The End Of Fish and Chips?

Fast Company:

There may be nothing new under the sun, but beneath the sea is a different story. Scientists studying 28 years of data from the Atlantic Ocean have found that climate change is causing drastic changes in fish populations off the European coast--and that's bad news for cold-loving species like cod, which have fed generations of Northern Europeans.
The North Sea, a cold wind-swept patch of the Atlantic stretching from Scandinavia to the U.K., is warming four times faster than the global average.  During the last 30 years, the roughly 2°F increase in mean annual temperature (the North Sea swings between 63°F and 43°F during the summer and winter) has had a profound influence on fish growth and survival, egg maturation, and the plankton supporting food webs and commercial fisheries.
British scientists analyzed 11 surveys, covering at least a million square kilometers of the European continental shelf, and more than 100 million fish, "to get the 'big picture' of how warming is affecting fish communities," according to Stephen Simpson of the University of Bristol, whose research appears in a recent issue of Current Biology. They found that 72% of common fish species had responded to rising sea temperatures. Most species--three out of four--were growing more abundant, and hake and dab had doubled, while catches of cold-loving species, including haddock and cod, dropped by half.

I love the cod and pollock that are the staples of fish fries.  I would think the crash of Atlantic Cod populations off the Grand Banks would probably doom the traditional fish and chips, but global warming can't help.  I don't think global fish stocks can hold up to the demands of 7 billion people for cheaply mined protein.
