Greenland, ice sheet and melting

Greenland ice sheet could fully melt after reaching specific tipping point, study finds
Greenland's ice sheet currently spans over 1.7 million square kilometers and is the largest freshwater reservoir in the northern hemisphere. The ice sheet has already lost over a trillion tonnes of its total mass since the 1980s,
Dark algae could accelerate melting of Greenland ice sheet
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
Scientists Pinpoint ‘Tipping Point’ for Greenland’s Melting Ice Sheet
The vast landmass is melting quickly due to climate change, and may rapidly cause the complete loss of the island's ice.
Greenland Ice Sheet melting is accelerated by ice algae that thrive without extra nutrients
The melting of the Greenland Ice Sheet is the single largest contributor of freshwater to global sea-level rise. Previous research has shown that algal blooms on the ice sheet’s western margin can enhance melt rates by 10 to 13%.
Algae may speed up Greenland ice melt
The tiny ice inhabitants darken the glacier surface and can thus accelerate its melting.
Greenland Ice Algae May Accelerate Melting More Than Expected
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.
How glacier ice algae accelerate Greenland ice sheet melting
Cutting-edge study reveals dark-pigmented microalgae's efficient nutrient uptake on Greenland ice sheet, intensifying melting and sea-level rise.
Resilient algae may speed up Greenland ice melt
New research reveals that ice algae can store nutrients which may enable them to colonize more of the ice sheet, darkening and melting it.
Resilient algae darken glacier surface and may speed up Greenland ice melt, study finds
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.
