dc.descriptionOriginal abstract: We analyzed 19 annual Landsat ThematicMapper images from 1984 to 2011 to determine changes of the glaciated surface and snow line elevation in six mountain areas of the Cordillera Huaytapallana range in Peru. In contrast to other Peruvian mountains, glacier retreat in thesemountains has been poorly documented, even though this is a heavily glaciated area. These glaciers are the main source of water for the surrounding lowlands, and melting of these glaciers has triggered several outburst floods. During the 28-year study period, there was a 55% decrease in the surface covered by glaciers and the snowline moved upward in different regions by 93 to 157 m. Moreover, several new lakes formed in the recently deglaciated areas. There was an increase in precipitation during thewet season (October–April) over the 28-year study period. The significant increase inmaximum temperatures may be related to the significant glacier retreat in the study area. Therewere significant differences in thewet season temperatures during El Niño (warmer) and La Niña (colder) years. Although LaNiña yearswere generallymore humid than El Niño years, these differenceswere not statistically significant. Thus, glaciers tended to retreat at a high rate during El Niño years, but tended to be stable or increase during La Niña years, although therewere some notable deviations fromthis general pattern. Climate simulations for 2021 to 2050, based on the most optimistic assumptions of greenhouse gas concentrations, forecast a continuation of climatewarming at the same rate as documented here. Such changes in temperature might lead to a critical situation for the glaciers of the Cordillera Huaytapallana, and may significantly impact the water resources, ecology, and natural hazards of the surrounding areas.es_ES

En contraste con otras montañas peruanas, el retiro de glaciares en estas montañas ha sido pobremente documentado, a pesar de que esta es un área muy glaciar. Estos glaciares son la principal fuente de agua para las tierras bajas circundantes, y la fusión de estos glaciares ha provocado varias inundaciones.es_ES
