    Climate change threatens a fragile ecosystem in the Andes

    The páramo is a high mountain ecosystem in South America's Andes rich with biodiversity and an important source of water for millions of people. It's at risk of becoming drier because of changing climate conditions. Our latest slideshow documents the efforts of IRI's Daniel Ruiz Carrascal and an international team of researchers who have been measuring how the environment of the páramo is changing over time.

    A lo largo de la cordillera de los Andes en Colombia, Ecuador, Perú y Venezuela, ubicado entre la cota máxima de árboles y la línea de lo que solíamos llamar nieves perpetuas, se encuentra el páramo, un ecosistema único e inquietantemente sublime que está amenazado por el cambio climático.

    El clima en el páramo de los Andes del Norte es húmedo y frío. Las temperaturas pueden alcanzar valores por debajo del punto de congelaciónen la noche, y aumentar rápidamente a valores cercanos a los 15°C durante el día. Pero esto no me preocupa. Al contrario, estar en este ecosistema me fascina. Por eso regreso a él, cada que puedo, con el objetivo de investigar los cambios ambientales que se están presentando en este ecosistema. Mi nombre es Daniel Ruiz Carrascal, y soy asistente de investigación a nivel de postgrado del Instituto Internacional de Investigaciones de Clima y Sociedad, y profesor asociado en la Escuela de Ingeniería de Antioquia, en Colombia.
