[geo] Would carbonate buffering fertilize the oceans?

2009-01-31 Thread dsw_s
Adding calcium/magnesium carbonate to the ocean to offset acidification and increase CO2 uptake would increase the concentrations of carbonate, bicarbonate, and total inorganic carbon (if I've got it straight), while decreasing the concentrations of dissolved carbon dioxide and undissociated carbo

I dimly recall that tall trees lose sap transport capacity to cavitation: the column of water in the tube of xylem cells is under tension, with water being pulled up by evaporation rather than just pushed up by active absorption of water in the roots, so whenever a gas bubble forms in the wood it

Hello Andy: Thanks for the post! My colleague, oceanographer Jim carton and I wrote a rough draft last year on an idea of sustainably harvesting wood from the Black Sea drainage basin including the Alps, rafting down the logs and sink to the bottom of the Sea. Tom Schelling mentioned to me of th

It seems as though in vernacular plain English, it is. My inclination would be to change the jargon to avoid confusing the public unnecessarily. The deniers are doing plenty of that on their own. On Jan 31, 10:42 am, David Schnare wrote: > We have discussed this before.  Solar radiation manage

We have discussed this before. Solar radiation management is not mitigation. It is a form of adaptation of limited use (several decades to centuries) and no prevention to harm to oceans. Carbon sequestration (eg. OIF) is a form of mitigation, but is not mitigation as defined by climate activists
