Antarctica’s massive ice sheet has been covering an active volcano, scientists announced yesterday. When it erupts — as it’s likely to sooner or later — it could potentially accelerate meltwater flow and further contribute to rising sea levels.
In a study published in the journal Nature Geoscience, a group of researchers revealed that “earthquakes” they detected deep beneath the ice turned out to be the rumble of magma activity. While it’s long been suspected that there might be active volcanoes there, it had never been confirmed before now. The study’s lead author, Amanda Lough, explained the discovery’s implications to New Scientist:
There’s no way to know when, or if, the buried volcano will erupt again. “I can’t put a date on when the next one’s going to happen,” says Lough. But if it does go off, the molten rock will melt the base of the ice, sending liquid water flowing under nearby ice streams. These would start moving faster as a result, dumping more ice into the sea, and causing sea levels to rise a bit faster. “I don’t think it’s going to cause major ice sheet failure, but it’s going to be noticeable,” says Lough.
And other experts unaffiliated with the study tempered Lough’s predictions as being “highly speculative,” citing the need for more research about the volcano’s ability to contribute to sea level rise. Climate change remains, by far, the thing we should be most concerned about — and the volcano’s a wild card that, worst-case scenario, would pile on to an already critical situation.

Like little stars.
World's best pie apple. Essential for Tarte Tatin. Has five prominent ribs.
So pretty. So early. So ephemeral. Tastes like strawberry candy (slightly).
My personal fave. Ultra-crisp. Graham cracker flavor. Should be famous. Isn't.
High flavored with notes of blood orange and allspice. Very rare.
Jefferson's favorite. The best all-purpose American apple.
New Hampshire's native son has a grizzled appearance and a strangely addictive curry flavor. Very, very rare.
Makes the best hard cider in America. Soon to be famous.
Freak seedling found in an Oregon field in the '60s has pink flesh and a fragrant strawberry snap. Makes a killer rose cider.
Ben Franklin's favorite. Queen Victoria's favorite. Only apple native to NYC.
Really does taste like pineapple.
