00:00What if melting glaciers could wake up volcanoes?
00:03In the icy heart of Antarctica, over 100 volcanoes lie hidden beneath miles of ice.
00:09And as those glaciers melt, they're doing more than just raising sea levels.
00:13Scientists now say they might be lighting a volcanic fuse.
00:17Here's how. Glaciers are heavy.
00:20As they melt, that crushing weight lifts off the land.
00:23The Earth, believe it or not, has a kind of elasticity.
00:27That weight loss lets magma chambers below expand.
00:31Pressure builds.
00:32Volcanic eruptions can follow.
00:34And that's not all.
00:35Some magma chambers hold gas under high pressure, like soda in a sealed bottle.
00:40Remove the ice, and that gas can explode out, pushing magma even harder toward the surface.
00:46This can trigger a vicious loop.
00:48Melting ice causes eruptions.
00:50Eruptions melt more ice, and it keeps going.
00:53This process is slow.
00:55It takes centuries.
00:56But it's already begun.
00:58And even if we stop warming the planet today,
01:00these hidden reactions could keep reshaping Antarctica for thousands of years.
01:05We're unlocking new tools to understand these deep Earth changes.
01:08But will we listen in time?
