My most strenuous disagreement with the media's reporting is their unwillingness to admit that there are untold variables in each environmental issue, and that scientists are only beginning to uncover a portion of the complex interconnectedness of creation. They operate from a position of unconscionable arrogance when they claim that they know the cause of whatever global warming crisis might exist. Of course, when a Creator is denied, why should there be any humility?
Anyway, here is another one of those recently discovered variables which effect the global climate - not caused by, nor able to be manipulated by, mankind.
A team of NASA and university scientists has detected an ongoing reversal in Arctic Ocean circulation triggered by atmospheric circulation changes that vary on decade-long time scales. The results suggest not all the large changes seen in Arctic climate in recent years are a result of long-term trends associated with global warming.
...Reporting in Geophysical Research Letters, the authors attribute the reversal to a weakened Arctic Oscillation, a major atmospheric circulation pattern in the northern hemisphere. The weakening reduced the salinity of the upper ocean near the North Pole, decreasing its weight and changing its circulation.
...Morison said data gathered by Grace and the bottom pressure gauges since publication of the paper earlier this year highlight how short-lived the ocean circulation changes can be. The newer data indicate the bottom pressure has increased back toward its 2002 level. "The winter of 2006-2007 was another high Arctic Oscillation year and summer sea ice extent reached a new minimum," he said. "It is too early to say, but it looks as though the Arctic Ocean is ready to start swinging back to the counterclockwise circulation pattern of the 1990s again."
I wonder when this little tidbit will be widely reported in the media.
Thanks to Ace for the news. No thanks to Al Gore, who seems to have overlooked it.
