TL;DR: In this article, the authors provide a comprehensive overview of the studies of glaciers in the tropical Andes conducted in recent decades leading to the current status of the glaciers in terms of climate change.

TL;DR: In this paper, an 18-month meteorological data set recorded at 5150 m above sea level (asl) on Zongo Glacier, in the tropical Andes of Bolivia, is used to derive the annual cycle of the local energy balance and to compare it to the local mass balance.

TL;DR: In this paper, the authors studied the evolution of the Chacaltaya glacier since the Little Ice Age, with a focus on the last six decades and concluded that if the recent climatic conditions continue, a complete extinction of this glacier in the next 15 years can be expected.

TL;DR: In this article, a new ice core record from the Nevado Illimani (16°S), Bolivia, covers approximately the last 18,000 years BP, and a comparison with two published ice records, from Sajama (18°S) and Huascaran (9°S, Peru), documents a regionally coherent transition from glacial to modern climate conditions in South America north of 20°S.

TL;DR: The relationship between high altitude isotope signals from Andean ice cores and local or regional climate remains poorly understood as mentioned in this paper, but the results from two new drillings in Bolivia, from the Illimani and the Sajama ice caps, suggest that the Andean high altitude records are primarily controlled by precipitation variability over the Amazon basin.
