Explain why the rise of the oceans pH this time is different from the past situations?

Answer 1

It has not seen any real changes in generations. There are localized situations where pollution has caused variance's, but on the whole the oceans are the same PH as 1000 years ago. The concern among extremists groups is a lowering PH, not an increasing one.

Our Oceans are the primary source of absorbing CO2. Some groups believe that the rise in man made CO2 will someday cause a PH change. They fail to realize many factors that govern the absorption of CO2 by our Oceans and the small portion of CO2 man actually makes. Currently man produces about 6% of all CO2 and most of this from items that would create CO2 in any event.

I have added a link from an actual science report from Stanford (rather then reactionary opinion sites). It states that it does not look as though PH was ever lower then 0.6 point slower then what we see today (8.179). They created models with WILD volumes of CO2 in our atmosphere (currently 0.38% up from 0.03%) reaching over 1% on total volume and found a possible change of 0.6. This volume is not a tolerable level of CO2, nor a realistic one.

Extremists sites try to point out seasonal variations as proof of long term impact changes, while ignoring long term data. The most reactionary sites claim a drop of 0.02 (almost zero) and cover too short a period to be of any value. Climate and world changes must be kept in the term of a larger picture and time frame. A few years is merely seasonal, or decade based variations.
