Journal ArticleDOI
Contrasting atmospheric and climate dynamics of the last-glacial and Holocene periods
TL;DR: In this article, the authors report the results of an analysis of temporal trends over the past 91,000 years in the oxygen isotope signatures of a high-resolution ice-core record from Greenland, which provides direct evidence that atmospheric circulation during the last glaciation was more turbulent than it is today.
Journal ArticleDOI
The DO-climate events are probably noise induced: statistical investigation of the claimed 1470 years cycle
TL;DR: In this article, the authors present statistical significance tests of the observed 1470 years cycle in the recurrence of the Dansgaard-Oeschger (DO) events observed in the Greenland ice cores.
Journal ArticleDOI
Retrieving a common accumulation record from Greenland ice cores for the past 1800 years

TL;DR: In this paper, a statistical model has been developed to estimate the common climate signal in the different accumulation records through optimization of the ratio between the variance of the common signal and of the residual.
Journal ArticleDOI
The Recurrence Time of Dansgaard–Oeschger Events and Limits on the Possible Periodic Component
TL;DR: In this article, an objective criterion for defining Dansgaard-Oeschger (DO) events is achieved by comparing the high-resolution isotopic records from the Greenland ice core Project (GRIP) and the North Greenland Ice Core Project (NGRIP) ice cores, the common climate signal in the records has been approximately separated from local noise.
The recurrence time of Dansgaard-Oeschger events and limits on the possible periodic component
TL;DR: In this article, the authors compared the high-resolution isotopic records from the Greenland Ice Core Project (GRIP) and the North Greenland ice core Project (NGRIP) ice cores and obtained an objective criterion for defining Dansgaard-Oeschger (DO) events.
