= Case study Glaciers retreat in the Andes = Climate change has had many impacts on the outlines of our glaciers today like in the Andes or in the Himalaya where ice land has been retreating over the last few decades. Thompson L.G. Mosley Thompson E. Brecher H. Davis M. León B. Don L. Lin P. N. Mash iotta T. and Mountain K. (2006) Abrupt tropical climate change Past and present National Academy of Sciences Proceedings vol. 103 p. 10536– 10543 doi 10.1073/pnas.0603900103. The Quelccaya Ice Cap (QIC) in the Andes Perù faces major changes in its amount of ice. Studies claim that minor changes in climate change are importantly linked to the changes in the ice cap s mass balance. Stroup J. S. Kelly M. A. Lowell T. V. Applegate P. J. Howley J. A.

This retreat is due to an important rise of the Freezing Level Hight (FLH) which has approximately increased of 160 m the past six decades Yarleque C. Vuille M. Hardy D. R. Timm O. E. De la Cruz J.
