The
current version of the figure gives the impression that the IPCC expected temperature to warm continuously year on year, which of course was not the expectation — the projections shown here are just the long - term trend either from

So it shouldn't be used to rule out whether or not a particular observed value is consistent with
model expectations, but does give you some guidance as to just how far from the
average model expectation the
current trend lies (a cherry picker is not usually worried about the finer details of the former, but, instead, the coarser picture presented by the latter).
Current GCM
models may have realistic - seeming weather patterns, but are totally incapable of producing phenomena that look like the Holocene (Little Ice Age, Medieval Warm Period, Roman Warm Period, Holocene Optimum, the steady decline of temperature on

«Climate science» as it is used by warmists implies adherence to a set of beliefs: (1) Increasing greenhouse gas concentrations will warm the Earth's surface and atmosphere; (2) Human production of CO2 is producing significant increases in CO2 concentration; (3) The rate of rise of temperature in the 20th and 21st centuries is unprecedented compared to the rates of change of temperature in the previous two millennia and this can only be due to rising greenhouse gas concentrations; (4) The climate of the 19th century was ideal and may be taken as a standard to compare against any
current climate; (5) global climate
models, while still not perfect, are good enough to indicate that continued use of fossil fuels at projected rates in the 21st century will cause the CO2 concentration to rise to a high level by 2100 (possibly 700 to 900 ppm); (6) The global
average temperature under this condition will rise more than 3 °C from the late 19th century ideal; (7) The negative impact on humanity of such a rise will be enormous; (8) The only alternative to such a disaster is to immediately and sharply reduce CO2 emissions (reducing emissions in 2050 by 80 % compared to today's rate) and continue further reductions after 2050; (9) Even with such draconian CO2 reductions, the CO2 concentration is likely to reach at least 450 to 500 ppm by 2100 resulting in significant damage to humanity; (10) Such reductions in CO2 emissions are technically feasible and economically affordable while providing adequate energy to a growing world population that is increasingly industrializing.
However, Solanki et al made the same point as we do: «This comparison shows without requiring any recourse to
modeling that since roughly 1970 the solar influence on climate (through the channels considered here) can not have been dominant» (Solanki et al., 2003), and: «Although the rarity of the
current episode of high
average sunspot numbers may indicate that the Sun has contributed to the unusual climate change during the twentieth century, we point out that solar variability is unlikely to have been the dominant cause of the strong warming during the past three decades.»

None of these could have been caused by an increase in atmospheric CO2,
Model projections of warming during recent decades have greatly exceeded what has been observed, The

The
models do reproduce the 20th century, and even the last 1000 years globally
averaged reasonably well, observational data of forcing factors permitting, and they do this with the same physics that produce 2xCO2 sensitivity as 2.9 oC There is another essential factor in looking at
current T rise vs CO2 forcing and that is the global dimming phenomenon.
Ome would expect that our mathematical
models would by now be able to faithfully reproduce
current average global temperatures, but this is not so — the IPCC
models all exaggerate their predictions, also indicating a lack of understanding and validation of climate
models.
Probability distributions for
average future changes in surface temperature and precipitation, for instance, may be within reach, because the main processes expected to drive such changes are captured in the
current generation of climate
models.
