DESCRIPTION:The case is made for a partially stochastic reformulation of t
 he\ngoverning equations in future-generation climate prediction models.\n\
 nFirstly\, a guiding characteristic of the scientific method is an ability
 \nto characterise and predict uncertainty\; individual climate models are\
 nnot currently able to do this. Secondly\, through the effects of\nnoise-i
 nduced rectification\, stochastic-dynamic parametrisation may\nprovide a (
 poor man's) surrogate to high resolution in reducing model\nbias. Thirdly\
 , stochastic-dynamic parametrisations may be able to take\nadvantage of th
 e inherent stochasticity of electron flow through certain\ntypes of low-en
 ergy computer chips\, currently under development.\n\nThese arguments have
  particular resonance for next-generation\nEarth-System models\, which pur
 port to be comprehensive numerical\nrepresentations of climate\, and where
  integrations at high resolution\nmay be unaffordable.
