CO2 geo-sequestration is one way of mitigating climate change by pumping our problems deep underground and praying that they don’t resurface any time soon. The idea is that the CO2 dissolves into the pre-existing groundwater and stays there. However, lots of weird things happen when a significant amount of CO2 dissolve into water. One of them is called density driven fingering, and it serves to mix up the water, increasing the rate of absorption. This increases the rate at which we can stave off irreversible climate change, and we need to know more about how to use this process for our benefit.
