The Official Iceland Temperature Series – 2015
By Paul Homewood
In most parts of Iceland, last year was the coldest since 2000, in marked contrast to 2014.
The Iceland Temperature Series below is built up from the seven following sites, which have long running, high quality temperature records back to 1931 and earlier. They also present a reasonable geographic distribution. It is also important to note that the temperature data has been carefully homogenised over the years by the Iceland Met Office, to adjust for station moves, equipment changes etc. (For more detail, see here).
The warm years of the 1930’s and 40’s, and much colder ones that followed clearly correlate with the AMO cycle. Although the warmth has been more persistent in the last decade, only one year, 2014, has been warmer than those earlier years.
There is no evidence to suggest that temperature trends will increase in the next few years, and much to suggest that Iceland will suffer from a return of a very cold climate once the AMO turns cold again.
We can see the same patterns in the individual stations below:
Needless to say, the adjusted GISS versions below bear no comparison.
