Why global warming puts bib on the menu

In our hypersensitive lifestyles, we tend to ignore those events that transpire at a slower rate. The gradual yet rapid increase in the earth’s temperature is something that presents a dire need for change, yet the gradual manifestation of its effects (as opposed the sudden shock and awe) gives rise to many “nay sayers” and as a result lets big business continue destructive practices. The “relocation” of various fish species to higher latitudes due to changing water temperatures is just one sign of many that the threat of global warming is real and this relatively slow, irreversible process will arrive with devastating consequences.

Nearly two-thirds of fish species in the North Sea have moved further north in search of colder waters because global warming is driving sea temperatures higher.

Scientists have compiled the first unequivocal evidence linking a major northward shift of North Sea fish species with rising ocean temperatures.

The researchers believe the movement is more dramatic than the simple migration of individual fish and represents a fundamental change in the distribution of marine species.

A study that covers 25 years of data has found the range of nearly two-thirds of North Sea species – including commercially important fish such as cod and haddock – have shifted either further north or to colder depths.

As cold-water fish have gone north, exotic warmer-water species such as the bib, scaldfish and lesser weever have extended their range by moving into the North Sea from the south, said Alison Perry, a marine biologist at the University of East Anglia in Norwich.

If trends continue, then Atlantic cod will no longer be able to live in the warm waters of the North Sea by 2080 and its habitat will be totally occupied by the southerly bib, Dr Perry said.

“This is not just a case of individual fish choosing to move into…
