This is not an isolated problem but one of worldwide interest because each country has concerns about their food security.The Agricultural Model Intercomparison and Improvement Project (AgMIP) was developed to evaluate agricultural models and intercompare their ability to predict climate impacts.

Statements such as «They come to believe models are real and forget they are only models» reveals he has never had a conversation with a climate modeller — our concerns about ice sheets for instance come about precisely because we aren't yet capable of modelling them satisfactorily.

What really concerns me is that I've read a lot about climate models not being able to replicate the magnitude of abrupt regional temperature changes in the past, and Raypierre has said here that he fears that past climate records point towards some yet unknown positive feedback which might amplify warming at the northern latitudes.

What has always concerned me about the majority of the climate models are reliance on prior climatology and not looking for new patterns.

However, that his statement can be quoted in a major US newspaper says much about the level of public knowledge concerning climate change and the models used to try and understand it.

• Lack of formal model verification & validation, which is the norm for engineering and regulatory science • Circularity in arguments validating climate models against observations, owing to tuning & prescribed boundary conditions • Concerns about fundamental lack of predictability in a complex nonlinear system characterized by spatio - temporal chaos with changing boundary conditions • Concerns about the epistemology of models of open, complex systems

I find concerned liberals are loath to talk about how consistently wrong climate models have been or about the «pause» in global warming that has gone on for over fifteen years, while climate skeptics avoid discussion of things like ocean acidification and accelerated melting in Greenland and the Arctic.

This brings to me to my first concern about Mike's model of recent climate.

I defer to the climate modellers on the question of what levels of temperature rise to be concerned about and how to do the modelling.

In particular, I hope that impugning models as a means of rejecting serious concerns about the future consequences of anthropogenic CO2 emissions will be seen as misguided — based on the false assumption that without models, the edifice of climate prediction will collapse.

I remain very concerned about abrupt climate change, but I am also working to demonstrate that if you accept the IPCC framing of the climate change problem, e.g. «forced», that models are over sensitive and the sensitivity is lower than inferred from climate models.

THAT's the climate model everyone should be concerned about.

Judith raises concerns about the epistemology of models for open, complex systems, distinctly indefinite... and then... adopting an uncertain global climate policy that could possibly produce «losses that throw mankind into economic, social and environmental bankruptcy.»

Even just acknowledging more openly the incredible magnitude of the deep structural uncertainties that are involved in climate - change analysis — and explaining better to policymakers that the artificial crispness conveyed by conventional IAM - based CBAs [Integrated Assessment Model — Cost Benefit Analyses] here is especially and unusually misleading compared with more ordinary non-climate-change CBA situations — might go a long way toward elevating the level of public discourse concerning what to do about global warming.

You aren't going to make concerns about anthropogenic climate change vanish by attacking the models.
