I first came upon the concept of “Canfield Oceans” in a fairly brief reference to it in Gwynne Dyer’s 2008 book “Climate Wars”.

I was shocked to think that such a mechanism has a realistic possibility of turning Global Warming into not just a human extinction event – but extinction of most life on earth – as apparently happened in 4 out of the 5 major mass extinctions in Earth’s history (the 5th being the asteroid that did in the dinosaurs).

However, I read more about the idea in Peter Ward’s 2007 book “Under a Green Sky”. (http://energyskeptic.com/2011/will-global-warming-drive-us-extinct/)

I was lucky to pick up that book for a couple of bucks off the discount table at a major bookstore. A half dozen or so copies of it had presumably found their way there because they were lousy sellers and nobody was interested in them.

That is, it would seem nobody was interested in the possible imminent (in geologic terms) extinction of all (90%+) life on Earth.

‘Nuff said!
