The fact is modern sea life cope perfectly well with pH levels that vary by .4 pH units over a period of less than one year, as shown in this graph from the Monterey Bay Aquarium of incoming seawater:

Study shows modern oceans are more alkaline than past 250 million years
While eco-alarmists would have you believe the oceans have "acidified" to dangerous pH levels, a paper published in Nature finds that the modern ocean pH of about 8.1-8.2 is actually the most alkaline the oceans have been over the past 250 million years. During this time corals, phytoplankton, and indeed most of the ocean biomass have evolved. The paper shows a mean pH of about 7.7 over the past 250 million years, whereas the alarmist and frequently incorrect IPCC predicts ocean pH will drop to 7.88 (~0.2 pH units) under a "business as usual" scenario by 2100.
