Do you know why this isn't already happening at a pace to keep up with the changes they are measuring? Do you expect that the effects you mention are currently, but will soon catch up? I am honestly curious.
Algae/cyanobacteria blooms are already a reality [1]. The ocean is such a big system though, that I wouldn't expect the long-term effects of these blooms to be observable in a timeframe measured in decades.
A predator-prey model is essentially never just a stable population for both. Instead, you go through periods of increasing prey -> increasing predators -> decreasing prey -> decreasing predators.
Here the prey would be atmospheric carbon dioxide and the predators would be the plankton.
Well, plankton does. Atmospheric carbon increases and (potentially) decreases, and the question I responded to wanted to know why plankton didn't respond to an increase in supply by having already come into existence in the past so that the atmospheric concentration never varied. It's because (just like the predator-prey model) it's difficult for the feeding population to respond in the present to an increased future supply of food.
Its an anlogy, not a syllogism. It would seem enought that Co2 may be correlated with breeding. Which may or may not be technically correct, but its at least a coherent thought.
