Now one could argue that an impact of that sort, onto either the open waters of the St. Lawrence or the Laurentide ice sheet, could have vaporized a good deal of water and ice, thus creating a large tsunami that funneled up the St. Lawrence and then broke through to glacial Lake Vermont, and then set off a chain of events that lead to the draining of Lake Vermont and Lake Agassiz, and that could very well satisfy the proxy evidence in the Younger Dryas boundary layer.

Presenting such alternative figures confuses and undermines the public understanding of the actual science, which is an understanding about the driving mechanisms of sea level rise: thermal expansion of ocean water, melting of mountain glaciers and complex dynamics of large ice sheets — in correspondence again with projected temperature rise, that is in turn a product of projected rises of greenhouse gas concentrations using calculated estimates of climate sensitivity, together creating a net disturbance in Earth's energy balance, the very root cause of anthropogenic climate change.
My research on the Pliocene centers on the relative roles of altered ocean circulation and greenhouse gases in creating the period's increased temperatures and sea levels, as well as its reduced sea ice and continental ice sheets.
