New Zealand scientists have discovered that freak waves up to three meters can shatter polar ice hundreds of miles from the edge of the ice pack. National Institute of Water and Atmospheric Research researchers used buoys to monitor the waves during storms in the Southern Ocean. Big waves could contribute to climate change by breaking up the icy barrier around the poles according to the study published in the leading science journal Nature.
