Yeah sure...anything you need to say to justify paying your carbon taxes...don't let the facts get in your way.It doesn't change the accuracy of saying there were palm trees in the antarctic during the Paleocene thermal maximum.
Plate tectonics doesn't account for the climate change.
ps you're being played.
The onset of the Paleocene–Eocene thermal maximum has been linked to volcanism and uplift associated with the North Atlantic Igneous Province, causing extreme changes in Earth's carbon cycle and a significant temperature rise.

The horizontal and vertical displacements associated with plate tectonics play a fundamental role in climate change over a wide range of timescales. The solid-earth surface is in direct contact with the atmosphere and oceans and its evolving character affects balances of incoming and outgoing radiation, atmospheric circulation, ocean currents, and the location of elevated terrain suitable for glaciers and ice sheets. Tectonic processes also have important indirect climatic effects through their control on geochemical cycling and the composition of the atmosphere and ocean
