nonstationarity

The first reason consists of the general nonstationarity climate, in particular during the period used for a calibration.

An Excellent Sonechkin Comment « Climate Audit 2007

However, our method cannot deal with nonstationarity even though the normalization of the weights in the OA procedure minimizes the distortion of the trends in the data.

The word “trend” often is used to imply a nonstationarity in the stochastic process from which observed number of hurricane arrivals are a realization.

The debate over whether hurricane statistics show signs of nonstationarity is to me far more interesting and relevant than the absence or presence of a trend.

In this respect it is not possible to infer nonstationarity or stationarity merely from data.

Juckes cites Wahl and Ammann « Climate Audit 2006

I just thought I would supply a concrete and relevant example of how such a quadratic response to temperature is not only real, but could lead to time-series nonstationarity that violates assumptions made in the inferential leap one takes in going from calibration to reconstruction.

WSJ: House Energy report on the "mutual admiration society" « Climate Audit 2006

Apparent temporal nonstationarity in the biological response of trees to climate might be a function of changes in climate itself [Vaganov et al., 1999; Aykroyd et al., 2001], although caution is necessary since this could also arise stochastically [Gershunov et al., 2001].

Of course, any nonstationarity is likely to be a response to some kind of recent anthropogenic forcing
