This data set contains data on distribution records and associated climate variables on species in three large phylogenetic clades of Australian skinks. The data was obtained from the Atlas of Living Australia (http://www.ala.org.au/) in October 2011 by downloading all museum records (latitude, longitude, elevation) for the species of interest as well as values from different climate layers at species' occurrence points. Climate layers used were Temperature - annual mean ("Bio01"; Hijmans et al. 2005), Temperature - max absolute mean max (Williams et al. 2010) and Temperature - min absolute mean min (Williams et al. 2010). The data was edited to exclude incomplete records and outliers far outside the known range of species. The data was used to test the applicability of the Climatic Variability Hypothesis, i.e. that species from more thermally variable habitats achieve greater range extents, in Australian skinks. Summarized data used for analyses and figures used in the associated publication are included in the data set. For details on references and analyses, refer to the associated publication.
