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.
