The warming of the Arctic is partly due to natural causes, claims a new study in the journal Nature.
It is difficult for the true believers to give up the paradigm that human-caused global warming plays a role in turning the Arctic into slushpile. However, since average global temperatures have not increased for ten years (see previous entry of this blog), the warming in the Arctic must be matched by cooling elsewhere on the globe. By definition, it is not global warming, since the globe is not warming, on average.
In this context, the warming of the Arctic must be a local condition, caused by natural factors, as cited in the new study.
If polar bears are suffering, we are not to blame. Mother Nature is.
