Thank you for the question Michael. My understanding is that the global warming impact of the "bottom up" heat from the ocean in the models is closely related to the level of offsetting cooling from natural (and other) GHG draw down from the atmosphere and the Oceans. In other words, rates of natural GHG uptake in the Ocean, and draw down from the atmosphere and ocean through other means, are key elements in the long term modeling that could presumably also be impacted by applying "bottom up" and "opening up" cooling techniques. The question is whether there is any modeling of the balancing levels and potential time scales for the GHG processes that would give some idea of the needs and types of potentially necessary cooling processes.
