A fascinating piece of sleuthing that has uncovered reports of liquid co2 on the ocean bottom and these have an origin in 'white smokers' – vents near mid ocean ridges and plate boundaries that spew out while columns of fluids, water containg compounds of barium, calcium and silicon, and blobs of liquid co2 – see http://chiefio.wordpress.com/2011/12/10/liquid-co2-on-the-ocean-bottom/. Potentially, this is capable of blowing away the current super scare story -ocean acidification. See also the comments and the idea underwater volcanoes producing co2 drown out human emissions by X amounts … and X in this case is really really big.
Meanwhile, whilst on the energy front, at http://blog.newenergytimes.com/2011/12/04/slides-from-sept-22-nasa-lenr-… is an update on the Rossi experiment – did it go wrong? Is it on course? Nobody knows.
