Ice flow off Antarctica

This map of Antarctica shows the flow of ice off the continent.
the blue to pink flows at 0-10 m per year where the red to orange flows at 10-200 m per year
the yellow to white flows at 200 to 1000 m a year.
The flow rate seems to be speeding up and the scientists here are trying to find out whether it is due to global warming or just a natural fluctuation.
The ice is over 2 miles thick in places and for each meter that it progresses to the sea the ice at the coast breaks of into the sea and melts.
How will this affect the planet ?
