Reduced ocean productivity due to global warming induced thermal stratification has been observed in a dataset covering past 10 years by Behrenfeld et al., Climate-driven trends in contemporary ocean productivity, Nature 444, 752-755, 2006.

Contemporary science is still studying the deep oceanic geothermal vents, where life is found to be both abundant and extremophilic. The temperatures and chemosynthetic reactions, that are the building block of life, at these sites insists that we must take the study of extreme meteorological phenomena to the next level if we are looking for chains of life. Scientific research in varied schools of thought must also be considered considering that the earth and life as we know it dictate the same differences in thought such as Meteorololgy, Geology, Astronomy, Physics and the Biological schools. Your article is well put and well referenced.(http://pubs.usgs.gov/gip/...)
