Fellow nature watchers,
How is your greenery going? Australia’s “Greenery” seems to be abundant. Positively verdant, one could claim. Why? Well, read on.
There has been alot of worldwide Media and science blog traffic about the Queensland floods over the last week. Mainly sheer amazement that such devestation could occur in a first world country. Rio’s floods are bad enough, but how could this happen in Brisbane? Is this just an unlucky act of nature or have the floods been “helped along” by unscientific behaviour ? Let’s look at the raw data – global and local
From the data above it seems evident that strong La Nina conditions are with us again, meaning a general cooling (BLUE) of the eastern equatorial Pacific and reflected in a very warm (RED) western Pacific. One would expect heavier than normal rainfall along the Australian east coast. The historical rainfall graphs for Queensland and Brisbane show that these flooding rains often occur at regular natural intervals at the ends of long drought periods. It would seem reasonable that the Australian authorities should try protect its population from these obvious cyclical dangers.
Reason does not appear to have been victorious in Brisbane. “Success” has apparently been awarded to the Australian environmental movement … again.
More and more evidence is now … flooding in … that many Australian authorities are so “drunk” on the Green global warming hypothesis that many new flood controlling dams, for the last 30 years, all around Australia, have been stopped (desalination plants built instead). Also, the only dam that could have saved Brisbane was kept too full, too late (for fear of an unending drought) … so that (for fear of a dam collapse) huge amounts of water were released on top of the already flooding Brisbane River. What a mess!
Federal Environment Minister Peter Garrett on Wednesday (11 Nov 2009) said he made the interim decision to reject the controversial $1.8 billion plan to dam the Mary River because evidence showed it could kill off endangered species. “The project would have serious and irreversible effects on national listed species such as the Australian lungfish, the Mary River turtle and the Mary River cod – both of those endangered.
It may be time to stop describing south-eastern Australia as gripped by drought and instead accept the extreme dry as permanent, one of the nation’s most senior weather experts warned yesterday.”Perhaps we should call it our new climate,” said the Bureau of Meteorology’s head of climate analysis, David Jones.
And it seems evident again why these flood management errors begin to … flood in:
In 2007 a report examining the Wivenhoe dam’s storage capacity was conducted by the Queensland government and Seqwater. It concluded that neither the Wivenhoe dam nor the Somerset dam, which feeds into the Wivenhoe, satisfies the ANCOLD – Australian National Committee on Large Dams – guidelines on flood capacity.
“When they finally did release, it was because they had received so much inflow this week that they were afraid the whole system would collapse. There is no doubt in my professional opinion that most of the flooding in Brisbane should have been avoided. It is extraordinary to me that people are not asking more questions about this. Brisbane should have been protected by Wivenhoe Dam. Instead, the dam is a large part of the reason the city has flooded.”
Let us hope that in the 2040s, when the next natural flooding rain cycle hits Queensland, that The Greenery is not still flooding politics and Australians.
