It’s about cloud physics. So he’s well qualified in this field. Climatologists are least qualified
to talk about real science behind climate in climate science. Because they’re data modelers, data miners, playing data to feed their models, not working on real science behind nature. Our resident board expert-on-everything doesn’t understand the differences between climate science and climatology. I found it long time ago, somehow always forgot to point it out to him.
Cloud is the largest source of uncertainty in the studies of global warming. Inability of mainstream climate models to simulate cloud behaviors accurately is the main reason why I don’t trust their models’ results. It’s well known their model simulations struggle with cloud-radiation physic.
