Although there has been some thinning of coastal ice in Greenland, the total ice mass there is actually increasing because of a rapid increase in ice thickness at higher elevations. If we could cause all of Greenland's ice to melt into the sea, it would raise the sea level by 7 meters, as the scaremongers say, but that scenario does not appear likely given the data. One should also take note that during the last decade, Greenland has not become warmer. It has become colder. It is therefore not possible to ascribe changes in its ice mass to global warming or to greenhouse gases from fossil fuels. As a footnote, Greenland's coast was in fact green with vegetation in the tenth century when it was discovered by Nordic sailors. It was warmer then than it is now. It has not fully recovered from the Little Ice Age that occurred in the Middle Ages.
