When I think of a glacier in the abstract, I build a mental landscape of a far-away mountain, standing bright at the very rim of the world, unapproachable and unsullied by the messiness of humanity, a wondrous place that makes me feel so very small. Sadly, the rapid, accelerating, and near ubiquitous melting of the world’s mountain glaciers shows just how much a fiction it is to think of glaciers as a place apart. Now, sometimes when I think of glaciers, I see them as icons of my discontent. This gallery illustrates just what we stand to lose if human-induced climate change continues unabated. Difficult as it may be to believe, many of the places featured here could be mere memories in the decades ahead.
