Chinese peer-reviewed paper questions AGW hypothesis

Yet another paper questioning the falsified hypothesis of AGW, this time from China, the world's most populated country and the greatest emitter of CO2.

As CO2 science's  Idsos report:

"Fang et al. come to the following conclusions.

First, "global warming is an objective fact," but there is "great uncertainty in the magnitude of the temperature increase."

Second, "both human activities and natural factors contribute to climate change, but it is difficult to quantify their relative contributions."

Third, with regard to the IPCC claim that "the increase in atmospheric concentrations of greenhouse gases (including CO2) is the driving force for climate warming," they note the following four problems:

1.  "It remains unclear how the human and natural factors, especially the aerosols, affect the global temperature change," 
2.  "Over the past century, the temperature change has not always been consistent with the change of CO2 concentration," since "for several periods, global temperatures decreased or were stable while the atmospheric CO2 concentration continuously increased," 
3.  "There is no significant correlation between the annual increment of the atmospheric CO2 concentration and the annual anomaly of annual mean temperature," and 
4.  "The observed significant increase of the atmospheric CO2 concentration may not be totally attributable to anthropogenic emissions because there are great uncertainties in the sources of CO2 concentration in [the] atmosphere."

Challenge alive and well, AGW alarmists fail to claim $10,000

Peter Laux

I have just had an email exchange with Peter Laux to see if his challenge is still active.The challenge was issued over a year ago (8/11/10) HERE on the "CLIMATE GUY" site of   Denis Rancourt. Denis is a former Professor of Physics from the University of Ottowa and an environmental science researcher.

The challenge -

Peter Laux, Locomotive Engineman from Australia, “will pay $10,000 (AUS) for a conclusive argument based on empirical facts that increasing atmospheric CO2 from fossil fuel burning drives global climate warming.”

Peter replied: ".....yes, i'ts still active and "forbidden' by the thermophobes, they know its a "hiding to nothing" to challenge, so ignore it."

The  hypothesis that man-made emissions of CO2 are causing runaway global warming has been falsified more than once. As more peer-reviewed papers are released questioning the hypothesis, perhaps the Alarmists will thrown up their hands, say they were wrong and Peter can put his money to a better use.
