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, 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: In this article, a distributed energy balance model was applied to Zongo Glacier, Bolivia (16°S, 6000-4900 m above sea level, 2.4 km2), to investigate atmospheric forcing that controls seasonal variations in the mass balance and in meltwater discharge of glaciers in the outer tropics.

TL;DR: The data point to a clear acceleration in glacier decline during this decade; ablation rates have been 3–5 times higher than during the former decades; and as evidenced by the data collected, ablation increases significantly during the warm phases of ENSO...
