Abstract. We contribute to the debate on glacial shrinkage in the Himalaya by analyzing glaciers in southern slopes of Mt. Everest that are characterized by extensive debris coverage and the highest elevation in the world. In this paper, we make a complete analysis from 1962 to 2011, considering five intermediate periods using optical satellite imagery. We found an overall surface area shrinkage of 13.0 ± 3%, an upward shift of 182 ± 9 m in snow-line altitude (SLA), a terminus retreat of 403 ± 9 m, and an increase of 17.6 ± 3% in debris coverage. The recession process of glaciers has been relentlessly continuous over the past fifty years. Furthermore, since early 1990s, we have observed an acceleration of the surface area shrinkage, which resulted in a median annual rate double that of the previous three decades (an increase from 0.27% a−1 to 0.46% a−1). Comparing the SLA over the same periods, it shifts upward with a velocity almost three times greater (from 2.2 ± 0.5 m a−1 to 6.1 ± 0.9 m a−1), which points to a worsening of the already negative mass balance of these glaciers. However, the increased recession velocity has only significantly affected glaciers with the largest sizes, which are located at higher altitudes and along the preferable south-oriented direction of the monsoons. Moreover, these glaciers present median upward shifts of the SLA that are double others; this finding leads to a hypothesis that Mt. Everest glaciers are shrinking, not only due to warming temperatures, but also as a result of weakening Asian monsoons registered over the last decades. We conclude that the shrinkage of these glaciers is less than that of others in the Himalayan range. Their position in higher elevations have surely reduced the impact of warming on these glaciers, but have not been excluded from a relentlessly continuous and slow recession process over the past fifty years.
