Highlights

Pose potential hazards and threaten the human populations and infrastructure located downvalley in the Andes (e.g., Worni et al., 2012; Cook et al, 2016; Wilson et al, 2018)
The overall glacier mass loss pattern described above appears to be related to the recent decreasing trend in precipitation observed in the subtropical region, which has clearly intensified since 2010 (e.g., Rabatel et al, 2011; Garreaud et al, 2017)
2000s to compile glacier changes of 130 SPI glaciers concluding that nearly 4% (542 km2 ) of the original area was lost with some indications of acceleration in the ice mass loss rates in recent years

Summary

Introduction

Pose potential hazards and threaten the human populations and infrastructure located downvalley in the Andes (e.g., Worni et al., 2012; Cook et al, 2016; Wilson et al, 2018). In the Central Andes the combination of the overall high elevation of the mountains with increasing precipitation levels from the Pacific produces one of the largest concentrations of glaciers in South America (Rivera et al, 2016; Barcaza et al, 2017; Zalazar et al, 2017).
