DMI Show Greenland Was Warmer in 1930’s
By Paul Homewood
A few weeks ago, I ran a post on temperature trends at Nuuk and Tasiilaq (Angmagssalik) in Greenland, which I gleaned from the GISS database. The conclusion was clear, that temperatures in recent years were no higher than the 1930’s and 40’s.
I have now managed to obtain the source data from DMI, who run the whole shebang. Their figures not only support my own study, but also extend it to the three other long running sites in Greenland, Upernavik, Narsarsuaq and Ilulissat.
DMI also provide this very handy graphic:

Let’s home in on the individual graphs. (The top two, Pituffik and Danmarkshaven only start in 1948 and 1949 respectively, so don’t show the 1930 & 40’s peak).
Annual Mean Temperatures
Apart from the anomalously high temperatures in 2010, it is self evident that since 2000 temperatures across the board have been at a similar level to those in the 1930’s and 40’s. Not only that, since 2010 temperatures have been dropping away from those seen around a decade or so ago.
If we take Nuuk as an example, we find that 2014 only ranks as the 40th warmest year since records started in 1873, tying with 1895 and five other years. Last year was not an untypical year at Nuuk – 2011 was a lot colder, and this year is shaping up a lot colder.
Below are the years which have been warmer than 2014, or as warm, in Nuuk .
| 1878 |
| 1895 |
| 1916 |
| 1917 |
| 1920’s – 7 yrs |
| 1930’s – 7 yrs |
| 1940’s – 4 yrs |
| 1950’s – 5 yrs |
| 1960’s – 6 yrs |
The Greenland meltdown is one of the biggest climate scams around, fed by junk science papers such as this one which “especially focuses on the last 20 years”, and can therefore claim to detect rapid warming.
The cyclical nature of the temperature history is very clearly connected to the AMO, and has nothing at all to do with CO2, but dishonest climate scientists are not paid to give that message.

NOT A LOT OF PEOPLE KNOW THAT 
Reblogged this on Canadian Climate Guy and commented:
The facts are in the data. Any Greenland melt that has occurred over the past decades has nothing to do with increased CO2 in the atmosphere and had everything to do with the AMO.
Also, temps are not up or even above the average running mean when compared to previous decades such as the 30s and 40s.
A good find, Paul.
Gees, there that “inconvenient” 1940’s peak yet again.
Tom Wigley will be unhappy 😉
I think they were using buckets in 1940 to measure the temperature.
Thanks, Paul. It is good to look at data from a good source.
And as always, there seems to be no reason for alarm, or a reason to believe that a small rise in atmospheric CO2 has a controlling influence on the climate of this watery planet.
The water in the oceans, on land and the atmosphere does seem to have a controlling influence.
Does seem to be a slight upward trend but hey, Vikings ranched and grew corn on Greenland and as far as I can tell, we’re nowhere near those conditions. So why all the fuss? Try asking an anthropogenic CO2 zealot!
It is interesting that while Greenland is taken as an example of global warming, when you point out that its local climate has been very variable and occasionally warm in historic and prehistoric times, then it suddenly stops being an example of global warming.
Local warming is an example of global warming if there is global warming at that time, but it has no value if there is no global warming or no global warming was presupposed. This is slightly illogical.
I call this confirmation bias.
Greenland is the posterchild of AGW alarmism and as such, it will last until Atlantic oscillations make it cold again. Then it will be downgraded as a place with ‘weather’, and some other place will be the posterchild of global warming.
We live in interesting times.
I was just wondering about the AMO
Was it known to exist at that time in the 1930’s ?
The DMI maps from the period are not accurate and should be used with caution. Though i tend to think that there was less ice in the 1930’s than today,
The Hudson Bay Company started using the North West passage in 1930 and by 1937 , the last time they sent two ships through, it was company policy not to use it. Have to add that today the alarmists say that a cargo ship used it few years back as global warming had made this possible.
The Russians started using the Northern Sea Route in mid 1930s.
In the 1950s the North Russian sea routes were open for 8 months of the year.
In 1967 the Russians were going to offer up this route to world shipping but a political crisis stopped this,, the offer was made formal in 1987.
The first record I can find of the North West passage being Navigated fully was in 1838 by the Hudson Bay Company.
North-West Passage
THREE SHIPS GET THROUGH
For the first time in its history
three ships of the Hudson’s Bay
Company have made the hazardous
North-West Passage in one season.
They are the Fort James, a stout
little schooner of 130 tons with a crew
of fewer than 20 souls, the even
smaller Macpherson, which is perman-
ently stationed in the Arctic seas, and
the Baychimo, a vessel of 1,500 tons.
have to add for some reason i went off tangent about the Arctic!
Just finished reading Willi Dansgaard’s ‘Frozen Annals’, a truly riveting and insightful read on Greenland’s ice sheet research. Be warned tho’ – once you start (124pp) you’ll not be able to stop… 😉

Thank you David, it was a good read. This UHI tidbit stood out “The reactor was disassembled and removed in 1964, and the energy supply was taken over by diesel generators. The enormous energy con- sumption in the camp raised its annual mean temperature by a couple of degrees above the normal -24 ̊C, which speeded up the deforma- tion of the firn walls and ceilings that slowly caved in. Therefore, buildings and galleries fre- quently had to be cut free by power chain saws.” Re camp century approx page 46-47

Looks to me as though the temperatures at all sites show some warming, about 2 degK / century at a low significance level.
