Just back to reply to pdq.

The BBC article I linked to referred to research at the world-renowned Proudman Oceanographic Institute in Liverpool.

You are clearly too blinkered and engaged with your own self-importance to read down that far pdq and I cannot be bothered to share bandwidth with you any more.

Go stick your head in thre trophoshere... it will clearly sustain your level of brain activity on this particular matter.

Goodbye.
