science is not written in stone and unchanging.... that is true.

developments occur in mathematics and physics as well as other sciences, including ethics. yet while a scientific "theory", ie. valid scientific experiments to test hypotheses, can bring new insights into a science, its sensible to accept that which is considered valid in science rather than to disparage the lot on vague concepts that seek to discredit real science, eg AGW.
