Pigmented algae are well adapted to grow on exposed ice in the Arctic as the snow line recedes, raising concerns of a feedback loop that could lead to faster sea level rise

Researchers found that Greenland’s ice algae store phosphorus, allowing them to expand and darken ice surfaces, reducing reflectivity and accelerating melt rates. As climate change exposes more ice, these algae may worsen Arctic ice loss.

Glacier-covered landscapes in the high Arctic A new study published in Nature Communications reveals that dark-pigmented microalgae, which contribute

Glaciers are huge white ice masses that can reflect a lot of sunlight. However, especially where the glaciers are not covered in snow and the bare ice is exposed, they sometimes have dark patches. These are microscopic algae that grow on the ice and darken its surface.
