A trillion ton iceberg just broke off of Antartica

An iceberg the size of Delaware weighing over a trillion tons just broke off of Antartica, Nasa confirmed. Scientists say the iceberg broke off of the Larsen C ice shelf, which is roughly 20,000 square miles. Luckily, the iceberg was already floating before it broke off, so it won't directly impact the sea levels, scientists said. “We’re going to be watching very carefully for signs that the rest of the shelf is becoming unstable.”
