Rampino and Self argue that this event caused a 5 degree Celsius decrease in global temperatures, though it probably did not cause the last ice age even though it coincided with its (*) beginning.
Evidence for this event includes the burial of stone tools under layers of YTT and a layer of sulfates found about 2500 meters into the GSP2 ice core found in Greenland.
