How's this for a feedback loop?
Ice sheets build up lowering sea level → reduced water load leads to increased mid ocean ridge volcanism after a 10-20 kyr lag → volcanism releases iron → iron causes plankton blooms → atmospheric CO₂ goes down → ice sheets build up

Increased hydrothermal iron inputs from mid-ocean ridges, triggered by ice-age sea-level falls, supported higher surface primary productivity during the last two glacial terminations, according to pro...www.nature.com
