Antarctica Has a Grand Canyon, and It's Accelerating Ice Melt and Sea Level Rise | Ecocentric | TIME.com
Very interesting and explanatory video link here
"...The Ferringo rift as its called is bringing more warm sea water into the interior of the Antarctic ice sheet, which can hasten melt. "The areas that are most vulnerable [to ice melt] coincide with the areas of ancient rifting," Robert Bingham, the discoverer of the Ferringo rift and a glaciologist at the University of Aberdeen, told NBC News.... In other words, the Grand Canyon of the Antarctic is setting the stage for even faster ice loss than would happen otherwise.
Antarctica—you’re probably not going to be surprised to learn—has a lot of ice. So much ice, in fact, that if all of it were to melt, sea levels would rise by 200 ft. (60 m)—more than enough to swamp every coastal city in the world. Even in the most extreme global warming scenarios, though, that likely wouldn’t happen for centuries, but the ice sheet in West Antarctica is melting right now, faster than any other part of the frozen continent. It’s melting fast enough to contribute nearly 10% of global sea level rise, but researchers have never really understand why West Antarctica has become such a melting hot spot."
