Three years ago a cogent paper was published in the prestigious scientific journal Nature that was surprisingly candid in its rejection of the position that the substantial warming and sea ice reduction in the Arctic occurring since the late 1970s should be predominantly attributed to anthropogenic forcing.

Dr. Quinhua Ding and 6 co-authors indicated in their paper that internal processes — natural variability associated with planetary waves and the North Atlantic Oscillation — are drivers of the recent Arctic warming and sea ice reduction, concluding that “a substantial portion of recent warming in the northeastern Canada and Greenland sector of the Arctic arises from unforced natural variability.”

Since 2014, there have been several more scientific papers that have been published documenting the significance of natural forcing processes in the Arctic and how they may override a clear detection of an anthropogenic influence.But 2017 already seems to be an exception.  Papers that document the dominance of natural forcing — or that don’t even mention anthropogenic forcing as a factor in the Arctic climate processes — keep on rolling in.

As a case example, in a paper discussing the mechanisms involved in “Arctic amplification” and sea ice loss, Kim et al. (2017) never once mention anthropogenic forcing, or carbon dioxide, as mechanisms affecting the Arctic climate.  In fact, in citing several other authors, they acknowledge that the physical processes involved in the forcing of Arctic climate are “subject to debate” and remain “an open question.”   In other words, not only is the position that humans exert a dominant influence on the Arctic climate not “settled science”, the anthropogenic influence may be so muted a factor that it is not even worth mentioning in a paper discussing forcing mechanisms.
