«In reality climate models have been tested on multicentennial time scales
against paleoclimate data (see the most recent PMIP intercomparisons) and do reasonably well at simulating small Holocene climate variations, and even glacial - interglacial transitions.
In order to predict future changes in climate, scientists verify and refine their models
against paleoclimate data from the ice cores Taylor and others pull up.

Even issues which are typically taken to be the sign of a more legitimate skepticism (like arguing for a low sensitivity), are now constrained by
data and
paleoclimate evidence, and mechanisms that could cause such model errors or misinterpretation of the paleo - record need to be shown by those who argue so confidently
against it.
«It is unlikely that coastal cities or low - lying areas such as Bangladesh, European lowlands, and large portions of the United States eastern coast and northeast China plains could be protected
against such large sea level rise,» states a report co-authored by Hansen, titled «Ice Melt, Sea Level Rise and Superstorms: Evidence from
Paleoclimate Data, Climate Modeling, and Modern Observations that 2 °C Global Warming is Highly Dangerous».
however, simulation of a broad range of
paleoclimates (and verification
against whatever paleo
data is available, given all the uncertainties, can help here.
