A good and thorough model is essential.
However, consider these three data points: 1) The beginning of the Industrial Age was ~260 years ago. That would make the beginning of the 20th century a full 150 years in to the period of pumping CO2 into the atmosphere.
2) The area in question near Greenland is down wind from most of the worst early fossil fuel pollution from the U.S. part of the Industrial Age. 3) Has anyone yet included the "soot" effect on polar regions from rampant 19th-20th century coal burning? We know there is a major "soot" effect on polar snow mass from diesels which is why even Bush 2 signed major diesel soot reduction legislation and the newer diesels are far less sooty. I have never heard anyone talk about older soot from coal, though.
