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... "The global oceans have been warming since the middle 1970s and several studies have shown that the warming can be attributed to a human-produced signal," said James Hurrell of the US National Centre for Atmospheric Research.No explanation of course for the final paragraph:
Not all is gloom, however. In a sign of how higher temperatures might help some fish stocks, a period of warmer waters in the 1920s allowed cod to spawn off Greenland and let a new stock break away from Icelandic waters. In the cooler 1960s, cod were unable to reproduce off Greenland and the stock collapsed.-- Nick
