“Green snow” is spreading on the Antarctic peninsula as global temperatures rise, according to a study published today. A team of researchers from the University of Cambridge and the British Antarctic Survey have created the first ever large-scale map of microscopic algae as they bloom across the surface of snow along the coastline, playing an important role in the continent’s ecosystem and its carbon cycling. The map provides a baseline to analyse how rapidly Antarctica is turning green from the impacts of climate change. Although each of the single-cell organisms are microscopic in size, when algae densely populate the snow, it turns a vivid green across an area so large that it can be seen from space.
