How can the comparison of model projections since 1983 with the HadCrut4 surface and UAH lower troposphere temperatures (See Roy Spencer's chart) be anything other than «failure on an epic scale»?

p.s. To compare to Vahrenholt's forecast, here's a comparison of earlier model projections of global temperature for the IPCC (prediction with the CMIP3 model ensemble used in the 4th IPCC assessment report, published in 2007) with the actual changes in temperature (the four colored curves).

None of the large scale models used for the IPCC projections have been calibrated on the last millennium — because of uncertainty in the temperatures and uncertainties in the forcings.

Analysis of simple models and intercomparisons of AOGCM responses to idealised forcing scenarios suggest that, for most scenarios over the coming decades, errors in large - scale temperature projections are likely to increase in proportion to the magnitude of the overall response.

Global warming deniers * pull similar dirty tricks with the comparison of global temperature with model projections — for example, by plotting only the tropical mid-troposphere, and by comparing observations with the projections of scenarios which are furthest from reality.

The idea apparently persists that climate models are somehow built on the surface temperature records, and that any adjustment to those records will change the model projections for the future.

Do you think knowledge of «absolute truth» global average temperature would help to evaluate which model projections are closer to reality?

Is there a probability / odds level «threshold» if - you - will, whereby if the odds of «x» number of «y» years of observed temperature anomaly all occurring outside the confidence interval for a model's temperature projection, that it would be time for a paradigm shift in the particulars of the model, moreso than the normal tweaks?

In your graph of temperature measurements vs model projections, you discuss Scenario B, while it appears that Scenario C is almost identical to HadCrut3 and GisTemp.

But the evidence across a range of models shows that this is reasonable for the global mean temperatures and their projections.

Model projections suggest that although increased temperature and decreased soil moisture will act to reduce global crop yields by 2050, the direct fertilization effect of rising carbon dioxide concentration -LRB-[CO2]-RRB- will offset these losses.

If this heat has been lost to space, and the models have not accounted for it, it would seem to me that it must have an effect on the model «projections» because the non-equalibrium forcing has changed (the system has been reset at a lower temperature).

Wouldn't it be better if we put our efforts on accurate shorter term temperature projections, say what will happen in 6 months no more than a few years from now, check the models and brag about their accuracy or correct their failures, if the models are continuously correct all contrarian arguments die.

The answer is that if Lord Monckton had used the time - series model output, he would have had to admit that the IPCC temperature projections are still right in the ballpark.

Well, you can continue to heed the trumpets of fear from those whose model projections can't even get the temperature right globally, let alone regionally, or you can observe the various thermometers and realize the real Europe is cooling.

Raw climate model results for a business - as - usual scenario indicate that we can expect global temperatures to increase anywhere in the range of 5.8 and 10.6 degrees Fahrenheit (3.2 to 5.9 degrees Celsius) over preindustrial levels by the end of the century — a difference of about a factor of two between the most - and least - severe projections.

«Future projections based on theory and high - resolution dynamical models consistently suggest that greenhouse warming will cause the globally averaged intensity of tropical cyclones to shift towards stronger storms,» Knutson et al. (2010); Grinsted et al. (2013) projected «a twofold to sevenfold increase in the frequency of Katrina magnitude events for a 1 °C rise in global temperature.»

No, it translates to climate models can not accurately represent natural climate variability, which is why they can't project future global temperature at even the 2 % confidence level: «we find that the continued warming stagnation of fifteen years, 1998 - 2012, is no longer consistent with model projections even at the 2 % confidence level» — vonStorch (2013)

eg Water vapour feedback is not made up and then plugged into a model to make the temperature projections higher.

In summary the temperature projections of the IPCC — Met office models and all the impact studies which derive from them have no solid foundation in empirical science being derived from inherently useless and specifically structurally flawed models.

me warming of the earth's temperature, but that the observed rate of warming (both at the earth's surface and throughout the lower atmosphere) is considerably less than has been anticipated by the collection of climate models upon whose projections climate alarm (i.e., justification for strict restrictions on the use of fossil fuels) is built.

You can make them go down just as easily by increasing that aerosol forcing within it's uncertainty bounds and the earlier «ice - age» model projections did exactly that — using surface temperature as a target.

Here's an illustration: the Figure below shows what happens when the average ± 4 Wm - 2 long - wave cloud forcing error of CMIP5 climate models [1], is propagated through a couple of Community Climate System Model 4 (CCSM4) global air temperature projections.

Figure 6: Easterbrook's two global temperature projections A (green) and B (blue) vs. the IPCC TAR simple model projection tuned to seven global climate models for emissions scenario A2 (the closest scenario to reality thus far)(red) and observed global surface temperature change (the average of NASA GISS, NOAA, and HadCRUT4)(black) over the period 2000 through 2011.

What's lost in a lot of the discussion about human - caused climate change is not that the sum of human activities is leading to some warming of the earth's temperature, but that the observed rate of warming (both at the earth's surface and throughout the lower atmosphere) is considerably less than has been anticipated by the collection of climate models upon whose projections climate alarm (i.e., justification for strict restrictions on the use of fossil fuels) is built.

Thus Figure 1 depicts the IPCC TAR Scenario A2 temperature projection based on a simple climate model which was tuned to the seven Atmosphere - Ocean General Circulation Models (AOCGMs).

The analysis propagates climate model error through global air temperature projections, using a formalized version of the «passive warming model» (PWM) GCM emulator reported in my 2008 Skeptic article.

Ed Hawkins, of the University of Reading, in Britain, points out that surface temperatures since 2005 are already at the low end of the range of projections derived from 20 climate models.

Shows observed temperature (black and blue lines) model projections relative to 1986 - 2005 (light grey shading) and 2006 - 2012 (dark grey), and Met Office forecasts for 2015 and 2016 (green bars).

The mean high temperature projections for 2050 and 2100 were derived from a suite of 28 climate models (CMIP5 / Oak Ridge National Laboratory) under IPCC emissions scenario RCP8.5, averaged over November 22 - 28 for 2030 - 2049 and 2080 - 2099, respectively.»

A paper published in Nature Climate Change, Frame and Stone (2012), sought to evaluate the FAR temperature projection accuracy by using a simple climate model to simulate the warming from 1990 through 2010 based on observed GHG and other global heat imbalance changes.
