Global warming: melting of 51 % of the glaciers in Peru in 50 years

Réchauffement climatique: fonte de 51 % des glaciers du Pérou en 50 ans

LIMA | global warming has caused the melting of 51 % of the surface area of glaciers in Peru in the last 50 years, which has resulted in the formation of new lakes, announced on Sunday the national Authority of Water (ANA).

“Peru has lost 51 % of its surface ice over the past 50 years due to the effects of climate change on these water reserves are solid,” says a report of the ANA.

The report of the ANA, which covers the period 1948-2019, reveals that new lakes formed in connection with the withdrawal of the glaciers were identified.

“The glaciers are ecosystems very sensitive to climate change. In recent decades, the effects have been more evident, resulting in a significant decrease in the mass of glaciers and the formation of new lakes, ” according to the ANA.

Peru has more than 8 000 mountain lakes. The glacier Pastoruri, long of 5 200 metres, located in the region of Ancash (north) and one of the tourist gems of the national park of the Huascarán, is the most affected with more than 50 % of its surface melted due to climate change.

“Between 1980 and 2019, it has retreated more than 650 meters, forming a new lake in contact with the glacier and continues to grow “, according to the report. The glaciers of Uruashraju and Yanamarey, also located in the region of Ancash, declined by an average of one kilometre between 1948 and 2019.

Peru counts a total of 2 679 glaciers representing approximately 2 000 square kilometres. At the national level, the ANA monitors 13 glaciers located in the centre and south of the country.

Peru has the largest chain of mountains in tropical and 71 % of tropical glaciers in the world, as well as 27 of the 32 climates in the world, according to the ANA.
