It would be best for humanity if the colossal ice sheets that blanket Antarctica stayed put. But, there’s growing evidence that as the planet heats up, these sprawling glaciers could begin flowing into the ocean at an accelerated pace, boosting sea levels not in feet — but yards.

To halt the melting ice, some scientists have now proposed an ambitious geoengineering plan: constructing massive undersea walls to keep Antarctica’s ice in place. 

As Earth’s temperature continues to rise due to human-caused global warming, it’s still not well understood how quickly the ice sheets might collapse, but the melting of these glaciers is already underway. Read more…
