are increasingly concerned that their melt rates are tracking the UN’s worst case scenarios …
