There are two classes of uncertainty in models — one is the systematic bias in any particular metric due to a misrepresentation of the physics etc, the other is uncertainty related to weather (the noise).

This is not simply the uncertainty in estimating the linear trend, but the more systematic uncertainty due to processing problems, drifts and other biases.

Clearly more analysis will clarify the uncertainties in the ocean heat estimates — which are very large and, I believe, may be understated in the Lyman et al paper since they address random but not systematic sources of error.

Because the differences between the various observational estimates are largely systematic and structural (Chapter 2; Mears et al., 2011), the uncertainty in the observed trends can not be reduced by averaging the observations as if the differences between the datasets were purely random.
