The statement regarding the Little Ice Age (LIA) and its relation to modern warming is incorrect at multiple points and contains poor logical reasoning in arriving at its conclusions. The assertion that the LIA resulted in cooling at all locations over the earth is incorrect. While scholarship indicates that average temperature may have cooled on a global or hemispheric level during the LIA, this averaging masks regional variances [Matthews and Briffa, 2005] LIA cooling was not uniform temporally or spatially [e.g. Ogilvie and Jonsson, 2001; Kreutz et al. 1997; Hunt, 2006]. Temporally, climate was not continuously cooler; multiple studies of the LIA, most notably Briffa’s [2000] dendrochronology dataset, indicate that the LIA was composed of both cold and warm periods, with several anomalously warm years [e.g. Jones and Briffa, 2001; Bradley and Jones, 1993; Oglivie and Jonsson, 2001; Matthews and Briffa, 2005]. Similarly, considerable spatial variation exists; multiple studies have observed that at a time when one region in a hemisphere was cooling, the temperature trend in another region was likely moving in the opposite direction [Matthews and Briffa, 2005; Hunt, 2006; Bradley and Jones, 1993]. One notable contention to the uniform cooling claim is Tasmania, where no net cooling occurred during LIA [Bradley and Jones, 1993]. Contradicting evidence aside, it is impossible to support the claim for a ubiquitous global cooling during LIA, as proxy record availability and
