Scientists and The White House, say Ocean Acidification
is well under way.David Kramer
The scale of effort required to buffer the OCEAN’S ACIDITY is mind-boggling.
The annual mass of the compounds required is about an order of magnitude more than the 2 GIGATONS OF CARBON absorbed by oceans each year, says Ken Caldeira of the Carnegie Institution of Washington.
That works out to about 30 cubic kilometers of limestone per year, he says. According to WHOI, that is 30 times the amount of limestone mined each year for cement production and all other purposes. That material would somehow need to be distributed more or less evenly throughout the oceans.
