TL;DR: In this article, the authors examined nonlinear coupling among a number of important climatological variables, d 13 C, d 18 O and insolation, using mutual information and redundancy.

TL;DR: It is demonstrated that regional hydroclimates controlled by the Northern Hemisphere mid-latitude storm tracks and the African and South American Monsoons changed synchronously during the last 10 kyrs, arguing that these regional hydroclimate variations are connected and reflect the adjustment of the atmospheric poleward energy transport to the evolving differential heating of the Northern and Southern Hemispheres.

TL;DR: A critical review of key publications on the topic and statistical re-analysis of key records of global ice volume and African climate leads to three conclusions: (1) The Northern Hemisphere Glaciation was a gradual process occurring between ∼3.5 and 2.5 Ma, not a single event at ∼2.8 Ma or at any other time as discussed by the authors.

TL;DR: In this paper, a modified Grassberger-Procaccaccia algorithm was used to estimate the correlation dimension of the Henon map (Henon map) for global Plio-/Pleistocene climate variability, and the nonlinear least squares Gauss-Marquardt regression method was used instead of the linear least squares fit to the logarithmically transformed points.

TL;DR: This work searches for peaks in the sulfate time series from a Greenland ice core, whereas the background and variability reflect changing oceanic and other input, which may be difficult when background signal and climatic variability are time-dependent.
