If these two major ice streams continue retreating into the deep inner basins, they would raise the global sea level by ~1.5 m. In order

This far north and under a strong sea ice cover, only few internal waves are generated. Due to global warming, however, the [...] continues to drive sea ice decline, internal wave generation and mixing could increase such that enough heat from the Atlantic Water is fluxed toward the surface that even more sea ice melts.
