Greenland & Antarctica are losing ice SIX TIMES FASTER

In the time between, 1992 to 2017, Greenland and Antarctica lost 6.4 trillion tonnes of ice.

According to the worldwide team of climatologists behind the research, the unprecedented rate of melt has already contributed 0.7 inches (1.78 centimeters) to global sea level rise in the last three decades, putting the planet on track for the worst-case climate warming scenario laid out in the Intergovernmental Panel on Climate Change's (IPCC) latest report.

A team of 50 worldwide organisations with 96 polar scientists have conducted the most shocking survey of ice loss in Greenland.

According to a March 11 news release by the organization, which is supported by the European Space Agency and the US National Aeronautics and Space Administration (NASA), the rapid melting of polar ice caps could lead to an "extra 17 centimeters of sea level rise by 2100".

According to a new report, Greenland and Antarctica are losing ice six times faster than in the 1990s - now on track with the Intergovernmental Panel on Climate Change's worst-case climate warming scenario.

Guðfinna Aðalgeirsdóttir, Professor of Glaciology at the University of Iceland and lead author of the Intergovernmental Panel on Climate Change's sixth assessment report, commented, "The IMBIE Team's reconciled estimate of Greenland and Antarctic ice loss is timely for the IPCC".

In the year 2013, the IPCC predicted that the global sea level will increase by 60 centimetres by the year 2100.

"This has important implications for the future, for coastal flooding and erosion" said Professor Andrew Shepherd from the University of Leeds.

Greenland and Antarctica are shedding six times more ice than during the 1990s, driving sea level rise that could see annual flooding by 2100 in regions home today to some 400 million people, scientists have warned. This means that the polar ice sheets have already contributed a third of all sea-level rise.

A study published in November 2019 by an global team of scientists in the Proceedings of the National Academy of Sciences found that even if all the countries that are part of the Paris Climate Agreement hit their 2030 emissions targets, sea levels could still rise by about 3 feet by the year 2300.

The team behind the research - the Ice Sheet Mass Balance Inter-comparison Exercise (Imbie) - combined 26 separate surveys to compute changes in the mass of the Greenland and Antarctic ice sheets between 1992 and 2018.

Global warming is kicking in across the globe and Greenland and Antarctica are among the worst affected regions.

The accelerated ice loss puts the planet well on the way toward the IPCC's worst-case scenario. The northern polar ice sheet feels a similar sort of assault but is also experiencing surface melt from warmer air temperatures.

Earth's great ice layers, Greenland and Antarctica, are now losing mass. By the 2010s, it had climbed to 475 billion tonnes per year. The rising level of the seas in the oceans can endanger the habitat of people living in coastal areas.

'While computer simulation allows us to make projections from climate change scenarios, the satellite measurements provide prima facie, rather irrefutable, evidence'. Their satellite observations show that both melting and ice discharge from Greenland have increased since observations started.
