Very little in science is called "A Fact".
ie "The theory of Relativity"
Only RATS get to call "global warming" "acid rain" "ozone layer" theory's, FACTS.
Remember how settled the science was in the build-up to the Y2K scare? Worse yet, it's foregone conclusion would be manifest on a date certain, just to drive the point home.
Refresh my memory - how'd that turn out?
CA....
