In their paper, Lanfredi et al. [2003] raise several issues about our analysis of normalized difference vegetation index (NDVI) data for areas north of 30° N between 1981 and 1999. As we describe below, their comments represent a basic misunderstanding of the data, a misrepresentation of our work, or an anticipation of our recently published results. Here we address these issues in order in
which they are given by Lanfredi et al.
