A new study published in Science finds that a critical glacier in the Peruvian Andes has shrunk to its smallest extent nearly since the end of the last Ice Age. Ohio State University glaciologist Lonnie G. Thompson is studying plants that have been recently exposed near Quelccaya Ice Cap, the world's largest tropical ice sheet, located 18,000 feet above sea level (straddling the border of Cuzco and Puno regions). Chemical analysis of plants exposed by melting several years ago showed them to be about 4,700 years old, proving that the ice cap had reached its smallest extent in nearly five millennia. In the new findings, a thousand feet of additional melting has exposed plants that lab analysis shows to be about 6,300 years old. Thompson said this indicates that ice that had accumulated over approximately 1,600 years melted back in no more than 25 years.

Radio Espinar, the local transmitter in Espinar province of Peru's Cuzco region, issued a public protest charging that it was arbitrarily ordered closed by the Transport and Communications Ministry (MTC) March 18, charaterizing the move as "repression." The MTC said the decision not to renew the license was taken because the station had failed to pay an application fee and its equipment was found inadequate. But Matilde Taco Llave, daughter and legal representative of station owner Marcelino Taco Quispe, called the closure a disproportionate move, and said it was really motivated by the station's aggressive coverage of last year's local protests against the mineral operations of multinational Xstrata. "This is a consequence of having given information about what happened in the social conflict," she said. "We are sure that this is the cause."
