Climate Change in Peru


Glacier melt hasn't caused a national crisis in Peru, yet. But high in the Andes, rising temperatures and changes in water supply over the last 40 years have decimated crops, killed fish stocks and forced villages to question how they will survive for another generation.

Without international help to build reservoirs and dams and improve irrigation, the South American nation could become a case study in how climate change can destabilize a strategically important region, according to Peruvian, U.S. and other officials.

[..] Peru is home to 70 percent of the world's tropical glaciers, which are also found in Bolivia, Ecuador and Chile. Peru's 18 mountain glaciers, including the world's largest tropical ice mass, are critical to the region's water sources for drinking, irrigation and electricity.

Glaciers in the South American Andes are melting faster than many scientists predicted; some climate change experts estimate entire glaciers across the Andes will disappear in 10 years due to rising global temperatures, creating instability across the globe as they melt.
