A poll of climate scientists worldwide revealed that only 56 percent believe humans are the cause of global warming; hardly the consensus that environmentalists allege.

Claims that reports from renowned U.N. climate scientists represent a scientific consensus that human activities are causing or will soon cause significant and generally harmful global warming ignore uncertainties noted in the reports themselves, internal inconsistencies in the supporting data, inconsistencies among the various climate models, and many studies that have reached contrary conclusions.
