There are always scientists who are working to refute the currently accepted model in pretty much every field of science. This is one of the strengths of science as practiced today. However, their existence does not suggest that their hypotheses are valid. It does mean we need to be making decisions in a world where challenges of hypotheses are constantly arising. I don't deny the laws you mention. Why would you even suggest that? But, I suspect that climatologists know about those laws, as I don't know how anyone could get even just a BS without knowing these laws, as they are at least proximate to pretty much every field of natural science. I don't believe you can find a climate scientist who doesn't know these laws very well.
