Demetris Koutsoyiannis says:
I am glad to see Shaun’s and Daniel’s paper and I congratulate them–particularly for the catchy title. You may also see an older version of negation of the same dictum in my paper “Hurst-Kolmogorov dynamics and uncertainty” (see http://itia.ntua.gr/1001/ for the 2011 paper – page 492 or pages 23-24 of the preprint; see also http://itia.ntua.gr/944/ for the 2010 predecessor presentation, slide 45).

Philip Bradley says:
Seems rather trivial to me.
Temperature fluctuations increasing to 10 days is a function of the size and speed of movement of the mid-latitude high pressure systems. Winds are from the north on one side and the south on the other side.
As for predicting macroweather. Here in the southern hemisphere on the western side of Australia, the 10 day forecasts are pretty good. When Pielke says macroweather forecasts aren’t good, I suspect he is referring to the more chaotic NH weather systems.
