Question

what is the effect of changing temperature on the arctic ocean as observed by scientists over the last few decades? (1 point)
there are more areas of open ocean.
there are no changes in temperature.
there is less saltwater.
there is more sea ice.

Explanation:

As temperatures rise in the Arctic due to climate - change, sea ice melts, leading to more areas of open ocean. There have been significant temperature changes, and the amount of saltwater is not directly affected by temperature change in this context. Melting of sea ice means there is less sea ice, not more.

Answer:

There are more areas of open ocean.
