"For years, scientists have reported a steady decrease in summertime Arctic ice, but they had never before found a similar reduction in the amount of ice being created during the frigid and dark Arctic winter. This lack of effect on the Arctic winter was one defect in the scientific models of global warming. Global warming skeptics have pointed to the lack of ice melt as a flaw in global warming theory.

"But Josefino Comiso, a senior research scientist at NASA’s Goddard Space Flight Center in Greenbelt, found precisely the proof that they needed. The study showed the amount of ice at the end of the summer 2005 was the smallest seen in 27 years of satellite imaging, and probably in 100 years. “It has never occurred before in the past,” said Comiso in an interview. “It is alarming. ... This winter ice provides the kind of evidence that it is indeed associated with the greenhouse effect. I hate to say we told you so, but we told you so,” he added."
