The complex behavior of melting ice sheets
Today’s Video of the Day from NASA Goddard describes the complex behavior of melting ice sheets in Greenland and Antarctica.
According to NASA, if all of the ice was lost from these two regions, the ocean would rise by nearly 215 feet. It is critical for scientists to understand what influences glacial retreat in an effort to accurately predict future sea-level rise.
When meltwater bores holes into the ice, it ultimately makes its way to the glacier base and into the ocean. This plume of warm freshwater floats to the surface of the ocean, where it melts the glacier even further and can lead to calving.
