More dust, less sunlight, colder oceans, but more dust means that more dust falls on the oceans, which means the more iron fertilization of photosynthetic organisms there is, the higher the level of photosynthesis, so the more CO2 is converted into biomass, so more organic carbon falls to the sea bed, so the more atmospheric carbon disappears into the ocean sink, and also the wider the oxic band at the oceans surface and so more methane is oxidized on the way to the surface.
