The correct response for why the temperature of the Arctic Ocean has changed during the last 40 years is:
Sea ice has melted, allowing more sunlight to hit the ocean.
This process contributes to the warming of the Arctic Ocean, as the loss of reflective sea ice allows darker ocean waters to absorb more solar radiation, leading to an increase in temperature.
