The sheet is the second largest body of ice in the world with the news a worrying updated in the battle against global warming.
Cracks in the world's second largest body of ice are growing "quicker than expected" in another scary development in Earth's battle with global warming . The Greenland Ice Sheet is cracking open more rapidly as it responds to climate change .
"This is because glaciers are accelerating in response to warmer ocean temperatures, and because meltwater filling crevasses can force fractures deeper into the ice. Crevasses are wedge-shaped fractures or cracks that open in glaciers where ice begins to flow faster. The researchers say that crevasses are also getting bigger and deeper where ice is flowing more quickly due to climate change, and that this could further speed up the mechanisms behind the loss of ice from Greenland.
“As crevasses grow, they feed the mechanisms that make the ice sheet’s glaciers move faster, driving water and heat to the interior of the ice sheet and accelerating the calving of icebergs into the ocean," study co-author Professor Ian Howat warned.

Greenland Ice Sheet Cracking at an Alarming RateA new study using 3D maps reveals that crevasses in the Greenland ice sheet are widening and deepening faster than previously thought, raising concerns about accelerated sea-level rise. The research, published in Nature Geoscience, shows significant changes in crevasse size and depth at the edges of the ice sheet between 2016 and 2021. Scientists warn that continued melting of the Greenland ice sheet could contribute to a global sea level rise of up to seven meters.

Trump to Meet with Greenland's PM Amidst Continued Ownership DisputeDonald Trump's persistent interest in purchasing Greenland, despite Denmark's firm rejection, has sparked an international debate. Trump views Greenland as a vital strategic asset due to its natural resources and location in the Arctic. While Denmark insists Greenland is not for sale, Greenland's Prime Minister has agreed to meet with Trump to discuss the matter. The meeting could potentially lead to further negotiations or, as some experts warn, a brief and unprecedented conflict.
