A Century of Climate Change in Nuuk Fjord, Greenland

Taurisano, A., Boggild, C.E. and Karlsen, H.G. 2004. A century of climate variability and climate gradients from coast to ice sheet in West Greenland. Geografiska Annaler 86A: 217-224.

What was done
In a preliminary step required to better understand the relationship of glacier dynamics to climate change in West Greenland, the authors "describe the temperature trends of the Nuuk fjord area during the last century."

What was learned
Taurisano et al.'s analyses of all pertinent regional data led them to conclude that "at all stations in the Nuuk fjord, both the annual mean and the average temperature of the three summer months (June, July and August) exhibit a pattern in agreement with the trends observed at other stations in south and west Greenland (Humlum 1999; Hanna and Cappelen, 2002b)." As they describe it, the temperature data "show that a warming trend occurred in the Nuuk fjord during the first 50 years of the 1900s, followed by a cooling over the second part of the century, when the average annual temperatures decreased by approximately 1.5C." Coincident with this cooling trend there was also what they describe as "a remarkable increase in the number of snowfall days (+59 days)." What is more, they report that "not only did the cooling affect the winter months, as suggested by Hannna and Cappelen (2002a), but also the summer mean," noting that "the summer cooling is rather important information for glaciological studies, due to the ablation-temperature relations." Last of all, they report there was no significant trend in annual precipitation.

What it means
In their concluding discussion, Taurisano et al. remark that the temperature data they studied "reveal a pattern which is common to most other stations in Greenland." Hence, we can be thankful that whatever the rest of the Northern Hemisphere may be doing, the part that holds the lion's share of the hemisphere's ice has been cooling for the past half-century, and at a very significant rate, making it ever more unlikely that its horde of frozen water will be released to the world's oceans to raise havoc with global sea level any time soon. In addition, because the annual number of snowfall days over much of Greenland has increased so dramatically over the same time period, it is possible that the presumably enhanced accumulation of snow on its huge ice sheet may be compensating for the melting of many of the world's mountain glaciers and keeping global sea level in check for this reason too. Last of all, Greenland's temperature trend of the past half-century has been just the opposite -- and strikingly so -- of that which is claimed for the Northern Hemisphere and the world by the IPCC and its climate-alarmist friends. Furthermore, as Greenland contributes significantly to the land area of the Arctic, it presents these folks with a double problem, as they have historically claimed that high northern latitudes should be the first to exhibit convincing evidence of CO2-induced global warming.

Clearly, someone forgot to tell Greenland what it's supposed to be doing.
