John Christy, Anthony Watts, et al. Release Analysis of Thermometer Siting and NOAA Temperature Adjustments
Comment: This paper introduces a finer method of classifying sites where temperatures are recorded. Many sites are affected by the presence of asphalt (either from roofs, tarmacs, or parking lots), buildings, and even exhaust from cars and AC units. These sites receive a lower compliance rating. Yet climate scientists still insisted that the overall trend remained the same for good or bad surface stations. In this paper, a better classification of sites is used. This classification is applied to historic data sets. The signal for good sites give a very slight warming over 3 decades. The poor sites give a greater warming trend. The adjustments made to the data later all conform to, and even exceed, the trends from the poor sites. See figure above, and the paper – in particular lines 189-211 and 284-298 – for more detail.
