get model temperatures that are below absolute zero or hotter than the Sun?

get just the same result for surface
temperature.
As we approach the targets given in Paris, the amount of precision we need on these allowable carbon budgets — to meet the
temperature changes — is going to
get sharper and sharper, and so we're going to need better climate
models to address those carbon budget issues.
When this
model is run with a standard, idealised global warming scenario you

The scientists
got a very similar result when they repeated their analysis with a different set of

There is also no attempt to tweak the

We've
got two lesson 1 parameters (two weights but which sum to one, plus the ad hoc scaling factor making a total of two free parameters), then we've
got one lesson 2 parameter (the mixed layer depth) and one lesson 3 parameter, the initial
temperature anomaly, making a grand total of 4 free parameters plus he
got to choose the data sets that he drove this
model with in the first place.
The
models are not tuned to
get the
temperature trend «right» (since it is clear that they don't!).
Even the admirable Revkin doesn't
get it quite right: On horizontal surfaces, observations and
modeling show a role for melting in both the baseline ablation and the sensitivity of ablation to precipitation and
temperature; melting is the dominant ablation mechanism on vertical ice cliffs; and though Kaser et al find «no evidence» about rising
temperatures, it is only because the in situ studies don't cover a long enough period to detect trends.
Well, for one thing we see climate
models that are as noisy as the
temperature record, yet as the errors reduce, it looks like the
temperature record
gets less noisy.
Also, from the same source: http://climateprediction.net/science/secondresults.php «Most
models still maintain a
temperature of between 13 and 14 Â °C, however some
get colder — these are not stable and the heat flux calculated in phase 1 was not correct to keep the
model in balance.»
You are saying that if the
temperature in Southern Greenland was going up like crazy, the «warmers» would say it can't be due to global warming because their
models show Southern Greenland won't
get very warm due to AGW.
Using this
model to forecast the
temperature in 2005 I
get an estimate of 0.35 C + / - 0.14 C, well below the recorded annomaly of 0.7 C. I am using the standard approach to estimating and forecasting using ordinary least squares (OLS).

In some cases, reviewers and / or editors supportive of mainstream views totally block important papers from being published; McKitrick, McIntyre and Herman had to completely rewrite their recent paper — showing that high tropical tropospheric
temperature trends for the last three decades produced by climate
models are inconsistent with observations — as a study of applying statistical methods developed in econometrics, and submit it to a journal with a more open - minded editor, in order to
get it published at all.
You really need to account for the vertical structure of
temperature (the lapse rate), and if you want your
model to
get a number of basic things right you need to include spectrally grey absorbers — plus the additional mixing in the troposphere (which depends on convection, and hence affects water vapour feedbacks) etc....
I guess the point of your posting was that IF we know the course of the actual forcing, climate
models can
get global
temperatures pretty well.
So, if some of these ideas on termination of glaciations are correct (ice - sheet
temperature, ocean circulation and CO2), and all of these are omitted from the current
model, it leaves open the possibility that a more comprehensive
model would
get a different result.
HOWEVER, when you apply the laws of physics to the new end state, ie globe warmed by a few degrees by GHGs, you
get a situation where the new Wiens law value (higher driving
temperature gives hotter energy spectrum out) and the new Stefan - Boltzmann value, (ie HIGHER energy out) disagree with the physical situation that the
model REQUIRES — ie energy out = 99.98 units which is LOWER.
Well, you can continue to heed the trumpets of fear from those whose
model projections can't even
get the

I haven't
got to the bottom of this yet, but there are several plausible explanations: (i) some of the simulations in the downloaded
models from the CMIP3 ensemble stop early, affecting the whole envelope of results, (ii) the use of common EOFs fail to capture large - scale
temperature patters that are too different from the past.
The claim to
get around the two problems of an geometric increase in error, and using absolute values of
temperature that are not Earth's, is the argument that the
model ensemble
got the heat transfer correctly in atmosphere and in the ocean.
But I am trying to
get the mindset turned around so that there is no attempt to fit the
temperature measurements to the
model, Only the
model can change.
The thing that really absolutely nailed it on for me was the fact that you simply could not
get a climate
model to give you the observed
temperature change withuot including greenhouse gases.
The modelers could consider varying the change i n forcing in a long series of simulations / samples from the
model population (4, 3.5, 3, 2.5 etc) until they
got some means consistently below the mean
temperature.
Anyway, the
models should have a high correlation perhaps 0.9 or 0.95 for what the IPCC is using them for — and they should
get the average
temperature of the earth right.
If you use well bounded
temperature for the past then thousand years to populate your
models, you would
get well bounded forecasts.
than the
model - expected slope of 0.2 C / decade which would
get us to a cumulative 3C rise of land
temperature by the year 2100.
Yet some kind of climate
model is indispensable to make future predictions of the climate system and IPCC has identified several reasons for respect in the climate
models including the fact that
models are
getting better in predicting what monitoring evidence is actually observing around the world in regard to
temperature, ice and snow cover, droughts and floods, and sea level rise among other things.
That said, largely from following discussions of this matter over at The Blackboard, I think if
temperatures stay relatively level for a couple more years, we can be pretty sure the
models have
gotten things way wrong.
They specifically used only
models that had
got the surface
temperatures correct.

If you take into account that virtually all the world's concrete and asphalt which causes the positive feedback of UHI (urban heat island) was made after 1940 you could tweak up the

temperature in Seattle does not
get pooled with the
temperature in Miami in the physical world, as it apparently does in the climate
models.
Here is an example of what I'm
getting at: * Climate change is a myth or conspiracy - The
temperature record is phony - the consensus is just politics * Climate change is unproven - The
models are wrong - One hundred years isn't enough evidence * It's not our fault - Volcano's emit way more CO2 - It could be natural variation * A warmer climate is nothing to worry about - It was warmer in the middle ages - A warmer climate is a good thing * Mitigation will destroy the economy - We don't know enough to act - Reducing fossil fuel will destroy us * It's too late or someone else's problem - Kyoto is too little too late - The US absorbs more CO2 than it emits This is very rough example, but if you think it is headed in the right direction, I'd be happy to go through your guide in more detail and come up with something concrete - just give me the word.
And the climate
models seem to
get the warming rate of sea surface
temperatures just right for the smallest portion of the global oceans, the extratropical Northern Hemisphere (24N - 90N).
