Flow of hot rocks rising from the Earth’s core beneath central Greenland is melting the ice from below and contributing to sea-level rise, study finds

Melting of ice in central Greenland is being accelerated by the heat of molten rocks rising from the core–mantle boundary, adding to sea-level rise, a study has found.

Researchers from Japan mapped out the extent and branches of the so-called ‘Greenland plume’ — the rising flow of molten rock ascending beneath the island.
