DESCRIPTION:Prof. Martin BENISTON  (Institute for Environmental Sciences\
 , The University of Geneva)\nClimate models have been the focus of much at
 tention in the past three decades\; indeed\, they have been instrumental i
 n highlighting the causes and consequences of anthropogenic climate change
 \, and their results have largely contributed to climate policy and\, in p
 articular\, the 2015 Paris Climate Accord. In this talk\, we shall briefly
  outline the underlying concepts of climate models\, in particular the rep
 resentation of fluid mechanics\, thermodynamics and atmospheric radiation 
 in atmospheric models\, as well as the coupling of sub-models that are des
 igned to link the interacting components of the climate system (the atmosp
 here\, oceans\, cryosphere\, and biosphere). Examples will be given of par
 ametric schemes (i.e.\, physically based simplifications of various proces
 ses that help speed up computational resources)\, and some results will be
  provided for possible future climate scenarios. The talk will conclude wi
 th an overview of the successes and limits of these highly complex modelin
 g systems.\n
