I don't think you've any basis to that statement, in that CO2 absorbtion by planktonic photosynthesis is a significant thing. 50% of ALL photosynthesis (by which CO2 is converted into organic Carbon and Oxygen is released) involves oceanic phytoplankton.. If you think that is not "significant', then you're more of a moron than you've led us all to believe. news.nationalgeographic.com link.springer.com smithsonianmag.com Some folks also assert that the amount of oxygen released by marine algae (phytoplankton) equates to 70-80% ecology.com One, plankton dies off and the captured CO2 is released in a cycle. There's no net uptake. This is clearly not true. If it was, there would be no such thing as "Marine Snow", which are the organic remains of various marine algae that sink to the ocean depths. SOME algae do die and decay on the surface, but their decay releases methane. But Coccoliths and Diatoms SINK due to their exoskeletons. CO2 is absorbed by the ocean and is converted into Carbonic Acid. CO2 is absorbed by the oceans dependent upon temperature and akalinity (both of which vary around the global seas). Phytoplankton, which live near the surface (sunlight) draw this CO2 from the water, NOT the atmosphere. When the CO2 is converted by photosynthesis into organic carbon and oxygen, it decreases the saturation point and permits more atmospheric CO2 to be absorbed by the ocean water. Again, UNLIKE terrestrial plants, which draw their CO2 directly from the atmosphere, Marine Algae primarily draw it from the surrounding water. Decreased Marine Algae populations mean less CO2 is being converted via Photosynthesis, thereby permit CO2 saturation levels to peak. To reiterate, alkalinity levels of the oceans vary GREATLY around the world. Some scientists have also suggested increasing alkalinity would permit greater amounts of CO2 to be absorbed from the atmosphere. earth.ox.ac.uk Using Secchi disk data, with nearly 1/2 million data points going back nearly 100 years, it was determined that, SINCE 1950, there has been at least a 40% decline in phytoplankton in the oceans. scientificamerican.com nature.com So.. there AGAIN (since I've posted this data in various forms NUMEROUS times already) is the argument.. 40% decline in Marine Algae that are responsible for AT LEAST 50% of all global photosynthesis over the SAME TIME PERIOD we've seen a 50% increase in atmospheric CO2. But NO, ZILCH, ZERO Climate models have incorporated that global influence of 25% less global photosynthesis since 50% of PS being terrestrial flora, and the other 50% being marine algae, which has diminished by 40-50%, resulting in a 25% decline in photosynthesis globally.. And I haven't even factored in any variations in terrestrial photosynthesis.. The logic is IMPLICIT, if not obvious. Certainly IT DEMANDS to be factored into climate change models, as well as research being conducted to determine the reason marine algae levels have declined and ways to mitigate the problem (Iron Fertilization?).. Now go away.. you bother me.. Hawk
