Scientists say melting glaciers are now threatening Antarctic ocean life

Much of the scientific work on the fascinating and unique organisms occupying the seas around Antarctica has focused on concerns that rising temperatures will upend these communities. But that’s not the only aspect of climate change we should be worrying about, scientists say. New research suggests that melting glaciers, which produce runoff water that carries extra sediment down into the ocean in the form of silt or clay particles, could be causing big changes in some Antarctic communities.
