The Gravitational Power Originating the Earthquakes and the Dansgaard-Oeschger Catastrophic Events

Dansgaard-Oeschger events: tipping points in the climate system

The largest variability in temperature over the last sixty thousand years is connected with Dansgaard-Oeschger events. Various prototype models have been proposed to explain these rapid climate fluctuations, but until now no observational constraint has been forwarded to choose between different theories. We assess the bimodality of the system reconstructing the topology of the multi-dimensiona...

A two‐parameter stochastic process for Dansgaard‐Oeschger events

[1] Various climatic processes are thought to evolve as rapid, shift‐like events, which points at the presence of nonlinear dynamics. Time series analysis of nonlinear processes, however, is not trivial, for example, because of the difficulty in coming up with a realistic random process as a viable null hypothesis. In this methodology paper we construct a basic two‐parameter process of shift‐li...

Limitations of red noise in analysing Dansgaard-Oeschger events

During the last glacial period, climate records from the North Atlantic region exhibit a pronounced spectral component corresponding to a period of about 1470 years, which has attracted much attention. This spectral peak is closely related to the recurrence pattern of DansgaardOeschger (DO) events. In previous studies a red noise random process, more precisely a first-order autoregressive (AR1)...
