Greenland Temperature Trends

By Paul Homewood  

 

I showed some graphs last month, giving summer temperature trends in Greenland.  

 

For completeness, I am doing the same with annual temperatures.

 

The only two long running stations currently operational are Godthab and Angmagssalik. As before, I am using the unadjusted data from GISS:

As with the summer ones, we see that temperatures in the last decade or so are very little different from the 1930’s and 40’s. The only year which stands out was 2010.

 

Both stations are in the southern part of the country, and it is sometimes claimed that temperatures are rising faster at higher latitudes. We can get a clue that this is not true at Upernavik, which lies about 1000km further north than Nuuk.

Although there is no recent data, we can still see the unmistakeable pattern of the warm 1930’s and 40’s, which we see across a wide swathe of the Arctic, through Iceland, Norway and into Siberia, known as “The Warming in the North”.

This warm interlude is extremely well known and researched, yet climate scientists nowadays seem to want to ignore it, and pretend instead that Arctic warming in the last decade is caused by CO2.

 

The truth is much more prosaic – the Atlantic Multidecadal Oscillation:
