As can be seen your graph, our climate models make a wide range of predictions (perhaps 0.5 - 5 degC, a 10-fold uncertainty) about how much «committed warming» will occur in the future under any stabilization scenario, so we don't seem to have a decent understanding of these processes.

In deference to the unpredictable nature of attempting to forecast global climate (and as an attempt to avoid mistakes previously made) the panel was more cautious than it was in past reports in making predictions for the future.

If you were to produce a chaotic model using the above, I would venture a prediction that the above former were the massive attractors about which we could make some decent predictions about the future but that the latter human produced CO2 inserted into our atmosphere would leave us with hopelessly inadequate and wrong predictions because CO2 contributed by man is not an attractor of any significance in the chaotic Earth climate system nor is CO2 produced by man a perturbation that would yield any predictive ability.

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.

To equate climate models with «bad» science must be understood to be an attempt to undermine any scientific justification for climate change policies because models are needed to make predictions about the future states of complex systems.

The researchers used recent historical data and not climate modeling, so the study does not make any future predictions, but Swain says the findings appear to be consistent with other climate research that reveals there is little change in average precipitation, but an increase in the amount of very wet or very dry periods.

-- Muller believes humans are changing climate with CO2 emissions — humans have been responsible for «most» of a 0.4 C warming since 1957, almost none of the warming before then — IPCC is in trouble due to sloppy science, exaggerated predictions; chairman will have to resign — the «Climategate» mails were not «hacked» — they were «leaked» by an insider — due to «hide the decline» deception, Muller will not read any future papers by Michael Mann — there has been no increase in hurricanes or tornadoes due to global warming — automobiles are insignificant in overall picture — China is the major CO2 producer, considerably more than USA today — # 1 priority for China is growth of economy — global warming is not considered important — China CO2 efficiency (GDP per ton CO2) is around one - fourth of USA today, has much room for improvement — China growth will make per capita CO2 emissions at same level as USA today by year 2040 — if it is «not profitable» it is «not sustainable» — US energy future depends on shale gas for automobiles; hydrogen will not be a factor — nor will electric cars, due to high cost — Muller is upbeat on nuclear (this was recorded pre-Fukushima)-- there has been no warming in the USA — Muller was not convinced of Hansen's GISS temperature record; hopes BEST will provide a better record.

«In terms of how we should think about climate change prediction in the future, reducing emissions and so on, it really wouldn't make much of a difference.»

In this final section, I will try to make estimates of what subcap methane emissions may mean for future climate change; more as a speculative basis for discussion rather than an authoritative prediction.

This raises an interesting question, which is how should the IPCC (or anybody else for that matter) falsify hypothesis II and III, which although they are at least plausible, make no testable predictions, unlike hypothesis I.

A rational public and private sector response to the threat of storm damage in a changing climate must therefore acknowledge scientific uncertainties that are likely to persist beyond the time at which decisions will need to be made, focus more on the risks and benefits of planning for the worst case scenarios, and recognize that the combination of societal trends and the most confident aspects of climate change predictions makes future economic impacts substantially more likely than does either one alone.
