Mystery Unveiled: The Magnitude and Vulnerability of Patagonian Ice Caps to Climate Change

The ice caps in Patagonia are thinning by a meter annually

A recent study by an international research group led by Johannes Furst from the University of Erlangen-Nuremberg has re-evaluated the volume of the Patagonian ice fields using remote sensing and satellite imagery. The study revealed that these ice caps hold 5,351 cubic kilometers of ice, with some glaciers reaching thicknesses of 1,400 meters.

Despite their vast size, the Patagonian ice caps are relatively unknown. These ice caps cover about 16,000 square kilometers in Argentina and Chile, making them the largest in the southern hemisphere after Antarctica. However, unlike Antarctica’s ice caps which are well known globally, these Patagonian ice caps remain largely unexplored.

The study highlighted that these glaciers are highly vulnerable to climate change and contain 40 times more ice than all the glaciers in the European Alps. The retreat of the glacial fronts is influenced by the depth of the lake basins they flow into, with faster retreat in deeper basins. The speed of these glaciers is also a cause for concern as it results in an annual loss of one meter of ice which impacts not only water resources but also surrounding ecosystems.

The increased risk of extreme weather events affecting this region highlights the urgent need for action to address climate change’s impact on these Patagonian ice caps and their ecosystems.
