Is the Anthropogenic Global Warming hypothesis falsifiable?
Scientific theories must make predictions that not only bolster the theory if the predictions come true, but also falsify the theory if the predictions turn out to be wrong. Some climate skeptics believe that the AGW hypothesis is impervious to falsification, short of waiting several decades to directly it, and pending that test, climate scientists and in particular climate modelers have boundless latitude to massage their theories and models to match what has become their pet hypothesis.
