I think it's a bit early to hang the European winters on the Labrador current.

Well, I suppose depends on your purpose.  

If you want a complete description (model) of what is happening right now, it is indeed too early.  You will have to wait several decades, at which time it will be of historical interest only.  

On the other hand if you are trying to look ahead, and anticipate what will happen, by discerning what is likely, it is not too early at all.  I think we are just mystifying ourselves if we insist that it all about the North Atlantic Oscillation being disturbed.  Sure it is disturbed!--but what is the rest of the story?  Admittedly, by focusing the Labrador current I am simplifying, but I think this is a key piece, which is, moreover, easy to understand.  

Like most of us, I would like to have more information and more data, but I think the significant point of this article is that though the means are indirect it does establish a rough picture of what is happening that can be debated in detail but in the large leaves little doubt.  

Corals really do respond to nutrients in the water, and nutrients really can be associated with ocean currents, so that part is not open to doubt.  

I am no longer interested in debates about climate change per se.  I can look out my window and see the climate is changing, and anyone who has lived a few decades in one place can do the same.  

But I am very much interested in looking ahead to what is coming--what we can expect.  

The Fates are kind.
