slowly dying forests …

As usual, the usual culprits suggest it’s the weather that is mainly responsible, which usually leads into blaming climate change. Truth is, the landscape has been changed more from land clearing, logging, dams and water harvesting, and the introduction of pests and diseases.

2010 update 36 year Perth dams catchment rainfall trend

January 1st, 2011 by Warwick Hughes

The Perth region has had a record dry year and this is shown in my graphic of 36 years of Perth dams catchment region May-October rainfall.
Perth catchment rain trend 1975-2010
However there is no statistically significant evidence the catchments are experiencing a continuing decline in rainfall – as expressed in the slogan “our drying climate” – the greenhouse doomster story so beloved by Perth politicians and water supply meisters – all so anxious to justify their profligate spending on seawater desalination.
One year does not make a trend on which to base water supply policy.
Stunning ignorance and lies surround Perth water supply policies
2009 update – Perth dam catchments rainfall still normal, Govt building $Billion seawater desalination plant #2
There never was a rain shortage to justify seawater desalination for Perth’s water supply
