One of Antarctica’s biggest glaciers will soon reach a point of irreversible melting. That would cause sea levels to rise at least 1.6 feet

By Aylin Woodward From Business Insider Antarctica’s glaciers are melting at unprecedented rates. This rapid ice loss contributes to rising sea-levels. In a new study, scientists found that the Thwaites Glacier in western Antarctica will likely hit a point of irreversible melting, after which it will lose all of its ice over a period of 150 years.

Antarctica’s once sleepy ice sheets have awoken. That’s bad

Pin It

By Mark Kaufman From Mashable Antarctica — home to the greatest ice sheets on Earth — isn’t just melting significantly faster than it was decades ago. Great masses of ice that scientists once presumed were largely immune to melting are losing ample ice into the sea.  In a study published Monday in the journal Proceedings of the National […]

The Editor Speaks: Shouldn’t the sea level rise worry us?

Pin It

“The Antarctic Ice Sheet is an important indicator of climate change and driver of sea-level rise. Here we combine satellite observations of its changing volume, flow and gravitational attraction with modelling of its surface mass balance to show that it lost 2,720 ± 1,390 billion tonnes of ice between 1992 and 2017, which corresponds to […]

Scientists have found nearly 100 volcanoes in Antarctica — which probably makes it the largest volcanic region on Earth

Pin It

By Peter Dockrill, ScienceAlert From Business Insider Researchers have discovered what looks to be the largest volcanic region on Earth, revealing an invisible network of almost 100 unknown volcanoes lying hidden beneath the Antarctic ice sheet. A remote survey of what’s called the West Antarctic Rift System uncovered 138 volcanoes in total – 91 of […]

The West Antarctic ice shelf is breaking apart from the inside

Pin It

By Josh Hrala, ScienceAlert From Business Insider Last year, a massive 583-square-kilometre (225-square-mile) chunk of the Pine Island Glacier — a vast section of ice that holds the West Antarctic ice sheet together — broke free, heading out into the ocean to eventually melt and raise sea levels across the world. Now, new evidence from satellite imagery […]

Hidden Antarctic volcanoes are expediting glacial melt

Pin It

By Stephanie Pappas Live Science Contributor for LiveScience From Mashable Antarctica is a land of ice. But dive below the West Antarctic Ice Sheet, and you’ll find fire as well, in the form of subglacial volcanoes. Now, a new study finds that these subglacial volcanoes and other geothermal “hotspots” are contributing to the melting of […]

An alarming prediction about Antarctica made in 1978 is coming true

Pin It

By Dina Spector From Business Insider Two new studies published on Monday report that the melting of the ice sheet in West Antarctica is unstoppable and could raise global sea levels by as much as 4 feet in the next century, a higher estimate than the 1 to 3 feet laid out in the latest […]
