Researchers Unveil Antarctica's Map

A new study has produced the most detailed map of Antarctica's subglacial landscape, revealing thousands of hills and ridges.
Researchers used satellite data to show how topography influences ice flow and melting.
The mapping identifies a deep channel in the Maud Subglacial Basin, 50 meters deep and 6 kilometers wide.
Experts say the data will improve models of Antarctica's climate response and potential sea-level impact.

Scientists Warn Ice Loss

Antarctica's ice shelves lose 843 billion tonnes annually due to warm ocean water beneath them, risking several meters of sea-level rise if they collapse.
Dr. Ben Galton-Fenzi, a climate scientist, and scientists stress the urgency of understanding these changes, noting data shortages create uncertainties about the rate of transformation.
Researchers warn meltwater could disrupt major ocean currents and cause dramatic climate consequences.
