In November of 2013, a mind-bogglingly large iceberg split off of the front of Pine Island Glacier in West Antarctica - one of the world's fastest flowing glaciers.
Dubbed B31, the iceberg was "roughly the size of Singapore", according to Nasa.
At the time, the massive iceberg was mainly viewed as yet another global warming sign - after all, the melting of West Antarctica, due to warm ocean waters that are reaching glaciers like Pine Island and melting them from below, is perhaps the world's No. 1 sea-level threat.
New research, however, suggests that while global warming is probably leading to more gigantic icebergs breaking off of Antarctica (and more icebergs in general), there could be a silver lining.
