They’ve studied the Antarctic since 1979 (this is true of much climate related research, Arctic, Antarctic, coral reefs…) and they are not shy to suggest that:
“Although this is a natural event, and we’re not aware of any link to human-induced climate change, this puts the ice shelf in a very vulnerable position.____ This is the furthest back that the ice front has been in recorded history._____ We’re going to be watching very carefully for signs that the rest of the shelf is becoming unstable.”
In recorded history? Give us a break. Ice breaking away is the normal.
