Wealthy swordfish do Norway & Greenland for school holidays

It's all too easy to blame fossil fuels for global warming, but they have brought prosperity unknown in previous generations of tropical swordfish. So much so, in fact, that there have been frequent sighting of holidaying swordfish recorded off the coast of Norway and Greenland. :::[SMH]

Parts of the North Atlantic are setting winter heat records, allowing species ranging from swordfish to jellyfish to thrive beyond their normal ranges in a shift linked by many scientists to global warming.

Temperatures in Arctic waters off northern Europe at the tail end of the Gulf Stream, for example, are about 6.7 Celsius, the highest for early January since records began in the 1930s, according to Norway's Institute of Marine Research.


In Lista by the North Sea, for example, water temperatures were a record 8.5C, 2-3 degrees above normal for January.

In recent years, salmon have been seen swimming north of the Bering Straits between Russia and Alaska, and jellyfish plagued Mediterranean beaches in 2006. Over-fishing and destruction of habitats is also disrupting marine life.

Many scientists link high global air and water temperatures in recent months to an El Nino weather event warming the eastern Pacific, and to global warming stoked by burning fossil fuels.

The longer-term warming trend is affecting all oceans.

"The Indian Ocean has had an overall warming trend attributed to the overall warming of the oceans," said Nerilie Abram of the Australian National University.

Abram said droughts in Indonesia and perhaps Australia might become more frequent as a result of changing ocean and monsoon conditions.

Global warming alarmists would deny swordfish their new found mobility. They would turn back progress and condem these magnificant creatures back to their humble beginnings in Australia, back to being hunted by wealthy tourists from Norway.
