The southern limit of arctic icebergs in the Atlantic is primarily determined by the Gulf Stream and its extension, the North Atlantic Drift. The Gulf Stream does not move very much, so this limit is not changing. However, global warming could eventually stall the currents of the Gulf Stream and, counterintuitively, allow icebergs to penetrate further south into the open Atlantic. Very few icebergs occur in the northern Pacific, and those that do tend to stay close to Alaska; they don't approach their theoretical southern limit.
