DESCRIPTION:Co-author: Sandro Vaienti (University of Marseille) \n\n By us
 ing new techniques originally developed for the analysis of extreme values
  of dynamical systems\, several long records of temperatures at different 
 locations are analysed by showing that they have the same recurrence time 
 statistics of a chaotic dynamical system perturbed with dynamical noise an
 d by instrument errors. The technique provides a criterion to discriminate
  whether the recurrence of a certain temperature belongs to the natural cl
 imate variability or can be considered as a real extreme event with respec
 t to a specific time scale fixed as parameter. The method gives a self-con
 sistent estimation of the convergence.\n
