Read here. IPCC climate scientists have been wrong so many times on so many issues it's a wonder anyone would be foolish enough to refer to its work as the "gold-standard." Yet again, new research throws cold water on the bogus claim that Greenland is experiencing "unprecedented" warming and its ice sheet is nearing a "tipping point." (click on image to enlarge)
In spite of all the fuss climate alarmists make about Greenland being on the verge of crossing a tipping point and beginning to experience dramatic ice loss, the results of Box et al. demonstrate there is nothing unusual, unnatural or unprecedented about the nature of its 1994-2007 warming episode. In fact, it is much less impressive than the 1919-1932 warming; and it becomes even more "less impressive" when it is realized that the atmosphere's CO2 concentration only rose by about 5 ppm during the earlier period of stronger warming but by fully 25 ppm (five times more) during the later period of weaker warming.
