Geography asks three questions:
Yesterday morning as we flew into Cusco, our pilot seemed to have deliberately tipped the wing so we could have a good view of Salcantay -- it was amazing to see from above, and looked just about like it does on the satellite imagery above. (Pan and zoom to see more of this fascinating part of the world.)
This glorious vista brings to mind, however, the retreat of glaciers all over the world. The water stored in this form melts and feeds both ecosystems and crops below, throughout the Andes, the Himalayas, and other highlands throughout the world -- the kind of disparity in climate-change vulnerability that has been the focus of Mary Robinson.
Many of the world's refugees from climate change will be people who can no longer farm in areas near glaciers like this one. In some cases, those changes have already begun, as I wrote last year in The Most Important Town in the Americas.
