N. Atlantic Ocean Temps Rise

Highest On Record From Newfoundland To Greenland

(AP)  Ocean temperatures in the North Atlantic hit an all-time high last year, raising concerns about the effects of global warming on one of the most sensitive and productive ecosystems in the world.

Sea ice off the coast of Newfoundland and Labrador was below normal for the tenth consecutive year and the water temperature outside St. John's Harbor was the highest on record in 2004, according to a report released Wednesday by the federal Fisheries Department.

The ocean surface off St. John's averaged one degree Celsius above normal, the highest in the 59 years the department has been compiling records.

And bottom temperatures were also one degree higher than normal, according the report.

"A one-degree temperature anomaly on the Grand Banks is pretty significant in the bottom areas, where temperatures only range a couple of degrees throughout the year," said Eugene Colbourne, an oceanographer with the Fisheries Department.

Water temperatures were above normal right across the North Atlantic last year, from Newfoundland to Greenland, Iceland and Norway.

The Newfoundland data is another wake-up call on climate change, say environmentalists.

Anchorage, Alaska, has seen annual snowfall shrink in the past decade, high river temperatures are killing off millions of spawning salmon in British Columbia and northern climates around the world have noticed warming.
