Is it true that a polar landmass on a thoroughly warmer Earth would develop distinct geological and climatic regimes?

Yes. Paleoclimate and modeling evidence consistently indicate that a significantly warmer Earth alters high-latitude climate dynamics, leading to distinct polar environmental and geological regimes.

The analysis

The claim posits that a polar landmass on a thoroughly warmer Earth would develop distinct geological and climatic regimes. This is a specific, empirical geological/climatic hypothesis. Multiple paleoclimate and Earth system studies (e.g., Papers 2, 4, 7, and 9) show that past warm epochs experienced pronounced high-latitude temperature amplification, altered polar ice sheets, and shifted regional regimes. No papers refute the core premise that warmer global states drive distinct polar regimes.
