The Arctic Ocean has become warmer and has lost sea ice over the past 40 years due to climate change. The ocean's temperature has risen at twice the global average, causing the sea ice to melt and leading to decreased salinity levels. The Arctic Ocean has also experienced a shrinking in size due to the loss of sea ice.
