So, have the biological activity of these Pelagibacterales been incorporated into the Climate Models?
No, and you can tell by the s suffix on the word model. If there was a model that actually worked we would only need one.
Well they have to first start factoring clouds into their computer models before they can factor these bacterial effects. But knowing corrupt statists as we all know them, my guess is they will just use a constant to represent cloud formation and negative feedbacks. Then those bacteria can be factored into the model, and we will all hear how CO2 is killing the bacteria through increased acidity. Even though the ocean is akaline and not acidic.
