This snowpack accumulation near the poles, which gets its water via the Arctic and Antarctic oceans, that in turn rob it from equatorial latitudes of our oceans, also results in a reduction in the earth's spin axis moment of inertia and causes the spin rate to increase as evidenced in the recent history of the rate at which Leap Seconds are added to our calendar (see Wysmuller's Toucan Equation for more on this evidence that during this warm time with much greater polar humidity, earlier seasonal, later seasonal and heavier snows are beginning to move water vapor from the oceans to the poles to re-build the polar ice caps and lead us into a global cooling, while man - made CO2 continues to increase http://www.colderside.com/faq.htm).
