Journal ArticleDOI
On the Stochastic Nature of the Rapid Climate Shifts during the Last Ice Age
Peter D. Ditlevsen,Ove Ditlevsen +1 more
TL;DR: In this article, the transition from the warm interstadial to the cold stadials was analyzed and the distribution of waiting times between consecutive onsets was well fitted, assuming that the remaining residence time in each state is independent of the past.
Journal ArticleDOI
Molecular modeling of ethylene decomposition on platinum surfaces
TL;DR: In this article, a semi-empirical tight-binding scheme based on the extended Huckel theory is proposed to model the potential energy hyper-surface (PES) on which the energy minima are found.
Journal ArticleDOI
Contrasting scaling properties of interglacial and glacial climates.
Zhi-Gang Shao,Peter D. Ditlevsen +1 more
TL;DR: The unbroken scaling thus indicates that the DO events are part of the natural variability and not externally triggered, and that the glacial climate is dominated by the strong multi-millennial Dansgaard–Oeschger events influencing the long-time correlation.
Journal ArticleDOI
An independent test of methods of detecting system states and bifurcations in time-series data
TL;DR: In this paper, the authors present an independent test of recently developed methods of potential analysis and degenerate fingerprinting which aim, respectively, to identify the number of states in a system, and to forecast bifurcations.
Journal ArticleDOI
A conceptual model for glacial cycles and the middle Pleistocene transition
Istvan Daruka,Peter D. Ditlevsen +1 more
TL;DR: In this paper, a simple oscillator type model with two variables, a temperature anomaly and a climatic memory term, is presented, which reproduces the temporal asymmetry of the late Pleistocene glacial cycles and suggests that the MPT can be explained as a regime shift, aided by climatic noise, from a period 1 frequency locking to the obliquity cycle to a period 2-3 frequency locking.
