Everything that is happening or will happen has happened before.
I very much doubt if this is unique. In the 'Medieval Warm Period', which came on in a matter of decades, is known to have melted glaciers on Greenland and the ice cap enough to allow the Vikings to begin prowling around the N Atlantic for 400-700 years, depending on which research is believed. And then the 'Little Ice Age' followed.
That may be happening again or maybe it's a different and shorter cycle.
