What’s Driving Antarctica's Meltdown?

In the 11/12/2019 edition: What’s Driving Antarctica's Meltdown? What’s Driving Antarctica's Meltdown? Antarctica's ice loss is on the rise. Along with warmer water eating away at ice shelves from below, atmospheric rivers are causing trouble from above.  BY BOB BERWYN The floating ice shelves along the edges of West Antarctica that slow the flow of its vast glaciers are under assault from all directions, and they're becoming more vulnerable to collapse, scientists warn. Warmer water has started creeping in under them, eating away at the ice from below. Warmer air—and, in places, more rain—is melting the surface, creating ponds that can drain deep down and then splinter ice from within.
