Albert Einstein once said, “No amount of experimentation can ever prove me right;
a single experiment can prove me wrong.” Einstein’s words express a foundational
principle of science intoned by the logician, Karl Popper: Falsifiability. In order
to verify a hypothesis there must be a test by which it can be proved false. A thousand
observations may appear to verify a hypothesis, but one critical failure could result
in its demise. The history of science is littered with such examples.
A hypothesis that cannot be falsified by empirical observations, is not science.
The current hypothesis on anthropogenic global warming (AGW), presented by the U.N.’s
Intergovernmental Panel on Climate Change (IPCC), is no exception to this principle.
Indeed, it is the job of scientists to expose the weaknesses of this hypothesis
as it undergoes peer review. This paper will examine one key criterion for falsification:
