    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.

  2. IRI climate scientist Brad Lyon gives an overview of the climate conditions leading up to the 2010-11 drought in East Africa. He says there's a chance of La Niña forming later in the year, which could have devastating consequences for a region already plagued by widespread famine.

  5. In this interview, climate scientist Tufa Dinku discusses his work on combining weather station data with satellite information to generate high-resolution data sets that could be used for making forecasts and feed into climate risk management activities. With funding from Google.org, Dinku and his colleagues at the University of Reading have been working with Ethiopia's National Meteorology Agency since 2008 to produce these hybrid data sets, which now extend the climate record back 30 years.
