Something very strange is happening under Greenland’s ice | BBC Science Focus Magazine
- Latest study finds unusual plume-like convection deep under Greenland’s ice, linked to heat from Earth’s interior.
- Researchers used a mantle-convection model to reproduce plume-like ice formations.
- Findings imply Greenland ice may be softer and more stress-sensitive than previously thought.
- If all Greenland ice melted, global sea levels could rise about 7.4 meters (24 feet).
- Researchers note more frequent, larger melt events since 2000 intensify urgency for climate action.
- The study used a digital model to simulate convection in the ice sheet.
- Thermal convection in ice is unusual but explained by ice being softer than mantle.
- Institute-led study connects convection to long-lived, stable ice layers near northern Greenland.
- Scientists emphasize that plumes are not a sign of accelerated decay but a complex ice behavior.
- The Greenland ice sheet covers about 1.7 million square kilometers and holds vast frozen water.
