I assumed that, in speaking of the Greenland ice melt, we were talking about the ice formation that was mentioned in the articles I referenced. I would suggest reading the second post to get a perspective of what I was referencing. We are talking about percentages of significance, including temperatures above freezing recorded in 2012 at the Summit station, roughly in the middle of the ice sheet itself, for the first time ever. If the whole Greenland ice sheet melted, there would be coastal flooding everywhere. If you take a look at those articles, you see specifically that the amount of ice that has melted, and the depth to which it has melted, is significant in the amount of time that it has taken place, and is a clear indication of the existence of global warming. Until the last half century, the ice sheet on Greenland was slowly growing, not rapidly shrinking.
The fact that the temperature increases are not evenly distributed around the globe does not refute global warming. The earth's atmosphere naturally reacts to changes in temperature and redistributes thermal energy. But the Antarctic ice melt is also visibly occurring, ice that has existed and covered land for thousands of years is gone, the peripheral ice along the Antarctic coast is softening and melting, and even in the Southern hemisphere, the disappearance of ice is a clear scientific measurement of global warming. It exists.
