DESCRIPTION:We review recent results where new averaging approaches are de
 veloped and applied in the context of systems with multiple time scales an
 d fat tails  and in non-autonomous multiple scale systems with oscillatory
  forcing.  These types of systems appear in a variety of higher dimensiona
 l climate models\, as well as in other areas of application.  The results 
 open new research directions\, with potential to better address questions 
 like: which mechanisms contribute to fat-tail statistical properties appea
 ring in (climate) data?  What are reasonable approximations for multiple s
 cale systems with non-Gaussian behaviour?  How can these approximations pr
 ovide insight into the dynamics of larger models\, such as parameter range
 s with large variability\,  tipping\, or reversibility?   Some areas for f
 urther research are discussed.
