Greenland Temperatures & The AMO

By Paul Homewood





It’s not new, but it’s worth going over it again.

We have seen how Greenland temperatures rose sharply in the 1920s, and remained at levels similar to the last decade until the 1960s, when they fell equally sharply. This change in climate is closely interlinked with the Atlantic Multidecadal Oscillation (AMO), which switches from cold to warm phase, and back again, roughly every 50 to 60 years:




If we put the temperature and AMO graphs together the correlation is immediately obvious:




(I have centred the the 10-year average temperatures, to align with the smoothed AMO trends, which are also centred.)

What is significant about the last few years is that Greenland temperatures have begun to fall despite the AMO flatlining.

It is absolutely clear that Greenland temperature trends are determined by the AMO, and that carbon dioxide has little or no effect at all.
