A single annual temperature time series sampled from the ECHO-g millennial simulation.

White noise time series scaled to have standard deviations 1, 2 and 4 times the standard deviation of the temperature time series shown at the top of this post.

Time series created by combining the white noise in the figure on the left with the temperature time series plotted at the beginning of this post.  Correlations given in the plots are between the combined time series in the figure and the original temperature time series.
