Glaciers in South America found to retreat to lowest since Iceage: Study

Tropical glaciers of South America have retreated to their lowest since the last ice age ended 11,700 years, a new study published in the journal Science has found.

While scientists around the world have predicted glaciers to melt as temperatures in the tropics warm, the study's analysis of rocks near four glaciers in the Andes Mountains shows that the retreat has happened far faster and already passed an alarming cross-epoch benchmark, co-author Jeremy Shakun, an associate professor of earth and environmental sciences at the Boston College in the US has said.

The Andes is the primary mountain range in South America and also the world's longest, extending from south to north through countries, including Argentina, Chile and Bolivia.

The findings signal that more of the world's glaciers are likely retreating far faster than predicted, possibly decades ahead of a grim climatological schedule, according to the authors.

"Our data imply that many glaciers in the tropics are probably now
