text: pumping co2 into the bottom of the ocean to reduce this green house gas. is this method a really ood idea? visit this website for the article http://www.abc.net.au/science/news/stories/s1599675.htm 4 years ago i worked on carbon sequestration projects in australia and internationally. this included researching biological, geological and ocean sequestration of co2.   there are pros and cons of all these processes, but i see many more pros.  you only have to look at statoil's sleipner project in norway - they have been sequestering co2 into high saline aquifers since 1996.  they have, in fact stopped 1 million tonnes of co2 from entering the atmosphere per year, the equivalent emissions of a 150mw  coal fired power plant in the us.  i think it is a great solution until we can move towards a hydrogen economy.
