Yes. A few degrees of temperature fluctuation are already having a significant impact on marine ecosystems (coral reefs). Making all of the world's ocean water more alkaline is pure insanity. It is extremely likely to cause mass extinctions of organisms which evolved to live at a specific water pH level. These extinctions will reverberate through the entire food chain, all the way up through commercial fisheries.
Ecosystems are complicated, and no one fully grasps all the variables. Climate change needs to be addressed, of course, but drastic interventions are likely to have drastic and unforeseen consequences.
