The problem with using terrestrial biomass residues to combat CO2 accumulation
is that there is a limited supply that is available for human use without doing
environmental damage. These consist mainly of crop residues from high yielding
agriculture and managed forests. There are competing

I agree with Alvia about some of the environment left. I call those who oppose
most new environmental engineering Dark Greens. They can be easy to detect
because many if not most of their arguments end with there are just too many

Perhaps you should estimate the cost first. How much straw per ha do you need
to insulate enough to get 50% reduction in heat flux? Or to cover, to make it
simpler. The sea area to be covered would be something on the order of the
area of a hurricane. Purchase and shipping costs for the

Yes, large amounts of methane suddenly released from hydrates or from
overturning stratified lakes could be explosive if somehow mixed with the right
amount of air. I was referring to the slow release of CH4 from tundra and
small shallow lakes. Slow in terms of reaching the lower explosive
The problem is that there is only one facultative methanotroph known and it
would probably not do well in a bioreactor that is open to the atmosphere (and
other bugs) and fed with a substrate other than methane. I am looking into the
possibility of a bioreactor that is fed methane for a while
For those of you interested in learning more about microbiology, may I suggest

exposition of the microbial world, which is responsible for the mineralization
of organic matter in soils and sediments, and the thermodynamic

Greg is right about the importance of doing the numbers. I was surprised at
how carbon efficient it would be to barge crop residue to the sea. I thought
that much more fuel would be required than it turned out.
To me it is all about the carbon. If an engineer wants to remove carbon from

In terms of carbon burying biomass in sediment is a much more efficient use of
biomass than combustion, as Metzger and Benford developed in 2001. It helps to
think about it as global recycling. Put the excess carbon back in the

I won't try to guess at questions 1 and 2, and I am not too sure about the
