Greenland is melting, at least that is the headlines. Everyone in the global warming camp is quaking in their boots awaiting the great flood, foretold long ago by Algore the Magnificent.
Tonight we are going to look at the data for Greenland. There are only a few stations on Greenland which have any length at all. The longest is for Godthab Nuuk 64.17N 51.75W degrees. That record begins in 1866.
Now, if Greenland's temperature is warming, we should see it easily in the degree days above zero. Ice, of course can't melt if it is below zero. It can ablate, but ablation is not caused by global warming. So, if Greenland is warming we should see an increase in both the temperature and the number of days spent above zero deg C. The multiplication of temperature and days is called degree-days. Such calculations are used by electrical companies to estimate how much electricity will be needed for a given area. We can use it to see if there is an increase in degree-days over the past century in Greenland. Below is the degree-days for Godthab Nuuk, Greenland.
One can see immediately that the early 1930s were in general warmer at Godthab Nuuk than they are today. The 2003 peak didn't even match the peaks of the 1930s.
The second longest record in Greenland is Angmagssalik 65.6N, 37.63W. That record started in 1895. Here is the degree-days chart for that town.
Once again, the warming in Angmagssalik, as measured by degree-days, does not match that of the 1930s, yet we are supposed to all be worried about the present warming.
All the other records start after the 1930s and so don't show the warmth of the 1930s in Greenland. From one perspective, they are not useful for long term measurments, but on the other hand they show that the warming of the current days is not all that unusual. Here are Dansmarkhavn, Prins Christi, Egedesminde While these show a bit of warming since 1950, so do the other two longer term records.
I would also like to add a station which is not all that far from Greenland, Reykjavik, Iceland. It has a long record and clearly doesn't show the warming that everyone is fearing.
It is amazing what a small group of people can convince the world is true, so long as the other people don't actually care to look at the data.
