What to do? Does science have a role?

A new generation of integrated assessment models of climate change policies is needed to capture the basic dynamical processes that govern the required transformation of the present fossil-based global economic system to a sustainable decarbonized system. After an overview of the abatement technologies and policy instruments that are already available and able today to achieve the transformation, three examples are presented of typical actor-based, system-dynamical models that are able to simulate some of the key dynamics of the transition processes. In addition to developing a new hierarchy of integrated assessment models, scientists need also to better educate the public and policy makers on the wide-reaching implications of the inherent inertia of the climate system.
