Answer 1

Over the past 40 years, the Arctic Ocean has experienced significant changes, particularly in terms of temperature and sea ice conditions. The correct statement is that it **has become warmer** and **has gained less sea ice**. Average temperatures in the Arctic have risen substantially, leading to a reduction in the extent and thickness of sea ice. This process has been observed through various scientific studies and satellite measurements, indicating notable trends in warming and changing environmental conditions in the Arctic region.
