Antarctica’s Recent Status Revealed: Ice Loss Results

antarctica new status

As Antarctica continues to experience tragic ice loss, new research emerges.

The Monash University climate scientists performed a series of measurements and revealed Antarctica ice loss’s worrying status. According to their results, the ice loss persisted for many centuries after it began and is expected to continue.

The recent research highlights a cosmogenic surface-exposure chronology from Mawson Glacier that encountered a massive ice sheet retreat.

Here is what you need to know.

Antarctica’s Future in the Spotlight

According to recent research, the ice loss in Antarctica will continue for a long time, even if we learn how to control climate change. 

The data used records at least 220 meters of rough ice thinning between 7,500 and 4,500 years ago, succeeded by more regular thinning until the last millennium. Both outlet glaciers show that rough deglaciation happened across a wide area in the Mid-Holocene. 

The team’s work

The team compared the research data to regional sea-level and ocean-temperature changes. The results indicate that ocean warming most likely triggered ice drawdown and grounding-line retreat. Such a thing accelerated after a while after a marine ice sheet instability event.

The new research also unveils how the Antarctic Ice Sheet encountered the same rapid ice loss in the past. Professor Andrew Mackintosh released a statement discussing the ice loss events in the past. He detailed:

“[that] implies that ice loss unfolding in Antarctica today is likely to continue unabated for a long period.”

So far, Antarctica suffered a loss of almost 4 billion metric tons of ice layers since the mid-1990s. Researchers discovered how the ocean water is melting the ice layers from the bottom up, influencing them to lose mass quicker than they can refreeze.

Such results are the worst-case scenario for the hundreds of glaciers spread out along the Antarctic coastline. More research and observation is needed.
