The isolation of the poles makes it very easy to see if the planet is cooling or warming. The energy from our suns output, even minor changes that affect our oceans can change the energy balance towards or away from glaciation. There are many factors that push us one way or the other. My purpose here was show that it was not CO2 driven and that the best course of action today, in our cooling world, was to be ready for the cold that is most cetainly coming soon.With respect to the relatively recent transition from a greenhouse planet to icehouse planet, plate tectonics were responsible for thermally isolating the polar regions from the warmer ocean waters which lowered the temperature threshold for glaciation at each pole with each pole's glaciation threshold being different due to the differences in how they were thermally isolated (continent parked over the pole surrounded by ocean vs ocean over the pole which is thermally isolated due to surrounding lands). As temperatures declined due to natural forces orbital forcing triggered glaciation. Which there have been ~30 such glaciation events in the last 3 million years.
