The latest findings are significant when it comes to our understanding of how glaciers will be impacted by man-made global warming.
To do this they analyzed variants of oxygen in single-celled algae, which were found preserved in marine sediments from the Peninsula's northeastern tip.
And by 1706, the discharge had reached levels unprecedented in the new 6,250-year record, according to the researchers. Furthermore, after 1912, there was another significant acceleration in the rate of glacial discharge. These terms refer to a belt of westerly wind that encircles Antarctica and moves north or south, dominating the middle to higher latitudes of the Southern Hemisphere, according to the Australian Bureau of Meteorology.
"A possible implication of our data is that ice shelves in this region have been thinning for at least around 300 years, potentially predisposing them to collapse under intensified anthropogenic warming," the authors wrote in the study. Recently, scientists have detected more frequent changes in the SAM which could be the result of increased greenhouse gas levels or depletion of the ozone layer in the Southern Hemisphere. Combined with the impacts of climate change, these frequent changes to the SAM could to lead further accelerated ice loss in the future.
