Cold seawater is critical for the formation of sea ice, which helps to cool the planet by reflecting sunlight back to space,” said Marchitto. ”Sea ice also allows Arctic air temperatures to be very cold by forming an insulating blanket over the ocean. Warmer waters could lead to major sea ice loss and drastic changes for the Arctic.

Warming North Atlantic water tied to heating Arctic.
