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.
