Snow. A single word, for an infinite variety of water formulations, frozen in air. The study of snow is physics, chemistry, meteorology, anthropology, geography, poetry and art. It is hope – annually renewed. And it is history, too. Earth saw its first snowfall 2.4 billion years ago. The world’s oldest skis, made by hand five thousand four hundred years old, pre-date the pyramids of ancient Egypt. To humanity, snow has variously been an ally and an adversary; an inspiration to countless artists and a place of breathtaking tragedy and survival. But it’s always been there. And now it is melting. As the seasons lose their rhythm, and whole landscapes risk vanishing, shrinking too our planet’s ability to reflect sunlight, Swedish environmentalist Sverker S?rlin urges that we take the time to look at what it is we’re losing, in all its multifaceted wonder. And to question, what comes next?
