In 2015, an enormous iceberg broke off Jakobshavn Glacier in Ilulissat, Greenland in 2013. It was big enough to bury Manhattan under 980 feet of frozen water, according to news reports. The Jakobshavn glacier is one of the fastest moving ice sheets on Greenland and appears to be speeding up. Since it largely consists of ice on land, any ice that floats off will contribute to sea level rise.
