Concerned about reports the media has tossed around about the Arctic ice being the thinnest ever? Let’s forget for a moment that the political issue is whether MAN is responsible for ‘global warming’ or it is just a periodic change as happens with ice ages and hot periods. HERE ARE SOME SCIENTIFIC numbers that put the media bias in its place!

Melting Ice: The ice melt in the Arctic has stopped and the Arctic Ocean is beginning to re-freeze as the sun has passed the September equinox. Satellite measurements showed that the ice extent of the Arctic was the least since satellite measurements began in 1979, exceeding the previous low in 2007. The alarmists are making much of the fact, as if it is proof of human-caused global warming. The skeptics are countering by pointing out that the Antarctic ice extent is exceeding past measurements.The satellite measurements have a brief history. Other measurements of Arctic ice indicate that the current melt is not unprecedented, and the beach shelves of northern Greenland indicate that the Arctic may have been largely ice free some 8,000 years ago.But two observations can be made from the some of the comments on the Arctic event. One, many of those who declare the satellite measurements of ice melt are significant ignore satellite measurements of temperatures, which show no warming trend for over a decade and these are the only globally comprehensive measurements of temperatures. Two, some are suggesting the recent events support the hypothesis that as Arctic ice shrinks, Antarctic ice expands, and vice-versa. This suggests a yet unexplained oscillation unrelated to carbon dioxide. In the solar-cosmic ray hypothesis, Svensmark et al. suggested this oscillation may be related to cloud cover. When there are fewer clouds, the Arctic warms from more sunlight, but the Antarctic cools because its ice is more highly reflective than clouds. Please see links under Changing Sea Ice.
