This paper presents results concerning the nonlinear analysis of the Earths Northern Hemisphere mean annual land temperature reconstructions for the time period of 713 2004. The nonlinear analysis consists of the application of several filtering methods, the estimation of geometrical and dynamical characteristics in the reconstructed phase space, techniques of discrimination between nonlinear low dimensional and linear high dimensional (stochastic) dynamics and tests for serial dependence and nonlinear structure.
