    Foreigners in a Strange Land

    After a very cold morning in Crucero, the sun burned off the clouds to reveal the black peaks of the Cordillera Carabaya to the east. There´s not so much snow left on the hills these days, just a few glacier patches clinging to the south faces of the highest summits.

    Into Thin(ner) Air – On Route to the Cordillera Carabaya

    This morning we left Arequipa and the comforts of the tourist trail, driving east across the puna towards the Andes proper.

    What a difference a day makes! We’ve said goodbye to the sprawling metropolis of Lima and now are happily settled in Arequipa – the White City.

    Deciphering Past Climate Change in the High Andes

    High above the tropical lowlands, the Andes form a formidable topographic barrier separating the coastal deserts in the west from the Amazon rainforest to the east. The Peruvian Andes are the highest peaks in all the tropics and, despite their proximity to the equator, are mantled with snow and ice. However, the glaciers clinging to…

    To the tip of the Andes

    In the semi-arid Andes, glaciers store water and control the runoff of mountain rivers. They feed water to big cities such as Lima and Arequipa and irrigate the surrounding lowlands. But as the planet warms, mountain glaciers in the tropics are receding steadily. Despite their paramount importance, we don’t know the scale and the rate…
