Miller et al.’s “Unprecedented Recent Summer Warmth in Arctic Canada”: Bad assumptions, poor logic, and contrary to other evidence of Arctic temperatures.

Occasionally, people ask me why I think popular claims for anthropogenic warming are bunk. The answer, dear reader, is that I read the scientific papers advancing such conclusions and compare the data presented to that from previous research that has been both peer-reviewed and reproduced by others, preferably with alternative methods. This reblogged article does likewise. Perhaps you ought read it.

Watts Up With That?

Dr. Don J. Easterbrook, Western Washington University, Bellingham, WA

Miller et al. radiocarbon dated 145 rooted tundra plants revealed by receding ice in the eastern Canadian Arctic and contend that it constitutes the first direct evidence that recent temperatures now exceed those of any century in the Holocene, including the Holocene Thermal Maximum. They further contend that (1) average summer temperatures of the last ~100 years were higher than any century in the past 44,000 years and suggest that present temperatures have not been exceeded in the past ~120,000 years, at or near the end of the last interglaciation, and (2) they conclude that this ‘unprecedented’ warming was caused by anthropogenic increases in greenhouse gases. So let’s look at some of the assumptions that form the basis for their conclusions and compare their conclusions to other Arctic data.
