Scientists say it could take years to find any link between massive iceberg and climate change

Scientists say it could take years to find any link between massive iceberg and climate change

Ice oozes across the surface of Antarctica and breaks off into the southern oceans constantly — but not normally in chunks the size of Delaware.

So after a massive iceberg separated from the Antarctic peninsula this week, the burning question among glacial scientists is: Was it influenced by warming seas or air, or was its separation just an abnormally dramatic stage in the natural evolution of Earth’s southern ice cap?

Though the divorce was captured by multiple satellites, researchers have little data on what might have caused it or the long list of potential factors behind it, including not just temperatures but the speed and directions of winds, currents and glacial...
