They show that the test used by S&W on series with a long term trend will make them all appear similar, and that if the GTA and SFI are detrended the correlation disappears.

So the plot above is the “detrended” sequence length.

Our analysis shows that properly detrended, integrated solar are index is well described as an uncorrelated Lévy flight, while the detrended, integrated temperature anomaly record is consistent with a persistent fractional Brownian motion.

For the GTA, it turns out that if the time series is properly detrended the Hurst parameter 0.65 indicates that the steps are positively correlated, e.g changes in global temperature anomalies on a monthly basis are correlated at least a few steps out from any point and the series can be described as a fractional Brownian process.
