Ice cores are high resolution paleoclimatic records which reveal very strong climate variations in the past. By spectral filtering and other time series analysis techniques we try to understand the underlying climate dynamics. The system has a strong component of fast fluctuating chaotic variation. On long timescales this acts as stochastic noise forcing the climate. Thus observed non-linearities, tipping points, can be seen in the record as response to the climatic noise.
