Tourists walk on the rocky base of ice and snow on top of Mount Pastoruri, 5,200 meters above sea level, in Huascaran National Park in Ancash, Peru, on September 16, 2015
Global warming caused the melting of 51% of the surface of Peru’s glaciers in the last 50 years, which caused the formation of new lagoons, reported the National Water Authority (ANA).
« Peru lost 51% of its glacial area in the last 50 years due to the effects of climate change on these solid water reserves, » indicates an ANA report.
The ANA Glacier and Lagoon Assessment Area (1948-2019) reveals in the report that new lagoons have been identified related to the retreat of glaciers.
« Glaciers are ecosystems highly sensitive to climate change. In recent decades, the effects have been more evident, generating a noticeable decrease in glacier mass and the formation of new lagoons, » says the ANA.
Peru has more than 8,000 lagoons in its 18 snow-covered mountain ranges in the country.
The snowy Pastoruri, 5,200 meters high and located in the Ancash region (north), one of the jewels of tourism in the Huascarán National Park, is the most affected with more than 50% of its surface melted by climate change.
« Between 1980 and 2019, it has receded more than 650 meters, forming a new lagoon that has glacial contact and continues to grow, » the report added.
The Uruashraju and Yanamarey glaciers, also located in Ancash, receded an average of one kilometer between 1948 and 2019.
Peru has a total of 2,679 glaciers that cover about 2,000 square kilometers.
At the national level, ANA tracks 13 glaciers located in the center and south of the country.
Peru has the largest tropical mountain chain, 71% of the world’s tropical glaciers and 27 of the world’s 32 climates, according to ANA.
