Eemian interglacial reconstructed from a Greenland folded ice core

Dorthe Dahl-Jensen, +132 more
- 24 Jan 2013 - 
TL;DR: In this paper, the North Greenland Eemian Ice Drilling (NEEM) ice core was extracted from folded Greenland ice using globally homogeneous parameters known from dated Greenland and Antarctic ice-core records.

Eemian interglacial reconstructed from a Greenland folded ice core (SCI)

Dorthe Dahl-Jensen, +133 more
TL;DR: The new North Greenland Eemian Ice Drilling (‘NEEM’) ice core is presented and shows only a modest ice-sheet response to the strong warming in the early Eemians, which was probably driven by the decreasing summer insolation.
Journal ArticleDOI

Observation of α‐stable noise induced millennial climate changes from an ice‐core record

TL;DR: In this article, it was shown that the fast time scale noise forcing the climate contains a component with an -stable distribution, and that abrupt climatic changes observed could be triggered by single extreme events.
Journal ArticleDOI

Tipping points: Early warning and wishful thinking

TL;DR: In this article, a high-resolution ice core record was used to identify the most pronounced changes observed, beside the glacial terminations, are the Dansgaard-Oeschger events, which strongly suggest that they are noise induced and thus have very limited predictability.
Journal ArticleDOI

Anomalous jumping in a double-well potential.

TL;DR: Noise-induced jumping between metastable states in a potential depends on the structure of the noise, and jumping triggered by single extreme events contributes to the transition probability for an alpha-stable noise.
