You said, "are you distorting the data...", which I took it to mean am I doing something to the data or images.
A couple of points:
One, it's not MY interpretation, it's NASA's interpretation.
Two, they emphasize the appearance of the ice, as gray with meltwater lakes (bright little blue spots) as showing where the melt zone is. Snow cover looks different, and it's not covering the meltwater lakes.
Three, I suspect that the images were taken on a lucky clear day at approximately the same time each year.
Four, NASA has also performed laser measurements from a plane that shows that the actual ice edge in Greenland is receding, so this result would support that result.
Five, instead of arguing with me, investigate this on your own. I suggest starting by going to the linked page and reading the article "Vanishing Ice", as is suggested in the text. It's interesting. Below are some other short articles to read:
Mapping the Greenland Ice Sheets
Six, NASA launched a satellite late last year called ICESAT that will provide measurements that will be able to quantify whether or not the Greenland and Antarctic ice sheets are growing or shrinking.
So, with regard to these icy images: "chill out", Mark.
