Beneath the icy expanse of western Antarctica, a hidden volcanic rift stirs silently, its activity shrouded by a 2-kilometer-thick sheet of ice. Scientists warn this geological force could trigger a chain reaction of melting and eruptions, potentially accelerating global sea-level rise. As ice continues to vanish at alarming rates, could this unseen threat hold the key to Earth’s climate future? The implications stretch far beyond Antarctica, yet much remains unaccounted for.
