Arctic Ice Melts Faster As It Gets Warmer

If you can get over the headline without saying “DUH”, read the rest of the article.

New satellite observations show that sea ice in the Arctic is melting faster while air temperatures in the region are rising sharply, scientists say.
Since 2002, satellite data have revealed unusually early springtime melting in areas north of Siberia and Alaska. Now the melting trend has spread throughout the Arctic, according to a national collaboration of scientists.
The latest observations through September show that melting in 2005 began a record 17 days earlier than usual.

At the same time, average air temperatures across most of the Arctic region from January to August 2005 were as much as 5.4 degrees warmer than average temperature over the last 50 years, said the team of researchers from two universities and NASA.
[...]
The scientists stopped short of directly blaming the melting trend on global warming but said they have few other explanations at this point.

Sea ice records in the Arctic are sketchy before 1978. Since satellite observations began in earnest, researchers said Arctic ice has been retreating at a rate of more than 8 percent per decade.
And, they suspect, the melting may only contribute to even higher arctic temperatures in the future. That’s because the bright white ice tends to reflect more of the sun’s radiation. With more of the dark ocean exposed, the seawater tends to absorb more heat and reduce the amount of solar energy reflected back into space.

Okay, if they only record data from 1978, how do they state that there has been a warming trend for the last 50 years?
How come no one from NASA mentioned the fact that the Sun is warmer? Maybe they did, but the reporter failed to mention it?
It may well be time for me to move my family inland.
UPDATE:
Yet another article states that the trend IS due to global warming…

NEW YORK (Reuters) – The Arctic ice shelf has melted for the fourth straight year to its smallest area in a century, driven by rising temperatures that appear linked to a buildup of greenhouse gases, U.S. scientists said on Wednesday.
Scientists at NASA and the National Snow and Ice Data Center, which have monitored the ice via satellites since 1978, say the total Arctic ice in 2005 will cover the smallest area since they started measuring.

Ah Ha! Here’s a third article, from the Heritage Foundation that states:

To see if the 20th-century surface warming is from human activity or not, we begin looking in detail at the surface record. In the 20th century, three trends are easily identified. From 1900 to 1940, the surface warms strongly. From 1940 to about the late 1970s, a slight cooling trend is seen. Then from the late 1970s to the present, warming occurs. Briefly, the surface records show early 20th-century warming, mid-20th-century cooling, and late 20th-century warming.
Most of the increase in the air’s concentration of greenhouse gases from human activities–over 80 percent–occurred after the 1940s. That means that the strong early 20th century warming must be largely, if not entirely, natural.
