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. Our route took us along the newly constructed Caraterra Interoceanica – a highway linking the Pacific coast of Peru to ports in Brazil – and up to elevations of 4700 m. Along the way we passed the smoking Volcan Ubinas, Peru’s most active volcano, and the enormous inland sea of Lake Titicaca.

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… read more
