I'm assuming geophysicists and atmospheric physicists are on the climate change bandwagon. This leaves the "soft" condensed-matter physicists and statistical physicists, who should have more of a systems-thinking mindset.

Among astrophysicists, those working on [magneto]hydrodynamics probably have the skill set and the tools to switch fields to atmospheric dynamics if money becomes available.

Ah, the sociology of science...
