I wonder if the cold across Alaska, Arctic Canada, Greenland and the Barents Sea can also be attributed to climate change?

I notice that the Met Office have just put out an article ‘attributing’ the unprecedented warmth of the last six months in Siberia to climate change, so I thought I would take a closer look. As most of my readers well know I don’t take anything at face value, especially when it must follow that the the same circulation patterns that caused the warming across Siberia, were also responsible for the colder than average conditions across Alaska, Arctic Canada, Greenland and the Barents Sea? Admittedly the negative anomalies are not on the same magnitude as the 5.5°C positive anomalies across Siberia, but for a six month period over such a large area it’s hardly insignificant either. It’s logical that even in these days of AGW that for every colder than average region on an anomaly map there is equally a spread of cold region, but of course doing some rapid research into attributing colder than average conditions would hardly fit with the ‘global heating’ that’s currently going on. The words bandwagon and jumping spring to mind when I see any article concerning climate attribution who seem to pop up when not expected to deliver another verdict just like in that classic Monty Python sketch.
