Dark algae that grow on the surface of Arctic ice sheets are likely to expand their range in the future, a trend that will exacerbate melt, sea level rise and climate warming.

Dark algae could accelerate melting of Greenland ice sheet
Pigmented algae are well adapted to grow on exposed ice in the Arctic as the snowline recedes, raising concerns of a feedback loop that could lead to faster sea-level rise
