Your pulse is impossibly far from the correct location. The MacKenzie freshwater pulse dumped a thick layer of fresh cold water on top of the Arctic ocean at the border of the Yukon territory. From that location the water was delayed in the Arctic long enough that it was frozen into a new very thick ice cap of fresh water rather than frozen salt water that is more vulnerable to melting.
All melting Greenland does is dump water into the vast North Atlantic where it will disperse rather than freezing into a refreshed Arctic Ice cap. Sure you might stall the Gulf Stream current for a while, but as I have pointed out ad nauseum the Gulf Stream does not transport nearly as much warmth to Europe as the long discredited theories of the 1970's once proclaimed. Western Europe is warmed by the maritime climate effect with a 1-2C increase in surface temperatures on land from the Gulf Stream. If you follow the latitude lines of Scotland around the earth to the Pacific coast of North America and look at the climate records you can easily verify that land temps in the same latitudes is within 1 C or 2 C at worst of the weather in Scotland. You can do the mirror effect and see the same is true on the pacific coast of South America at the same latitudes as far south as the continent reaches to Tierra del Fuego at 54 degrees south which roughly matches up with Newcastle England. Because of the Antarctic circumpolar current the temperature difference in Chile is greater than it is in British Columbia compared to Western Europe. The yearly average temperatures in Punta Arena the southernmost large city compares with Bremen, Germany in terms of latitude and parallels it with a -12 F or -7 C temperature effect. However the ports in both locations are ice free year around despite their distance from the equator something which is decidedly not true on the Asian Pacific coast at the same latitudes. IOW prevailing westerlies from across a large body of open water greatly warms the land on western coastlines but cold continental air flowing out to sea on eastern coastlines has the opposite effect freezing the sea far closer to the equator. You see the same effect on the east coast of North America as you do on the Asian coast. Newfoundland freezes hard while Great Britain, further north, stays relatively ice free.
