Another great example of Anthony Watts' crazy making over at WUWT
Arctic Ice and the DMI deficit
October 26, 2012 by Anthony Watts
"There’s been some interest in these before and after graphs highlighted by the blog “sunshinehours” here.
"Arctic Sea Ice Not As Bad As They Claimed??? DMI" ect..."
You know looking at the graphs side by side their differences are startlingly minor in contrast to the bigger story they tell. And it's been pointed out the DMI clearly explained:
~ ~ ~
"However, the total estimated ice area is underestimated due to unclassified coastal regions where mixed land/sea pixels confuse the applied ice type algorithm. The shown sea ice extent values are therefore recommended be used qualitatively in relation to ice extent values from other years shown in the figure. In late 2012 sea ice climatology and anomaly data will be available here. "~ ~ ~ ~ ~ ~ ~ ~ ~ ~Earth sciences never achieves 99% accuracy nor 99% reproducibility, bet we can still learn from it. The overwrought responses in these comments seems like strategic tunnel focus meant to avoid the bigger message: Arctic summer sea ice is disappearing way too fast for comfort.
As for the influence of storms on the ice loss - you can learn more in an October 19th post over at SkepticalScience: "What Role Did the Arctic Storm Play in the Record Sea Ice Minimum?"
