In addition, model intercomparison studies do not quantify the range of uncertainty associated with a specific aerosol process, nor does this type of
uncertainty analysis provide much information on which aerosol process needs improving the most.

Further
analysis of the impacts of policies on prices and bills, including
analysis on households medium - sized businesses and large energy intensive users and a breakdown by individual policy, will be published later this year alongside the Annual Energy Statement and should
provide more detail on the
uncertainty surrounding the true cost of the Government's policies.
The study
provides sensitivity
analyses of key model assumptions and starting data
uncertainty, indicating that the UN projections may have too small a range of
uncertainty.
This paper presents a review of existing literature on emission factors, emission data collection techniques, and analytic approaches; presents the results of SAIC's
analysis of available CO2 and CH4 GHG emission data from chassis dynamometer tests of heavy - duty vehicle exhaust; and
provides suggestions for further reducing this
uncertainty.
Maybe too simplistic a methodology, but given the continued
uncertainties around the operations and governance at WCG, the economy in general and healthcare in particular, I don'think any complex
analysis will
provide more insight.
Such determinations require careful, quantitative
analyses involving forcings estimates and reconstructions, and are fraught with limitations owing to
uncertainties in both the forcing estimates and reconstructions — an excellent discussion is
provided in this manuscript by Waple et al and references therein.
We can apply my simpler bias
analysis (which we can now see is limited in that it does not
provide an
uncertainty estimate for the estimated bias) to HadCRUT3 / 4.
Statistical
analysis by Lewandowsky et al. finds that, contrary to our intuition, «increasing
uncertainty is necessarily associated with greater expected damages from warming,
provided the function relating warming to damages is convex.»
Some excerpts are
provided from both of these papers, to which I will refer subsequently in my
analysis and discussion of their treatment of
uncertainty.
It is hoped that
providing these 100 realisations in a form identical to the median estimate will encourage users to explore the sensitivity of their
analysis to observational
uncertainty with little extra effort.
With
uncertainty you need to re-evaluate your plans, hedge risks,
provide for flexibility... As noted here S cenario
analysis is component of a real planning effort.
Too bad Annan didn't understand my talk, since it was targeted particularly at people like him who are pushing the idea that CO2 sensitivity is 3C http://www.jamstec.go.jp/frsgc/research/d5/jdannan/probrevised.pdf and think that Bayesian
analysis can actually
provide such an answer in the face of such large
uncertainty.
HadISDH
provides values for the variables and their
uncertainties for 5 ° x5 ° grid squares, based on direct
analysis of quality - controlled station data.
In summary, given the large
uncertainties, I am unconvinced by Annan and Hargreave's
analysis in terms of
providing limits to the range of expected climate sensitivity values.
Mann then asserted that MBH98 had
provided «
provided detailed calibration and verification statistics that establish the skill in our reconstruction» together with
uncertainties calculated using «rigorous
analysis of the calibration and cross-validation residuals».
Of course, we have in, our own work
provided detailed calibration and verification statistics that establish the skill in our reconsruction in capturing the details of both the modern instrumental record, and independent, withheld earlier instrumental data (19th century and, more sparsely, 18th century), and we publish
uncertainties that are based on rigorous
analysis of the calibration and cross-validation residuals.
There was no attempt to
provide an accurate assessment of
uncertainties in satellite data, or to give a complete and balanced
analysis of the reasons for short - term differences between modeled and observed warming rates.
We believe that by
providing thorough written
analysis, recommended solutions, advice on negotiation, and a shoulder to lean on, we can turn fear and
