Greenland’s Hidden Ice Boils with Pasta-Style Convection
New computer modeling of Greenland’s ice sheet suggests deep plume-like structures arise from thermal convection—a heat-driven, slow churning process that may make some ice softer than previously thought. While this explains the plumes, researchers caution softer ice alone doesn’t automatically mean faster melt or higher sea-level rise, and further studies are needed to understand the full implications for the ice sheet’s mass balance and coastal impacts.
