Abstract

Be very careful about misreading model results

GCMs are not valid tools for examining how climate will change at the scale of physical assets

The desire of governments, regulators, standard-setters, and business to assess climate risk requires urgent understanding of the uses and limitations of climate model information

The IPCC has used very different scenario approaches over time
