When the temperature rises on Baffin Island, in the Canadian high Arctic, ancient Polytrichum mosses are exposed from beneath melting glacier ice. Within a few years of exposure the mosses are quickly eroded away by snow and wind, but trapped beneath the ice, they can remain, frozen, for thousands of years.
