It's only "refreshing" for you because your understanding of AGW is based entirely on lazy straw man arguments.This was compensated for by the authors' actually having the courage and scientific integrity, in describing the period of cooling evidenced over the 1st decade of this century, to actually say, "At this time it cannot be decided whether this is a climatic shift during the first decade of the 21st century or if it represents decadal-interdecadal variability." How refreshing.
The question posed by the authors is entirely familiar to anybody who pays attention to the science.
Nothing here to suggest a coming ice age in Alaska.In summary, the long term observed warming of Alaska of about twice the global value, as expected by the increasing CO2 and other trace gases, is sometimes temporarily modified or even reversed by natural decadal variations.
Nothing here to suggest that science has previously ignored natural variability and effects.
What it shows is that the reason we understand climate change, including natural variability, is because of the work of scientists.
The reason the public may not understand this is because of misinformers like the Daily Mail, Goddard and Watts.
The reason you didn't understand it is your intellectual laziness and arrogance.
