New paper finds ice ages explained even with constant levels of CO2. From the journal Nature.

CO2 is not needed to drive big shifts in the climate like the transitions in and out of the ice age. Instead, changes in sunlight intensity due to slowly evolving irregularities in the earth's attitude and movement around the sun, i.e., Milankovitch cycles, might be to blame. This idea applies only to the Northern hemisphere because of the unique geography there.

We know that changes in the atmospheric levels of CO2 have followed changes in temperature in the past according to deep ice core samples. This paper offers a suggested mechanism behind the changes in temperature. Such changes evolve over several hundred years.
