September 19th, 2013 by Warwick Hughes Ken Stewart and Jo Nova have reported on the BoM claim. BoM mean T data for the 12 months September 2012 to August 2013 was the warmest on record for their dataset. You can not make a 12 month average of your choice – I downloaded all monthly anomaly timeseries and built a full timeseries of monthly anomalies from 1910-2013. The only “international” surface temperature data I can find updated through August is GHCN CAMS from KNMI ClimateExplorer. Then we also have the NASA lower troposphere satellite data from the University of Alabama at Huntsville (UAH) commented on by Ken and Jo. It is clear from the graphic that the BoM claim is not robust.
