"Orbital-scale influence on the occurrence and magnitude of abrupt climate change: an application of extreme value theory to paleoclimate observations"

Thursday, October 17, 2013 10:00 AM - 11:00 AM

The occurrence and magnitude of abrupt temperature changes in the last 250,000 years are analyzed using time-dependent statistical models. A non-homogeneous Poisson process is used to model the frequency of abrupt events and a time-dependent version of the generalized Pareto distribution to analyze the climatic variability of the magnitude. The models are parameterized in terms of the Milankovitch-forced covariates. The statistical approach allows the quantification of the eccentricity, precession, obliquity and insolation influence in the warm and cold abrupt climate changes.
