Why is pacific ocean colder than Atlantic ocean?

The Atlantic Ocean is warmer than the Pacific Ocean. The reason for this is because there is a warm water ocean current that goes through the Gulf of Mexico. It is called the Gulf Stream. Later, as it goes up north towards Europe and Ireland, it turns into the Mid-Atlantic Drift. There is nothing to do with anything about it being in tropical waters. All in all, the Atlantic Ocean is warmer than the Pacific Ocean because of a warm water ocean current called the Gulf Stream that later turns into the Mid-Atlantic Drift.
