Scientists Report Unexpected Growth in Antarctic Ice Sheet After Two Decades of Rapid Melting
After more than twenty years of continuous ice loss, scientists have detected a surprising development in Antarctica. New satellite data shows that the Antarctic ice sheet has begun gaining mass again since 2021, marking a rare and unexpected shift in one of the planet’s most closely monitored climate indicators. Researchers say the change highlights the complexity of Earth’s climate system, even as long-term concerns about global warming remain.
For years, scientists have tracked changes in the Antarctic ice sheet using the GRACE mission and its successor, the GRACE‑FO mission. These satellites measure subtle variations in Earth’s gravity field to determine how much ice is being lost or gained. Since observations began in 2002, the data consistently showed significa...
