Yes. It's the classic ice skater effect. Climate gets warmer => Ice (on mountains) melts. Molten ice = water flows down into the ocean, moment of inertia of the Earth is reduced => Earth's rotation speeds up. Just to put things into perspective: The elevation of the land surface at the Earth's south pole is over 2800m above sea level. The highest point in greenland is over 3600m above sea level.
