Greenland's Ice Sheet 'Boils' Like Pasta, Scientists Find

Scientists just figured out why Greenland's ice sheet has been doing something totally unexpected: it's churning like a pot of boiling pasta beneath the surface.

For years, researchers spotted strange, vast structures called "plumes" hidden deep inside the ice. Nobody could explain how they formed until now.

A new study published in the journal Cryosphere reveals these mysterious features are caused by thermal convection, the same process that makes hot rock churn in Earth's mantle. Hot material rises, cool material falls, and the whole thing cycles in a continuous loop.

"We typically think of ice as a solid material, so the discovery that parts of the Greenland ice sheet actually undergo thermal convection, resembling a boiling pot of pasta, is as wild as it is fascinating," said Andreas Born, a professor of Earth science at the University of Bergen in Norway.

The finding means parts of the ice sheet are softer than scientists realized. That's a crucial detail because Greenland's ice is melting fast as the planet warms, and researchers are racing to understand exactly how quickly it will disappear.

The ice sheet spans more than 650,000 square miles. If all of it melts, sea levels could rise by a staggering 24 feet worldwide.

Why This Inspires

This discovery isn't just about solving a scientific puzzle. It's about giving humanity better tools to prepare for the future.

Understanding how Greenland's ice moves and melts means scientists can build more accurate models. Those models help coastal communities around the world plan for rising seas, from building better flood defenses to protecting homes and infrastructure.

"Our discovery could be key to reducing uncertainties in models of future ice sheet mass balance and sea-level rise," Born said.

The research shows that even when facing massive challenges like climate change, scientists keep finding answers. Every new piece of knowledge brings us closer to understanding our planet and protecting the people who call it home.

Knowledge is power, and this breakthrough gives us more of both.
