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.
