weather happens, sometimes there are records …

Perth has now had it’s wettest September on record, possibly a result of the record ice of Antarctica:

WA rainfall is normal, and NOT affected by climate change/global warming/global climate disruption or carbon pollution, whichever term is used today:

Update 39 years of Perth dam catchment rain index 1975-2013

September 22nd, 2013 by Warwick Hughes

Will update the chart from time to time till end October. Blue line is a 5 year average – the average of all 39 years is 909mm. There are several links to earlier relevant information in this May 2013 article – Ongoing decline in efficiency of Perth Dam catchments – reply from WA Minister
Prof Tim Flannery in Jun 2004 saying “Perth will die”
2002 article from The West Australian discussing catchment management

Warwick has more on records: BoM claims Australia has had warmest 12 month period – not supported by some NASA and NOAA temperature data September 2012 to August 2013

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.
