Arctic Sea Ice Rallies a Bit 152
radioweather writes "Like the recent stock market rebound, Arctic sea ice is making a big rally over the record low set last year. According to the Alaskan
IARC-JAXA website, satellite data which shows sea
ice extent as of 10/14/08 was 7,064,219 square kilometers, when compared
to a year ago 10/14/08 it was 5,487,656 square kilometers. The one-day gain between 10/13/08 and 10/14/08 of 3.8% is also
quite impressive. On May 5th, The National Snow and Ice Data Center suggested
the possibility of an ice-free north pole
in 2008, but so far, this year has been a banner year for sea ice recovery."

Solar output and atmospheric heat retention are two completely independent variables.
At least you admit that solar output is a variable which puts you way ahead of most of global warming people. As far as the 'atmospheric heat retention' I presume you mean the effect of the atmosperic carbon dioxide concentration which is allegedly increasing heat retention. The evidence that a change in atmospheric carbon dioxide concentration from 280 ppm at the end of the last ice age to 385 ppm today has any effect at all on 'atmospheric heat retention' is nonexistent. But even assuming the opposite, your statement above is wrong. How warm do you think a 'greenhouse' is if the sun is not shining? Not very. Atmospheric heat retention is completely dependent on solar output, not independent as you claim. No output...no heat retention. Prepare for coooooooolllllddddd.....
