See below for reasonably convincing numerical treatment of the permafrost
runaway event. It claims to shows that, with political and technological
lag, we are likely to cross the tipping point and will be powerless to stop
runaway climate change without geoengineering

I like your idea and will start looking up the macroalgae citations found at
your site.
But I suggest (as did Greg Rau) that you investigate the biochar alternative to
your proposed conversion through biogas. I see three main benefits to biochar
over your CCS option as it
Ron,
How perfect is the nutrient recycling when you convert macroalgae to charcol?
Is there any energy left over after you lift the macroalgae (and some water) out of the water and remove all the water from the macroalgae in order to make char?
