Top climate scientist warns: the warming is exaggerated and we cant stop it anyway
Greens leader Bob Brown claimed the Brisbane floods were caused by coal-miners:
Its the single biggest cause, burning coal, for climate change and it must take its major share of responsibility for the weather events we are seeing unfolding now.
That one statement alone - nonsensically false, alarmist and opportunist - should have reduced him permanently to a figure of fun in a healthy democracy.
And now Julia Gillard claims we need nothing less than a great tax on carbon emissions, to totally transform our economy, if we are to help save the planet from apocalyptic man-made warming.
Why do journalists credit these two shameless alarmists and their fraudulent, ruinous schemes to fix a problem that exists nowhere but in discredited computer models?
On Monday this week, one of the worlds top climate scientists exposed both Brown and Gillard for the dangerous shysters they are
Heres some of that that damning testimony of John R. Christy, Distinguished Professor of Atmospheric Science, Alabamas State Climatologist, Director of the Earth System Science Center at the University of Alabama in Huntsville and former Lead Author of IPCC assessments.
The floods were nothing unusual, and part of natural variability
The tragic flooding in the second half of 2010 in NE Australia was examined in two ways, (1) in terms of financial costs and (2) in terms of climate history.
First, when one normalizes the flood costs year by year, meaning if one could imagine that the infrastructure now in place was unchanging during the entire study period, the analysis shows there are no long-term trends in damages. In an update of Crompton and McAneney (2008) of normalized disaster losses in Australia which includes an estimate for 2010, they show absolutely no trend since 1966.
Secondly, regarding the recent Australian flooding as a physical event in the context climate history (with the estimated 2010 maximum river height added to the chart below) one sees a relative lull in flooding events after 1900. Only four events reached the moderate category in the past 110 years, while 14 such events were recorded in the 60 years before 1900. Indeed, the recent flood magnitude had been exceeded six times in the last 170 years, twice by almost double the level of flooding as observed in 2010. Such history charts indicate that severe flooding is an extreme event that has occurred from natural, unforced variability.
The world isnt warming anything like as fast as the global warmists models warned it would
As noted earlier, my main research projects deal with building climate datasets from scratch to document what the climate has done and to test assertions and hypotheses about climate change....
I have repeated that study for this testimony with data which now cover 32 years as shown above (1979-2010.) In an interesting result, the new underlying trend remains a modest +0.09 C/decade for the global tropospheric temperature, which is still only one third of the average rate the climate models project for the current era (+0.26C/decade.)
There is no evidence of acceleration in this trend. This evidence strongly suggests that climate model simulations on average are simply too sensitive to increasing greenhouse gases and thus overstate the warming of the climate system ...
Trying to stop global warming with things like a carbon dioxide tax or emissions trading is a waste of money
The evidence above suggests that climate models overestimate the response of temperature to greenhouse gas increases. Even so, using these climate model simulations we calculate that the impact of legislative actions being considered on the global temperature is essentially imperceptible. These actions will not result in a measurable climate effect that can be attributable or predictable with any level of confidence, especially at the regional level Thus, if the country deems it necessary to de-carbonize civilizations main energy sources, sound and indeed compelling reasons beyond human-induced climate change need to be offered.
