TLDR
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.Abstract:
The last glacial period showed millennium scale climatic shifts between two dieren t stable climate states. The state of thermohaline ocean circulation probably gov- erns the climate, and the triggering mechanism for climate changes is random uctuation s of the atmospheric forcing on the ocean circulation. The high temporal resolution paleo- climatic data from ice-cores are consistent with this picture and a bi-stable climate pseudo-potential can be derived. It is found that the fast time scale noise forcing the climate contains a component with an -stable distribution. As a consequence the abrupt climatic changes observed could be triggered by single extreme events. These events are re- lated to ocean-atmosphere dynamics on annual or shorter time scales and could indicate a fundamental limitation in predictability of climate changes.

Fluctuation-dissipation: Response theory in statistical physics
TL;DR: In this paper, the relation between the relaxation of spontaneous fluctuations and the response to an external perturbation is discussed, and the connection of these works with large deviation theory is analyzed.

Stochastic resonance in the North Atlantic
TL;DR: In this article, the authors proposed a stochastic resonance hypothesis to predict a recurrence pattern between warm and cold modes of North Atlantic climate, which is consistent with the isotopic data from central Greenland ice cores but not with other models.

TL;DR: In this paper, the authors present a detailed stable isotope record for the full length of the Greenland Ice-core Project Summit ice core, extending over the past 250 kyr according to a calculated timescale, and find that climate instability was not confined to the last glaciation, but appears also have been marked during the last interglacial (as explored more fully in a companion paper), and during the previous Saale-Holstein glacial cycle.

TL;DR: In this article, the authors present records of sea surface temperature from North Atlantic sediments spanning the past 90 kyr which contain a series of rapid temperature oscillations closely matching those in the ice-core record, confirming predictions that the ocean must bear the imprint of the Dansgaard-Oeschger events.
