Roger, CCS is a response to the cause but not the effect, which is heat accumulation in the upper layers of the ocean and the implications of that storage, which are storm surge and sea level rise. These are implications that will last a 1000 years due to the thermal inertia of the ocean and CCS will do nothing to reduce them.
Sequestering surface heat in the deep ocean would mitigate those consequences however as it produces energy that would replace fossil fuels. The potential also exists to tie this option in with Greg Rau's supergreen hydrogen production that would sequester CO2.
Rather than advancing an ideological agenda it seems to me we should be advancing the best technical approach.
