[RWL1: Greg (overly modest?) was himself the first author of this
excellent 2012 plea for more thought needed on means of reducing ocean
acidification - the topic of this thread, with an SRM slant, started
yesterday by Andrew. Unfortunately behind the usual Nature paywall,
fortunately I found hi above Nature contribution, with its strong CDR slant, at:
http://www.homepages.ed.ac.uk/shs/Hurricanes/Greg%20Rau%20ocean%20carbon.pdf
I recommend it strongly and thank Greg for citing it.

[RWL2: Only released this past few weeks, it is at:
http://www.thirteen.org/programs/nova/#lethal-seas
Agreed that NOVA is not talking Greg’s CDR option search, but the video
is indeed “sobering” - and highly supportive of Greg’s concerns.
A bit more also below.

RWL3: Ref. 17 is pertinent:

an article by Kwiatkowski et al - also mentions CDR.)
