How politics contributed to the January 2011 Brisbane floods : Comments
By Peter Coulson, published 24/1/2011A belief that drought was the prevailing state of Queensland's climate left politicians psychologically incapable of being prepared for flood.

I don't think I will get an informed and unbiassed opinion about the effects of burning fossil fuels from a mining company lobbyist.
Until he presents his data for scrutiny or has it published in peer review journals it remains an unverifiable opinion. Why don't you read this book and see what the historical origins of AGW skepticism are? http://www.abc.net.au/rn/scienceshow/stories/2011/3101369.htm Posted by wobbles, Tuesday, 25 January 2011 1:22:38 AM

Wobbles, would it not be prudent to wait until the IPCC runs its
computer models with the new fossil fuel availability quantities before we get ourselves into a tizz over just how much CO2 will be available ? Posted by Bazz, Tuesday, 25 January 2011 10:54:36 PM

Due to the health risks associated with carbon dioxide exposure, the U.S. Occupational Safety and Health Administration says that average exposure for healthy adults during an eight-hour work day should not exceed 5,000 ppm (0.5%). The maximum safe level for infants, children, the elderly and individuals with cardio-pulmonary health issues is significantly less. For short-term (under ten minutes) exposure, the U.S. National Institute for Occupational Safety and Health (NIOSH) and American Conference of Government Industrial Hygienists (ACGIH) limit is 30,000 ppm (3%). NIOSH also states that carbon dioxide concentrations exceeding 4% are immediately dangerous to life and health[57] although physiological experiments show that such levels can be tolerated for some time.[58]
Adaptation to increased levels of CO2 occurs in humans. Continuous inhalation of CO2 can be tolerated at three percent inspired concentrations for at least one month and four percent inspired concentrations for over a week. It was suggested that 2.0 percent inspired concentrations could be used for closed air spaces (e.g. a submarine) since the adaptation is physiological and reversible. Decrement in performance or in normal physical activity does not happen at this level.[58][59] However, it should be noted that submarines have carbon dioxide scrubbers which reduce a significant amount of the CO2 present.[60] These figures are valid for pure carbon dioxide. In indoor spaces occupied by people the carbon dioxide concentration will reach higher levels than in pure outdoor air. Concentrations higher than 1,000 ppm will cause discomfort in more than 20% of occupants, and the discomfort will increase with increasing CO2 concentration. The discomfort will be caused by various gases coming from human respiration and perspiration, and not by CO2 itself. At 2,000 ppm the majority of occupants will feel a significant degree of discomfort, and many will develop nausea and headaches. The CO2 concentration between 300 and 2,500 ppm is used as an indicator of indoor air quality. Maybe we can evolve in time to breath it:) BLUE Posted by Deep-Blue, Wednesday, 26 January 2011 1:06:50 AM

Carbon dioxide in earth's atmosphere is considered a trace gas currently occurring at an average concentration of about 390 parts per million by volume or 591 parts per million by mass.[25] The total mass of atmospheric carbon dioxide is 3.16×1015 kg (about 3,000 gigatonnes). Its concentration varies seasonally (see graph at right) and also considerably on a regional basis, especially near the ground. In urban areas concentrations are generally higher and indoors they can reach 10 times background levels. Carbon dioxide is a greenhouse gas.
Yearly increase of atmospheric CO2: In the 1960s, the average annual increase was 37% of the 2000-2007 average.[26] Five hundred million years ago carbon dioxide was 20 times more prevalent than today, decreasing to 4-5 times during the Jurassic period and then slowly declining with a particularly swift reduction occurring 49 million years ago.[27][28] Human activities such as the combustion of fossil fuels and deforestation have caused the atmospheric concentration of carbon dioxide to increase by about 35% since the beginning of the age of industrialization.[29] Up to 40% of the gas emitted by some volcanoes during subaerial eruptions is carbon dioxide.[30] It is estimated that volcanoes release about 130-230 million tonnes (145-255 million tons) of CO2 into the atmosphere each year. Here, in a bowl-shaped depression of about 100 m diameter, local concentrations of CO2 rise to above 75% overnight, sufficient to kill insects and small animals, but it warms rapidly when sunlit and the gas is dispersed by convection during the day.[31] Locally high concentrations of CO2, produced by disturbance of deep lake water saturated with CO2 are thought to have caused 37 fatalities at Lake Monoun, Cameroon in 1984 and 1700 casualties at Lake Nyos, Cameroon in 1986.[32] Emissions of CO2 by human activities are currently more than 130 times greater than the quantity emitted by volcanoes, amounting to about 27 billion tonnes per year.[33] Now Iam sure.....Co2 is not anything to worry about:).....earth takes it in....then man lets out out.......and then the people wonder why there getting tired. Interesting. BLUE Posted by Deep-Blue, Wednesday, 26 January 2011 1:22:15 AM

Much blame and shame has been regurgitated in the past few weeks by dopey Journalist, Party faithfuls, retired Engineers with an axe to grind, etc regarding the Queensland 2011 Floods, and it's tragic aftermath. There has been so much idle speculation and conspiracy theories, it behooves Justice Holmes to set a date, and subsequently resolve the issue, once and for all - wishful thinking hmm ?
The Bligh Govt is in full damage control following the publication of SEQW Wivenhoe Dam Maintenance Manual. Pertinent chapters have been blanked out, which indicates to all and sundry, a particularly ominous sign ! Flood Operations Officer Graham Keegan, and CEO Denham acquiesced, this was done deliberately to dissuade would be terrorism ! No surprise. The twin Dams Somerset and Wivenhoe, and 204 other Dams, and weirs, in Qld, are open to the public 24/7 without restrictions. The facilities provided by taxpayers are a real money earner, and enjoyed by all who visit the sites. The Manual is the lynch-pin to the Inquiry. Legal Officers will be scrutinizing it's contents religiously. Moreover, should Dam Officers be found guilty of misdemeanor eg. Opening the 5 Gates contrary to the manual, they forfeit immunity from legal prosecution, and class action from the Insurance Industry and flood victims. Ever since Beattie's drought proofing SE Queensland, and the laying of 450 klms of adjoining pipeline to major Dams; and the white elephant Tugun Desalination Plant @ rubbery $ 1.5 ,water has overnight become a very costly commodity at $2.68 /kl. Water distribution services have risen to $ 446.00 per household. Four quasi-govt entities eg. Allconnex, GCCC etc, manage this gross imposition. Clearly, water retained in Dams is money securely in the Bank. Dumping water downstream would be an act of vandalism. Posted by dalma, Thursday, 27 January 2011 10:51:48 AM

The Labor party believed this and built the desal plant in Brisbane, Melbourne and Sydney. (By the way is the Brisbane desal plant underwater ?)
Left wing ideology goes wrong once again but will they recognise it? Of course not, the Left will continue down the Global Warming path making incorrect prediction after incorrect prediction, and never acknowledging them and Labor govts will spend billions following them and getting it wrong all at our expense.
Queensland could have captured enough water for many years had they built dams prior to this inundation.
