Patagonian Glaciers Melting Is Increasing, According To ESA’s CryoSat Measurements


As ESA’s CryoSat satellite provides data on ice meltdown and on the shrinking ice cover of Antarctica and Greenland, it has surpassed all the expectations by disclosing exactly how mountain glaciers are also retreating due to global warming. Recent CryoSat data revealed that the Patagonian glaciers melting is increasing.

All glaciers on Earth are in retreat

In fact, over the past 15 years, the glaciers’ ice meltdown has been the main culprit for the increase in sea level. Besides, Patagonia hosts the largest glaciers in the southern hemisphere, lagging only slightly behind Antarctica.

Unfortunately, Patagonian glaciers are also experiencing one of the most rapid glaciers thawing, worldwide.

The reason behind this is the global warming which causes moderate climates. These glaciers typically drain into fjords and lakes, causing them to meltdown more rapidly and to leak ice in the shape of icebergs on their shores.

Watching and comprehending the glaciers’ behavior is very useful, not only in Patagonia but throughout the planet.

ESA’s CryoSat satellite shows that Patagonian glaciers melting is increasing

A recent article issues in the Remote Sensing of Environment outlines how the CryoSat satellite has been used to unveil intricate patterns in the rapidly fluctuating heights of Patagonian glaciers.

Luca Foresta from the University of Edinburgh stated that thanks to CryoSat the scientists have been capable of revealing that, since 2011 and until 2017, the Patagonian glaciers’ densities was widely occurring, in special in Northern Patagonia.

For instance, the Jorge Montt glacier, which is stretching to the ocean, shrank by 2.5 km and drained about 2.2 gigatons of ice per year. Also affected by glaciers melting due to global warming, the Upsala glacier, which leaks into a local lake, dropped about 2.68 gigatons each year.

In opposition, there is the Upsala Glacier which is the largest in the region has shredded only 0.67 gigatons per year.

According to ESA’s CryoSat reading, between 2011 and 2017, Patagonian glaciers lost 21 gigatons per year causing an increase in the sea level of 0.06mm and representing an increase of 24% in Patagonian glaciers melting compared to the last measurement made between 2000 and 2004.
