What is the effect of changing temperature on the Arctic Ocean as observed by scientists over the last few decades? A. there are more areas of open ocean. B. there are no changes in temperature. C. there is less saltwater. D. there is more sea ice.

Answer 1

The correct answer is A. there are more areas of open ocean.

Over the last few decades, scientists have observed that rising temperatures in the Arctic region have led to a significant reduction in sea ice extent and thickness, resulting in more areas of open ocean during the summer months. This change is a critical indicator of climate change and has various ecological and climatic implications.
