Climate Science: Roger Pielke Sr. Research Group News » Emerging [Alleged] Arctic Amplification by Mark C. Serreze and Andrew P. Barrett

As climate scientists, we must constantly grapple with imperfect models and imperfect observations. The challenge is trying to make sense of both.

Check out this 1993 paper--with Mark Serreze's name on it: "Absence of evidence for greenhouse warming over the Arctic Ocean in the past 40 years"

In particular, we do not observe the large surface warming trends predicted by models; indeed, we detect significant surface cooling trends over the western Arctic Ocean during winter and autumn. This discrepancy suggests that present climate models do not adequately incorporate the physical processes that affect the polar regions.
