Large glaciers around the world have been slowly melting and receding for centuries, “exposing” the planet’s most iconic mountains, valleys and even the Great Lakes,media CNET reported. But in recent years, this has happened more and more quickly in the Peruvian Andes.
“Here, treinta anos antes (30 years ago) was the beginning of a glacier,” said CNET journalist Eric Mack’s tour guide, pointing to the starting point of what is probably the world’s tallest sidewalk, which winds about a mile to an altitude of 16,000 feet (4,877 meters). and the bottom of the Pastoruri ice sheet.
Just a few decades ago, people came here to ski. Today, rope lines and whistle-blowing alerts warn visitors not to climb unstable glaciers. The Pastoruri Glacier is no longer a recreational playground, it has become a test of different responses to changing global warming, which is rapidly shrinking a few of the world’s tropical glaciers, most of them in Peru’s sloping Blanca Mountains.
Mack’s visit as a tourist is part of a new experiment in climate change centered on Pastoruri. But, like the glacier itself, it doesn’t seem to be doing very well. Mack also discovered a whole new series of buildings that were originally visitor centers but were empty.
The intense sunlight makes the iconic sights disappear. A project called Trail of Climate Change was launched in Peru in 2013 to highlight the sites most affected by climate change. More attention should now be paid to larger, more dangerous glaciers that are just hours away from their journeys, which could flood the communities below them. This is actually the story of Mack’s visit to Peru. Visiting the remnants of this increasingly extinct ice sheet is even more curious.
As early as 2011 and 2012, local engineers thought of covering backyard-sized glacier sits with sawmill waste to see if it could isolate the glacier ice and prevent it from melting. It’s worth noting that the idea worked. But the proof of concept did not lead to a large amount of sawmill waste covering the glacier. Pastoruri has now shrunk by more than half.
“It used to be a great place for families to ski,” says C?sar Portocarrero Rodr?guez, an engineer and glacier expert. There is no snow now, which is dangerous. The place where Peruvian families skied decades ago is now empty rock and sand drainage systems, which are left behind by the retreat of the ice caps of what is now the Huascaran National Park. In fact, the shrinking ice sheet has been divided into two small-bit rivers divided into large rocks.
In 2017, Huaraz Telegraph called Climate Change Trail a “complete failure.” At least one prominent climatologist believes Pastoruri could disappear completely within a decade.
