The shells of marine snails – known as pteropods – living in the seas around Antarctica are being dissolved by ocean acidification according to a new study published this week in the journal Nature Geoscience. These tiny animals are a valuable food source for fish and birds and play an important role in the oceanic carbon cycle. Read full article

And we're talking about LONG before mankind even started to release greenhouse gases and what not! So surely, marine snails have adapted in the past to much more drastic climate changes than what we've seen in the past 50-100 years. Besides which, the oceans today aren't even quite acidic, though maybe somewhat less alkaline than 10-20 years ago. Climate change today, even despite greenhouse gases released by humankind as of late, is still mostly about natural cycles - first and foremost from the sun (and cosmic rays), and also ocean cycles, earth rotation patterns, volcanic/seismic activity, etc.!!!
