David Williamson, an epidemiologist at Emory University in Atlanta, says that the researchers don't furnish the usual indicators of statistical significance for their projections, such
as error bars.
The ensemble would lose all predictive power regardless of what happened to measured global temp,
as the error bars would be huge.

as an error bar.

As we have discussed previously, the last glacial period is a good example of a large forcing (~ 7 W / m2 from ice sheets, greenhouse gases, dust and vegetation) giving a large temperature response (~ 5 ºC) and implying a sensitivity of about 3ºC (with substantial
error bars).
Given the noise level, a trend 75 %
as large, would still be within the
error bars of the observation (i.e. 0.18 + / -0.05), assuming the transient trend would scale linearly.
The statistical significance is, however, still limited
as the large
error bars suggest.
Error bars represent one standard deviation

as the prequels.

As for «overlapping
error bars», this is a reasonable heuristic for this level of conversation — better CALCULATIONS can be found in Santer et al, 2008 (see how annoying that is?).
With
error bars provided, we can use the PIOMAS ice volume time series
as a proxy record for reality and compare it against sea - ice simulations in global climate models.
So there the
error bars are -1 K and +1.5 K. Annan & Hargreaves give a means to narrow this range somewhat and I think they give 2.8 K
as most likely.
Mark, by «VERY GOOD» do you mean the reliability, variances and
error bars of measuring average global mean temperatures and CO2 mixing ratios over the past 150 years is about
as good
as measuring your height over the past 30 years?
MBH on the other hand used different networks for different periods, hence the
error bars changed
as the networks get smaller further back in time.
Given the noise level, a trend 75 %
as large, would still be within the
error bars of the observation (i.e. 0.18 + / -0.05), assuming the transient trend would scale linearly.
And yes, those models are uncertain, with
error bars greater than zero:
as with any prediction of future events, you inherently can never be certain you're right until those events have already occurred.
[Response: If you restricted the analysis to 1988 to 2000 (13 years instead of 23 years of 1984 - 2006), no trends are significant in the obs or scenario B (scenario A is and scenario C is marginally so), although all
error bars encompass the longer term trends (
as you would expect).
More understanding has revealed some additional weaknesses in the earlier conclusions leading to the outcome that the
error bars are
as wide
as they were before.
As the adjacent chart shows, the reported 2014 HadCRUT4 (HC4) global temperature with its estimated
error bars (± 0.1 °C) may have been the warmest, and then again... there are 15 prior years that may have been warmer when considering all the
error bar implications.
A few
error bars have gotten smaller but new ones have been found
as is often the case in science.
If,
as I think we should, we implicitly place very wide
error bars on the 3 scenarios, then the current temperature record would fall comfortably within the
error bars of all 3 scenarios.
(The «I think» was because I was hoping to extricate myself from CE for a while to finish off a paper explaining why climate sensitivity
as currently defined can neither be measured nor estimated with an
error bar less than 1 C per doubling, and proposing a different definition that shrinks the
error bar by an order of magnitude.
As you mentioned gravity changes due to many causes, also orbital drift and large guesses with potential biases make the estimates of total ice volume have very large
error bars.
As others have pointed out, contrary to what I said, this graph does have
error bars.
Even todays» measurements are so screwed with, the
error bars are meaningless
as well.
That would be true only with
error bars as wide
as goal posts.
We take 1 SD of the values of A˜m, obs over 1980 — 2013
as a representative measure of the
error bars for this quantity.
Keep in mind there are
error bars around this estimate, just
as there are in previous studies by Bokyoff using sampling techniques and every other media analysis previously published that uses sampling techniques.
The
error bar on ECV total ozone data (δTOC) shall be assessed and expressed
as the percent relative difference with respect to correlative measurements of reference.
There is also a related phenomenon, whereby scientists are viewed
as being in
error because their theories are judged wrong, when actually, their theories were bounded by the such qualifications
as confidence intervals and
errors bars.
But many concerns appear: (1)
error bars should be growing
as long
as we move to the past, (2)
error bars should be much greater than they are, (3) the estimated value for averaged temperature anomaly is basically fictitious.
When the ice conditions in spring are used
as an indicator of what may happen several months later in September, there is a need to significantly raise the
error bar considering the significant variability of weather and climate.
Another paper criticized Wentz's analysis because he did not consider other factors which play a role in precipitation such
as global brightening during the period of study; and the
error bars in Wentz's estimate of the evaporation rate increase was considerable.
The Best study shows
error bars of 2 Degrees C which surely makes it useless
as any sort of scientific measure?

as the average of 100 more or less normally distributed points in the left slide, the
errors bars shrink by a factor of sqrt (100) = 10.
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.
A decadal average is just
as useful and has smaller
error bars in addition to removing sunspot cycles quite well.
Error bars larger than the effect being measured tend to be taken
as an argument for inaction — which, in fact, they are.
Bearing in mind their previous hubris about short - term cycles being manmade, their gross, unproven assumption about CO2
as a climate driver and the fact that the signal is far less than the
error bars in the noise then why would anyone think that the long - term trend is anything other than just a separate upswinging natural cycle?
Ice thickness is more difficult, and I would assign greater
error bars, but the increase is quite remarkable, and,
as Willis recently pointed out, while the exact m = thickness may be disputable, the method used is consistent, therefore the change documented is true relative to the past, even if the exact value is not known.
Right: global ocean heat - content (HC) decadal trends (1023 Joules per decade) for the upper ocean (surface to 300 meters) and two deeper ocean layers (300 to 750 meters and 750 meters to the ocean floor), with
error bars defined
as + / - one standard
error x1.86 to be consistent with a 5 % significance level from a one - sided Student t - test.
