DISCUSSION: Over 50,000 alpacas died during a recent cold snap in the Peruvian Andes. Clear skies over southern Peru caused by a persistent high pressure system have allowed temperatures to plummet in the nighttime hours. July is typically the coldest month of the year in Peru with an average temperature of only 20°F. However, temperatures this week have dropped as low as -5 °F. The dangerous cold has been devastating for poor, indigenous populations that rely on alpaca wool to make a living. The government of Peru has declared a state of emergency as the National Meteorological and Hydrological Service expects the cold temperatures to continue throughout the rest of the week.
