Measurements of dust deposition around the world during the Earth's past three glacial-interglacial cycles indicate that dust input to the atmosphere and ocean increased exponentially with decreasing temperature; climate simulations based on this relationship suggest that the climatic effects of dust may have amplified global cooling and carbon dioxide drawdown during cold times and pushed the global climate into extreme glacial maxima.
