A counterargument can be used to attempt to refute the competing view. For example: “Even with a vision, there is no guarantee of success. Some scientists are already saying that we have waited too long and that a runaway greenhouse effect is now a real possibility” (McKibben 95). With this kind of statement, it doesn't give credibility to his claim, because he claims it was said by scientists. But McKibben takes this counterargument even further. “And the fact that China and India are now starting to burn fossil fuels in appreciable (not to mention American) quantities makes the task more difficult” (McKibben 95). This only further supports his opponents' claims, as it provides factual evidence to support the opposing view that the damage has already been done. This choice of counter-argument does not constitute an aid to its conclusion..
