00:00Melting ice in Antarctica could spark volcanic eruptions, scientists warn.

00:06As global temperatures increase, melting Antarctic ice could activate dormant volcanoes hidden

00:10for millennia beneath glaciers.

00:12This erosion of ice alters Antarctica's geology.

00:16Once considered remote, it's now vulnerable to climate change, risking not just glacier

00:21melting and sea level rise, but also potential volcanic eruptions.

00:26This unprecedented activity could transform the continent's geological dynamics.

00:31Antarctic ice acts as a lid over magma.

00:34Melting ice loosens this lid through glacial unloading, seen in Iceland and Alaska, possibly

00:39leading to eruptions in Antarctica.

00:42These eruptions could accelerate ice loss, increase sea levels and disrupt global climate patterns.

00:48The risk grows with record heat, highlighting that melting Antarctic ice poses a potential

00:53geological tipping point, beyond just climate issues.

01:00Glaciers do more than store water.

01:02They weigh down the crust below, keeping magma chambers under control.

01:07When ice melts, it reduces that weight.

01:10This change in pressure allows magma to move closer to the surface.

01:13Eventually, it may lead to an eruption.

01:20Eruptions may have global effects, releasing carbon and sulfur dioxide, thus altering climate.

01:26Ash clouds disrupt air travel and visibility.

01:29Eruptions could accelerate ice loss and sea level rise, threatening coastal cities and impacting

01:35global systems beyond climate.
