Here are the facts: There was a slight warming trend from 1985 to around 2005, although there’s nothing unusual about that. Since 2005, there has been a slight cooling trend but, again, that’s not unusual.
These warming and cooling trends are caused by solar cycles, ocean currents and volcanic activity. These large and complex forces can create induction zones where warm saltier water moves under colder less saline water to change surface temperatures, which in turn affect temperatures at lower latitudes as cold Arctic water moves further south.
