Satellites see Unprecedented Greenland Ice Sheet Melt 14 years ago
There is a legend.
'In the image, the areas classified as "probable melt" (light pink) correspond to those sites where at least one satellite detected surface melting. The areas classified as "melt" (dark pink) correspond to sites where two or three satellites detected surface melting.'
While I do feel that the use of the word "unprecedented" was not warranted (and should be criticized), the rest of the article is fine.
