Eruptions of subglacial volcanoes may not be visible on the surface, but they can have consequences for the ice sheet. Heat from these eruptions can increase ice melting deep below the surface and weaken the overlying ice sheet — potentially leading to a feedback loop of reduced pressure from the surface and further volcanic eruptions.

Melting Antarctica ice reduces pressure on underground magma, triggering volcanoes. This heats ice, accelerates melting, and raises seas.

Deep beneath Antarctica’s icy surface lies an ominous secret—a vast network of active volcanoes poised for eruption. As the planet warms, the ice sheet’s protective grip is loosening, potentially igniting a cataclysmic chain reaction that could reshape the continent and accelerate global climate change.

If Antarctic ice continues to melt at its current rate, it could trigger a feedback loop which may lead to an increase in volcanic activity under the continent.

Scientists have warned that melting ice sheets in Antarctica could trigger hidden volcanic eruptions beneath the surface, creating a dangerous feedback loop that may persist for centuries. A new study based on 4,
