Does science ever actually prove anything?

Below is a link to a letter signed by a large number of climate scientists about the reality of climate change. One provocative statement they make in defense of their work and against climate change skeptics is that “There is always some uncertainty associated with scientific conclusions; science never absolutely proves anything.”

This letter caused a stir among other scientists, some of whom wrote and signed another letter making the argument that: “There is no reason to doubt the laws of physics governing acceleration and momentum. These laws are the basis for a large number of industrial operations, transportation and numerous other activities.”

An interesting exchange that gets to the nature of science and scientific knowledge.
