I'm not «arguing for
large uncertainty bars».
Not exact matches
The
large error
bars on that number inject
uncertainty into our projections of the effects of climate change — from changing storm patterns to sea level rise.
The error
bars in state - of - the - art SST compilations take into account such sampling
uncertainties, and indeed they become
larger back in time, especially the earliest decades (1850s - 1870s) in part due to the fact that there is substantial eddy variance.
In the end, I would hypothesize that the result of the freeing of data and code will necessarily lead to a more robust understanding of scientific
uncertainties, which may have the perverse effect of making the future less clear, i.e., because it will result in
larger error
bars around observed temperature trends which will carry through into the projections.
The «true» error
bars should be slightly
larger given the
uncertainty in the annual estimates themselves.
Having Santer show here that the mismatch between model and data for the troposphere and stratosphere is just another example of a new
uncertainty or
larger error
bar.
Where I have some difficulty is reconciling the narrow error
bars with Stephens et al. (2012) who state, «The current
uncertainty in this net surface energy balance is
large, and amounts to approximately 17 Wm — 2.
This is a
large shift, and the reaction to it is becoming predictably stronger as her
uncertainty error
bars go down while at the same time she makes this very rigid, almost intolerant, view more public.
But if we question it too hard we would need to either strip out every error
bar and
uncertainty limit from every paper without a known prior, or put
large horror warnings against each one stating that these error limits are the result of a subjective judgement of the authors.
I am fairly sure their error
bars don't take these a priori
uncertainties into account, but they have a lengthy discussion that says aerosols could conceivably have a
large effect on their results if correlated with surface temperature.
