Here is just one example of why you never say science is settled.
Are you wondering how many planets are in the Solar System? Until just a few years ago, there were 9 planets in the Solar System. However, the International Astronomical Union decided that Pluto is no longer a planet, so there are now only 8 planets in the Solar System.
Why is Pluto not a planet? We have a whole article that discusses this in great detail, but it happened because astronomers discovered a new object larger than Pluto out beyond its orbit. This object is called Eris, and it's at least a few hundred kilometers bigger than Pluto. The IAU wondered if this object should be considered a planet too?
How Many Planets are in the Solar System?
For years even on schools if a child was asked on a test how many planets there were on the solar system and did not answer 9 they were given an incorrect answer. So does this mean we go back and correct all those tests based on that settled science? The fact is the science of global warming is far from settled, so before we get to the point where we have to go back and start changing text books again, perhaps we allow for research on the subject and not political mandates based on theory.
