Galactic turbulence and paleoclimate variability

TL;DR

This study reveals that galactic turbulence influences Earth's paleoclimate variability over millennial time scales, showing Kolmogorov turbulence features that explain temperature fluctuations during ice ages.

Contribution

It provides evidence of galactic turbulence modulation in paleoclimate data and characterizes its Kolmogorov nature, linking astrophysical phenomena to climate variability.

Findings

Galactic turbulence modulates paleoclimate fluctuations.

Temperature fluctuations exhibit Kolmogorov turbulence features.

Galactic turbulence influences climate on millennial scales.

Abstract

The wavelet regression detrended fluctuations of the reconstructed temperature for the past three ice ages: approximately 340000 years (Antarctic ice cores isotopic data), exhibit clear evidences of the galactic turbulence modulation up to 2500 years time-scales. The observed strictly Kolmogorov turbulence features indicates the Kolmogorov nature of galactic turbulence, and provide explanation to random-like fluctuations of the global temperature on the millennial time scales.
