If you're implying that most of climate science is statistical modeling, please be specific and say so. While there is plenty of statistics in the field[1], the majority is basic physical science and dynamical modeling. Equivocation between statistical and dynamical models is surprisingly common on HN and leads me to suspect that a person hasn't taken much time to learn about climate science.
[1] Calling it a single field isn't really fair. It's the nexus of many specialized fields, most of which are purely physical sciences.
