Do the Arithmetic on Global Warming

The image on the right shows the additions and subtractions from the Greenland ice sheet annually. The web page claims that there is a net decrease of 53 cubic kilometers of ice per year in Greenland. They are talking about 53 cubic kilometers out of 4 million cubic kilometers. The idea that anyone could measure 53 cubic kilometers of net ice melt per year (.00001, one hundred thousandths of the total) is absurd.
The further idea that this incredibly insignificant amount of ice from the net melt of Greenland could create a trend of .005 inch per year rise in the oceans is even more absurd. That would be .5 inch in a century. Half an inch increase in a century in oceans that already vary with tidal action by 45 inches twice a day every day is quite hard to picture as a global danger.
