NASA has just released new aerial photographs that show, close-up, an immense, 70-mile long rift in the Larsen C ice shelf in Antarctica. The breach is 300 feet wide and one-third of a mile deep. As it grows, an iceberg the size of Delaware will break off.Operation Icebridge, in its eighth year of conducting airborne survey of polar ice, flew two missions in November around the 88th parallel. The highly sophisticated aircraft is equipped with radars, lasers, digital imaging and infrared sensors.
The Larsen ice shelf, in the East Antarctic, is of interest because two previous sections have broken off and disappeared into the sea. Larsen A collapsed in 1995. In 2002, Larsen B began to break apart. Within six weeks, a 1,235 square mile chunk of ice slipped away, which scientists attributed to warmer air temperatures. Prior to that, the Larsen B ice shelf had been stable for 12,000 years.

Stable for 12,000 years and thanks to NASA data we can see that its breakup is starting to accelerate. This data won’t be available if the Trump team ends the NASA studies as they’ve indicated they want to do. That would keep all of us in the dark unless we go private and do it on our own!
