Ice age, plate tectonics and PIE

Will the following surmise have an effect on the spread of PIE
languages prior to Eurasian de-glaciation, say, 10000 carbon-14
years ago?


"Plate tectonics is an important process influencing when ice ages
occur, and the position of the continents is probably one of the
most important factors controlling long periods of multiple
glaciations....Over the past 15 million years, the continents have
risen about 600 meters (2000 feet) on average. The uplift of the
Himalayas and the Tibetian Plateau probably contributed to the
initiation of the current cool period."
