My Swedish is poor. But the graph is clear. Spitsbergen temperatures are in synch with the AMO. Some translated text below graph. (Thanks)
Contributing to making this part of the report a worrying reading is that the natural climate variations are not included in the used climate models. This is depressing, as it is well known that the air temperature around Svalbard is clearly influenced by the AMO (Atlantic Multidecadal Oscillation), which is a natural and periodic variation. This impact is actually mentioned in the report, and this realization ought to have been exploited.
Both the AMO and the air temperature in Longyearbyen have largely covaried since 1898 (see figure). The natural climate variations are thus far from unimportant, and explain better than all CO2-controlled climate models what actually takes place here in Longyearbyen.
AMO is known from measurements since 1856, and geological surveys show that AMO has been in unbroken function for at least the past 8000 years. So it is not likely that AMO will stop in the near future. AMO is currently passing a peak, and will in all likelihood decline over the next 30-35 years. We can all imagine how it will affect the Svalbard temperature. So the natural phenomenon of AMO ought to be included in the report’s assessment of the future climate in Longyearbyen with great emphasis, but does not.
The graphs start from 1950 to show a full 66 year cycle of the PDO and AMO.
I’m graphing anomalies from the mean for all. Sea Ice is in millions of sq km.
PDO versus Arctic Extent – note that the satellite record for sea ice starts at peak of PDO
AMO versus Antarctic Extent
July in the USA max temp graph looks like the 1930s (but not quite as warm).
Kinda looks like the AMO
The AMO for each month as of Dec 2015. Some months the AMO is still high. Some it is low.
This graph compares Anomaly Percent (ie if the anomaly is 1,000,000 sq km and the mean is 10,000,000 the value would be 10%)
Update: Experimental Graph Removed until I can fix my code.
Update 2: Experimental Graph 2:
Antarctic Ice Extent Anomaly vs Arctic Ice Extent Anomaly vs AMO vs PDO from 2010
(Arctic is anomalies. I will try other values later)
It was in perfect synch for a while.
South / North
Sep/Oct/Nov/Dec only go up to 2014 of course. 2005 was the peak AMO (approximately).
And its downhill to same kind of late 70s cold that made people think a new ice age was coming.
The good news. It should be another 25 years to reach bottom. The bad news. 2005 style warmth is 60 years away.
