An iceberg the size of Delaware has broken off from Antarctica

Scientists have been expecting this event for months, and say it wasn’t caused by climate change. Sea levels won’t rise from this new iceberg because the ice was already in the ocean. But it’s still worrying because of the long-term impact it could have on the rest of the shelf’s ice.

“We don’t think this is caused by climate change,” Christopher Shuman, a scientist with the Cryospheric Sciences Laboratory at NASA Goddard, says in an interview. He explains that Larsen-C, at large, still maintains critical anchors to the sea floor bedrock. “If we had seen the Larsen-C lose connection with these grounding points … that would have been much stronger evidence the whole shelf is becoming destabilized.”
