The ocean currents would warm up all over the world

Explanation:

Arctic sea ice helps with the regulation of climate and keeps it cool. When the ice is melting the heat that is coming from the Sun it goes to the ocean instead of the space. This way, oceans are getting warmer and the water is expanding. Changes in the ocean can affect the whole planet. When oceans absorb the heat the circulation of the atmosphere is changing. The salt quantity is disappearing. As the water without salt is easier, currents are moving the warm water on the Equator back to the Arctic.
