Andrew Lenton and colleagues at the National Center for Scientific Research used a model to calculate the changes in ocean–atmosphere carbon balances for the period 1975–2004 that included the impacts of changing ozone concentrations. The researchers compared two scenarios: one that accounted for ozone depletion and another in which no ozone alterations occurred. It's possible, but I always find "models" to be suspicious, especially when related to finding new reasons to create excitement over Ozone holes. Phytoplankton will release chemicals that promote cloud formation to shield them from the sun. Thus, if UV radiation is inhibiting phytoplankton, it would stand to reason they would release Isoprene or dimethyl sulfide to protect themselves. Was this incorporated in their model? However, I will state that it's encouraging that the depletion of phytoplankton was acknowledged. It's a good start. Hawk
