Gulf Stream completes the shift

 You will never see something more impactful than this.  Same order as the total reversal of the Pacific Belt feed.  

I found you can overlay ocean current with temperature.  This is the map of heat energy transfer.  High temp and high current indicates energy transfer density.  It's like comparing your extension cord with one of those high voltage wires.  

As we see, all heat energy has transferred to a more southern path.  The existing temperature gradient keeps the turbulence north of this main flow going forever.  We will be able to watch the UK slowly freeze to death like a frog in ice water.  They will never know about it.

I think this will take years to be noticeable.  The oceans turn slowly but grind exceedingly fine.  The Pacific Belt turned over in 2016.
