Go study ocean acidification.
The oceans are alkaline, not acidic. They are not even close to acidic. Perhaps you need to study a bit rather than simply spew inaccurate buzzwords.
So what if oceans are alkaline? If pH goes from 8.0 to 7.9 that IS acidification. The water IS more acid then before. No one said the oceans were acid. It's like when then the temp "warms" from 10F to 20 F. Nobody's saying it's warm outside. Your argument here just indicates to me that your supposed scientific knowledge is just parroted information from God knows where, certainly not a science text!!!
